NoSuchElementException in volatile loop
Sorry, this time with stacktrace...
I have a form which causes the following exception on submit.
This seems to be a problem with the advance_volatile commands in the form.
I am using tapestry 5.0.18. Any ideas how to fix this?
Stack trace below,
Thanks for the help.

Re: NoSuchElementException in volatile loop
Posted by Joachim Van der Auwera <jo...@progs.be>.
Problem solved.
It seems that for some reason not entirely clear to me, there was a
difference in server side and client side state. The end result is the
exception below. I believe that either there is a mistake in the
comments in the code (about everything being driven by the stored
actions, in which case a NoSuchElementException should not occur) or
that a better exception message could be produced indicating that the
number of items in the loop does not match the count expected by the
stored actions.
Kind regards,
Joachim
