I agree.  You don't show where the Grid2d is created, nor
evidence that it is created in the right sequence.

Either you need to provide us code we can compile and debug ourselves,
or start instrumenting everything that gets touched as a part of
making an Object2dDisplay work.  Sadly, when people say things like
"here's the relevant code" it often means little.  After all, if they
knew what the relevant code was, they wouldn't have the problem; the
bug would be contained and probably self-evident.

Using either with printf or the debugger you should convince yourself
that the objects that should exist do exist in the right order and
context.
