Major Description
The dealing logical of the warning window of exist cube name is error. The issue can be reproduced using the following steps:
Add a same name cube such as 'kylin_sales_cube', then click the 'next' button to enter a new page, we can't get the warning window.
Click 'Prev' button in the page to return back to the first step,then click 'next' button again,we can get the warning window.
Further if you keep editing the cube,you will get the error message like 01.png.
It should like 02.png anyway.
The 03.PNG shows that the code in 'cubeSchema.js' can check whether the cube name exists, but it's logical is error.
The right dealing logical should be as following:
The program should first check whether the cube exists when we clicked the "next" button.
