a4j:support and rich:effect and onchange event

[justinmiller]

I'm have a selectOneMenu that, depending on which item is selected, will display different form controls. It's easy enough to add an a4j:support tag catching the onchange event and reRendering the rest of the form.

I'd like to make it a little more spiffy by adding a BlindUp effect, followed by a BlindDown effect, a la:

<h:selectOneMenu ...>
 <a4j:support event="onchange" reRender="wrapper"
 onsubmit="blindUp({targetId: 'someId'})"
 oncomplete="blindDown({targetId: 'someId'})"/>
</h:selectOneMenu>

<rich:effect name="blindUp" type="BlindUp"/>
<rich:effect name="blindDown" type="BlindDown"/>

<a4j:outputPanel id="wrapper">
 <div id="someId">
 ...
 </div>
</a4j:outputPanel>

This almost works. I don't see the BlindUp effect, but I do see the BlindDown effect. And the selectOneMenu disappears entirely (it appears it's style is being set to 'display: none' and I know I'm not explicitly doing that).

Is there anything wrong with this approach? Is there a better way?

Thanks in advance!
