How to remove linked composite diagram?

[ea0522]

For objects, there is the option to create a link to a composite diagram using the menu option "New Child Diagram => Select composite diagram".
The fact a diagram is linked is shown via the lying 8 (infinite) symbol in the bottom right corner.
This works fine as long as the diagram is used and sensible.
However, when I just deleted a diagram which was in use as such a composite diagram, the infinite symbol is still shown.
Double clicking the element gives the 'normal' response as it opens the properties window.

Besides this, I couldn't find a menu entry to remove the link before deleting the diagram itself.
Am I missing something?

Right click on element -> select composite diagram -> <none> (at the bottom of the list)

Wow, so simple.
Thanks!

The easier way is to use the context menu New Child Diagram | Composite to uncheck the composite property.
