a4j:support - rendered attribute not working ?

[mhn]

A question regarding a4j:support:

Is the "rendered" attribute working ?
I defined an a4j:support inside tomahawk selectOneRadio and the ajax call is executed ragardless of the "rendered" value (true or false).

e.g.
<a4j:support event="onclick"
reRender="ccw_p1_d3"
rendered="false"
id="aChangeTax"
actionListener="#{MyController.dummyListener}"/>

I tried also EL "#{false}" "#{true}"

The documentation says:
rendered If "false", this component is rendered.

I use a4j 1.1.0, myFaces 1.1.4 and tomahawk snapshot 1.1.4

use <a4j:support onsubmit="return false"....> instead.

you can use there EL also. For example,
<a4j:support onsubmit="return #{foo.bar}"....> where #{foo.bar} return true/false
