Hello! Thank you for a great post. I use this association method in all my Flash/Flex projects and it worked flawlessly until now .

The concern is that I have three projects which share same classes. So I created Flex-library-project and placed classes to share into it’s packages structure. Then I created three project interested in those classes from Flex-library-project, pointed that Flex-library-project in Projects properties->ActionScript Build Path->Library path->Add project dialogue. Now I have classes visible and can create them like:

package {
import flash.display.Sprite;
public class TestProject extends Sprite {
public function TestProject() {
var pItem:TestSprite = new TestSprite();
addChild(pItem);
}
}
}

package {
import flash.display.MovieClip;
import flash.display.Sprite;

[Embed(source='editor.swf', symbol='MarkerState')]
public class TestSprite extends Sprite{

public var box:MovieClip;
public function TestSprite() {
}
}
}
The problem is that there’s no “box” movieclip in TestSprite I addChild in my main project from the library project. Everything worked fine until I moved TestSprite to that Flex Library Project.
Haven’t found the answer even after hours of heavy goggling around.
Please advice.

Hi.
I have already associtated the symbol with the class I use in the embedding swf. So when I try to export the library.swf Flash complains:exception during transcoding: lib_shell.swf (The process cannot access the file because another process uses it). That is why the embed tag is also recognized by Flash.. problem! How can I make Flash ignore the embed tag?

Hello and thank you for your post, of all those related to this issue, it is the one I like the most.

Do you think you could post or email me an example including the source code and the movie to produce library.swf?

I am asking because I have tried many different combinations and I cannot make this work.

It would be great if you could post or email me a zip file with everything needed.

Thanks.

Thank you, this is incredibly useful!

@Seb: In case you never got it working: I got the same error and fixed it by declaring the movieclip as a variable, like public var myMask:MovieClip; in the class.

Thanks for this tip Mark, I am having the following issue:

My movieclip makes use of other movieclips in the library.swf (like buttons, etc), when I try to complie my “application.swf” I get an error for each movieclip that the Star class references, saying:

1120: Access of undefined property myMask.

My Star class has a line in the constructor that reads:

myMask.cacheAsBitmap = true;

Would you happen to know why this happens? Thanks in advance for your support
