Problem with BatchSwarm and EZGraph

[Marian Mihalo]

Well,

could anybody say me a difference between:

withFeedFrom:[modelSwarm getBugList]  andSelector: M(getFoodNumber)];

and

withFeedFrom:self  andSelector: M(getFoodNumber)];


How function is with self, what is returned when I use a "self" etc.?????

In ObserverSwarm.m I have in the same object(Graph): withFeedFrom:self
andSelector: M(getFoodNumber)];
and in BatchSwarm.m I have : withFeedFrom:[modelSwarm getBugList]
andSelector: M(getFoodNumber)];

Thanks for your help...

Marian
