Description Benno Baumgartner

2005-09-08 11:52:08 EDT

Build id: I20050906-1200

After applaying an `extract to local variable' quick fix and a following undo
operation I've got the following exceptions and the code in the editor was only
partly shown (see screenshot). I could not reproduce it.

We've changed code in ProjectionDocument.
Tom, can you please investigate.

Investigating

Comment 4 Tom Hofmann

2005-09-09 06:03:27 EDT

Hm, the IAE signals an internal problem of ProjectionDocument stemming from either

- an bug in ProjectionDocument or ProjectionMapping
- a concurrent modification between
ProjectionDocument.computeFirstUnprojectedMasterRegion and
ProjectionDocument.internalAddMasterDocumentRange

The recent change to ProjectionViewer may have revealed this, but is not the
source of the problem.

Lowering the priority again until we have steps.
