The switch titled "Enable Flex Data Management Support" in the ColdFusion MX Administrator under Flex Integration menu is automatically enabled in CFMX 7.02. When installing on IBM WebSphere Application Server on Windows, this switch may produce an error when starting such as:

view plain print about
1Unable to initialize FlexAssembler service: coldfusion.server.ServiceException:
2Unable to register Flex Assembler Service in RMI registry: java.rmi.ServerException:
3RemoteException occurred in server thread; nested exception is:     
4java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: no protocol:
6Files/WebSphere/installedApps/server1/ColdFusionMX7.ear/ColdFusionMX7.war/ WEB-INF/cfusion/lib/ant-launcher.jar.

Notice the last line after the that begins with "Files/WebSphere/installedApps/...". Since WebSphere installs by default into "C:Program FilesWebSphere" on Windows, the space in Program Files triggers the error when attempting to enable Flex Data Management support.

A workaround for this is to redeploy the ColdFusion MX 7.02 EAR such that you select a "Directory to Install Application" that has no spaces, and that you remove the spaces in the Application Name "Macromedia ColdFusion MX" to form just "MacromediaColdFusionMX", or choose any other alphanumeric name of your choice.
