That sounds like another problem of initializing things out of order. Initialize elements from the inner-most plugin to the outer-most plugin, ensuring that when you initialize a plugin, it is completely visible on the page prior to initialization.
For example,
<tabs><!--- Fifth --->
<ul></ul>
<tabcontent>
<accordion> <!--- Fourth --->
<chosen> <!--- Third --->
<accordion> <!--- Second --->
<accordion></accordion> <!--- First --->
</accordion>
</chosen>
</accordion>
</tabcontent>
</tabs>
consider the toggler as an accordion. you want to initialize everything within it before you initialize it.
