In a MSSQL model, when I create a domain that is of a type “UniqueIdentifier”, and I then use that in a table, I cannot set the “Row GUID Column” flag. This is only an issue with 5.3. In the older 4.3 it worked fine.
Please fix, this is a very important thing that we must do in a large model we are working on for a new project. The work around is to change the fields from using a Domain to just a standard data type, but that is not ideal.
