I saved the Aplication Node in C:\NXP\bstudio_nxp\workspafe following the BeyondStudio for NXP installation and User Guide (JN-UG-3098)
first I imported the project(JN-AN-1218)

than it should be visable in the project explorer

I get all these yellow ! and I can't open the files. I followed the same path with the JN-AN-1171 and this works just fine.
Do you know what may be cousing the problem? I installed the right SDK for ZigBee 3.0 (JN-SW-4170) before this process.
