Hi Lasitha, Your thoughts do require some thinking, I'm doing a site now that is not so critical in the consistency of the data, as it's merely a simple membership database, but if this is to replace a c/s biz application, this will be a issue, is the current Tapestry - hibernate ready for that? what we need to do in that kind of situation? I asked last time but it was considered a hibernate issue, I like to hear from others too how they manage situations like this? thanks.
