sorry to be pedantic but I wasn't sure about wizard or operation :)

I don't quite know how to categorize its 'number of implementations' multiplicity - I've thought
about it a fair bit too!

the only thing I could think of was another colour altogether and call it: "One per form or
collection of forms" and that's not very good due to the ambiguities with java.util.Collection!!

Seeing as DynaActionForm means you don't need to implement any ActionForm classes the situation
is
even more complex!

sorry I could only point it out and not solve it.
