Great that fixed it up :-)
You said you had wrapped the Dialog component just yesterday, but I don't
see it in the tapestry-framework trunk. Is there somewhere I can go and see
how you implemented it?
Oh I have another question... I had to put the .jwc and .script file in the
WEB-INF directory. It seems more standard to keep them in the same location
as the .java file. Do I need to configure something to be able to store
everything in one place?
Anyway, here's the code I used, any suggestions are welcome!

}
@SuppressWarnings("unchecked")

cycle)
{
if(cycle.isRewinding()) {
renderBody(writer, cycle);
return;
}
// configure the node
writer.begin("div");
writer.attribute("id", getIdParameter());
renderInformalParameters(writer, cycle);
renderBody(writer, cycle);
writer.end();
// configure the widget
JSONObject obj = DojoUtils.parseJSONParameter(this, "options");
obj.put("widgetId", getId());
obj.put("toggle", getToggle());
obj.put("toggleDuration", getToggleDuration());
obj.put("bgColor", getBgColor());
obj.put("bgOpacity", getBgOpacity());
// setup script includes

scriptParms.put("id", getIdParameter());
scriptParms.put("props", obj.toString());

getScript().execute(this, cycle, pageRenderSupport, scriptParms);

Without the benefit of knowing what your component code is doing I am going
to guess that you are attempting to render your dialog component during a
Form "rewind" cycle.
The best thing to do in your case is check for cycle.isRewinding() and skip
over all blocks except for renderBody() .

Sorry if this idea seems silly, but this is the first custom
component/dojo
widget wrapper I have made, so it basically just does the same thing as
calling dojo.widget.byId("yourDlgId").show().
My dialog takes a 'shower' and a 'closer' (IComponents) as required
parameters -- I wasn't sure the best way to do this... but I thought it
would allow more flexibility by doing it this way.
My script looks like this: (Dialog.script)
<?xml version="1.0"?>
<!DOCTYPE script PUBLIC
"-//Apache Software Foundation//Tapestry Script Specification 3.0//EN"
"http://jakarta.apache.org/tapestry/dtd/Script_3_0.dtd";>
<script>
<input-symbol key="id" required="yes" />
<input-symbol key="props" required="yes" />
<input-symbol key="closer" required="yes" />
<input-symbol key="shower" required="yes" />
<body>
<unique>
dojo.require("dojo.widget.Dialog");
dojo.require("tapestry.widget.Widget");
</unique>
</body>
<initialization>
tapestry.widget.synchronizeWidgetState("${id}", "dialog",
${props});
dojo.widget.byId("${id}").setCloseControl(dojo.byId("${closer}"));
dojo.widget.byId("${id}").setShowControl(dojo.byId("${shower}"));
</initialization>
</script>
So when I click on my shower (my form submit button) it pops up the dialog
that has the closer (cancel button) and then instantaneously throws the
exception.
It took me a lot longer than 10 minutes to make this (a couple of hours!!)
but after it was done it all seems very simple. I just couldn't find any
documentation anywhere about it, so I just read through some source and
tried putting things together.
When you say "I'm assuming it's not just a simple
dojo.widget.byId("yourDlgId").show()" are you implying that if it is just
doing that, I ought to just use dojo directly in my template?
Thanks,
Peter Beshai
