Hi, in 2.11 when I define a table and I put nothing in Default, all goes well.
In 3.0-dev, the Default dropdown is set to "user-defined" which causes problems for some field types, so I suggest to put "none" there by default, to mimic 2.11 behavior. Otherwise we have to plan all possible field types and a correct default value for each, like is done for VARCHAR (an empty string).
