Re: [Hypercontent-users] Workflow error

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi Carl,
	I've checked in a slight tweak to  
"org.hypercontent.util.GroupMemberAttributes" that should prevent  
this exception from bubbling up, since its occurring during an  
attempt to resolve a user's full name from their ID, which is a nice  
but not critical function for the workflow screen.  However, the  
error indicates that  an event has an empty username associated with  
it, which is highly irregular, so there could be other errors that  
crop up further down the line.  Try the patch and let me know if you  
see any other errors!

Cheers,
Alex
