将过滤器应用于Sap.m.Input的建议项时，输入值将被删除

Question

我正在研究Sap.m.输入建议项。输入的建议工作正常，但是当我从建议列表中选择一个项目，然后删除该值并输入新值时，它将自动删除新输入的值，而不会显示任何建议。我调试了代码，并在oBinding.filters（）行中删除了该值。我的代码如下，

<Input id="input" placeholder="{i18n>input}" editable="true" startSuggestion="2"
                showSuggestion="true" suggest="handleSuggest"  
                 suggestionItemSelected="onSelectedItem" 
                 suggestionItems="{path:'abc>/abSet',templateShareable:true, parameters:{select: 'ab,bc'}}">
                    <suggestionItems growing="true" growingScrollToLoad="true">
                                <core:Item key="{abc>ab}" text="{abc>ab} {abc>bc}"/>
                    </suggestionItems>
                </Input> 

控制器

handleSuggest: function (oEvent) {
            var sTerm = oEvent.getParameter("suggestValue"),
                oSource = oEvent.getSource(),
                oBinding,
                aFilters = [];
            oSource.setBusy(false);
            if (sTerm) {
                aFilters.push(new Filter("bc", FilterOperator.Contains, sTerm));
                aFilters.push(new Filter("cd", FilterOperator.EQ, ""));
                aFilters.push(new Filter("de",FilterOperator.EQ, ""));
            }

            oBinding = oSource.getBinding("suggestionItems");
            var Filters = [];   
            Filters.push(new Filter({
                filters: aFilters,
                and: true
            }));

            oBinding.getModel().setSizeLimit(500);
            oBinding.filter(Filters);


        },

        //Once the suggestion BP is choosen retreiving the key
        onSelectedItem: function (oEvent) {
            var sItems = oEvent.getParameter("selectedItem");
            if (sItems !== null)
                filterValue = sItems.getKey();

        },

非常感谢您的帮助

对我来说，解决方案是从key聚合中的<core:Item />元素中删除属性suggestionItems。在版本1.44之后，发生了一些更改，并且属性key引起了一些奇怪的行为，但我仍然无法弄清原因。
