Using the code below I am able to create an array collection and set
it as the provider of a datagrid (the resort the columns to match
the way I want them to display).
Now I have two issues I need to solve if anyone is able to help:
1) I have of defined static arrays (mynewArray1 - 3) to add to the
array collection and I need these to be dynamic (mynewArray[0] - n)
2) When I use myArrayCol.addItem({Name:...) I need to build this
dynamically since the field names will be dynamic. I'd like to use
the mycolNames array instead. As an example myArrayCol.addItem
({mycolNames[0]:mynewArray[n][z]}
Here is the code:

myArrayCol.addItem({Name:mynewArray1[z], Count:mynewArray2[z],
TFBool:mynewArray3[z]});
}
myDG.dataProvider = myArrayCol;
for (var y:int = 0; y < myDG.columns.length; y++) {
myDG.columns[y].dataField = mycolNames[y];
}
}

I hope I'm being clear... I need to add an unknown number of columns
to the ArrayCollection so I can't manually define it in the mxml.
I'll be looping through a set of user choices and building the array
collection based on those choices.
Please help!
