Hi all and a merry christmas to you.
Let's see if someone is online today :)

I have some handlers that do an instanceof check. I found that this
doesn't work at my side, do I need another addOn or something to make
this work ?
The addOns I currently have configured are as follows

I guess this should be working straightforward ...
