There is a <composite:clientBehavior> tag in the 2.0 version of
JSF that comes with GlassFish, and it appears to work as advertised by
Alexandr and Andy below.
<div><br>
</div>
<div>But, as Alexandr points out, it’s not documented in the PDL
docs, nor could I find any mention of it in the spec (or Ed’s book,
either).</div>
<div><br>
</div>
<div>This is a vital tag that lets page authors attach ajax
functionality to components within composite components. I see no
reason why it should not be documented.</div>
<div><br>
</div>
<div>Does anyone know why this tag was not documented in the first
place, or what the plans are for its future? Anyone know if it works
with MyFaces 2.0?</div>
<div><br>
</div>
<div>If there’s not a compelling reason for blacklisting it from the
docs, can we document it?</div>
<div><br>
</div>
<div>Thanks,</div>

<blockquote>Sure, the composite client event tags are not included in
the PDL doc.<br>
There is one <composite:clientBehavior> tag with
attributes: 'name' -<br>
the virtual event name that composite component has.<br>
'default' "true/false" defines the default event that is enclosed<br>
<f:ajax> tag serves if 'event' attribute was omited.<br>
'event' - the real event name for target component.<br>
'targets' - space-delimited list of component id's for which composite<br>
component behavior or <f:ajax> tag will be redirected.<br>
<br>
The model with 'for' attribute was the first implementation but it was<br>
replaced wit 'virtual' event model.<br>
