Max and I were having trouble getting our flex project synced up with flex. It kept throwing errors, like:

Error: Error while performing action: Can't copy '/Volumes/Files/Project/Assets/Wireframe/bin-debug/.svn/text-base/index.template.html.svn-base' to '/Volumes/Files/Project/Assets/Wireframe/bin-debug/.svn/tmp/index.template.html.tmp.tmp': No such file or directory

Finally we decided we need to just ignore the bin folders. That stuff gets autogenerated all the time by flex, so I think it’s a reasonable solution. This article has some related info, but it’s for Flex 2 and I don’t think it applies directly. For now I’m just doing the bin folders and seeing if that’s enough to stop the svn errors.
