i'm the user of beehive.
And in the process of developing, i came up with this question.

i want to make a taglib of repeater.

and i write code like these.

package com.jumpintl.taglib;

import java.io.IOException;

import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.BodyContent;

import org.apache.beehive.netui.tags.databinding.repeater.Repeater;
import org.apache.beehive.netui.tags.databinding.repeater.RepeaterHeader;
import org.apache.beehive.netui.tags.databinding.repeater.RepeaterItem;
import org.apache.beehive.netui.tags.rendering.TableTag;

import com.mockrunner.mock.web.MockBodyContent;

public class Datagrid extends Repeater {

   /**
    *
    */
   private static final long serialVersionUID = 9132424393043653581L;

   private String tagId;

   private String query;

   private String sharedController;

   private String xmlPath;

   //private TableController tableController;

   public Datagrid(){
       //XMLDatagrid datagrid = tableController.getDatagrid();
   }

    public int doStartTag() {

       RepeaterHeader repeaterHeader = new RepeaterHeader();
       repeaterHeader.setPageContext(pageContext);
       repeaterHeader.setParent(this);

       RepeaterItem repeaterItem = new RepeaterItem();
       repeaterItem.setPageContext(pageContext);
       repeaterItem.setParent(this);


       //repeaterHeader.doInitBody();
       try {
           super.setDataSource("sharedFlow.tableFlow.tableDatas");
           super.doStartTag();
           super.doInitBody();

           int retRepeaterBody = 2;
           while (retRepeaterBody!=0) {

               repeaterHeader.doStartTag();
               repeaterHeader.doInitBody();

               MockBodyContent body = new MockBodyContent(
pageContext.getOut());
               body.write("<table>"
                           + "<tr>"

               repeaterHeader.doAfterBody();
               repeaterHeader.doEndTag();


               body.clearBody();
