A lot of investigation later: Seems this time I have a really big problem with this. I have a new component which is very similar to the ones I already had (did not find any convincing difference until now), but it does not work. The new component has a @Create @Begin method to begin the conversation, just like all of my other components. It is @Conversational, just like all of my other components. And it is called from rich:dropdownmenu with conversationPropagation=none or end, I tried both, just like all of my other components. But I get the annoying "Begin method invoked from a long-running conversation" error. Now I tried to use join=true (not that I wanted to do this, but only to look what will happen), and the result is very impressive: "no long-running conversation for @Conversational bean" I've tried to debug all this. Set a breakpoint at Manager.setLongRunningConversation. But this was a dead end. Conversations are turned on-off-on-off just during one single Event (and sometimes just on-off-on, that's the problem), which gave me absolutely no clue. Please help me!!!
