I was testing the Woody samples this afternoon with a co-worker (form1 sample, I'm not sure if it was the flow or action version) and received an error that seemed to indicate a double submit problem. That is, I submitted some information, clicked the Back button (or probably skipped back a few pages) and resubmitted, receiving a stack error. We talked about the problem for a while and then I went home thinking I could reproduce it and write up a question about how flow manages state and whether it should prevent double submits. Now, wouldn't you know it, I can't reproduce the problem! I'm using 2.1.2.
it's always best to make sure you use the error (and full stacktrace) at hand to post your questions... it's hard to tell afterwards
now, taking "ockham's razor" as a judge we can only defend the hipothesis that there most probably was no problem ;-)
specially since Cocoon's flow is exceptionally great at handling the double submit case
So, any ideas on how this could have happened? As a company we're looking at using Cocoon as the foundation for a rather substantial forms-heavy web-based application but there are concerns about flow and state-management as well as forms rendering and client-side validation. Any comments that might help relieve lingering fears?
be specific about your fears, and our advise will be worth more
as for the general blabla: you wouldn't be the first one going this path, nbd the combination has been used before in real world apps.
However you can easily spot that while the main vision is solid and guiding a growing user group, some edges have to be smoothened out still and thus things are moving every now and then.
so be prepared for some of that in this part of the playground...
but seriously: if you talk forms-heavy and complex state and flow management, then what alternative is there? ;-)
