"Cannot retrieve definition for form bean null" warning too late and not precise or unnecessary altogether?

           Summary: "Cannot retrieve definition for form bean null" warning
                    too late and not precise or unnecessary altogether?
           Product: Struts
           Version: 1.0 Final
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Unknown
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: hauser@acm.org

For some simple forms, we noticed that having in the jsp just
 <html:form action="/nextAction.do" >   
is sufficient if the submit button values are retrieved via:
 String yesBtn = request.getParameter("submitPropertyName");
The corresponding form was never declared in the jsp, in fact, it never even
existed as a Java class.

Now it turns out that this was only possible because there was another form
we used globally for language switching (both declared in struts-config.xml and
existing as java class). This language form, however was not named in
"nextAction"'s  <action path=...  ,
only globally.

Once we removed that other (language-switcher) form, we finally got the 
below stacktrace and error message.

Conclusion:
1) The form bean now identified as being null was filled with another form that
  a) wasn't used by this form's action anyway
  b) was only globally declared
2) So, if it is possible to access form values without a form existing, I guess
  a) Either I should get a warning whenever a form uses an action that
     doesn't have a declaration for this form  -- or
  b) let the form not complain at all since doesn't really need the form anyway.
