I tested it now. It also works in the EM. The only limitation is that  
it works with installed extensions only. This is fine while  
installing an extension. The only time an error occurs is when you  
view an extension's details and uninstall it from that screen.

A way to solve this could be to turn off the rendereing of the form  
fields while an extension is not installed.
What do you think?
