Subject ClassCastException using the DynaValidatorForm
Date Mon, 07 Jul 2003 16:25:39 GMT

I've got the validation framework working for me using my own form bean 
which is derived from ValidatorForm.  I changed the form bean to be a 
DynaValidatorForm, and now I get a ClassCastException, the guts of which 
is appended below.

What gives?  Am I using the wrong validator form class?  Did I neglect 
to make some other configuration change?

I'm using Tomcat 4.1, Struts 1.1 final, and jdk 1.4.1.
