What do you mean by "if any are set to execute?" I admit that I am
relatively new to using PWC and there is probably something I need to
do that will seem obvious once I understand it.

The sample code is awesome. In fact, I may be guilty of not reading
the docs as carefully as I should because the examples make it so easy
to learn by example. To make this concrete, here is the code DIV I use
to do Dialog creation with AJAX loaded content:
<div style="display:none" id="open_feedback_codediv">
<xmp id="open_feedback">
Dialog.confirm({url: "/components/feedback.jsp", options:
{method: 'get'}},
{windowParameters: {className: "kdialog", width:600,
height:350, zIndex: 1500, resizable:false, recenterAuto:false, title:
"Krillion Feedback...", showEffect:Effect.BlindDown, hideEffect:
Effect.Fade, draggable:true}, okLabel: "Send",
buttonClass: "myButtonClass",
id: "myDialogId",
cancel:function(win) {},
ok:function(win)
{sendFeedback(document.getElementById('feedForm'));
window.setTimeout(Dialog.okTimeout,1500)}
});
</xmp>
</div>
The normal way in a regular HTML request response to get the round
corner effect is to make a NiftyLoad() javascript function call either
with the onLoad event handler for the page or by placing this
javascript call at the end of the BODY element of the response:
<script type="text/javascript">NiftyLoad();</script>
Neither approach works with my feedback.jsp response. I didn't expect
the onLoad event handler to work for an XHR, but, I had hoped placing
the call explicitly at the end of the feedback.jsp contents would. I
have since read on this mailing list that javascript specified in the
AJAX content loaded into the dialog will execute as a result of event
association with elements in the content when those elements are
clicked, but, inline script calls like the one above are not going to
be executed.
Although I am fairly new to AJAX, I do know how to register an event
handler for when the call returns. In this case, the libraries are
making the AJAX request. Not me. So, I haven't figured out how to
register my own event handler for when the XHR completes for the AJAX
content loaded into the Dialog PWC object.
As a workaround, I had used a setTimeout() call in my code DIV
javascript right after the call to Dialog.confirm() to make the
NiftyLoad() call after a specified delay. Of course, this is a hack
and I'm sure there is a more elegant way for me to do this. Plus, the
designer (and I agree with him) doesn't like the fact that there is a
delay where the dialog content first displays and then the corners get
rounded after the timeout interval. I must use a conservatively large
timeout to allow for variable time for response from server.

I'll go back and review the docs carefully again for information on
how to set scripts to execute upon completion of the loading of my
AJAX content into the dialog. I still don't understand how to do that
in a way that ties it to the XHR completion for my AJAX content.
