Hi Steve,
Unfortunately multiple layers are one of the key notions of the application,
and I'm trying to avoid URL scope actions - on the basic principle that it
makes life that much harder for users to break things through being
clueless.
I've been thinking about populating a structure with the relevant details,
and making it persistant in the session scope... But I'm still not sure how
to go about populating the structure based on a link click.
I'm still leaning towards a JS solution... But I keep getting stuck onthe
whole 'but I don't know a damn thing about js, bloody display layer logic
crap'
<a href="javascript:document.testForm.submit();">Submit</a>
<form name="testForm" method="post">
<input type="hidden" name="formInput" value="something">
</form>
The bit I don't know how to do is how to set the value="something" to be
dynamically assigned by JS.
