Description

If you open a view with a ListEOPanel and then try to exit the application (which will lead to serialization of the list), a ClassCastException? will be thrown.

Steps to reproduce on a plain unmodified project:
- Start the application and log in
- Go to the admin folder
- Right click Types -> Browse
- Choose "Exit" from the "File"-Menu
- Exception is thrown in background, user cannot close the application until he first closes the types-view

See the attached stacktrace for detailed information:

  • resolution set to fixed.

reproduced error. application contains logic that attempts to implement a feature: desktop save/restore. that is, an attempt to remember and restore the layout of one's desktop. this feature is still a work in progress. anyhow, there was a bug in the implementation as it pertains to a view that shows the lists of types in the system. for now, i fixed this bug by not persisting window information for types listings, which is somewhat of a special case. thanks for catching this.

fix is revision 546 in subversion.
