a4j:repeat - row is unavailable

[dustismo]

Hi,

I have a page using a:repeat to iterate over a model (it is a seam-gen (from cvs) page).. It worked fine. I haven't touched that page, nor the model or anything affecting that page.. Now it doesn't work, nor does any page that has a:repeat in it. they all throw the same exception:

ERROR [STDERR] Mar 21, 2007 12:05:25 PM com.sun.facelets.FaceletViewHandler handleRenderException
