Error on CADDoc content tab

[avillanueva]

Users just starting reporting this error message on the content tab for CAD docs. I checked and this class does exist in the wncWeb.jar file and that file does exist. As far as I know, nothing has changed to system and we've been operating normally for 6 days.

An exception occured while processing the request.

 Opened a ticket but at a loss since I think error message is not accurate.

File this in the duh category. When applying UI customizations (regardless of how minor), clear and rebuild tomcat cache.

Yep. Doing that and others in my windchill startup sh script:

• rm -rf /opt/ptc/Windchill/Windchill/tomcat/instances/* 2>/dev/null
• rm -rf /opt/ptc/Windchill/Windchill/tasks/codebase/com/infoengine/compiledTasks/* 2>/dev/null
• rm -rf /opt/ptc/Windchill/Windchill/codebase/wt/workflow/expr/* 2>/dev/null
