ManagedBean inherits another MB. How to reuse the main class JSF as a component?

Question

My problem is a little bit complex, but I'll give an example.

I already have a user.xhtml page (and a MB that uses it) where I register an user

<p:outputLabel value="Name:" /> <h:outputText value="#{userMB.bean.name}" />
<p:outputLabel value="e-mail:" /> <h:outputText value="#{userMB.bean.email}" />
etc...

Now I create an UserAdmMB that inherits UserMB, with another fields. I want to reuse the XHTML that exists, like using <ui:include>:

<ui:include src="user.xhtml" />
<p:outputLabel value="Address:" />
<h:outputText value="#{userAdmMB.anotherbean.address}" />

But the first XHTML already has userMB in it (to be used in another access point). How is the better way to do that?

Please step back and reconsider the design all over again from scratch. — Tiny, Jan 10 '15 at 09:01

Refactor the bean as <ui:param> of <ui:include>.

The new include:

<p:outputLabel value="Name:" /> <h:outputText value="#{user.name}" />
<p:outputLabel value="Email:" /> <h:outputText value="#{user.email}" />
...

The clients:

<ui:include src="user.xhtml">
    <ui:param name="user" value="#{someBean.user}" />
</ui:include>

<ui:include src="user.xhtml">
    <ui:param name="user" value="#{someAdminBean.user}" />
</ui:include>
