"Yes: ActionScript 3 is fundamental." Hi Martin,
While i recommend Flex devs to learn ActionScript. ActionScript is not mandatory to buil Flex applications. Based on a customer request a couple of years ago we create Flex4j (Flex for Java it is) That allows Java developers to write Flex application entirely in Java using GWT (No ActionScript required) A demo can be found here : http://www.gwt4air.appspot.com/ The entire application is written in Java and contains a lot of demos. You can also hit the the source button to see how the code looks like. We opensourced the product sometimes ago http://emitrom.com/gwt4flex and it has been a great success since then.
