2128053 - Preview of models does not work

There are unspecific issues with models stored in shared repository:

• Synchronizing them is not possible. It fails with an unspecific error
• They can be deployed but when trying to preview a model an internal server error "Application error occured during the request processing." is shown
  
  The default trace contains the following error:
  
  "... Caused by: com.sap.tc.webdynpro.services.sal.core.DispatcherException: The requested deployable object is not deployed on the server. Please check the used URL for typos."
  "... Caused by: com.sap.tc.webdynpro.service.exceptions.WDRuntimeException: Failed to create deployable object since it is not a Web Dynpro object.
