Re: How do I find what was selected from a poplist?

Solved my problem.

It seems that the problem was really with repopulation of the item (poplist).
While deleting the old record group, creating a new one & populating the poplist showed the correct values, it left the list's "default" selection at the first non-null value.

In other words, if the user selected the first item from the drop-down and then made a change that caused the drop-down to be repopulated with different values, the new value shown by default was the first non-null value.

So, if the user wanted that value and clicked the OK button (which had a when-clicked to take the value from the poplist & assign it to another variable), the poplist didn't think the selection had changed.

I was able to fix the problem by setting the poplist item to null PRIOR to repopulating with a new record group. When in doubt, initialize! :

   :REASON_BLOCK.NAME := NULL;    populate_list('REASON_BLOCK.NAME',vReasonGroup);

• end of code ---

Setting :REASON_BLOCK.NAME to NULL did the trick.

Thanks to the few folks who attempted to help me via email.
