IllegalArgumentException when using a.b(key) in property in struts 1.1b2

           Summary: IllegalArgumentException when using a.b(key) in property
                    in struts 1.1b2
           Product: Commons
           Version: 1.4 Final
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Bean Utilities
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: wei@ciscoinc.com


I have a example running Struts1.1b2 which is similar to the html-setters.jsp:

    <td align="left">
      <html:text nameid='test' property="testMapBean.mapValue(test)" />
    </td>
Where testMapBean.mapValue(test) is equivalient to a defined bean's
getTestMapBean.getMapValue("test")
This works fine in common 1.3 release. It's broken in common1.4 release. Here 
is Exception using common 1.4 release.

java.lang.IllegalArgumentException: object is not an instance of declaring class
