Could you attach a sample file for which this happens? Thanks. 486582 3 geroxp 2006-11-14 11:25:20 +0000 I have sent an e-mail to your t-online address (I hope it's still valid) with an attachment, because I can't make a testcase at the moment. Now opening the file crashes umbrello and I can't work with it anymore :( 487089 4 okellogg 2006-11-16 06:53:34 +0000 > Now opening the file crashes umbrello and I can't work with it anymore With r604997 at least it doesn't crash anymore. I haven't been able to reproduce the duplications. It would help very much if you could describe the exact steps that you did to get this problem. 487119 5 geroxp 2006-11-16 10:50:18 +0000 Okay, I checked out the latest version in branch. Now, when I load my project all associations are gone. Umbrello gives me: umbrello: ERROR: couldn't loadFromXMI association widget:0x8d77a10, bad XMI file? Deleting from umlview. umbrello: ERROR: AssociationWidget::loadFromXMI: cannot find UMLObject 3187 Repeated about 100 times. Also I get: umbrello: UMLListView::slotObjectCreated([...], id= 16442): item already exists. where [...] is a method-name, this is also repeated about 100 times. I will try to make some test cases within this week and upload them here. Perhaps this is more than one bug. If I feel there are different problems I'll open new bugs. Thanks for paying attention to this issue! 487377 6 okellogg 2006-11-17 01:11:13 +0000 > Okay, I checked out the latest version in branch. > Now, when I load my project all associations are gone. Fixed by r605507. The crash on close resurfaced and is hotfixed by r605508. It's not quite clear to me yet why deleteLater() doesn't crash while calling the destructor directly does - I'll try to further investigate. Thanks for your valuable input Gero. 487909 7 okellogg 2006-11-19 10:13:09 +0000 I am renaming this because the original PR is a duplicate of #129859, and the new title better reflects the actual work done.
