How to include Tree and Master Detail in same page - oracle-apex

I am new to Oracle Apex. I am trying to create a 3 column page with 3 regions for tree structure, master detail screen and customized buttons respectively. I was able to create Tree in one page and Master-Detail in different page. When I bring them into one page, tree is not displayed.
When I click on any node of tree I am redirected to master-detail page and data is shown. But I need to display Master-Detail in same page where my tree is present but in a new region instead of redirecting to new page.
SQL Query of tree:
select case
when connect_by_isleaf = 1 then
0
when level = 1 then
1
else
-1
end as status
,level
,name as title
,null as icon
,id as value
,null as tooltip
,'f?p='||:APP_ID||':'||4||':'||:APP_SESSION as link
from (
select to_char(d.DEPARTMENT_ID) id
,to_char(null) parent_id
,d.DEPARTMENT_NAME name
from DEPARTMENTS d
union all
select t.DEPARTMENT_ID || '_' || task_configuration_id
,to_char(t.DEPARTMENT_ID)
,t.TASK_NAME
from TASK_CONFIGURATION t
)
start with parent_id is null
connect by parent_id = prior id
The same query works when creating a tree as new page, but doesn't work when included in Master-Detail page(made 'NULL' as Link in select list). Am I missing any configuration! please help..
Also, any help on creating the 3rd column for including custom buttons region will be a great help.

the problem might be the branch or leave
the answer = is leaf 5 or more
= is branch 5 or more
this the answer might be
when connect_by_isleaf = 5 then
when connect_by_isbranch = 5 then
that might conclude my opininion or suggestion

Oracle Apex Dynamic action not working for form items

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.

Oracle Apex: Auto select if shuttle list contains only a single item

I have a shuttle list that, depending on the selection of a previous form, may have between one and seven items. Is there any way for me to automatically move the entry to the right hand pane if there is only a single selection, just for the sake of long term optimization and user friendliness?
You can add a default Value to your shuttle item
SELECT YOUR_COLUMN_ID
FROM T0000_YOUR_TABLE
WHERE FILTER_COLUMN_ID = :P_FILTER_ITEM_PREV_FORM
GROUP BY YOUR_COLUMN_ID
HAVING COUNT(*) = 1
If there are more than 1 entries for your filter item the statement will return nothing, if there is exactly 1 entry the entry will be returned and set for your shuttle item
I like sim0n's answer. But here's another that uses JavaScript (you can choose which is best for your use case).
Create a Dynamic Action. Set Name to Page loaded and Event to Page Load.
Select the Action created by default. Set Action to Execute JavaScript Code, then enter the following code in Code.
var itemId = 'P1_ITEM_NAME';
var $opts = $('#' + itemId + ' select:eq(0) > option');
if ($opts.length === 1) {
$s(itemId, $opts.val());
}
Don't forget to change the name of the item to match the one on your page.
When the page loads, the JavaScript will check to see how many options are in the select element on the left. If there's just one, it will set the value of the item using the value to the value of the single option.

Oracle Apex - How Show Image in a Dynamic List

I have created dynamic list for sub-menu page,now i want to show image for each list entry
A nice feature is to use Apex Font Awesome icons.
Here's an example of a dynamic list query, based on Scott's DEPT table:
select
null lvl,
dname,
'#' target,
null is_current,
case when deptno = 10 then 'fa-thumbs-o-up'
when deptno = 20 then 'fa-thumbs-o-down'
end icon
from dept
order by deptno
When you add the list to the page (as a region), navigate to its "Attributes" and modify template options by setting the "Display icons" property to "For all items".
Once you run the page, you'll see a thumb up icon by department 10 and thumb down for department 20.
List of all available icons is here.
The answer is in Example 1 in the SQL page of the Create List wizard:
Example 1:
SELECT null,
ENAME label,
null target,
'YES' is_current,
'#APP_IMAGES#del.gif' image, -- <-- HERE
'width="20" height="20"' image_attrib,
ENAME image_alt
FROM emp
ORDER BY ename
first use query like below:
select
1 level,
dname label,
'#' target,
null is_current,
'IMAGE'||img_name image
from dept
order by deptno
with this query img_name set as class for each card. after that use this javascript code on page load:
var spns = document.getElementsByTagName("span");
for (var i = 0; i < spns.length; i++) {
if (spns[i].className.includes('-IMAGE')) {
spns[i].style.backgroundImage = "url(#IMAGE_PREFIX#"+spns[i].className.substring(5)+")";
$('.'+spns[i].className.substring(5)).css("background-size", "cover");
}
}
for this background image url should exist images on ords server.
good luck

How to save and return to newly created item in previous page?

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

Trigger a process (SQL update) when leaving an APEX page

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.
