I wanted to run a test: a CallSubDelayed on an object-variable referring to an object that "no longer exists" (?).
So I created a B4J project "on the fly" and I came across some rather strange things (one of which I don't even write... at least for now).
It is not easy to explain in words what the problems are, so
A class has an object variable which refers to an object instantiated elsewhere.
This object is set to null. If inside the class I use a CallSubDelayed "to the variable", the method is executed as if the object still exists.
Another problem is:
clsRoom exists, of course, and the object in "3" too.

B4X:
'gmapRooms.Get(3).As(clsRoom) = Null' *** --> Compile-time error message ***
