Question
Does anyone know of any flex based (preferably open source) framework or component to edit UML? I was looking for something like gliffy.com, however that will not let you export to an XMI file.
Solution 4
After several days of googleing, it looks like what I'm looking for doesn't exist.
OTHER TIPS
We are going to release soon UML4AS - UML for ActionScript and Flex. It supports bi-directional code synchronization for .as and .mxml files.
It doesn't have for the moment an export to XMI option. You could request it as a new feature on our site.
This is one of the Opensource UML Tool which supports XML exporting option. Check it out
It seems to me there are no open source Flex based UML Tools. I think you should build on and open it up to the public.
