Comment 2 Milos Kleint 2009-11-03 14:25:28 UTC 
1. project customizer insfrastructure creates a project write mutex for saving the customizer.
2. xam transactions are thread-based, so I have to both start and end transaction on the same thread - AWT one.
3. when saving the xml file, a chain of listeners can eventually kick into the Child mutex.

I'm currently using one long transaction for the customizer which I was told it wrong but there is currently no way to
rollback changes done to the model that would span multiple transaction. only one can be rollbacked within xam as far as
I know.

reassigning to xml.
