Question

I am looking for a JSF 2.0 Component that is just an container for other components but do not produce own HTML elements.

My situation is that I have an (already styled) jsf-xhtml component page. Now I need to disable a lot of the rendering.

<ui:component>
    <h:panelGroup layout="block" rendered="#{not empty user.registrations}">...</>
    <h:panelGroup layout="block" rendered="#{not empty user.registrations}">...</>
    <h:panelGroup layout="block" rendered="#{not empty user.registrations}">...</>
    <h:panelGroup layout="block" rendered="#{not empty user.registrations}">...</>
</ui:component>

But I do not want to specify the rendered="#{not empty user.registrations}" fore times. Instead I want to wrapp it with some component like:

<ui:component>
    <xxxx  rendered="#{not empty user.registrations}">
        <h:panelGroup layout="block">...</>
        <h:panelGroup layout="block">...</>
        <h:panelGroup layout="block">...</>
        <h:panelGroup layout="block">...</>
    </xxxx>
</ui:component>

Because the page is already styled (and I fear that this is done in a fragile way) I need an jsf-component (xxxx) that does NOT produce own html elements like div or so.
Does such an jsf-component exit?

You can use

<ui:fragment rendered="#{not empty user.registrations}">
