[SAPUI5] Model binding events

this.getView().bindElement({
				path: sObjectPath,
				events: {
					dataRequested: (oEvent) => {}, // Executed when a request to server is send
					dataReceived: (oEvent) => {},  // Executed when data from server is received
					change:(oEvent) => {},         // Executed everytime you do ElementBinding
				}
			})

The events for dataRequested and dataReceived are only fired, when data is requested or data is received from a backend. This is not the case, when the requested data is already available in the model from a previous backend call. In such situations, the change event comes in handy.

The same can also be done via XML:

binding="{
  path: '/myEntitySet',
  events: {
    dataRequested: 'onDataRequested',
    dataReceived: 'onDataReceived',
    change: 'onDataChange'
  }
}"

[SAPUI5] securityTokenAvailable

Just noticed, that with UI5 version 1.119.0 the getSecurityToken() function got replaced with securityTokenAvailable().

https://sapui5.hana.ondemand.com/#/api/sap.ui.model.odata.v2.ODataModel%23methods/getSecurityToken

https://sapui5.hana.ondemand.com/#/api/sap.ui.model.odata.v2.ODataModel%23methods/securityTokenAvailable

// Returns the current security token if available; triggers a request to fetch the security token if it is not available.
const token = this.getModel().getSecurityToken() // Deprecated

// Returns a promise, which will resolve with the security token as soon as it is available.
const token = await this.getModel().securityTokenAvailable()
