As far as I can determine, it is not possible to create a DynaActionForm which has a property of type Map. It is also not possible to extend it to be able to accept a property of type Map. This seems like an unfortunate omission, so I'd like to fix it. First, though, I'd like to get some feedback on whether there is a reason it's not currently supported, and on the best way of resolving it.

It's *supposed* to work if you declare the property type to be java.util.Map instead of a concrete implementation of Map. You'll still need to create your own Map instance at the moment -- I do mine in a custom reset() method, but we probably also need a better solution based on an initial expression.
