Accessing parameter of container from mixin

Hi, I am writing a mixin that can be used with submit, actionlink,
linksubmit and other things that support a zone parameter.

 

I need to know the zone name from the container. I can add a zone
parameter to my mixin but it's 'namespaced', ie. doesn't pick up the
zone parameter of the container.

 

I would like to write a defaultZone method but cannot see an obvious way
to get the parameter from the container. I am injecting the container
fine but the zone field is private with annotation rather than exposed
with a getter.

 

The workaround is to duplicate the attribute, eg:

 

                <t:actionlink t:mixins="overlay" zone="x"
overlay.zone="x">...</t:actionlink>

 

This works fine but is not quite as elegant as I'd like!

 

Any ideas?

Thanks, Alfie.
