SAP C4C HTML Mashup initializePane方法里的Inport和Navigation处理

在Cloud Application Studio里创建的HTML mashup，保存到C4C后台后，其元数据再被读取到前端消费，格式如下：

我在C4C UI上指定的Mashup参数，URL的值如下：

成功解析出input为Lead_Info_In:

没有按照我期望的情形进行执行：

MashupHTMLContainer.prototype.initializePane = function() {
		var oController = this.getController();
		var oModel = oController.getComponentModel();
		var oEmbeddingcontext = oController.getEmbeddingContext();
		this._oHtmlPage.setController(oController);
		if (oModel) {
			this._createMashupModel(oModel._oData, oEmbeddingcontext);
			// checks if mashup has an inport or not
			if (this._sInport) {
				// creates inport adapter and attaches it to inport events
				this._oInportAdapter = new InportAdapter(this._sInport, oController, true);
				this._oInportAdapter.on("inportFired", $.proxy(this._onInPortFired, this));


				if (!this._oMashupModel.hasHtmlCode()) {
					// inport and source uri --> fire inport to build complete source uri
					this._oInportAdapter.refire();
					if (this._sInport === "ExtensionFieldsInPort") {
						this._getSourceUriFromModel(this._oMashupModel);
					}
				}
			} else {
				// no inport and no html content --> source uri already valid
				if (!this._oMashupModel.hasHtmlCode()) {
					this._getSourceUriFromModel(this._oMashupModel);
				}
			}
		}
	};

没有执行这个refire：

解析出来的aTargets为空：
