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,
