Sandro Martini commented on PIVOT-694:
--------------------------------------
>This issue has nothing to do with repaint() - it only applies to setListData()
>and clear().
Probably I have not been so clear ... after your fix and my last commits, if
you run Pivot964.java you can see that many components in the test application
have two versions: one with listDataKey/xxxdataKey set and another not, in the
same row.
Clicking the "Clear Data" button you can see that all components with the
xxxDataKey set should have been emptied, but:
- without force a repaint() in (test application) code this is not achieved, so
the question to you:is it right to force a repaint in my code there ? For what
I've been looking in other Pivot sources seems yes ...
- even with forcing a repaint, in some components I don't see the "empty"
content in them, and this is the remaining part to fix for this ticket. Maybe
this is a little "corner case", but I'd prefer to finish fixing it for the
2.0.1, do you agree ?
In my previous comment here I was trying to write a mini-how-to on how to make
this use case work in user applications, could be useful to someone until I'll
move Pivot694* test files in a more useful names, all here.
Bye

> I'm having problems with ListButton.
> When I try to clean a ListButton the last text selected before remains

> I tried listButton.clear() and listButton.getListData().clear(), but with
> none of this I can scape the problem.
> I debugged the application, and the listData of the ListButton is clear after

> Perhaps listButton.setButtonData(null) should be performed in
