Hi 
- When you create a group and add member and not fill ALL required fields (but for example only 1 of 2 required fills) - there is a error, that you not filled required fields (and that is ok), but when you again click create, group is created without member.
- When i open update view (for group which have for example 1 member) i try to add another member and fill only 1 of 3 required field for new member - when i click save - there is error, that you not filled required fields (and that is ok), but when i again click save i got ERROR 500 - property "“Mymodel.pk_” is not defined.
Can you help me ?
Thanks
Tom
