RE: Probes

[Fred Wan]

That is, I believe, the usual procedure. But here I want to include a
variable from the base class in a probemap from a derived class. If I state
a few variables of the derived class to appear in the probemap and I add one
from the base class I get a runtime error (Attempt to add a null probe).
Here's the fragment from the constructor of the derived class (xPos is the
variable from the base class):

  EmptyProbeMapImpl probeMapSimpleBug = new EmptyProbeMapImpl(aZone,
getClass());

  probeMapSimpleBug.addProbe(getProbeForVariable("bugColor"));
  probeMapSimpleBug.addProbe(getProbeForVariable("periodsSinceEaten"));
  probeMapSimpleBug.addProbe(getProbeForVariable("xPos"));

  Globals.env.probeLibrary.setProbeMap$For(probeMapSimpleBug,getClass());
