I found your discussion here https://github.com/apache/royale-asjs/issues/495
that talks about having to change your configuration file to be able to use mx components in a Royale app since 0.9.6 was released. So now my test app can see the classes and I thought everything would work. I made a couple of small changes to my code above that were typos, but now I am getting an error on this line PopUpManager.centerPopUp(cityStatePopUp); that says says "Implicit coercion of a value of type CityStatePopUp to an unrelated type mx.core.IFlexDisplayObject" I have run this line of code a million times in AIR, so I don't understand why I am getting this error in Royale. Can anybody give me a suggestion? -- Sent from: http://apache-royale-users.20374.n8.nabble.com/
