TableView出错：Either the tableModel parameter or both source and columns parameters must be specified by component.....

用TableView的时候出现这个错误：

 Either the tableModel parameter or both source and columns parameters must be specified by component school/SchoolAdminPayAffiliate/incomeTable

org.apache.hivemind.ApplicationRuntimeException

Either the tableModel parameter or both source and columns parameters must be specified by component school/SchoolAdminPayAffiliate/incomeTable

Stack Trace:

org.apache.tapestry.contrib.table.components.TableView.getTableModel(TableView.java:225) org.apache.tapestry.contrib.table.components.TableView.validateValues(TableView.java:476) ------------------- .page里的代码是： <component id="incomeTable" type="contrib:TableView">         <binding name="source" value="monthIncomeDone"/>         <binding name="columns" value="literal:!isSelected,!affiliateName, email, phone, sumPrice"/>         <binding name="pageSize" value="10"/>         <binding name="element" value="literal:tr"/>     </component>   别被这个错误的提示给误解了，其实很简单，就是 value="monthIncomeDone“没有初始化赋值。你肯定有setMonthIncomeDone(List list);这个方法，给它初始化赋值就好了。
