    When you expand a node with ServerSideCallback it works the first times. But if I refresh the page and try to expand the node once more, it hangs forever. Clicking it mulitple times just adds the loading symbol several times. This only happens in Firefox. I've tried both FF 3.0 and 3.5 and have the same problem.

    I've managed to reproduce this on the demo pages as well.

    Check this screenshot too see the problem.

    Anyone have an idea where to start searching for a solution?

    Regards

    Hello Oyvind Andersen,

    Unfortunately, this is an issue of Firefox - reloading the page does not reload it 'properly'. In this case, after reloading the ViewState hidden field still has its old value and when the browser sends it to the server-side an "invalid state" exception is thrown. You can test this by reloading with Ctrl+F5 in Firefox - this does a much 'cleaner' reload and does not have the described issue.
