Subject RE: ParentAware Components Revisited
Date Wed, 22 Oct 2003 18:14:02 GMT
The issue is this:

A component in a child container has access to all components in the
parent 
component manager - if the role isn't found in it's own CM, the lookup
proceeds
to the parent.

However, when looking up a component via a selector, this is not the
case. Since
the selector was found, lookup stops there, irrespective of whether the
hint
passed to the selector really results in a component.

The ParentAware interface enables this - if a selector for
my.Generator/Selector doesn't
have a component for hint "xyz" then it can look up
my.Generator/Selector in the parent
CM and try there.
