Should I log this in Jira Jesse?

Thanks Jesse,

I've changed it to
@EventListener(targets = {"myButton"}, events = "onclick", async = true, autoSubmit = false) 
   public void showMyDialog()
and the same exception is thrown. Any more info?

Paul.

Components implementing IFormComponent that are targeted with an
@EventListener do now have their surrounding forms submitted automatically 
as part of the async request.  If there is something in your logic that
doesn't need/want this to happen you can set the autoSubmit = false
parameter in the annotation and it will do the pure async request only
without the form submission.

Hi,

I've upgraded to 4.1.2 from 4.1.1 and am getting the following when I
try to load one of my Dojo Dialogs (async).

It seems tapestry is trying to call getPage with a null page name, but
I'm not sure why formSubmit is being called at all (unless it's part of
a rewind?)

The trigger is being defined like so:
    <input type="button" jwcid="[EMAIL PROTECTED]" label="show dialog"/>

The listener being called is defined like so:
    @EventListener(targets = {"myButton"}, events = "onclick", async =
true)
    public void showMyDialog()

If i click my button i get the following exception wrapped in a error
dialog  (async):

Failure invoking listener method 'public org.apache.tapestry.IPage
MyPage.formSubmit()' on [EMAIL PROTECTED]: Parameter name must not 
be null.
