Set volatile="true" at the loop component to let the form not to restore the state.
Thanks, DH ----- Original Message ----- From: "Joost Schouten (mailing lists)" <joost...@jsportal.com> To: "Tapestry users" <users@tapestry.apache.org> Sent: Monday, March 09, 2009 6:14 PM Subject: [T5.1.0.0] Loop in Form problem introduced in T5.1.0.0 Hi, I have a loop in a form displaying non form information. An ajax call can update the source of the Loop. When the loop has less, or different items in it during submit then when the form was initiated, the following exception is thrown. Loop.RestoreStateFromStoredClientValue() seems to be causing this problem. My question; Why does the form care about restoring state of a Loop not containing any FormItems? Second, how can I fix this problem? I cannot pull my loop out of the form unfortunately. This seems to be a new problem introduced in 5.1.0.0 as in version 5.0.18 all works fine.
