Channa Gunawardena commented on MASHUP-968:
-------------------------------------------
Added null check for userId in getUserProfile - SVN 19427.
General approach on all pages is to getRegistry, which provides an instance for
'anonymous' if userRegistry is null. Need to find situations where this
failsafe would not come into play and correct.
> Exception when navigating to mashup.jsp page (or others) after hours of idle.
