[news.eclipse.technology.epf] Re: Migration to newever library version

["Peter Haumer" <phaumer@xxxxxxxxxx>]

Hello.
You cannot load multiple versions of the same plugin into the same library. 
All library elements are identified by global unique ids and hence such ids 
needs to be unique.  To get more than one copy of an element you need to use 
the copy operation in the library view. In general we recommend to use a 
version control system like Rational ClearCase which allows you to label and 
restore old versions of whole groups of files.

Best regards,
Peter.

P.S.: Surely they should not be an exception when loading the same content 
twice, but an error message.  Please, file a bugzilla with reproducible 
steps.
