illogical state...
-----------------------------------------------------------------------------------------
Key: MYFACES-690
URL: http://issues.apache.org/jira/browse/MYFACES-690
Project: MyFaces
Type: Bug
Components: Tomahawk
Versions: 1.1.0
Environment: http://www.irian.at/myfaces/tree2.jsf
Reporter: Erik Mellegård
Server side toggle tree2 example throws exception.
To reproduce the error:
1. Open http://www.irian.at/myfaces/tree2.jsf
2. Expand "Inbox" and "Frank Foo" folders
3. Click on the line that attaches Frank Foo with Requires Foo (where there
would have been a plus if Requires Foo would have contained children)
This generates the following exception:
type Exception report
message
description The server encountered an internal error () that prevented it from
fulfilling this request.
