I wonder if anyone can tell me if it is possible to use a LazyList in a
DynaActionForm as declared in struts-config.xml. I've used ArrayLists
and that seems to work fine. But a LazyList isn't actually it's own
class, and I don't see how to declare it in the config file.
Is this possible?

Your example with the scriptlet is just what you need to do. This is a

So, if my collection is in the local form I define it in a bean:define tag.
