Tapestry (occasional) error
Hi!
I'm getting a strange error that only happens occasionally. I have a
form with a number of checkboxes (100) that are beeing procecced. I was not
able to reproduce the problem... I think it happens when there is some time
between the page load and the submit (2-3 minutes... :/ ).
Any clue? Any suggestions? Any addicional information I can give you?
Thanks a lot!

while -- was discussed here:
