That makes a lot of sense. Presumably if the form failure event occurs there will be no redirect then. My mistake has been performing custom validation in the submit event. Instead I should register errors with the form component. And Russell thanks for the note on validationTrackers, I'll make sure I share any other gotchas I come across. The reason I want to avoid sessions is more based on the environment it will be running in. Multiple load balanced servers with server dropout handling which would mean clustered sessions, something I'd rather avoid. Cheers, Jack
