The rendering context XHTML document is nil on page refresh

Hi,
sometimes, when I hit the refresh button of my web browser, I get the following stack trace from Seaside. It seems the WARenderingContext has a document which is nil. I'm using pharo1.0beta-10401web09.07.5.image which contains Seaside 2.8a1-pmm.593. Can somebody help me please?

Can you show GdoHeader>>renderContentOn: ?
Can you define "sometimes"? Do you mean certain pages do it and certain pages don't or, on any given page, sometimes it happens and sometimes not?

if i remember correctly this might have something to do with ajax callbacks but i just can't remember the details. The RenderContext's document is nil, probably because it was released. Maybe that info helps. Karsten Damien Cassou wrote: Hi Julian, On Mon, Aug 3, 2009 at 3:04 AM, Julian Fitzell[hidden email] wrote: --

In reply to this post by Damien Cassou-3
Hi Damien,
I don't see an obvious problem, I'm afraid. As Karsten mentions, a RequestContext has its variables nil'ed out when it is finished and its response is returned, and that's the most likely cause of the document being nil, but I certainly don't see anything in the code you posted that would explain that. Usually that is caused by somebody storing the canvas and using it again in another request (like, an ajax rendering callback). So make sure you're not storing the canvas or request context anywhere and that any ajax callbacks are using the rendering that is passed to the block, and not the one in the rendering method (Slime checks for the latter). If neither of those is your problem, try stripping your code down to the simplest example that demonstrates the problem and someone will take a look at it.
