ajax dwr 调用对象问题

Question

<script type='text/javascript' src='<%=request.getContextPath()%>/dwr/interface/reportTable.js'></script>
  <script type='text/javascript' src='<%=request.getContextPath()%>/dwr/interface/reportField.js'></script>
  <script type='text/javascript' src='<%=request.getContextPath()%>/dwr/engine.js'></script>
  <script type='text/javascript' src='<%=request.getContextPath()%>/dwr/util.js'></script>
reportTable.setCode(DWRUtil.getValue(code));
reportTable.setName(DWRUtil.getValue(fname));
reportTable.setDataType(DWRUtil.getValue(length));
reportTable.setPrecision(DWRUtil.getValue(precision));
reportTable.addField(reportTable);错误提示：Missing method or missing parameter converters: reportTable.addField该方法存在，应该是缺少参数转换，求高手怎么能转换为reportTable对象呢？？给出详细代码:）还是dwr不支持直接对对象进行处理？注：reportTable是定义的对象

Answer 1

dwr.xml中的部分配置
<create creator="new" javascript="reportTable">
  <param name="class" value="com.goodinfo.csreport.base.Table"/>
</create>
<create creator="new" javascript="reportField">
  <param name="class" value="com.goodinfo.csreport.base.Field"/>
</create>

Answer 2

在dwr.xml中配置<convert>标签:
<convert converter="bean" match="数组中每个元素的类型">
</convert>
