Cannot handle the request because a modal dialog or alert is active

[McShaman]

I cannot work out for the life of me why I am getting this message when 'Cannot handle the request because a modal dialog or alert is active'. I have simplified my code down to replicate the issue.

All I want to do is have a dialog box that allows me to modify elements on the page... But it does not seem to allow it. I must be missing something simple.

var selection = app.activeDocument.selection[0];

dialog = new Window('dialog');

var button = dialog.add('button', undefined, 'Resize');

  button.onClick = function() {

  selection.geometricBounds = [0, 0, 10, 10];

};

dialog.show();

Use 'palette' instead of 'dialog' and place '#targetengine "session";' this line at the top of your script.

So you cant use a dialog to do this? Also I tried using a Palette... But I keep haveing this issue where the ballet is behind the main indesign window... So you cant see anything. Do you know how I can fix that?

did you used '#targetengine "session";' as Chinna said? i tried and it is working fine

If you use "dialog", then you have to quit the modal state to interact with the app. Thta's done by closing the dialog.

var w = new Window('dialog');
var v = w.add ('edittext');
var b = w.add('button');
b.onClick = function(){
    w.close(1);
}
if (w.show()==1) alert (v.text);

Or switch to mom modal dialogs as otherly suggested...
