Keep in mind that all composite components are naming containers, as
such, your targets attribute is incorrect.
It should be targets="<namingContainerId>:navbutton"
So if you have:
<composite:interface>
<composite:attribute name="act" targets="w:navbutton" required="true" method-signature="String f1()" />
</composite:interface>
<composite:implementation>
<ez:wrapper id="w">
<h:commandButton id="navbutton" ... />
</ez:wrapper>
</composite:implementation>
It will work as expected.
