Description Stefan Röck CLA 2008-10-23 07:40:11 EDT 
Tested with Firefox 3.0.3.

- Load the attached snippet
- Press last button "Select all elements" (sometimes needs two clicks)

The button's selection listener first calls table.selectAll(); and then loads the current selection of the TableViewer via tableViewer.getSelection();

--> Exception:
java.lang.IllegalArgumentException: Index out of bounds

Comment 2 Rüdiger Herrmann CLA 2008-11-27 05:07:12 EST 
The content provider reduces the number if items while in updateElement().
The code in AbstractTableViewer#getVirtualSelection() seems not to be prepared for this.
Can you confirm that this works in RCP?
Comment 3 Stefan Röck CLA 2008-11-28 06:41:55 EST 
This doesn't work in RCP (testet with 3.3 and 3.4) either. Would you consider this to be a bug, anyway?
Comment 4 Rüdiger Herrmann CLA 2008-11-28 07:31:53 EST 
It is rather a question whether the platform team would consider this a bug;) I would go ahead and file a bug against Platform/UI and see what they say.
If you do so, please re-open with a reference to the related platform bug entry.
Comment 5 Stefan Röck CLA 2008-11-28 07:52:15 EST 
filed platform bug 256889
Comment 6 Rüdiger Herrmann CLA 2009-01-22 03:39:44 EST 
Applied the "fix" patch as attached to bug #256889.
