Description Andrei Chistiakov 2006-08-28 13:06:16 UTC 
Reproduced in build 060827 (JDK 1.6 beta 2).

To reproduce the bug in column view:

- create a new global element of the boolean type;
- select 'Inherited formn boolean' node and invoke 'Find Usages'.

Comment 1 Nam Nguyen 2006-08-28 22:56:02 UTC 
Refactoring or findUsage does not make semantic sense on inherited nodes,
particularly built-in schema datatype.  In general, user should go to
superdefinition and do refactoring/query there.  

I discussed this with Chris.  The solution for this is remove the refactoring
menu from 'Inherited From' child nodes.  Reassign to Ajit.
Comment 2 bhate 2006-08-29 19:28:03 UTC 
We should not display the refactor action in readonly schema component nodes
(inhertied from)
We should not enable find usages when fobj can not be found, (for primitive types)
Comment 3 Andrei Chistiakov 2006-08-31 13:30:42 UTC 
Verified in build 060831.
