After looking how the compiler generates MXML states as suggested by Alex I've discovered some important details...
Let's say that I have these two UI component in my main UI. <serviceloader:UIService id="marketplace" purpose="marketplace" width="100%" height="100%" bottom="0" includeIn="marketplace"/> <serviceloader:UIService id="editor" purpose="timeline" width="100%" height="35%" bottom="0" includeIn="editor"/> The class that is generated automatically is this: https://pastebin.com/dg93hAQv As you can see also the class has this annotation [DynamicStateHost(name="multiverses")] I decided to remove all the states from the main UI to generate them automatically. I my DynamicStateHandler class that is generating the states automatically there is the coded inspired by the MXML compiler. I am able to achieve almost anything except the part where the compiler adds the getter/setter for the Bindings from line 83 to 119. Naturally when my state handler try to set the current state of the main UI to the default one : https://pastebin.com/3Y3C7Fi8 I get this error: Property editor not found on MultiversesMainUI and there is no default value. at mx.states::OverrideBase/getOverrideContext()[D:\flex_sdk\Sources\flex-sdk\frameworks\projects\framework\src\mx\states\OverrideBase.as:151] Does anyone has an idea how to fix this? I've created a dynamic class which extends from Module and used that instead but it doesn't work neither. Right now I have no clue how to bypass this constraint. Best regards Ergü
