Typescript generated file display problem in Project Window

Hi,

I got a problem on display typescript files in Project window. i am working with typescript plugin and filewatcher. It will generate js and js.map files for ts files.

Normally, it display generated js and js.map in a sub tree in the .ts file. But now some js and js.map file is display outside. Delete the gerenated file and try again, it still not solve.
