Error #1034: Type Coercion failed: cannot convert mx.graphics::Stroke to mx.graphics.IStroke.
This turned out to be a pretty haunting bug, and I still don’t quite understand what I did to fix it, but I did.
You’ve probably already seen the Adobe Bug SDK-9480
And of couse you’ve seen an error that looks like so…..
TypeError: Error #1034: Type Coercion failed: cannot convert mx.graphics::Stroke@dfd3e21 to mx.graphics.IStroke.

The situation only appears to occur when I am running a Module across Application Domains. For me it worked fine, as I was developing the module stand alone with a Main.mxml that I was using as my loader for the Module. When I ported the module to my global application….I was not so lucky and it broke things.
To fix the bug you will need to make a change in the code that is loading the module. In 1 of the following 2 ways. I used the 2nd because forcing all modules into the same “currentDomain” broke other modules that were using shared classes.
Here are the 2 ways I know of to fix it.
1) Set the Application Domain in your ModuleLoader as follows
var Mod:ModuleLoader = new ModuleLoader();
Mod.applicationDomain = ApplicationDomain.currentDomain;
2) In your Parent Application not in the module itself. (Every module needs and application)
import mx.graphics.IStroke;
private var uStroke:IStroke;
Really appreciate your post.
Your second option works for me.
Thank you
