Checking the "hide" flag first, and preventing from destroy widget will fix the issue.
Good research. The fix sounds correct.
The question is whether event "cancel" should be called in this situation. It doesn't really cancel a dialog. And the second one, if there are more cases like this in our code.
Widgets may be the only case when we do a cleanup on cancel, because they may be the only case when we create an element before the ok button was clicked.

The patch and test are good. I miss two small things:
- It would be good to close a dialog used in the test.
- Manual TC (for any widget - can be for the embed one so we can confirm that the issue is really gone).

Fixed with git:24d1c51.
Note: See
TracTickets for help on using
tickets.
The problem exist in components which listen to "cancel" events on dialog. They simply ignore "hide" flag which is passed in event data.
This property is set in dialog plugin - based on confirm popup which shows to user when there are some changes in dialog. See here.
Here is a listener which lead to error. It destroy widget, although dialog is not closed.
Checking the "hide" flag first, and preventing from destroy widget will fix the issue.
The question is whether event "cancel" should be called in this situation. It doesn't really cancel a dialog. And the second one, if there are more cases like this in our code.
