Bug 3248 Creating a new class creates 3 entries in local history (1GE4TOC)
Creating a new class with the class wizard creates 3 entries in the local history. The oldest is empty, the others have the same content. NOTES: EG (5/23/2001 11:35:43 AM) is the wizard setting the contents 3 times? MA (5/25/01 10:10:32 AM) JDOM automatically saves the content 2 times add import: I have to save, otherwise create hierarchy does not succeed. EG (5/30/01 9:43:51 AM) JDOM should provide control over the saving behaviour and not do it automatically. Moving to JCORE for comment.
