oop - added Children but objects not displaying in Flash -

i'm adding series of objects dynamically flash movie xml won't appear when run movie. have identical code adding objects in different swf works fine. have tested 8 ways sunday including ensuring added container child of main movieclip (tested display list), added stage (had listener added_to_stage) , position correct (displayed x,y values , compared them mousex & mousey values). in correct place in display list. still there no objects. class linked correctly, have movie clips in library.

any ideas causing problem? feel i've checked everything.

'public class minimap extends movieclip {

have used addchild() command once object have been loaded flash? need add objects display list them show on stage (assuming coding in as3)
