Description
The code does not expect a object to be null which is what happen when deleting one so any new add will crash the listener.
To reproduce:
- make you user advanced
- create a new page and add a UIExtension object to it with "toto" in extension point and id fields
- save
- edit and remove the object
-> error in the log
