需求说明：
在bos界面新建了一个F7 带有分组的
waf2界面上实现这种效果
步骤：
1、
customF7=wafPromptSpecial_ExpenseType
2、
3、
4、
6、
8、后台代码

9、点击组别过滤query
备注：这样加的F7发现保存的时候数据没有保存上去，
8.5 8.6版本 js中这里做了调整
/*该函数用于当点击树的节点时，返回过滤条件，该方法由开发人员按自己需求进行覆盖
注意：选中某个节点时，会把 treeNode.id 传到后台，后台可以在 request.getParameter("parentId") 取到，所以后台想办法取得request即可
树 是异步加载的
*/
/* _getTreeNodeFilter: function(){
var selectedNodes = this.tree.wafTree('getSelectedNodes'),
ret = "";
if(selectedNodes.length>0){
var treeNode = selectedNodes[0];
ret = "treeid.id = '" + treeNode.id + "'";
// ret = treeNode = '" + treeNode.id + "' ;
// ret = "treeNode = '" + treeNode.id + "'";
}
//刚刚弹出F7时，没有选中的节点，所以会返回过滤条件为空，因此数据会全部加载
return ret;
}, */
_getSpecialFilter: function(){
var selectedNodes = this.tree.wafTree('getSelectedNodes');
var treeNode = selectedNodes[0];
if(!selectedNodes || selectedNodes.length < 1){
return null;
}
var ret=waf.parseSql.getFilter("treeid.id", "=", treeNode.id)
var obj={filterItems:ret};
return obj ;
}
