how deeply into a bean does myfaces update value references?

hello everyone,

I have a jsp and backing bean.  The jsp has a field like
<h:inputText  value="#{myBean.foo}"

MyBean.java has the "foo" property, and it also
has a property like

      private MyBean myBean = null;
 with getters and setters

I save a copy of MyBean here before any update so I can
reset or cancel
the update as needed, and restore the original MyBean to
session.

I find if I enter something in the foo field of the jsp, the
foo property
in the
saved original untouched MyBean property is also updated.

Does my faces search a backing bean for all references to a
property
and update all references?  That's what it looks like it's
doing, but is
that what
you see?

Thanks in advance for your help.
Tom

<h:inputText  value="#{myBean.foo}"

On update:
Look for "myBean" in the scoped maps (request,
session, application).

If not found, create a new instance of mybean.
call setFoo() on the instance of my bean.

Andrew,

would myfaces also find the property 'MyBean mybean' 
which is defined in
MyBean and call
setFoo on that reference?

for example, I've got

MyBean class
      private String foo  (with getters and setters)
      private MyBean myBean (with getters and setters

before the update page renders, I save a copy of MyBean in
itself.

so the MyBean copy also has a foo reference.

what it looks like is that when the page is submitted,
myfaces updates the
visible
foo property but also find the foo property in the 'MyBean
myBean'
property.

does that make sense? and is that the intended behavior of
Myfaces?

I'm keeping a copy of the bean in itself to be able to
reset the update
form.

I know a Reset button of type=reset works, but on this page
there are lists
which could cause a form submit and I can't reset the
update form to
the original state.

Thank you for the response.
Tom

It should never look for (or set)
"myBean.myBean" unless you use it
somewhere in the EL or have it as a managed property in the
faces
config. What code (including EL and managed properties)
refers to the
"myBean" property?
