This morning Macromedia announced that it has joined the Eclipse Foundation. The announcement referred to Zorn, the code name for an Eclipse based tool for building Flex powered applications.
Eclipse is also of interest to parts of the ColdFusion community, and CFEclipse has a growing following. I should mention that we’re actively investigating various ways of helping the CF community take advantage of Eclipse. There’s no more information to offer at this stage, but we are on top of this one, and I’ll share whatever I can as soon as I can do so.
