Are you able to change the name of Lightning Component. If you are creating "DisplayCase.cmp", it will create "DisplayCaseController.js" as javascript controller for this component. It may create a name conflict.

Hi Balkishan,
Got your point! But even before creating the javascript controller, it is showing the same error.
