Hello!
We just discovered a strange behaviour containing modal dialogs called from
an frame which differs between ULC version 6.0.4 and 6.1.1.
The following describes the starting situation: We have a frame which
listens to window action within a windowlistener. When trying to close the
frame, the listener fires up a dialog which mimics an ULCAlert showing some
confirm message (e.g. "Save changes?").
After clicking to confirm, the dialog has to close the parent window. If I
am not wrong, normally the dialog will disappear with the parent. Now, when
we fire up the frame again for ULC 6.1.1, without restarting the
application, the dialog is still shown. After confirming it again and
starting the frame for the third time it is finally invisible. In ULC
version 6.0.4 that behaviour doesn´t come up. The dialog will be correctly
closed and doesn´t come up after restarting the frame.
I have attached a simple snipped. If you run this code as described above
under 6.1.1 and 6.0.4 you will see the difference.
We will be glad, if you have any hint or idea to solve this problem.
Best regards,
Daniel
