Exception when updating multiple zones

[Magnus Kvalheim]

Thanks for making this module - think it can be quite useful for us.

I get an exception when trying to update multiple zones with ajaxResponseRenderer.

Example:
ajaxResponseRenderer.addRender("bookshelfActionZone", _bookshelfActionZone.getBody()).addRender("bookshelfZone", _bookshelfZone.getBody());

Perhaps there is no 'root' node in this case:

Here is the trace.

Looks like you may be right. I have not tested it with multiple zones. I'll take a look this weekend.
