OBIEE 10g Error from Dashboard layout

We had a requirement where we had hidden two tabs on a dashboard in development. When we requested to migrate dashboard layout to testing environment, we were getting error as below:

Dashboard Display Error
	Assertion failure: pRoot at line 107 of /net/sdchs20n529/vol1/users/anabuild/views/nightly/Tue/101341/RH_Linux/vobs/090414.1900/analytics_web/main/project/webxml/xmldocument.cpp   Error Details (javascript:void(null)) Error Codes: OQ78YWIW

Turns out, we are hitting a OBIEE known bug. When administrator logged in, the error went away, but the dashbaord were not hidden like we had expected. There are two work arounds for this:

1. Hide the tabs manually in Integration/UAT instead of moving the dashboard layout.
2. When moving the layout, try to modify the permissions of dashboard layout object, not sure it will work though.
