Summary: You have to remove all flex/flash dependencies from your AS3 code and you have to replace your mx/spark components by FlexJS components. Depending on your code base that could be more or less work. All pure AS3 code without any dependencies to flex/flash should work out of the box with FlexJS. A flex/flash dependency could be identified by imports that start with e.g. flash, spark or mx... e.g.: import mx.collections.ArrayCollection; Hope this helps, Olaf -- View this message in context: http://apache-flex-development.2333347.n4.nabble.com/Is-it-possible-to-Convert-Flex-Application-to-HTML5-tp62212p62224.html Sent from the Apache Flex Development mailing list archive at Nabble.com.
