Description
The Forums tool is not working properly when posting messages. Sometimes a message is created, but Sakai does not render it until the Forums tool is reset. Sometimes it causes a stacktrace with a nullpointerexception.
To test:
- Go to the Forums tool in a course.
- Go to a topic screen
- Click "Start a New Conversation" or Reply to an existing message
- Type a message and click "Post"
I haven't determined the exact circumstances that lead to a bug report page vs. Sakai rendering a blank Topic page, but it never behaves as it should. I think even when it is showing a page, it is still logging a stacktrace to the log.
Two stack-traces I've seen generated.
