In the view2 where you have sap.ui.getCore().byId("SelectCondType").setSelectedKey(response.Condtype);
can you do this to check if you got the control.
var test = sap.ui.getCore().byId("SelectCondType");
console.log(test);
console.log(response.Condtype);
It is easy to debug in Chrome. these will print out in the console window.
