            Bug ID: 384494
           Summary: Umbrello ER model prevents using names of deleted
                    entities
           Product: umbrello
           Version: unspecified
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: critical
          Priority: NOR
         Component: general
          Assignee: umbrello-devel at kde.org

  Target Milestone: ---

Created attachment 107754
  --> https://bugs.kde.org/attachment.cgi?id=107754&action=edit
xmi file with deleted and therefore unreachable entities inside

Umbrello version 2.23.1 for Windows (Windows 8)

When you create an entity and then deletes it, then there is no way you can
create another entity with the same name as the deleted one.

It shows the error message: "That name is already being used".

Inside the xmi structure it saves the deleted entities, but there is no way to
tell Umbrello to remove them completely.

I guess this bug is related to the way Umbrello handles the UNDO-chain.

In the attachment the entities "Lista2", "NuevaLista" and "MapaProducto" are
deleted entities that still exist but can not be reached within Umbrello.
