If your project contains java then clean your deployment directory to get rid of old code that still uses attribute or entities.
During the deployment I got another error about web service in the Mendix Modeler console. this occurred after previous error in the earlier post.
REMARK: we do not have any web service in this model. For the full trace-log please download HERE
