ui:include disables menu

Question

<rich:tabPanel id="profileChangePanel" switchType="client" >
    <rich:tab id="profileCompetenceTab" label="Kompetenser" labelWidth="80">
        <ui:include src="/panels/tab1.jsp" />
    </rich:tab>

    <rich:tab id="profileInfoTab" label="Information" labelWidth="80">
        <ui:include src="/panels/tab2.jsp" />
    </rich:tab>

    <rich:tab id="profileReferenceTab" label="Referenser" labelWidth="80">
        <ui:include src="/panels/tab3.jsp" />
    </rich:tab>

</rich:tabPanel>

If I include all code in /panel/tab1.jsp instead of the ui:include everything is OK. If I use the ui:include nothing is rendered. Not even the tab-panel.

Why? Workarounds?
