You should get a ClassCastException if this were really an instance type
problem. Without the stack trace, it's impossible to know what is really
happening.

Here's an additional technique that is a little more work, but just starts
with a ModuleConfig and a form bean name.
ModuleConfig mconfig = ... ModuleConfig for the current module
FormBeanConfig fbconfig = mconfig.findFormBeanConfig("foo");
DynaActionFormClass dafc =
new DynaActionFormClass(fbconfig);
DynaActionForm daf = dafc.newInstance();
