Your class isn't being linked in, because it isn't referenced. Your options are: (a) force it to be linked in, either with an explicit reference, or via a compiler flag. (b) make sure that the code below is in a SWF is loaded into (or as a child of) an ApplicationDomain containing your class. (c) dynamically load another SWF that contains the definition, and use ApplicationDomain.getDefinition. -rg

I get the class name as a String in Flex code and then I have applied the below code to instantiate that string as a class. Here "MyClass" is a custom class inside the "com.apps" package. I have also imported the above class with fully qualified name. I have a code written as below: try { var dynamicClass: String = "com.apps.MyClass"; var classRef:Class = flash.utils. getDefinitionByN ame(dynamicClass ) as Class; var myClass:* = new classRef(); } catch(e:ReferenceEr ror) { tracer.traceMe( e.errorID + " "+e.message); } This code works perfectly with the standard Flex classes like "flash.display. MovieClip" but gives me Reference error (code 1065) when I use "com.apps.MyClass" for the dynamicClass statement above. Anything specific needed to be done with the custom class, to make it accessible, the way MovieClip class is accessed. Any ideas of how do i go about this? Amol.
