724608 - unable to serialize/deserialize custom class across workers

Status: RESOLVED WONTFIX

(Tamarin Graveyard :: Workers, defect)

Description

[Dan Schaffer]

Not able to pass a user written class with flash.net.registerClassAlias or Worker.registerClassAlias across workers.  When the object gets passed back the object returns as Object and (result is Myclass) returns false. 

flash.net.registerClassAlias("Myclass",Myclass);
var myclass:Myclass=new Myclass();
print(myclass is Myclass); // returns true
promise=remote.echo(myclass); // call remote method to worker
var result=promise.receive();
print(result is Myclass); // returns false


I also tried with Worker.registerClassAllias and got the same results.

marking not a bug.  The background worker must also call flash.net.registerClassAlias.  the test works after moving flash.net.registerClassAlias out of the isPrimordial code.
