Title: cmd_str$="End" not working in object nomads issue
Post by: Peter.Higgins on December 18, 2020, 01:26:13 PM

Occasionally I see this issue and cannot remember how it was solved. 

Issue:

On a new object nomads Dialogue panel copied from a template panel and modified, the Cmd_Str$="End" will run the ON_EXIT and ON_DELETE logic, but the panel hangs there active.  Using a tested program structure template so both procedures have return values of 1.  Using Developer package windx to connect to a Centos system.   Using a bunch of objects but moving them around between on_delete and on_exit makes no difference.  Putting an extra Cmd_Str$="End" in the on_exit does nothing either. 

I think the solution last time was to delete the nomads entry and re-create the panel.   
This panel is very large and complex to reenter manually.

Any ideas why this is happening?
After exporting and reimporting and still no joy, I realized the template had lost the local return flags so ON_EXIT and ON_DELETE were returning 0.   :-[

The method for Nomads Objects that is called when the user or application request closure of the panel is OnExit() (not On_Exit as posted in your message).

This method can return 0 if the close is not to occur or 1 if you want the closure to happen.
