JSF composite component validation -

i want create composite component , attach validators it's children, want message validation attached composite component, not it's child.

in page using composite component want this:

<zzz:mycomponent id="my" /> <h:message for="my" />

now doesn't work, because message component's child, not composite component itself. how make whole component?

or better, add validator composite component, like:

<zzz:mycomponent id="my" validator="#{bean.validatecomposite}" />

and receiver booleans array value, because inside composite component there h:selectbooleancheckbox elements. possible?

maybe late respond on question how should it:

<zzz:mycomponent id="my">    <f:event type="postvalidate" listener="#{bean.dovalidation}"/> </zzz:mycomponent>

the dovalidation called after validation of childs in 'container'. method llooks this:

public void dovalidation(componentsystemevent event) {     ... }

and have 2 options in method:

access child components (event.getcomponent().getchildren() ) , whatever want values submitted on childs.
or loop on facesmessages , reallocate clientid placed on container component (id = my)
