I tried the Nightly build, but I still get an exception, well, read along :) :
I noticed that there is a nav sample and changed it to
<composite:interface>
<composite:attribute name="act" targets="navbutton" required="true" method-signature="String f1(void)" />
</composite:interface>
<composite:implementation>
<h:commandButton id="navbutton" action="#{compositeComponent.attrs.act}" value="NavButton" type="submit" />
<!-- <h:commandButton id="navbutton" action="nav2" value="NavButton" type="submit" /> -->
</composite:implementation>
(renamed action to act as action has special treatment)
here is the stacktrace:

Actually I ran into this last week so I changed String to java.lang.String,
now I get
javax.faces.el.MethodNotFoundException: javax.el.MethodNotFoundException: Method not found: ezcomp.NavigationHandler_at_508e9.goNav2(void)
at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:92)

at javax.faces.component.UICommand.broadcast(UICommand.java:387)
at javax.faces.component.UIViewRoot.broadcastEvents(UIViewRoot.java:764)
I changed (void) to () and it started working!
So now I have
<composite:attribute name="act" targets="navbutton" required="true" method-signature="java.lang.String f1()" />
Great job!
