Does anybody see anything obvious in this stack trace? I used to
have this exception ages ago and it was obscure. I don't recall
what ended up fixing it exactly but now that I moved my application
to Wonder I'm running into this again and haven't figured out yet
why or how to fix it. Any ideas?? Pleeeassee!! :-)
I have seen this before. It is caused by the context not knowing the
current component. This is hitting some action method. What is it
returning?
