Hi Liju, I posted a reply earlier, but maybe you are having subscription problems.
Are you migrating a Flex 3 application? If so, then yes, the xmlns have to be changed to look like this: xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:mx="library://ns.apache.org/royale/mx" And you may need to add the compiler option: +configname=flex Note the "+" instead of "-".
