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.
