Hey there,
this information in the docs is slightly out of date, I'm afraid, my apologies for this.
Since a while it is requried to add the stage processor explicitly, that way people can choose to completely ignore stage processing.
You can add the DefaultAutowiringStageProcessor manually like this:
Code:
var processor:DefaultAutowiringStageProcessor = new DefaultAutowiringStageProcessor(applicationContext);
FlexStageProcessorRegistry.getInstance().registerStageProcessor("autowirer", processor, processor.objectSelector);
Hope that helps,
cheers,
Roland
