Hi
In myfaces we don't have <composite:clientBehavior> tag. The reason is that we don't know which attributes this tag has, how it looks like or where there is some example. In theory it works like <composite:actionSource>, <composite:valueHolder>, <composite:editableValueHolder>. I pointed this issue multiple times (really a lot of times but it seems nobody took that seriously). Just take a look at:
http://markmail.org/message/dxlpoa3qgul7uuns?q=composite:clientBehavior
As soon as any documentation is available on mojarra javadoc I'll do the necessary stuff on myfaces.

I will file a spec issue on this.
Thanks for catching it.

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).
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.
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?
If there’s not a compelling reason for blacklisting it from the docs, can we document it?
Thanks,

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