Well noted is the "data has expired" issue with Flash Forms using Coldfusion. Thanks to this forum I've learned to use the timeout attribute and it happens infrequently now.
I have a different issue with one form however. When I return to it it doesn't show the update to the data. I have to hit refresh in the browser to see my changes.
Resetting timeout to zero expires the form.
Big problem for me. Hope this has a friendly solution.l
