Problem

Trying to add a new hostname (field) to a host (object) in Composer the following error is thrown:

Unknown error: SQL error: RemoteException occurred in server thread: nested exception is:

java.rmi.RemoteException:null, nested exception is:

com.sopra.framework.data.DataException

Resolution

* Create a new object

* Move all objects (servers) to the new one.
* Bring back to design existing ones (which are sent to server): pay attention that some servers have to be stopped, so this actions is qualifying for service window (Production maintenance Stop)

* Send new host (objects) to server.
