IllegalStateException in PageSerializingThread


This looks like a problem. PageSerializingThread definitely does not have a
request cycle going and it's calling getPageMap.  Has it already been fixed
or should I report as a bug?

Re: IllegalStateException in PageSerializingThread

Posted by Johan Compagner <jc...@gmail.com>.

hmmm

now i am really going to make an extra method in Page:
getPageMapName()

because i really start to hate all those:

page.getPageMap().getName()

just to get the name... (and now causing this problem :( )
