Hi Tuomo, I've had a quick look - seems good. I only do struts part time so I can't really keep up with you, which is a shame. I'll try to use your code - if you'd like to post it here or mail latest version(s).
Someone is working on a workflow component for struts, which I think is the same job as this. See http://jakarta.apache.org/struts/proposal-workflow.html I guess this project won't be finished for ages - so is no use to us! I prefer just 1 returnStamp at a time - lighter load on server & simpler to program - anything that sets up a return stamp deletes whatever is already there. Maybe you would need multiple returnStamps for when the user opens a second browser & runs the same app. keep up the good work! Keith. --- Tuomo Syv�nper� <[EMAIL PROTECTED]> wrote: > Sorry..
