Yes, in general your data class has absolutely no need to know about a request,
so you would normally copy the ActionForm into a Data Transfer Object, and pass
that to your data layer.
So, you would do this:
DynaActionFrom lookupForm = (DynaActionForm)form;
BeanUtils.copyProperties( lookupDto, lookupForm);
AssetData.addAsset( lookupDto);
This allows you to cleanly seperate the UI from your backend code.

Depends... with the default struts valiation is being done before you get to
the action class.
