Hello, we have come across a cool little problem:
we have a form with a tab panel. A method (onRecordSelection) decides which tab index to show. the two tabs are non-related forms of the same table the tab panel sits on. when switching from record to record via buttons, we get an error.
Now the funny part: the error does not occur when you browse through records using the standard controller instead of a method setting the selectedIndex. the error does not occur either if the tab panel shows the form via a relation (a self-join).
Demo solution attached.
Thanks, Patrick
