I'm getting the following in the console when I close a window
"Attempted to remove a component that does not exist. Ext.container.Container: remove takes an argument of the component to remove. cmp.remove() is incorrect usage."
This doesnt appear in ExtJS 4.0.7.
This is a standard Ext.window.Window, containing a form. When you click on the 'OK' button, the window is closed with
which is when I get the error.
I tried to reproduce this but couldn't. Are you able to provide a test case? At a guess I'd say one of the containers in your window isn't destroying itself correctly but it's a little difficult to isolate the problem without an example.
