Hi,
I have a test application with following method executed on button press:
_loadData: function(){ // FIRST ODATA CALL this.getView().byId("idPanelOne").setBusy(true); this.getOwnerComponent().getModel("oDataService").read("/DashboardDataSet", { "async": true, "urlParameters": {"$expand": "DashboardTimeboxSet"}, "filters": [ new sap.ui.model.Filter({ path: "SprintStatus", operator: sap.ui.model.FilterOperator.EQ, value1: "01" }) ], "success": function(oData) { this.getView().getModel("oModelOne").setData(oData.results[0].DashboardTimeboxSet); this.getView().byId("idPanelOne").setBusy(false); }.bind(this), "error": function(oError) { var oErrorBody = JSON.parse(oError.responseText); alert(oErrorBody.error.message.value); } });
// SECOND ODATA CALL // This call should take 2 seconds longer (WAIT UP TO 2 SECONDS in oData) this.getView().byId("idPanelTwo").setBusy(true); this.getOwnerComponent().getModel("oDataService").read("/DashboardDataSet", { "async": true, "urlParameters": {"$expand": "DashboardStorySet"}, "filters": [ new sap.ui.model.Filter({ path: "SprintStatus", operator: sap.ui.model.FilterOperator.EQ, value1: "01" }) ], "success": function(oData) { this.getView().getModel("oModelTwo").setData(oData.results[0].DashboardStorySet); this.getView().byId("idPanelTwo").setBusy(false); }.bind(this), "error": function(oError) { var oErrorBody = JSON.parse(oError.responseText); alert(oErrorBody.error.message.value); } });
// THIRD ODATA CALL this.getView().byId("idPanelThree").setBusy(true); this.getOwnerComponent().getModel("oDataService").read("/DashboardDataSet", { "async": true, "urlParameters": {"$expand": "DashboardActivitySet"}, "filters": [ new sap.ui.model.Filter({ path: "SprintStatus", operator: sap.ui.model.FilterOperator.EQ, value1: "01" }) ], "success": function(oData) { this.getView().getModel("oModelThree").setData(oData.results[0].DashboardActivitySet); this.getView().byId("idPanelThree").setBusy(false); }.bind(this), "error": function(oError) { var oErrorBody = JSON.parse(oError.responseText); alert(oErrorBody.error.message.value); } });
}The 3 read() methods are calling an odata service in sap system.
The odata method of the second call has a WAIT UUP TO 2 SECONDS in its code.
So i would expect that may PanelTwo is in busy state 2 seconds longer than One and Three.
But it isn't.
One and Three need the same time as Two.
If I remove the second call One and Three are both loaded nearly instant.
It seems that UI5 is waiting for all 3 calls to be finished before their success functions are called.
Any Idea how the success functions can get called independently?
Thanks & Regards,
