To instantiate classes via a string I do the folowing:
I have a class Popups.as:
class Popups
{
public function Popups()
{
package.className1;
package.className2;
package.className3;
};
};
The above class makes sure the classes are included in the swf.
Then when I need to access it I can do things like:
var classString = "package.className3";
var classRef = _global;
var class_array = classString.split(".");
for (var i = 0; i < class_array.length; i++)
{
classRef = classRef[class_array[i]];
};
Then u can use classRef to do whatever u want.

Actually that's what UIObject does internally. It does attachMovie() on
the class's symbolName. So, yes, it's possible to create an object from
a string identifying the class. Using the class reference seems to be
the preferred way in Flex.
If all you have is strings, you can create a mapping from the strings to
their corresponding class references and look up the mapping every time
you need a reference. Maybe there's a better Flash Way (TM) that I'm
not aware of (some sibling of Object.registerClass() ).
