I have several domains where I have successfully created devices and provisioned phones.  Today I tried to create a device in a new domain.  After created the device and saved it successfully, it did not appear in a list.  I thought I made some kind of error so I repeated the device creation and this time it came back with a duplicate device error.  I tried adding a new device in a domain where I have already created devices and get the same thing.  The only thing I have done before that was create a new user group for the domain I was working in and added a user in the group and set the permissions for that user.  Since then I have deleted those entries but it didn't help.  How can I troubleshoot this?  This ever happen to anyone else?
