Hello! After a comment on the Adobe OpenSource Wiki (which can be seen here: http://opensource.adobe.com/wiki/display/flexsdk/Targeting+Flash+Player+10+Beta?focusedCommentId=15237175#comment-15237175), I have opened a bug on JIRA (https://bugs.adobe.com/jira/browse/FB-13863) about the failure of the auto-completion system in Flex Builder when using Flash 10 libraries.
To be short, this bug prevents the auto-completion system to access to any class that contains Vector. It prevents these classes to be suggested by the auto-completion, and to be managed by the organize imports feature. This issue can be seen with the workspace attached to the ticket, or simply using the Player 10 class TextBlock (which uses Vector internally). This bug is critical to my project, because it uses many libraries and relies a lot on the auto-completion to accelerate the workflow of my team. We really do want to switch to Astro as soon as possible, but there's really no way we can do that before this issue is fixed. So I wonder, I haven't seen anyone reporting this issue before. Did you ever encountered such problem? If not, what is the configuration you're using? If yes, have you found any workaround? Thank you very much.
