Cannot create Workspaces (CM is installed on two Site Collections or more)

Cannot create Workspaces (CM is installed on two Site Collections or more)

Problem:

When you create a workspace you are getting an Error. In the log there is an entry like "... invalid field name ..."

Reason:

You have installed the Collaboration Manager on two Site Collections or more. The settings for the CM are global, so the Field of the URL must be clearly.
 

Solution:

With two or more installed CMs you must set the field as "Title" instead of "ID". You can do this in the CM-Setup ->Setup ->  Settings -> Basic Settings -> Settings for Workspaces
