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.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.
