You seem to be trying to treat the collection of modelActions
as if it were a C array.  This is probably not a good idea.
If you want a collection of actionGroups, you should probably
use something more like:

----------------------------------------------------------
id modelActions;                                                             
int i = 0;
id agentDico[SIZE];
[...]
modelActions = [Collection 
                   create: [self getZone]
                 setCount: speedRangeSize]; 

actIndx = [modelActions begin: [self getZone]];
while ((tmpAct = [actIndx next]) != nil) {

  fprintf(stderr, "Creation du groupe d'action %d\n", i);                    
  tmpAct = [ActionGroup create: [self getZone]];                    
  [tmpAct createActionForEach: agentDico[i]   message: M(step)];    
  i++;
}
-----------------------------------------------------------

Mind you, I'm not sure why you would want to create a 
collection of actionGroups.... But, this would be one
way to do it.  I'm afraid you're trying to do something
that is already done automatically by Roger's activity
machinery.
