Uncaught TypeError: Cannot read property 'attr' of undefined

[dbd5]

Hi @cornernote ,

Seems there is a bug somewhere on the js. This error is thrown on the browser console when you reposition a panel. It appears that the panel sort order cannot be saved because of this. Could you take a look?

Thanks

How to reproduce

1. Create a dashboard
2. Add a couple of panels
3. Drag and drop a panel to reposition it
