I try to set the value of a popup lov with a dynamic action "Set value" of type PL/SQL Function Body. This works with a select list, but not with a popup lov. How can this be done?
Let's assume your item is P1_ITEM and your LOV is
select display, return from table;
In standard Select List value is stored in #P1_ITEM.
In Popup LOV value is stored in #P1_ITEM_HIDDENVALUE, but displayed in #P1_ITEM.
So in dynamic action, you need to set two actions:
Set value 'return' from LOV with affected item P1_ITEM.
Execute JavaScript code
$("#P1_ITEM").val(display)
$('#P1_ITEM').val(&display.)
where display is the name of the field in SQL.
Hope it works.

I have a Select list filter on the top of the page. I want its return value to get into any column which I create in IG report automatic DML process.
Suppose, Select list has a value "Step", when I add a row in IG report, that value should be saved into DB for one column which is hidden on UI.
I tried but sometimes it stores the value which I selected in Select list item as my last selection not the current one. Do I need to create Application item for this? Please help. TIA
In this case there is a table ig_tickes with a status column. On the page there is a page item P131_STATUS (select list) with values "OPEN" and "CLOSED". There is an interactive grid on table ig_tickets with column STATUS hidden. Functionality is that user selects a value from the select list and then clicks "Add Row".
Give the interactive grid a static id of "tickets"
Create a dynamic action on change of P131_STATUS with a true action of type "execute javascript code" and code:
var model = apex.region("tickets").call("getViews").grid.model;
model.getOption("fields").STATUS.defaultValue = apex.item( "P131_STATUS" ).getValue();
That's all there is to it.
I'm trying to create lov in which once the machine is started it should not show in popup lov after submit.
Popup lov sql is as below:
select machineid,machinenm from machinemaster where idlemachine = 'Y';
but the issue is once machine is status change and this query not finding result for the perticular machineid so in lov it shows blank.
Please suggest any workaroud.
First of all, query you posted looks wrong. Generally speaking, list of values' query returns two values in the following order:
display value
return value
We usually display names and return IDs, which means that you'd probably want to use
select machinenm as display_value,
machineid as return_value
from machinemaster
where idlemachine = 'Y';
the issue is once machine is status change ...
How is that statement reflected in query you posted? There's no "status" column nor "change" status itself; where clause says where idlemachine = 'Y' - no status, no "change".
... and this query not finding result for the perticular machineid so in lov it shows blank
I believe that you should set the Display extra values property ON. Help says:
An item may have a session state value which does not occur in the given list of values definition. Select whether this list of values displays this extra session state value. If you choose to not display this extra session state value and there is no matching value in the list of values definition, the first value in the list of values is the selected and displayed value.
If you're seeing the NULL value, it means that you actually set
display extra values to OFF
display null value to ON
I understand that the default behavior of LOVs is the following:
SELECT business_desc as display_val,
business_id as return_val
FROM businesses
This attached to a select type page item P1_BUSINESS will display a list and when a list row is selected, then assign the business_id value to the page item P1_BUSINESS.
Is there a way to build a list of values to set the value of more than one page item that are not displayed? Using the below SQL:
SELECT business_desc as display_val,
business_id as return_val,
form_type,
individual_flag
FROM businesses
Where now when a user selects something from P1_BUSINESS it sets the values of that row/record as follows:
P1_BUSINESS = business_id (like it does by default)
P1_FORM_TYPE = form_type (P1_FORM_TYPE is a hidden page item)
P1_IND_FLAG = individual_flag (P1_IND_FLAG is a hidden page item)
I know I can do this with an onchange dynamic action, but just curious if can do inside the LOV or select page item (P1_BUSINESS) declaratively.
In Shared Components > List Of Values, there is an attribute "Additional Display Columns". The help text on that screen says it all Additional display columns can be defined for item types that support multiple display columns, for example the Popup LOV. For item types that do not support multiple columns, these will be ignored. If adding additional display columns ensure that the return column is included in the column list. The return column can be set to Visible No and Searchable No if you do not want it displayed to users.
Example using emp/dept sample data:
Create a list of values on table emp with return empno and display ename. Save.
Edit the LOV and click Additional Display Columns > Select Columns. Select job as additional column.
In the IG, set Visible and Searchable to "No" and Apply Changes.
On the page, create 2 page items: P1_EMPNO (type popup LOV) and P1_JOB (type Text Field)
For P1_EMPNO, pick the LOV created above as shared component > List Of Values and add JOB:P2_JOB under Settings > Additional Output. JOB is the additional column name/alias and P2_JOB is the item it should map to.
Now when you run the page, observe that P1_JOB is populated when you select a value for P1_EMPNO
This is a VERY basic question. Sorry for not providing any code I have NO IDEA how to even start tackling the problem
I have lets say two fields... One is a date selector field and the other a regular text field. What I want is when I select a date (or type a date), the value comes in the second field... Just that...
I'm on APEX 5.1.4
Since you have stated that the second item is a text field, you could do this with the help of a dynamic action that sets the value of the second item when there is a change in the value of the first item ( date field).
The following would be the steps, if you are using component view:
Create Dynamic Action
When
Event : Change
Selection : Item(s)
Item : First Page Item
Condition : is not null
True Action
Action : Set Value
Fire on Page Load: No
Set Type: You can choose how you want to set the value of the second item on the page.
If you have the flexibility to change the second item to be a select list and you have a list of values that goes with a date, you could do this much simpler, with a Cascading LOV
On Second Item's - Under List of Values section
Cascading LOV Parent Item(s) : First Item
Page Items to Submit: First Item
List of Values definition: Here you can define the query.
Hope this helps.
There are a few different ways to do this, probably the easiest way is as follows.
Assume your two items are P1_ITEM1 and P1_ITEM2.
Create a dynamic action which fires on change of item P1_ITEM1.
The true action of this should be action:set value, set type:PL/SQL Expression, item::P1_ITEM2, items to submit P1_ITEM1.
I have an APEX page where it contains multiple regions. Each region has its own drop down list (Select list) item and a bar chart. My problem is from any particular region when I select a value from the drop down list, the whole page is refreshed as I have the option Submit page set for Page Action on Selection property.
How do I perform partial refresh so that during the selection from drop down list only the bar chart for that region should be refresh and not the entire page?
Go on your select list item and change the Page Action on Selection property from Submit Page to None. Then create a dynamic action on page with the following options:
Event=Change
Selected Type=Items
Item=Your select list item
Action=Refresh
Selection Type=Region
Region=Your bar chart
Same as answer above with one trick to make it work. The value in your select list has not been submitted so will be null and not work.
Add another Dynamic action that runs before the refresh one of type PLSQL. set the code to null; then add your select list to the "items to submit".
Should work now :)
