树形结构选择报错问题！

由于是代码生成的主从表页面中！使用  easyui-combotree树形下拉选择！  但是页面加载时  控制台报错！

<input id="parentId" name="parentId" type="text" style="width: 150px" class="inputxt easyui-combotree"
                                                      data-options="panelHeight:'220',
                                                url: 'placeController.do?datagrid&field=id,placeName',
                                                loadFilter: function(data) {
                                                         var rows = data.rows || data;
                                                         var win = frameElement.api.opener;
                                                         var listRows = win.getDataGrid().treegrid('getData');
                                                         joinTreeChildren(rows, listRows);
                                                         convertTreeData(rows, 'placeName');
                                                         return rows;
                                                },
                                                onSelect:function(node){
                                                         $('#parentId').val(node.id);
                                                },
                                                onLoadSuccess: function() {
                                                         var win = frameElement.api.opener;
                                                         var currRow = win.getDataGrid().treegrid('getSelected');
                                                         if(!'${test.id}') {
                                                                  //增加时，选择当前父菜单
                                                                  if(currRow) {
                                                                        $('#parentId').combotree('setValue', currRow.id);
                                                                  }
                                                         }else {
                                                                  //编辑时，选择当前父菜单
                                                                  if(currRow) {
                                                                        $('#parentId').combotree('setValue', currRow.parentId);
                                                                  }
                                                         }
                                                }"/>

此处代码在其他页面运行正常
