Current results:

The type information is missing in the generic type definition:

C#
parameter2.Type = typeof(global::DevExpress.DataAccess.Expression);
parameter2.Value = new DevExpress.DataAccess.Expression("?parameter1", typeof(System.Nullable<>));
this.objectDataSource1.Parameters.AddRange(new DevExpress.DataAccess.ObjectBinding.Parameter[] {
parameter2});

Expected results:

C#
parameter2.Type = typeof(global::DevExpress.DataAccess.Expression);
parameter2.Value = new DevExpress.DataAccess.Expression("?parameter1", typeof(System.Nullable<**DateOnly**>));
this.objectDataSource1.Parameters.AddRange(new DevExpress.DataAccess.ObjectBinding.Parameter[] {
parameter2});
