We've got an Flex 3 application which I've recently "upgraded" to Flex 4 - mainly by using Flex 3 Compatibilty Mode.The next phase of the application requires loading of a number of custom and configurable modules. To this end, I've been working with ModuleManager to load a module into a container in the main app.
If I try to load in a module - fully Flex 4 SDK with a couple of spark components, I get an error about the skin for one of the components not being found:
Error: Skin for main.appStage.consoleView.consoleareas.Canvas68.admin.VBox409.pluginContainer.MyPlugin.HG roup427.btnPressMe cannot be found.
I appreciate that I cannot load modules of a different SDK version into the app, but is it the case that there are issues trying to load a Flex 4 module into an app compiled in compatibility mode? The module in this case has one s:label and a couple of s:Buttons (the btnPressMe being the first). If I try a module that only has the label, it seems to work fine. I haven't create a specific skin for the btnPressMe component, by the way.
Thanks in advance for any advice with this.
I'm not sure Spark components will work if the compatibility mode is set to
