Attribute maps broken ?

Question

Hi, CityEngine throws the error below when using mapped attributes. This happens with fresh projects or one of the tutorials (MediEval_City_64Bit in this case). We're running Esri CityEngine 2011.2 build 120125 (trial, linux-64bit) on CentOs 6.1 The .project file of the MediEval project looks like this: Example_Medieval_City__2011_2 org.python.pydev.PyDevBuilder__2011_2 com.procedural.lang.cga.cGABuilder__2011_2 com.procedural.lang.cga.cGABuilder com.procedural.cityengine org.python.pydev.pythonNature org.eclipse.core.internal.resources.ResourceException: Failed to read the project description file (.project) for '.attribute_layer'. The file has been changed on disk, and it now contains invalid information.

Hi !

Answer from our lead dev :

"The �??.attribute_layer�?� project is garbled. One could try to delete the folder in the workspace, but I think creating a new workspace may be more safe. Sure is that the attribute layer code is also stored in the scene ( cej ), so you'll lose nothing."

Hope this helps !

Hmm, I started a new workspace and the problem went away.

You can delete the thread if you like.

PS: I was previously using a symlink for the workspace root, maybe that's got something to do with it?
