Alex this might be a question more for you, unless others are familiar with the topic.
I am currently doing a bit more on reflection. Instead of outputting the fully resolved ancestral definition for each class, which would mean a lot of duplicated output across the inheritance chain, I assumed it would be best to resolve this at runtime (with caching) in the TypeDefinitions. So each TypeDefinition lookup would check its ancestors and add to its local collection of instance based members if they weren't already 'declaredBy' again (an override), and I envisaged caching the fully resolved TypeDefinition. This would get to a similar result to flash native describeType. so I am adding inheritsFrom into the output like so: MyInitialView.prototype.FLEXJS_REFLECTION_INFO = function () { return { inheritsFrom: function () { return [ 'org.apache.flex.core.View', 'org.apache.flex.core.ViewBase', 'org.apache.flex.core.ContainerBase', 'org.apache.flex.core.UIBase', 'org.apache.flex.core.HTMLElementWrapper', 'flash.display.Sprite', 'flash.display.DisplayObjectContainer', 'flash.display.InteractiveObject', 'flash.display.DisplayObject', 'flash.events.EventDispatcher', 'Object' ] ; }, But it seems that the framework swc library only provides the flash version of the inheritance chain for this, because jx sees the flash.display.* classes in the loaded typedefinitions. Is there any way the compiler can load the definitions that were used when the js part of the swc was compiled for jx? I suspect not at the moment, but I'm just checking that I am not missing something obvious.....
