DA> I suppose it depends on whether insertFacet attaches a facet to the parent DA> component or whether it inserts the contents of the facet inline. I suspect DA> the latter. In that case, you woud need to wrap insertFacet in <f:facet>, DA> right? <cc:insertFacet> The presence of this tag in a <composite:implementation> section must cause the named facet to be taken from the facet map of the top level component and inserted as a facet child of the component in which this element is nested. javax.faces.CompositeFacet encodeBegin() and encodeEnd() must take no action for this renderer. Due to the specification of the <composite:insertChildren> tag handler, the component passed to the encodeChildern() method of this renderer will be the component with component-family javax.faces.Output and renderer-type equal to the one for this renderer. The implementation of encodeBegin(), must obtain the component attribute value under the key given by the value of the symbolic constant UIComponent.FACETS_KEY from the attributes map of the argument component. If not found, throw IOException. This value is referred to as "facetName" for discission. Find the closest ancestor composite component in which the argument component is nested. If no such component can be found, thow IOException. Otherwise, get the facet whose name is "facetName". If found call encodeAll() on the facet. AS> However, if I define a second component, foo:inner, that exposes the AS> same facet: AS> <composite:interface> AS> <composite:facet name="caption"/> AS> </composite:interface> AS> <composite:implementation> AS> <composite:renderFacet name="caption"/> line B^^^^^^^^^^^^^^^^^^ AS> </composite:implementation> AS> And then attempt to pass the facet into the foo:inner component from the AS> foo:outer implementation: AS> <composite:implementation> AS> <foo:inner> AS> <composite:insertFacet name="caption"/> line A^^^^^^^^^^^^^^^^^^ AS> </foo:inner> AS> </composite:implementation> 1. when the using page executes, the children <f:facet name="caption"> are placed in the facet map of the top level component for foo:outer. 2. when the insertFacet on line A executes, the children are moved from being facet children of the top level component for foo:outer to being facet children of the top level component for foo:inner 3. when the renderFacet on line B executes, according to the spec, it should find the facet and render it. It looks to me like an impl bug. Can you file it? Ed [1] http://java.sun.com/javaee/javaserverfaces/2.0/docs/pdldocs/facelets/comp...
