Hi Kirk,

What version of Barracuda did you say you were using?  Have you tried 1.2.0
or even the latest CVS?  I think you will find a lot of bugs have been fixed
and some things have been improved.  I would try the upgrade and see if it
fixes any of your issues.  If it does, well, there you go.  Don't need to
worry about those things anymore.

Hi Christian,

Will consider using the custom model approach...
Will report if this works or not.

Thanx

Hmmm...this is quite odd. I wonder if that particular element is actually
getting rendered twice? Might be interesting to stick a debug line in place
and then see if the model is getting called multiple times for the same
element.

Another thing to consider is whether XMLC is somehow mucking with the
structure (that's something of a longshot, since <div>s can be nested).

One other thing to consider...while the approach you've outlined (returning
null to control visibility) _should_ work, I personally prefer a different
approach where you use a custom directive to control visibility. For
instance,

<div id="portlet_CallDesk"
class="Dir::IsVisible.GetPage.p_has_access_calldesk_portal_calldesk">

What this requires you to do is implement the process_Directive method in
your model:

    //process any custom directives
    public boolean processDirective(TemplateDirective td) {
        if (td.getCommand().equals(IS_VISIBLE)) {
            ...return true or false...
        } else {
            return true;
        }
    }

THe advantage of this approach is that if you return false, no nodes below
this are processed (whereas in the approach where you return null or an
invisible component from getItem(), child nodes ARE still processed. So
there are obvious performance advantages in taking this approach.

Let us know if that helps...
