$item was passed in by reference; should it not be passed by reference here as well?
public function populateObjects(&$item)
	{
		if (!empty($item->params) && is_string($item->params))
		{
			$registry = new JRegistry;
			$registry->loadString($item->params);
			$item->params = $registry->toObject();
		}
	
		parent::populateObjects($item);
	}
parent::populateObjects(&$item);

If you do that, PHP5 will throw a big error.

No, it is deprecated and finished this this when you use the '&' in the call. Only for arrays, and only for declarations of the parameters of the function.
All objects are pointer, so only simple vars and arrays need that. but only in the parameters declaration.

Even here in our case, I am not sure if it is required in the declaration. It is just a coding style for the coder to remember it is a OUTPUT parameter.
But when $item is an object, you can be sure it will be working even without '&' because it is systematically a pointer.
Coding is now a piece of cake

I must say that I'm leaps and bounds ahead of where I would have other been with J2.5 with full thanks to the folks on this forum and specifically to Cook so you'll never hear me complaining.
