Thanks for the jira issue. Sorry I've been really busy trying to get some normal contact stuff completed.

I've figured out why the exception is being thrown: my formSubmit method requires the submission control (Submit or LinkSubmit) to have set the tag and selected attributes/parameters. Now, my async button comes in without those set and the null pointer is thrown. So I've added an "if null return" block and the dialog appears as required, but ... ... that still doesn't explain why the autoSubmit parameter in the Annotation isn't stopping formSubmit from being called. I've also tried with a Submit component and a LinkSubmit using attributes in the markup to define the listener etc, still the form submit listener is called. So, could the issue be that autoSubmit attribute does not work? Seems like my only option (besides living with it for now) is to use a DirectLink which works fine as it's not associated with a form .. so I'll have to figure out how to style that like a button, or emulate it's behaviour in a button. Jesse, I've logged an issue in Jira for you. https://issues.apache.org/jira/browse/TAPESTRY-1630 Thanks, Paul.
