Can't access IFRAME Content in window

I am using 2.6 Pro and attaching a URL to a window. The page loads fine. In the onClose function I want to access data on the page loaded in the window to update the calling page. However after much searching through the offline and online documentation I still can’t access the IFRAME.

dhxWins.window(“win”).getFrame() object doesn’t support this property or method
dhxWins.window(“win”)._frame undefined

Try to use attached dhtmlxcontainer.js. Possibly the library from your package doesn’t contain getFrame() method.

Thanks Alexander
I’ve got it working with that.
