Guy Coleman commented on MYFACES-1550:
--------------------------------------

I've seen this after upgrading from 1.1.3 to 1.1.5. It happens when an action method returns null.

> Pages that once worked (1.1.5) stopped working for some reason (within the past week).  The issue seems to be with generated id's on components.
> You will see this where you load a page and then reload the same page through a hyperlink or rendering for the second time.
> There seems to be some correlation with the <f:facet tag.  I have a page with a <t:dataTable and several columns that use the <f:facet> tag to provide the column header.  The page loads just fine initially but if I reload, I get a blank screen and the following message in my Tomcat log file.
> If I remove the column header and the facet tag, I do not see the error.  About a week ago there were no problems with this page so it is something new that has been introduced and should be fixed.
