Description Nathan Fiedler 2006-09-07 02:28:45 UTC 
Related to issue 84219, open the massive OTA schema and an empty schema. Cut all
of the complex types from OTA and paste them to the empty schema. After several
seconds, an NPE will occur, soon followed by another, and another, and so on.

It seems that because the PasteAction.ActionPT is running the paste in a
RequestProcessor thread, the AWT thread is competing to update the interface
while the models are still changing. Would be good if we could force the paste
to happen on the AWT thread. The alternative is to harden the schema/ui code to
deal with components that are no longer a part of a model.

Should test with elements, attributes, and the other schema component types.

The schema/ui code has been made more tolerant of model changes.
