$item was passed in by reference; should it not be passed by reference here as well?
public function populateObjects(&$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

Hi first of all I'd like to say that J-Cook is a great tool - the best component builder I tried so far...
