You could annotate this as an event handler directly.

I do not see the point of doing this as you can just check if it is null if I understand that correctly. If not please correct and explane the exact purpose to me.

As you can see a few lines above, this method is annotated with an Event: It gets called every time the user changes his own status.
Hence I always have to replace it then.
And for the first part: I cannot do that because initially this component is no part of the HBox (you remember, the thing with importing the by now outdated jar into the SceneBuilder...). To avoid that, it gets dynamically added.

But thinking about it, it may be possible, however I do not know if it'll work as bug-free as this implementation: As soon as you initialize this variable somewhere else, you might encounter a bug that duplicates it.

What if, instead of regenerating the whole control, we would just change the displayed information in the event handler?

It could be possible if we make some changes to the underlying ContactControl.
The question however is: Should it be done?

Oh, and also: there is a difference between ownUserControl and ownContactControl.
