We have a large Seam application based on Seam 2.0.1GA running in JBoss 4.2.0GA. For the most part it is a very robust application but we have one area which has caused us nightmares.
In some instances we were getting what looks like mulitple / duplicate form submits. However, they sometimes came minutes apart. After some serious testing we came to the conclusion that what was causing this was there was an
a4j call executing at the same time as the actual form post was occurring. This causes screen navigation to mess up to the point where the screen is redisplayed with the same data that just got submitted ( allowing the user to resubmit / duplicate the last submit ). In the normal flow, the conversation would be ended and the screen redisplayed with empty fields. It looks like pages.xml is not honored in this case???
Anyway, has anyone seen this issue and if so, is there a solution?
