In an application of two views where navigation happens via routing with ObjectID , how can the resultant ObjectID data binded to view2.
Code in View2 controller:
onInit method:
onInit: function(oEvent) { var iOriginalBusyDelay, oViewModel = new JSONModel({ busy: true, delay: 0 }); var oRouter = sap.ui.core.UIComponent.getRouterFor(this); oRouter.getRoute("view2routername").attachPatternMatched(this._onObjectMatched, this); //this.getRouter().getRoute("view2routername").attachPatternMatched(this._onObjectMatched, this); // Store original busy indicator delay, so it can be restored later on iOriginalBusyDelay = this.getView().getBusyIndicatorDelay(); // this.setModel(oViewModel, "objectView"); this.getOwnerComponent().getModel().metadataLoaded().then(function() { // Restore original busy indicator delay for the object view oViewModel.setProperty("/delay", iOriginalBusyDelay); }); },OnObjectMatched()
_onObjectMatched:function(oEvent) {
var sObjectPath = "/(" + oEvent.getParameter("arguments").objectId + ")";
this._bindView(sObjectPath);
},_bindView()
_bindView: function(sObjectPath) { var oViewModel = this.getView().getModel(), oDataModel = this.getView().getModel(); this.getView().bindElement({ path: sObjectPath, events: { change: this._onBindingChange.bind(this), dataRequested: function() { oDataModel.metadataLoaded().then(function() {
// Busy indicator on view should only be set if metadata is loaded,
// otherwise there may be two busy indications next to each other on the
// screen. This happens because route matched handler already calls '_bindView'
// while metadata is loaded. oViewModel.setProperty("/busy", true); }); }, dataReceived: function() { oViewModel.setProperty("/busy", false); } }
});
},_onBindingchange()
_onBindingChange: function(oEvent) { var oView = this.getView(), oViewModel = this.getView().getModel(); // No data for the binding if (!oView.getBindingContext()) { this.getRouter().getTargets().display("notFound"); return;
} var oResourceBundle = this.getResourceBundle(), oObject = oView.getBindingContext().getObject(), sObjectId = oObject.Text, sObjectName = oObject.No; // Everything went fine. oViewModel.setProperty("/busy", false); oViewModel.setProperty("/shareSendEmailSubject", oResourceBundle.getText("shareSendEmailObjectSubject", [sObjectId])); oViewModel.setProperty("/shareSendEmailMessage", oResourceBundle.getText("shareSendEmailObjectMessage", [sObjectName, sObjectId, location.href]));
},The navigation from view1 to view2 works well and objectid is also being passed. But currently facing Cannot read property 'indexOf' of undefined error pointing to
_bindView() 4: this.getView().bindElement and
_onObjectMatched 3 this._bindView(sObjectPath);
Any suggestions?
