There are too many errors for me to take the time to address each one. I am going to provide some information that you will have to combine with your knowledge of Flex to have the greatest impact on the number of errors, then we can discuss the leftover harder cases. First, all of your MXML files need to converted like the main app. You have to change the mx namespace URI and add the fx namespace URI and convert some tags like Style, Script, and Metadata to fx. Some issues, like the CSS and States is due to differences between Flex 3 and Flex 4. Here is the documentation on the differences: https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/upgrading-flex3-to-flex4-techguide.pdf Problems like "import flash" should be described in the Royale documentation. Flex and Royale are designed to be a layer above the Flash runtime so it should have been possible to write a Flex app without ever writing "import flash". Royale is emulating Flex, not Flash, so where your code uses "import flash", you will have to find a replacement for it. Many things have been emulated in mx packages like mx.net.FileReference, but not everything (at least not yet) so your team will have to consider how important that Flash feature was and what expense you want to go to in order to get it to work again. Another group of errors is due to the fact that the JS runtime does not support weak reference listeners. Many times weak reference listeners were not actually needed so your team will have to consider each usage and decide what to do. If you think you really need weak reference listeners then describe the scenario in a separate issue. Another group of errors is because Royale does not currently have an emulation for Flash's Dictionary. Many times it also isn't needed. If you are not using weak-reference Dictionaries then you can often use an Object if the toString() is unique. Another group of errors is because DisplayObject is no longer the lowest level visual element. Try using IUIComponent, UIComponent, or IFlexDisplayObject. Another group is use of getTimer(). You could replace it with `Date.now()`. There is a `getDefinitionByName` in `org.apache.royale.reflection`. Make these changes and see what's left. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
