[Building Sakai] EntityCustomAction problems

[Adrian Fish]

Hi Stephen,

Thanks for the info. I think I'll just give up on hacking the EB stuff; 
I was hoping to have the basic things like delete and create a room so I 
could demo here, without hassling you. I'm going to package up the 
floating chat code and attach it to the JIRA this afternoon so people 
can kick it about.

Cheers,

Adrian.
