As many of you trying out the Flex Addon have discovered, the current milestone release (1.0.0.M1) is only compatible with Spring Roo 1.1.0.M1 and STS 2.3.3.M1. It does not work with later releases of Roo, up to and including the final 1.1.0.RELEASE.
As of Nov 17th's nightly build (which you can obtain here: http://s3browse.springsource.com/bro...UILD-SNAPSHOT/), the Flex Addon has been tested and confirmed to be compatible with Spring Roo 1.1.0.RELEASE and STS 2.5.1
Further changes were required to bring the addon into line with Spring Roo 1.1.1.RELEASE. These changes are available as of tonight's snapshot (http://maven.springframework.org/sna...075648-225.jar) and going forward. Many thanks to Thomas Fowler for supplying a patch that served as the foundation for this update.
