Multiple <cc:insertChildren /> in the same composite component

I'm trying to do a composite component with union of a autoComplete and a dataTable. Like this:

<util:myCustomComp ...>
    <p:column>#{item.code}</p:column>
    <p:column>#{item.name}</p:column>
</util:myCustomComp>

And in CC file:

<p:autoComplete ...>
    <cc:insertChildren /> <!-- Show columns only in autocomplete -->
</p:autoComplete>
<p:dataTable ...>
    <cc:insertChildren />
</p:dataTable>

But the second isnt rendered, render only the first and skeep (in autoComplete or in dataTable).

<p:autoComplete ... />
<p:dataTable ...>
    <cc:insertChildren /> <!-- Show colum开发者_Go百科ns in dataTable -->
</p:dataTable>

Unfortunately, that is not going to work and there are no ways to duplicate components declaratively. Closest what you can get is using <ui:include> instead.

columns.xhtml

<ui:composition ...>
    <p:column>#{item.code}</p:column>
    <p:column>#{item.name}</p:column>
</ui:composition>

Main view:

<util:myCustomComp columnsFile="/columns.xhtml" ... />

Composite implementation:

<p:autoComplete ...>
    <ui:include src="#{cc.attrs.columnsFile}" />
</p:autoComplete>
<p:dataTable ...>
    <ui:include src="#{cc.attrs.columnsFile}" />
</p:dataTable>

(disclaimer: untested, this may break view scoped beans if partial state saving is turned on)

You can use cc:insertChildren in a view only once per composite component, otherwise a duplicate id exception will be thrown. Unfortunately there is no way that could work :-(.
