Hi<br><br>This is a message on behalf of Jakob Korherr:<br><br>&quot;.....Working on this issue I found out that the hidden property can not be 
added for composite:actionSource, composite:editableValueHolder and 
composite:valueHolder, because those tags do not create a 
java.beans.FeatureDescriptor, but a 
javax.faces.view.AttachedObjectTarget and this one does not include a 
hidden property. Thus this clearly is a spec issue....&quot;<br><br>On myfaces we don&#39;t see how this attribute should work. The description says:<br><br>&quot;....The &quot;hidden&quot; flag is used to identify features that are intended only 
for tool use, and which should not be exposed to humans.....&quot;<br><br>It has sense on composite:attribute, composite:facet and composite:interface, but it doesn&#39;t on composite:actionSource, composite:editableValueHolder and 
composite:valueHolder.<br><br>regards,<br><br>Leonardo Uribe<br>
