Question

I want to create a composite component which adds some common meta data to views, like:

<viewController:metadata controller="orderController"/>

the component:

<composite:interface>
  <composite:attribute name="controller" />
</composite:interface>

<composite:implementation>

  <f:metadata>
    <f:viewParam name="id" value="#{cc.attrs.controller.id}" />
    <f:event type="preRenderView"
      listener="#{cc.attrs.controller.initConversation}" />
  </f:metadata>

</composite:implementation>

i do similar things to add a button bar to all views and it works fine, but it seems its not possible with f:metadata.

Am i right or is there something wrong with my code?

thanks

This isn’t possible. The <f:metadata> has to go in the view associated with the view ID. See also the tag documentation (emphasis mine):

Declare the metadata facet for this view. This must be a child of the <f:view>. This tag must reside within the top level XHTML file for the given viewId, or in a template client, but not in a template. The implementation must insure that the direct child of the facet is a UIPanel, even if there is only one child of the facet. The implementation must set the id of the UIPanel to be the value of the UIViewRoot.METADATA_FACET_NAME symbolic constant.
