reassignment of variables to pagecontext attributes in body loop

           Summary: reassignment of variables to pagecontext attributes in
                    body loop
           Product: Tomcat 4
           Version: 4.1.9
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Jasper 2
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: tvanhusen@libra.de


For Tags implementing BodyTagSupport the following is getting generated (at 
the end of body loop) to reassign the exposed variables to pageContext 
attribute objects (which presumably change for each iteration):

    int evalDoAfterBody = _jspx_th_list_forEach_0.doAfterBody();
    supplierInfo = (de.libra.util.vo.ValueObject) pageContext.findAttribute
("supplierInfo");
    if (evalDoAfterBody != javax.servlet.jsp.tagext.BodyTag.EVAL_BODY_AGAIN)
      break;
  } while (true);
  if (_jspx_eval_list_forEach_0 != 
javax.servlet.jsp.tagext.Tag.EVAL_BODY_INCLUDE)
    out = pageContext.popBody();

The reassignment is not generated for tags implementing TagSupport. What is 
wrong. Since TagSupport implements the IterationTag interface(since JSP 1.2) 
which was introduced to allow tag body iteration while writing the body 
immediately to the current JspWriter and not suffer from buffering overhead.
