If you try to add an object out of an linkagename in Flex you get errors. Like:  
1180: Call to a possibly undefined method [linkage name].

If I don’t want to create classes for every library symbol I’d like to add, is there any other way/praxis of doing this besides using ‘getDefinitionByName’, so that I won’t get errors in Flex?
