jasper compile error with overloaded tag attribute and empty attribute value.

           Summary: jasper compile error with overloaded tag attribute and
                    empty attribute value.
           Product: Tomcat 4
           Version: 4.1.24
          Platform: All
        OS/Version: Windows XP
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Jasper 2
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


For example we have the following tag:

<waacoredesign:insertTransformationGridRow pageIndex="" rowIndex="" 
headerScript="testscript" precedence="true" />

Notice the empty attributes pageIndex and rowIndex

The tag code contains the overloaded attributes as follows:
        /**
         * Sets the row index.
         * 
         * @param iRowIndex The row index.
         */
        public void setRowIndex(int iRowIndex)
        {
                setRowIndex(Integer.toString(iRowIndex));
        }
        
        /**
         * Sets the row index.
         * 
         * @param rstRowIndex The row index.
         * @waa.tag-attribute
         *    required="false"
         *    rtexprvalue="true"
         */
        public void setRowIndex(String rstRowIndex)
        {
                m_rstRowIndex = rstRowIndex;
        }
        
We see the following compile error:
