How do I loop through AFrames?

Question

I feel dumb asking this but I really think the code I have should work. All I want to do is loop through all the aframes in a document. To do this, I assign the first Aframe to a variabe named vAFrame. Then, I created a while loop where the test is vAFrame.ObjectValid(). however, the while loop never tests to true even though the data browsers shows that the vAFrame variable contains a valid object AND it supports the ObjectValid() method AND the valid object is an AFrame. I must be missing something really obvious here. Any ideas?
main ()
function main()
    var vDoc=app.ActiveDoc;
    var vFlow=vDoc.MainFlowInDoc;
    var vTextFrame=vFlow.FirstTextFrameInFlow;
    var vAFrame=vTextFrame.FirstAFrame;
    while (vAFrame.ObjectValid())
        vAFrame=vAFrame.NextAFrame;

I am heads down on a project so I can't give you much code right now, but I can point you in the right direction. The method you are using only works for a single text frame, so you would also have to include a loop for all of the text frames in the flow. A better approach is to get a list of FrameAnchor items from the main flow of the document. Then you can loop through the text items to process each anchored frame.
// Set a variable for the main flow in the document.
var flow = doc.MainFlowInDoc;
// Get a list of the anchored frames in the flow.
var textItems = flow.GetText(Constants.FTI_FrameAnchor);
// Loop through the anchored frames.
for (var i = 0; i < textItems.len; i += 1) {
  var aFrame = textItems[i].obj;
  // Do something with the anchored frame here.
Note that this will only get anchored frames in the main flow itself; it will skip anchored frames that are inside table cells or nested in other anchored frames. Please let me know if you have any questions or comments.
