Hello, I've been experiencing this problem for almost a week now, and have tried everything possible to figure out the problem: but I simply cannot.
When I load the web page into my browser (developing it on my local machine) it returns this error:
Window win is already registered in the DOM! Make sure you use setDestroyOnClose() or destroyOnClose: true in the constructor.
Please help. It's been frustrating enough. Thanks in advance!
