Problem with Object2dDisplay

[Konrad Lang]

Hello!

I got a Activity group in which the movement of some objects should be
displayed. The objects are dynamically created and destroyed within a
dynamical model swarm, used as populations in some GA.
The whole model swarm is destroyed and recreated within the global
schedule.
              
The objects are located in a Discrete2d world, their
position should be displayed in ZoomRaster - this works fine for the
first run - Display is OK, all movements appear -  but if I try
destroying and recreating the ZoomRaster and the Object2dDisplay as an
Activity within the global schedule , the
Object2dDisplay seems to point to some different objects when it gets the
display message. 

function: _i_Object_s__doesNotRecognize_(), file: DefObject.m, line: 635
ObjectX does not recognize drawX:Y:*** execution terminating due to
error

I also tried to send the draw method directly to the objects, with the
same effect - without the display methods the whole system works fine, all
pointers are ok ...
??? Any idea what could happen when using the Object2dDisplay ???

Thanks for any help in advance

At the source of every error which is blamed on the computer you will find
at least two human errors, including the error of blaming it on the computer.
