The exception really doesn't tell me much, but from what you said, it might
be some problem related to concurrent execution. I had something similar
happen. The page the user was loading generated multiple requests to the
same application through the same session. Because of the way it was
implemented, it just couldn't handle the multiple simultaneous requests.
So I implemented a WebRequestServiceFilter that makes sure requests coming
from the same user are executed sequentially. Something like this:
public void service(WebRequest request, WebResponse response,
WebRequestServicer servicer) throws IOException {
if (request.getSession(true).getAttribute("synchronizeObject") == null) {
request.getSession(true).setAttribute("synchronizeObject", new Object());
}
synchronized (request.getSession(true).getAttribute("synchronizeObject")) {
servicer.service(request, response);
}
}
I don't know if it would solve it for you, but you could try it.

Subject: intermittent Runtime exception
I'm seeing an exception page that only happens if i hit reload multiple
times in succession very quickly - the page looks fine otherwise. I'm
running tapestry 4.0.1 on solaris, jdk 1.5.0_06. Any ideas?
