When trying to create a database table, if when adding a column, the 'Has Default Value' checkbox is true, but the 'Default Value' textbox is null, the table create service fails.
In addition, the Composer-side pieces are created, but the database table is not. This requires manually cleaning up the Composer-side entities that are generated.
Expected Behavior: The popup should disable the 'Add Column' button in the UI if 'Has Default Value' is true, and 'Default Value' textbox is null.
