When I throw any exception in a conversation started with FlushModeType.MANUAL, I get redirected as defined in pages.xml:
<message>This message should always be displayed!</message>
but the message isn't displayed in <h:messages>. Also, according to debug page, the conversation seems not to be ended despite use of <end-conversation>. Is there a way to fix this? I'm using Seam 2.0.1.GA.
