    With ui:include the id will be duplicated.

    You can pass a parameter to your included xhtml and prefix your id

    <ui:include src="included.xhtml">
    <ui:param name="idPrefix" value="myFormIdPrefix"/>
</ui:include>

    In the included xhtml

    <h:form id="#{idPrefix}_foo"/>

    Now it is possible to reference the id as #{idPrefix}_foo
