I have the same error in the version 1.2.1GA. Is this me or is this due to an error of versionning : "" I currently study JBoss Seam 1.2.1GA in order to use it soon for an application in production. I created a conversation based on a pageflow. The conversation proceeds perfectly. I can start and use at the same time several instance of this conversation by using the functionality of workspace management. Here's my problem: When I switch from one conversation to another, all functions well. However, when I finish one of the conversations, the second pageflow does not function any more (I can only destroy it thanks to the workspace manager). I tried to use different manner of starting and finishing the conversation (via a page or an action). I thought that that could be with a mechanism of hierarchy of the conversations but when I added nested=false to the @Begin, nothing changed. I like the framework much and I would like to use it for a customer. I thank you very much for any help !
