dojo widgetlist将值传递给模板

当尝试在widgetlist数据mvc子道具属性中使用at值时，我得到一个错误 dojox.mobile.ListItem模板：erpValue

但是如果我把这个值赋给一个静态字符串，它就可以正常工作了。exvalue:SomeValue 从文档中可以看出，这应该是可行的，因为我看到了将标签值映射到at

        <ul class="searchProductList" data-dojo-type="dojox.mobile.EdgeToEdgeList" id="repeatId1" class="tabletProductList"
                    data-dojo-props='children: searchv2.productList.items'
                    data-dojo-mixins="dojox/mvc/WidgetList,dojox/mvc/_InlineTemplateMixin"
                    data-mvc-child-type="dojox/mvc/Templated"
                    data-mvc-child-mixins="dojox/mobile/ListItem"
                    data-mvc-child-props="clickable: true, 
                                            indexAtStartup: this.indexAtStartup,
                                            variableHeight : 'true',
                                            erpValue: at(this.target, 'erpPartNumber'),
                                            uniqueid: at(this.target, 'uniqueId'),
                                            onClick: function(e){                                                   
                                                console.log('Target::' + JSON.stringify(this.target));
                                                console.log(this.indexAtStartup); return true;}">
                <script type="dojox/mvc/InlineTemplate">
                    <div class="mblListItemLabel">
                        <div class="productListContent"
                            data-uniqueid="${erpValue}">
                                                    </div>
                                            </div>
                                     </script>
          </ul>

什么是完整的错误消息？它发生在哪一行？把完整的错误放在上面好的，这一定是一个错误，它在1.9.3中工作。。。但不是在1.8.1中。我必须看看是否可以升级
