Description Nico Seessle

2004-05-25 08:59:59 EDT

3.0M9

I can't reproduce this problem, but it occured, when I cut some code, paste it
in another place in the same class and pressed Ctrl+Shift+F to reformat the
code. After the error message the editor went grey and did not repaint. Closing
the editor correctly asked for saving the changes, and the changes were
correctly saved. After reopening the editor formatting does work normally.

I can not reproduce this problem.

Probably this description does not help you very much, but maybe there is a way
to handle the IOOB in a better way.

The exception from comment 2 is covered by bug 57011. The exception from comment
0 is not.

*** Bug 64162 has been marked as a duplicate of this bug. ***

Comment 6 Christof Marti

Duplicate has same stack trace, but happend without formatting. Adapting summary
to reflect this.

The implementation in this area has been rearranged slightly since M9.

Comment 7 Christof Marti

2004-06-16 09:18:48 EDT

PresentationReconciler.processDamage(..) should never have been called. Fix went
into 3.0RC2.

Comment 8 Dani Megert

2004-06-16 14:49:20 EDT

probably not fixed
