Input Help not populating value

Question

We are facing some issue with Interactive Adobe form embedded in an ABAP Web Dynpro application.
We have designed an interactive form with provision for input value help. For showing value help on the form we have used u2018Value Helpu2019 button from Web Dynpro Native Tab in the Adobe Designer.
We face the issue when a user clicks on the value help button (any field). System takes care of showing the input values in a popup when a value help button is clicked. User is able to select a value but the selected value does not populate in the corresponding field. There is a standard Javascript written behind these Value help buttons which populate selected value from the popup in the corresponding fields.

Dear customer,
I was trying to replicate the issue, but it seems that the sap server
is currently down.
Therefore I was checking the coding of your webdynpro application.
Problem is the following:
When the popup is called the first time, the ALV component controller
gets initialized and is doing things like setting up component usages
for the F4 help.
When you close the popup, the WebDynpro framework is closing the view
containing the ALV, but the ALV component controller stays alive.
Next time the popup is called, the ALV component controller does not
get initialized, since it is still alive.
This results in the fact that certain information is not available
the second time you call the popup, since the initialization did not
take place.
Solution:
When the popup is closed you have to explicitely delete the embedded
ALV component. This is not only important to have the OVS problem
solved, but in addition a proper cleanup is done.
Please add coding like the following to your WDDOEXIT method of view
POPUP_V:
L_REF_CMP_USAGE = WD_THIS->WD_CPUSE_POPUP_ALV( ).
IF L_REF_CMP_USAGE->HAS_ACTIVE_COMPONENT( ) IS NOT INITIAL.
L_REF_CMP_USAGE->DELETE_COMPONENT( ).
ENDIF.
