Visible context menu on CLOSE causes crash

SRPSupport · October 2012

Hi all

This isn't an urgent one as its not terribly likely, but your help would be appreciated as always

A form has 2 buttons called BTN_TEST_CLOSE and BTN_TEST_CM. Below is the commuter - you will want to change the CLICK event to 'OnClick' for testing.

A cancel button is set in the create and also a context menu. If I run the form and press BTN_TEST_CM (to display the context menu) then with it still visible press ESC the form closes -> OI 9.3.1 crashes. It's only when pressing ESC that this happens, closing by any other way as a standalone form or a dialog all works fine.

At a guess the context menu component might not be being destroyed with the button perhaps?

Other scenarios I tried:
1. use post_event - this closes the window without a crash, however the contextmenu is still visible. Also post_event is not an option when using dialogs in a workflow heirarchy.
2. return 0 instead of 1 from commuter. Same as 1, except OI will crash after you click on a menu item.

Hope this helps, please let me know if you need anymore info.

compile function jb_test_events(focus, event, param1, param2, param3, param4, param5, param6, param7, param8, param9, param10, param11, param12, param13, param14, param15)

* system
$Insert logical
declare function get_property
declare subroutine set_property, send_message, send_event

valid = true$
window = field(focus,'.',1)
control = field(focus,'.',2)

begin case
	// form-based events
	case control = ''
		begin case
			case event = 'CREATE'
				gosub create
		end case
	// control based events
	case control = 'BTN_TEST_CLOSE'
		if event = 'CLICK' then
			send_event(window, 'CLOSE')
		end
end case

return valid
** eof *****

create:
	set_property(window:'.BTN_TEST_CM', 'OLE.ContextMenu', 'test':@fm:'test2')
	Set_Property(window:'.BTN_TEST_CLOSE', 'OLE.Cancel', true$)
	return

Thanks for catching this and providing such a thorough explanation. It shouldn't be too hard to fix. I'll let you know when it's available.
