Migrating application to flex sdk 4.5

Hi all,

I just migrated Flex AIR application from SDK 4.1 to 4.5, and instantaneoulsy after building, the Flash Builder V4.0.1 started throwing random errors. The errors make no sense at all. The errors I get are:

identifier 'someID' used more than once..., even though I have not used these ids more than once. Also, I get hundreds of these. And they don't disappear after cleaning or restarting.

What is even more strange is these errors persist even when I swicth back to SDK 4.1. I have to manually remove 4.5SDK from the configuration list, and have 4.1 as my default SDK. This is very odd! Not sure where to look at!

I am using Mac OS X 10.6 with Flash Builder 4.0.1. Please let me know how to fix these errors.

Thanks!

I had the same issue, something with the project settings files most likely. Easiest way to fix the issue was to create a new Flex project in FB 4.5, then copy all your source code back into the new project. You may also be able to remove the ".x" project files at the root our your project and re-add the flex nature to solve the issue instead, but I just did the former.
