You used Spark Application, which I just got working a few days ago. There might be issues with Alert and other popups in a Spark application.
If you want to learn more about Royale and Emulation, try debugging into it and see what you can figure out. Otherwise, I will look into it after I get the release candidate out for vote. -Alex On 11/13/18, 12:58 AM, "hferreira" <[email protected]> wrote: "Delete the bin/js-debug folder and try again." That did the trick. I need to get used to this new approach since Flex use a single file. The previous compile with the previous Royale SDK probably did this conflite. Now, I can see the button on the screen without console errors however when I press the button nothing happens and I get the following error: Uncaught TypeError: Cannot read property 'systemManager' of undefined at Function.mx.controls.Alert.show (Alert.js:159) at HelloRoyale.$EH0 (HelloRoyale.mxml:12) at Function.goog.events.fireListener [as googFireListener] (events.js:744) at Object.org.apache.royale.core.HTMLElementWrapper.fireListenerOverride [as fireListener] (HTMLElementWrapper.js:61) at HTMLButtonElement.goog.events.handleBrowserEvent_ (events.js:870) at HTMLButtonElement.f (events.js:289) -- Sent from: https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fapache-royale-users.20374.n8.nabble.com%2F&data=02%7C01%7Caharui%40adobe.com%7C6835294e5d49400f104108d649462b80%7Cfa7b1b5a7b34438794aed2c178decee1%7C0%7C0%7C636776963062359756&sdata=Lj1M8bvxrBfOgqzNIy9%2BkjLhwi6FGUBm61WRfGblpy0%3D&reserved=0
