Editing Observer Swarm. Can you tell me this?

[Paul E. Johnson]

I'm working with a space that is ten dimensional, and I want to display
it two dimensions at a time in 5 2D objects of the familiar sort:
zoomRasters that have Object2dDisplays mapped onto them.(heatbugs etc).

Of course I could create a series of named rasters and spaces, but I'm
thinking of doing it in a way that is scalable, so I can create spaces
in a loop and add them to the end of "spaceLists" (the way we create
agents and add them to lists, for example).  Before I write all this
code out, I figured I'd check with y'all to see if there is some big
mistake I'm going to make in the Scheduling (buildActions) sections of
the code. 

If you can consider an out-of-context code snippit, suppose you've got
something like this in buildActions in ObserverSwarm. From buildObjects,
we already have 2 graphs (instabilityGraph,stabilityGraph), 2 rasters
(worldRaster and proposalRaster), and 3 Object2dDisplays (voterDisplay,
policyDisplay,proposalDisplay). (2 of the Object2dDisplays get sent to
one of the rasters). The buildActions schedules their updates like so::
 
    displayActions = [ActionGroup create: [self getZone]];
 
    [displayActions createActionTo: instabilityGraph     message:
M(step)];
    [displayActions createActionTo: stabilityGraph       message:
M(step)];
  
    [displayActions createActionTo: voterDisplay         message:
M(display)];
    [displayActions createActionTo: policyDisplay          message:
M(display)];
    [displayActions createActionTo: proposalDisplay       message:
M(display)];

    [displayActions createActionTo: worldRaster         message:
M(drawSelf)];
    [displayActions createActionTo: proposalRaster       message:
M(drawSelf)];

Suppose that earlier in the code I created lists, a "rasterList", a
"Object2dList" and a "graphList" and add the above objects to them. 
Then is there any reason it would not work to rewrite the codesnippit
as:

        displayActions = [ActionGroup create: [self getZone]];
   
    [displayActions createActionForEach: graphList     message:
M(step)];
    [displayActions createActionForEach: Object2dList     message:
M(display)];
    [displayActions createActionForEach: rasterList     message:
M(drawSelf)];
