Hmm.. I guess what I don't get is how you can submit a form from a 
DirectLink component. Are you saying to move my form handling to within 
my border component and include it/exclude it based on current page? If 
my tabs all call a listener method via a DirectLink the request will be 
made without the form data included as that would be the same as just 
clicking a link as opposed to submitting a form.

Maybe it would be simpler to just call a javascript method from each tab ie:
<a href="#" onclick="function navigate(1); return false;">Tab 1</a>
... and implement the function on a page by page bases, either delegate 
to the form submit (if there is a form) or just navigate accordingly. 
Problem is that I then have to hack in the href from a PageLink or 
something to get the correct page url.

Or maybe I could send in a form name to the Border component as a 
parameter and if it isn't null, do some form processing .....

There are a thousand 'dirty' ways to do it, I'm hoping there is a 
relatively tidy 'Tapestry' way to do it......

suggestions welcome. paul.

Cool. I would just handle all of it within a listener method. You 
could use
a direct link for your tabs and handle forms based upon which tab you're
currently using. If the content within the tab is defined within your 
page
anyway, you could just tack the listener method on the page and access it
that way.

Let me know if this doesn't help, I'm going to hit the hay right now, but
can look at it first thing in the morning too.

Basically I have a tab structure with 5 tabs, each is an individual
page. The tabs are contained within my border component, the content
with the tab is defined in the page template.

Now 2 of the pages have no form, and 3 of the pages have a form. The
behaviour of the tabs should be that clicking any tab while on a
non-form page simply redirects to the tab's page (ala PageLink) while
clicking the any tab while on a form page should submit/process the
form, then redirect to the tab's page.

That's the long and short of it.
