Re: PageRenderSupport problem (Body component is in template)

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,

So what does it do after loading up? I'm assuming it's not just a simple
dojo.widget.byId("yourDlgId").show() ?

I created the same component in 4.1.1 yesterday btw. (Took me all of ten
minutes!, of course that is expected..)

Hi,

I have created a wrapper for the dojo component Dialog and it works fine
(in
general!), but I have a problem when I use it with my form. I want to have
the dialog appear when I submit the form (ie, the form submit button is
the
show controller) and the dialog will basically have a cancel button (close
controller and Submit component with type cancel).

The dialog loads fine, but soon after loading it throws an exception:
Component FileUpload/uploadingDialog requires rendering support, but no
PageRenderSupport object has been stored into the request cycle. This
object
is typically provided by a Body component. You should add a Body component
to your template.

I do have a body component defined : <body jwcid="[EMAIL PROTECTED]">.

Any ideas how to fix this problem?

FYI in my Dialog.java file I have in the renderComponent function:
PageRenderSupport pageRenderSupport =
TapestryUtils.getPageRenderSupport(cycle, this);
getScript().execute(this, cycle, pageRenderSupport, scriptParms);
