A quick tip - how do you change the text of a window created by CFWINDOW? All you need to do is grab the underlying window object:

var win = ColdFusion.Window.getWindowObject("mywin");

In this object there is a body property which is a complex structure pointing to the body of the window. I thought perhaps the body was a simple string. I did:

win.body = 'Chicago better not be too cold';

Which didn't work (nor did it throw an error). Then I used ColdFusion's Ajax debugger:

ColdFusion.Log.dump(win.body);

This revealed the entire body element and I saw that there was a dom key which pointed to the DOM object. So all together now - the code is:

var win = ColdFusion.Window.getWindowObject("mywin"); win.body.dom.innerHTML = "Hi Ray, how are you?";

And there is a complete template for you to try:

<script> function test() { var win = ColdFusion.Window.getWindowObject("mywin"); win.body.dom.innerHTML = "Hi Ray, how are you?"; } </script>

<cfwindow name="mywin" width="400" height="400" closable="true" initShow="true" title="Test"> Initial Content </cfwindow>

<form> <input type="button" onClick="test()" value="test"> </form>

Edit: Please be sure to read Todd's comment below. There is a simpler way to do what I did above. I'd nuke my own entry - but I figure the alternative I used would still be of interest to folks.
