Forcing materialization of a dynamic proxy object

[Coup, Robert Muir]

Hi all,

I have searched through the archives and can't seem to find any answer.
How can I force a proxy to materialize its object, or to replace the
proxy object witht the real object?

I have a collection of Group objects within a Paper object. Group's are
proxied dynamically (group, staffgroup), and can be of two types -
groupimpl or staffgroupimpl. Groupimpl is the parent of staffgroupimpl.

When the Paper objects collection arrives, it is a bunch of proxy
objects.
In one operation, I must manipulate the staffgroups in the paper.groups
collection.

For (Iterator iter=groups.iterator; iter.hasNext;) {
        Group g = (Group)iter.next();
        if (g instanceof StaffGroup) {
                ...
        }
}

This fails because none of the objects are seen as StaffGroup's. Even
attempting to resolve them through a call to .getSomething() seems to
leave the objects as $Proxy2's....

Ideas?

Thanks,
Robert Coup
