Aleks,
You are right, the ResponseElement interface does not allow lookup of a
specific nested object. I don't believe that it was a particular design
decision, probably just overlooked. Also, the default implementation of
response elements stores the nested elements in a private ArrayList, so there
is no way to extend and cast it and then lookup by name as a workaround either.
The only thing I can think of is if you add the nested object using the
setAttribute(String key, Object value) method (instead of add(ResponseElement
re), then there is a getAttribute(String key) method. Although, sematically
this may not be the correct way to nest elements, it might work.
In the future, we probably ought to consider adding a get(String name) method
to the interface. Mike, what do you think?
