Begin conversation on null return (not currently possible -

[antispart]

Currently,

If I have a method:

@Begin
public String startConversation() {
 return null;
}

When this method is called a conversation is not started. If I change the method to return non-null:

@Begin
public String startConversation() {
 return "thispage";
}

Then it works.

This poses a problem for A4J where I want to return non-null so that only certain portions of the view are re-rendered.

It would be great if it were possible to start a new conversation in this way - Would be more ajax4java friendly.

Read the JavaDoc for @Begin. A null outcome is special.

The solution to your problem is to declare the method void.
