Accordion Auto Resize Height with Dynamic Page Size

Accordion Auto Resize Height with Dynamic Page Size

jQuery UI has been great, but I am having an issue with the Accordion height control:
 
I am working on a dynamically resizing page.  I will be placing the Accordion next to a media player that will resize with the page.  Because I need to maintain the aspect ratio, the width must be adjusted along with the height.  I need the Accordion height to match.  I have written javascript expressions to do this, but it is not working with the jQuery UI plugin.
 
I set the expression to resize the div containing the Accordion and set autoFill to true.  This works on page load, but does not resize if the page size is adjusted after (unless it is refreshed).
 
I was starting to try some work-arounds, but I thought there may be some simple solution that I am missing.
 
Any help?  Thanks in advance.
