Hi, (sorry for crossposting, I posted in Richfaces forum, should have used this forum)

I am trying to create a component to add a onchange listener (a4jsupport) to all UIInput components on a page.
This is comparable to the 'validateAll' tag in Seam.
Like this:

 <t:supportAll event='onchange' action="#{myBean.action}">
 <h:inputText ....>
 <h:inputText ....>
 </t:supportAll>

I tried subclassing HtmlAjaxSupport, but this stops the children from rendering.

In my component, I add a HtmlAjaxSupport element to all subclasses of UIInput:

 HtmlAjaxSupport support = new HtmlAjaxSupport();
 support.setEvent("onchange");
 support.setReRender(rerender);
 for (ActionListener l : this.actionListeners) {
 support.addActionListener(l);
 }
 c.getFacets().put("a4jsupport", support);

I see the onChange in the HTML in the browser, but I never get an event on the server....

Which component should I subclass for this? (I only want to add a4jsupport, not render any output for the component itself)
Is it correct to add the HtmlAjaxSupport from the 'encodeChildren' method, or do I need to do this at some other time?
