i want to build a composite component already holding some buttons with the possibility for the user to add some others.
<composite:interface>
<composite:attribute name="action" required="false" default="cancel" targets="idCancelButton" />
</composite:interface>
<composite:implementation>
<h:panelGroup
layout="block"
style="margin: 10px 0 10px 0; text-align: right;"
styleClass="commandButtons">
<composite:insertChildren />
<p:spacer width="10" height="10" />
<h:commandButton
id="idCancelButton"
value="Cancel"
</h:commandButton>
</h:panelGroup>
</composite:implementation>
A call to the component would look like this
<buttons:cancelButtonGroup>
<p:commandButton id="idSaveButton" action="save" value="save" />
</buttons:cancelButtonGroup>
I am using Primefaces (3.0M2) (p:commandButton) with Spring Webflow and Mojarra 2.0.6 on Jetty 6.
As already described here using action as attribute name with targets is working fine. Only problem is, that is possibly want to use more than one predefined button inside the component. Then the action attribute wont work anymore. I have been playing around a lot but I can not get a working version where I change the attribute to cancelAction and reference it via action=”#{cc.attrs.action}” from the button. Note that as I am using Spring Webflow, cancel is the name of my transition! I do not want to call some function with return type String. I always get the exception:

I have been reading lots and lots of post and articles about composite component but nobody seems to be mixing them with Spring Webflow. Or it is not noteworthy and my problems is burried somewhere else. 🙂
It seems this is a JSF spec error.
