DynaActionForm.get("param") returns an empty string; used to return null

           Summary: DynaActionForm.get("param") returns an empty string;
                    used to return null
           Product: Struts
           Version: 1.1 RC1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Controller
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: jpl@remotejava.com


I tried to upgrade from 1.1b2 to 1.1rc1 today. My application became broken because of the apparent change in behavior of DynaActionForm. The get method used to return null if a parameter declared as form property was not provided by the client. As of 1.1rc1, it returns an empty string. I'd say that the "return null" behavior was better, as it allowed to differentiate between an empty value and no value at all. Note that neither of these behaviors is well documented in DynaActionForm's API. I am entering this as a bug because it leads to regression problems and I could not find any justification for the change in the mailing list archive.
