The error message is normal. There are a couple of ways accomplish what you 
want to do. In general, if actions on a
schedule have to start after the initial period, you need to schedule the 
activation of that schedule from another
schedule. In this case (assuming that these actions are the only ones in the 
model) you can use this method:

mainSchedule =  [Schedule createBegin: aZone];
mainSchedule =  [Schedule createEnd];

repeatSchedule  = [Schedule createBegin: aZone];
repeatSchedule  = [repeatSchedule setRepeatInterval: 1];
repeatSchedule  = [repeatSchedule createEnd];

[repeatSchedule at: 0 createActionForEach: ua_array message: 
M(calcRatingAgentReputation)];
[repeatSchedule at: 0 createActionTo: resultGraph  message: M(step)];
[repeatSchedule at: 0createActionTo: self message: M(checkToStop)];

[mainSchedule at: 0  createActionTo: resultGraph  message: M(step)];
[mainSchedule at: 0 createActionTo: repeatSchedule message: M(activateIn:) : 
aZone];

[mainSchedule activateIn: aZone];

Note: I haven't tested this. My recollection is that the first execution of 
repeatSchedule would come on the first
timestep after the activation, so that you need to activate it at 0 on 
mainSchedule. Correct me if I'm wrong.

Another,and messier way, if the only thing you want to avoid is to call 
ua_array and self on the first step, would be to
reroute these messages to messages in the ModelSwarm and dispatch the message 
to calcRatingAgentReputation and
checkToStop only when step >= 1.
