Looks like you are using xmlns:mx=”library://ns.adobe.com/flex/mx”
These need to be changed for Royale to be xmlns:mx=”library://ns.apache.org/royale/mx”
We can’t guarantee that all custom subclasses that worked in Flex will work in Royale. Those that override lifecycle methods (commitProperties, measure, updateDisplayList) will probably need modification to work. createChildren() overrides
should be ok.
