Flex 3: Using array item value as an objects name

If I have a list of items in an array that represent the names of modules:

var phaseNames:Array = new Array("directorsPrep", "checkIO", "pickupPhoto", "pickupPhoto", "syncing", "dailies", "pictureEdit", "soundEdit", "soundMix", "colorCorrection", "finishing");

and I want to go through each one of these and call a function within each instance of each module, how would I go about doing so. So far, I have the following:

private function changeStartViewDate(numDays:Number):void
{
    startViewDate = rightDate(startViewDate.getMonth(), startViewDate.getDate() + numDays, startViewDate.getFullYear());
    getDateInfo();
    determineCalendarWeek();
    var phaseNames:Array = new Array("directorsPrep", "checkIO", "pickupPhoto", "pickupPhoto", "syncing", "dailies", "pictureEdit", "soundEdit", "soundMix", "colorCorrection", "finishing");

    for (var i:int = 0; i < wholeProject.length; i++)
    {
        wholeProject[i].moveProject(Number((1-2) * numDays));
    }
    for (i = 0; i < phaseNames.length; i++)
    {
        for (var j:int = 0; j < [phaseNames[i]].length; j++)
        {
            [phaseNames[i]].movePhase(Number((-1) * numDays));
        }
    }
}

But when I try to save it, I get the following error:

1084: Syntax Error: expecting identifier before dot.

It's telling me the error is on the following line:

[phaseNames[i]].movePhase(Number((-1) * numDays));

I tried doing something like the following, but it didn't work:

[phaseNames[i].movePhase(Number((-1) * numDays))];

The above attempt of trying to figure this out gave me the following error

1064: Invalid metadata.

Any help would be appreciated.

I am going to assume that:

  1. Each value of your phaseNames array references an actual instance of some other class [and not the name of the class]
  2. The instance defined in the phaseNames array is a child of the current class.

You should be able to do something like this:

var childName = phaseNames[0];
var myChild : myObjectType = this[childName];
// then call function
myChild.doStuff();

This approach is not dissimilar to what you have; I'm just doing it in more lines. I'm also adding the this keyword to access the child.

I bet if you tried this, directly, it would work:

this[phaseNames[i]].movePhase(Number((-1) * numDays));

I have to wonder why you haven't created an array of all the instances instead of an array of all the variables names that point to the instances.
