Hi Murali,
Normally your web IDE account will be updated with latest SAPUI5 version but when you deploy the same application to ABAP stack. It might be on the lower version and certain controls like Toolbar, messageBox will not work as expected in lower versions.
You have to adjust the application either by placing the code in eclipse or by editing your deployed BSP application as per the SAPUI5 version in ABAP stack.
To check the SAPUI5 version in ABAP system, right click your BSP application and choose test application. When the app opens up in browser, open developer tools(if its chrome, press F12) and in the console code sap.ui.version
