[jsr-314-open] DRY and form with JSF 2

[Dan Allen]

+1. Exactly what I was thinking.

It appears we have two correlated issues here. I've found a need for the
backreference in the past. It can be linked at build time. Of course,
programmatic access would need to be aware of it if the tree is modified in
a way that breaks the reference. That should be mentioned in the issue
report, not necessarily solved here.

it would be way less overhead, if there would be a reference back from
the inputText to the outputLabel that is actually stored with the
inputText and not just logically defined by the 'for' attribute of
label. If a reference to the outputLabel would be stored in a collection
with the inputText by setting the 'for'-attribute on outputLabel it
could be just taken from there and wouln't require runtime-walk of the
component-tree to be retrieved.

Such a mechanism to define (and resolve) inter-component-relationships
more efficiently would be helpfull in many other cases where components
logically belonging together are not in a parent-child (or parent-facet)
relationship. A good (and recently discussed) example is form-based
validation by a custom-validator where the validator would have to get
access to (logically, but not nessesary hirarchically) related
components as well.
