Okay, I have reviewed producer fields and even got a chance to exercise them
in an example application. Please answer this question for me.

Is the intent of a producer field to update the produced result if the field
is assigned a new value? If so, perfect. If not, then I run into the same
problem as I do with a request-scoped producer method...it doesn't reproduce
after the Invoke Application phase modifies the field value. Again, I like
the idea of having the producer method be an observer so that I can
reproduce...just an idea.

Btw, in my test using a producer field with Web Beans RI, it appears that
they are behaving badly. Even across separate requests, the result of a
request-scoped producer field is not being updated after the field value
changes...even I change a property on the object held by the field. It
appears as though Web Beans has a reference to some old copy of my object
and even in a debugger I don't see the new value on the bean itself. So
something isn't right. I need to debug more to try to see if I notice what
is going on.
