An internal error occurred during: "Rebuild project".
Attempted to beginRule: R/, does not match outer scope rule: P/gExplorer
I'm not sure what exactly this error is referring to, but it appears when I attemt to build the project or clean the project. It doesn't prevent me from seeing changes in my project though.
I encounter the same problem. It occurs only when my flex project is shared with MercurialEclipse, and everytime I save a file !
If I stop sharing my project, no errors.
If I share the project, and disable the Flex builder (in the "Builders" project properties panel), no errors.
The old Flex Builder 3 works fine, even with MercurialEclipse
I've attached my project.
Thank you in advance !
