Re: Preventing selection event propagation

I have done a workaround in the BeforeSelectionEvent . I'm cancelling
the event at the start of the onBeforeSelection() and then reselecting
the same tab if
the user clicks "Yes" button in the confirmation window.

With this workaround everything seems to be working as expected.

Thanks Ashwin and Jens.
