In my application, i have application item that stores employee id.
I have a form where emp_id=application item id and an interactive grid which also has application item in where clause.
In form, the application item value is available and shows as emp_id.
But in interactive grid it doesn't .
Form P1_emp_id =:APP_ID -> Displays emp_id = 1
IG : emp_id = :APP_ID -> emp_id is null.
It doesn't take the application item value although it is there in the session.
Did you try to give 'submit' or 'return item' values? Maybe you should add the item there and it will take the value. Or try 'fire on initialization: yes' and put the page on 'after refresh'. If none of them works then please provide us more detailt to solve this problem, thanks.

I have a form with items P1_APP and P1_USER.
P.S. P1_USER is select list.
Display John
Return 1
Display Andy
Return 2
I need to disable when user selects John.
When P1_USER = 'John', P1_APP should get disabled which is a multi select list.
I created dynamic action on P1_APP, True Action= Disable,Affected element P1_APP
Client condition : Item =Value
Item= P1_USER
Value= John
However this is not working.
I have used similar logic to disable interactive grid items and was able to do so. Why is this not working for form?
EDIT: In Value now i am putting 1 which is return value for John.
However when i select John. It disables P1_App upon clicking. But remains disabled even when i choose Andy.
This works for me using the following configuration.
Create form and report on EMP - everyone has access to that sample data, it is a good idea to post questions based on that.
In the form P3_DEPTNO is a select list with source
SELECT d.dname, d.deptno FROM dept d
Add a page item to my form P3_APP. This is a select list with "Allow multi selection" enabled. Select list has 2 static values.
Create a dynamic action on change of P3_DEPTNO.
Client side condition: Item = Value
Item: P3_DEPTNO
Value: 30 (note that this is the return value for SALES, not display value)
add true action of "Disable", affected item P3_APP
Click true action and select "Create Opposite Action". Save.
When I run this it work. Selecting SALES in the select list disables the item P3_APP and selecting something else enables it.
I use plugin Select2 on Apex.
I have scenario like this:
I have three tables: ROOM, MASTER_STUDENT and MAP_STUDENT_ROOM
One ROOM can have many STUDENT
User can select more than one student(with Select2 from MASTER_STUDENT) when create ROOM
When user edit ROOM, previously selected student show in Select2 item(selected item by MAP_STUDENT_ROOM), so user can remove or add more Student
How to achieve point number 4, item Select2 list of values is MASTER_STUDENT but with default selected by MAP_STUDENT_ROOM?
I found this documentation, but i dont know how to apply it.
I'm not familiar with the Select2 plug-in.
Have you considered using the built-in Popup LOV, which since APEX 19.1 now allows multiple selection.
Whether you're using the Select2 plug-in or the built-in Popup LOV, the issue will be the same. You have a form on ROOM, that's trying to take into account an item that isn't part of the ROOM table (its values are stored in MAP_STUDENT_ROOM). The trick is to populate the item correctly during page load so that the item can correctly display the currently assigned students.
How is the item's Source configured? If it's not, set Type to SQL Query (return colon separated value). Assuming you have a primary key item on the page for the room (e.g. P1_ID), enter a query like the following:
select student_id
from MAP_STUDENT_ROOM
where room_id = :P1_ID
Then set Used to Always, replacing any existing value in session state.
This should get the item to display correctly when the page loads. However, you'll still have to figure out how to map the values back to the MAP_STUDENT_ROOM table correctly when the page is submitted. You'll need to add some logic that first deletes rows from the room (P1_ID) that are not in the selection (e.g. P1_ASSIGNED_STUDENTS). You can use APEX_STRING.SPLIT_NUMBERS to help:
delete from map_student_room
where room_id = :P1_ID
and student_id not in (
select column_value
from apex_string.split_number(:P1_ASSIGNED_STUDENTS, ':')
)
Then you can insert rows that are in the selection but not already in the room.
insert into map_student_room (
room_id,
student_id
)
select :P1_ID,
column_value
from apex_string.split_number(:P1_ASSIGNED_STUDENTS, ':')
where column_value not in (
select student_id
from map_student_room
where room_id = :P1_ID
)
I've not tested any of this code, but it should get the points across.
Another option would be to use an Interactive Grid instead of a list of values item. This is a classic master/detail scenario where students could be added and removed below the form region (typically only done after create).
I have an item to enter email id, and two more items to get the values of first/last name and department of that user which we have given without refresh the page or without enter.
Item 1: ex : a...z#gmail.com (text field)
Item 2 : ex Mechanical (display only)
Item 3 : ex Abinnaya Moorthy (display only)
This should happen when we have given the email id and as soon as the cursor is out from email id the two item values should display.
I have used dynamic action but not getting exact output, please let me know.
On Item 1 make a following dynamic action:
Event: Change (I would recommend 'change', although based on your question, you might also be interested in 'Mouse Leave', although it would trigger DA even when no change in item value occurred, for example when someone just clicked on it and clicked away)
Selection Type: Item
Item: your Item 1
First true action: Execute PL/SQL Code
inserting values into your items Item 2 and Item 3, while using your Item 1 as a condition in WHERE clause
Page Items to Submit: your Item 1
Page Items to Return: your items Item 2 and Item 3
Second true action: Refresh
Selection Type: Item(s)
Item(s): your items Item1 and Item2
Let's say I have 1 field like an email field above. Then I have 50 display only fields that values are coming from (Source) SQL queries that depends on email field. How to refresh this fields without refreshing page, but also without Setting its value manually? I would only like to trigger them to perform their Source SQL query and refresh values on the page.
Setting their values by SetValue action will result in having same queries in Dynamic Action and in Source SQL Query for each field. Also for 50 fields DA would have hundreds of SQL lines and would become not maintainable.
assuming you are working on page 9, and the email field is :P9_EMAIL_ITEM, and the name fields are :P9_FNAME_ITEM and :P9_LNAME_ITEM
The email field is a text field (it doesn't matter what the source is)
The name fields should be display only, and in properties the setting "Based On" should be "Page Item Value", set the source property to type Null.
On the email text field, create a new dynamic action, set the When properties to: Event -> Change, Selection Type -> Item(s), Item(s) -> P9_EMAIL_ITEM
Under the dynamic actions you'll have a "New" event, with a "True" folder, and inside it a new action (probably "Show"). Change its action to "Set Value".
change the setting property so that "Set Type" will be "SQL statement", and write a statement with the following structure:
select FNAME_COLUMN, LNAME_COLUMN
from RELEVANT_TABLE
where EMAIL_COLUMN = :P9_EMAIL_ITEM
Under "Items to submit" select the P9_EMAIL_ITEM.
in the Affected Elements properties set Selection type -> Item(s) and Item(s) -> P9_FNAME_ITEM, P9_LNAME_ITEM
In "Execution Options" select NO for Fire on Initialization
what we did on step 5 is "refreshing" the relevant items, without refreshing the page
I just tested it out and here's what works very well:
On Item 1, create a DA on 'Loose Focus'
Create two true actions for 'Set Value', for both Item 2 and Item 3.
Select Settings > Set Type as SQL Statement.
Write query to fetch item 2 and item 3, base on item 1 (I suggest comparing lower cases of both to make it case in-sensitive.)
Items to Submit -> Item 1
And viola, it's done!
I have an interactive report and a form associated to it. After creating a new entry using the form, my end-users want to put the focus on that specific new entry in the interactive report (it's a lot of entrys, and today they need to scroll down a lot to see the new one).
They also want the same funcionality when updating a row of the report.
How can I do this the correct way in APEX 5.1?
Here is one aproach based on EMP table in apex.oracle.com Create interactive report with edit form. In my case this is page 6 for report and page 7 for edit. Create one hiden item on page six (P6_EMPNO). Add case to your query so in my example it's look something like:
select "ROWID",
"EMPNO",
"ENAME",
"JOB",
"MGR",
"HIREDATE",
"SAL",
"COMM",
"DEPTNO"
from "#OWNER#"."EMP"
ORDER BY CASE WHEN EMPNO = :P6_EMPNO THEN 1 ELSE 2 END, EMPNO
I'm sorting result by EMPNO.
Choose P6_EMPNO in Page Items to Submit section. Go to page 7, select branch(Go to page 6)and click on Target In set items section choose P6_EMPNO and for target &P7_EMPNO.
Now every time you go to page 7, the value of hiden item will be the EMPNO from page 7 and it will apear on top of the region. You can use jQuery to highlight the row and put some validations to update P6_EMPNO only when some data was changed.
I hope this can help you.
easy.
You don't even have to create any additional page items. Change your form DML so that it returns into the primary key page item holder. Then Create a process after your DML process but before the reset cache process. Use APEX_IR API to reset pagination on your IR page, and then set an interactive report filter based on the primary key page item you returned the new PK into. Check the documentation for exact usage.
Apex_IR.reset_report to reset the report pagination and remove any filters.
Apex_ir.add_filter to add a filter = to new primary key
Interesting question, another solution:
Create a item in your report page, something like P3_ANCHOR
Add data-anchor="#< YOUR_COLUMN_ID >#" to your report link attribute
Configure your form page to return the created/modified item id to item P3_ANCHOR in your report page.
Create a Dynamic Action on report page
Action: Execute Javascript Code
Code:
var container = $('body'),
scrollTo = $('[data-anchor="'+$v('P3_ANCHOR')+'"]');
container.animate({
scrollTop: scrollTo.offset().top - $(document).scrollTop()
}, 2000);
Simple solution:
Sort your report descending so that the last created ID will be the first in the IR
This is a very odd question but i wondered whether it was possible to trigger a process that runs an SQL UPDATE when the user leaves this specific page, either by clicking on the breadcrumb, tabs or back button?
I did setup the process to run on the 'Back' button; however i ran into the problem of: What if s/he clicks on the breadcrumb or a tab instead.
I have searched the net and posting this question was a last resort. I wondered if anyone can point me in the correct direction?
UPDATED POST
Page 1:
Includes a text field and a button. The user enters the category into the text field and clicks on the button to proceed to the next page. The button passes the value in the text field to a text field on Page 2.
Page 2:
Two regions on the page. One region holds information about the category - Category name from the previous page, category description, and the category revision number (which is what i'm trying to get working). The second region is a report that pulls the item name and number that are listed under the category in the category text field. A 'View' link is used on the report to load the edit page for the specific item selected. The 'View' link passes the 'category name' (from the category text field) and the 'item number' from the report to page 3.
Page 3
Two regions are used, first region: Lists the Item number which came from page 2 and name of the item (which i use a simple query to retrieve). In the second region: A report is used with two columns: a list of item properties in column 1, and a text field next to each item property in column 2 to hold the value that can be updated. The 'Apply Changes' button has some PlSql behind which looks for changes and updates where required. It updates the relevant fields that have changed, and it then takes the user back to Page 2 (Page showing user the items listed for the category intitally entered).
I cant increase the category revision on the 'apply changes' button on page 3 because the user may complete edits for items under the same category. So i dont know where i can increase the category revision by 1 per vist to a category. P.s I already increment the revision number for each item by 1 if the info has been changed using the 'apply changes' button on page 3.
One way of doing this is by updating the session state of the page items (without submitting the page as normal) via ajax and by calling an Application Process which updates the table, when called by a javascript onbeforeunload.
Create an Application Process to fire On Demand, named UpdatePageXOnExit or something. In the PL/SQL block of that Application Process, use SQL update commands with the item state of each item on the page that you wish to update; something like the following:
BEGIN
UPDATE table_name SET col1 = :PX_ITEM_1, col2 = :PX_ITEM_2, col3 = :PX_ITEM3, col4 = :PX_ITEM_4, col5 = PX_ITEM_5
WHERE (condition... I would suggest ROWIDs to simplify changes to the
fields of the PK; otherwise you will have to create additional
page items for each field of the PK, then set those items to
the values of the PK when the page loads using a before
header page process, and then use those values in this where
clause like this: where col1 = :PX_ORIGINAL_PK_FIELD_1 AND col2 =
:PX_ORIGINAL_PK_FIELD_2 );
END ;
Go to the page settings for that particular page, and in the JavaScript: Execute On Page Load section, write something like the following:
window.onbeforeunload = updateOnExit;
And in the JavaScript Function and Global Variables Declaration, write something like the following:
function updateOnExit() {
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=UpdatePageXOnExit',&APP_PAGE_ID.);
get.add('PX_ITEM_1',$x('PX_ITEM_1').value)
get.add('PX_ITEM_2',$x('PX_ITEM_2').value)
get.add('PX_ITEM_3',$x('PX_ITEM_3').value)
get.add('PX_ITEM_4',$x('PX_ITEM_4').value)
get.add('PX_ITEM_5',$x('PX_ITEM_5').value)
gReturn = get.get();
get = null;
// Comment out the following line or not, as per the note in the following paragraph
return 'Are you sure you would like to leave the page?';
}
This last piece is the AJAX that updates the session states of the page items on the page that have been changed on the user's end but that haven't been uploaded to the servers end which normally occurs during page submission. Note: If you comment out the return statement, than there will be no warning box that will allow the user to stay on the page. If that is what you prefer, go for it. If you chose to use the warning box, the ajax will execute the page process even if the user chooses to stay on the page.
