I had thought there would be some funniness with a conversation-scoped component starting its own conversation, so I moved beginEdit() to its own class (better design anyway) and edited pages.xml accordingly
| @Name("contactAction")
| public class ContactAction {
|
| @Logger
| private Log log;
|
| @Begin
| public String beginEdit() {
| log.info("Conversation begun by beginEdit()");
| return null;
| }
| }
|
Still no luck, same behavior. As for a conversation, I know beginEdit() is getting called (I see the log message) but I guess no conversation is entered after all, since there's no conversationId parameter in the URL when I edit, and the debug page shows no active conversations. I wish I knew why that was.
I do see a conversationId after I click update, which is when I should expect to see the conversation ended! The debug page does show there's no active conversations after update, however.
I get the traceback all the same. Here's the whole thing:
