So I went and started a fresh movie to duplicate the problems I
encountered and I 'm finding removeMovieClip does seem to recursively
remove stuff. I 'll have to go back into my application and figure out
where my problem was, but the following works as "expected ". Of course, in the application, all of the movies are more variable-oriented.. not that it should matter.
this.createEmptyMovieClip( "CONTAINER ", 1);
this.CONTAINER.createTextField( "TEXT ", 2, 1,1,1,1);
this.CONTAINER.TEXT.text = "test ";
this.CONTAINER.attachMovie( "Button ", "BUTTON ", 1);
this.CONTAINER.BUTTON._x = 10;
this.CONTAINER.BUTTON._y = 20;
this.CONTAINER.BUTTON.testFunction = function() {
var balogna = 1;
}
this.CONTAINER.BUTTON.testProperty = 1;
trace(this.CONTAINER.BUTTON);
trace(this.CONTAINER.BUTTON.testFunction);
trace(this.CONTAINER.TEXT.text);
this.CONTAINER.removeMovieClip();
trace(this.CONTAINER.BUTTON);
trace(this.CONTAINER.BUTTON.testFunction);
trace(this.CONTAINER.TEXT.text);
