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

To be more specific, here are a couple of example expressions and what they
reference:
#{myBean.foo} references the foo property in the "outer" MyBean instance.
#{myBean.mybean.foo} references the foo property in the "inner" MyBean
instance.
In other words, evaluation just follows the path you explicitly specify ...
the last element represents the property whose value is updated.

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?

Re: how deeply into a bean does myfaces update value references?
Posted by Th...@putnam.com.
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.

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.

<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.
