[Chameleon] Dynamic Template Changes

[Paul Spencer]

Steven,

this should be relatively simple, it is the same mechanism that is used 
by the ability to bilingualize the application ... your button needs to 
call a javascript function that simply sets the form variable TEMPLATE 
to the new value you want and then submits the page.

<script ...>
function switchTemplates()
{
   document.forms[0].TEMPLATE.value = "http://path-to-new-template.html";
   document.forms[0].submit();
}
</script>

If you need to go to different templates, I would modify this so that 
the URL of the template is passed to this function :)

Cheers,

Paul
