Sounds like #{UserBackingBean.user} returns a string instead of a user object
Check your "getUser()" method in your backing bean.

I am looking for a best practices for creating BackingBeans with sub

Such as, I want a UserBackingBean that has a User associated with it.
But I have done that, but use:
<h:inputText id="firstName"
value="#{UserBackingBean.user.firstName}">
<f:validateLength minimum="2"
maximum="25"
/>
</h:inputText>
But this gives me this error:
