It appears as though the problem is with your use of a form-property
called page - based on what I am seeing around line 141 of the
DynaValidatorForm code, if you have a property named page, it MUST be an
integer, otherwise classcastexception is thrown.
I'm guessing this is to accomodate paged forms (aka wizards)
Try changing the property to have another name, and I think it will fix
your problem.

Re: What Are the Causes For Validation to Throw ClassCastException?
I have changed the property from 'page' to 'pg'. The
ClassCastException problem is gone. However, the
validation.xml that I put in the AppName/WEB-INF is
not doing anything.
In my action mapping (struts-config.xml), I did set
validate=true
and in my validation.xml, I have required set for
the depends attribute for every single text field.
depends=required
I intentionally left every field in those forms blank
and submit forms. But, the Struts did not give me any
warning about that I leave text fields blank.

Re: What Are the Causes For Validation to Throw ClassCastException?
Do you also have /AppName/WEB-INF/validator-rules.xml?
Without that the validation won't work. Also make sure that you have the
proper version of the validator jar.
Assuming those things are correct, take a look through your tomcat logs,
I bet you are actually getting an error of some sort.

RE: What Are the Causes For Validation to Throw ClassCastException?
Jen,
DynaValidatorForm ALREADY has a page field so leave it out:
http://struts.apache.org/api/org/apache/struts/validator/DynaValidatorForm.h
tml
As for your validation not working with pg that's because the validator
uses the field name page to figure out which validations to test in
multi-page validations.
Additionally, WHY are you requiring a page field in your formset? It should
be a hidden variable out of the view of the user so there is no need to
validate it. Without it, the plugIn should assume page=0 and do the most
basic of validations in your formset.
Regards,
David
