正确下载ecside1.3版本<ec:table使用成功，下载extremecomponents-1.0.1.jar想使用其中的<ec:tree>
<ec:tree identifier="id" parentAttribute="parent"
tableId="list1"
items="gncdResultList"
var="gncd"
view="org.extremecomponents.tree.TreeView"
action="${pageContext.request.contextPath}/tree.jsp"
filterable="false"
sortable="false"
>
<ec:row>
<ec:column  property="cdmc" title="模块名" cell="org.extremecomponents.tree.TreeCell"/>
<ec:column  property="dyymdz" title="对应地址" />
</ec:row>
</ec:tree>
抛出异常
