Problem with BatchSwarm and EZGraph |

Specification:
RH 6.2
Swarm 2.1.1
Objective C
Problem:
My last report was with batchSwarm problem...After detailed searching of
error with gdb debuger I identificate the problem. Problem is here:
>printf("BatchSwarm>create minerals.output\n");
>foodGrapher = [EZGraph createBegin: self];
> [foodGrapher setGraphics: 0];
> [foodGrapher setFileOutput: 1];
> foodGrapher = [foodGrapher createEnd];
> [foodGrapher createSequence: "minerals.output" withFeedFrom:
> [modelSwarm getBugList] andSelector: M(getFoodNumber)];
When I set a "setFileOutput" on value 0 (without saving), my simulation in
batch swarm are working correctly. But when I want a save to file, here is a
problem -> Segmentation Fault...
After it, I identificated, that problem is in :
withFeedFrom: [modelSwarm getBugList] andSelector: M(getFoodNumber)];
But I don't know where...
In ObserverSwarm everything are working correctly (with and without
saving)...
The "getFoodNumber" are return a float value...I have it in Bug.m,
ObserverSwarm.m and BatchSwarm.m
getFoodNumber:
- (float)getFoodNumber { return [modelSwarm getFood1Count]; }
Could anybody help me????
