As a point of order, the bug with nullable types may well be a bug, but it is also a bug on our end because the fields are boolean but have not been marked as NOT NULL in the database when they should have been.

Re the exception - that would be a bug.   We do attempt conversion of the DefaultValue when we stuff it into the entity, and Convert.ChangeType is throwing because of the Nullable<Boolean>.   For now, DefaultValue won't work with nullable types other than string.  We'll add this to the defect list.  Thanks for reporting it.]]> Thu, 17 Sep 2009 12:30:54 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1478&PID=5407#5407 Latest Version Generated Code Bug? : Rethe first post - We take whatever... http://www.ideablade.com/forum/forum_posts.asp?TID=1478&PID=5405#5405 Author: kimj

Re the first post - We take whatever is defined in the DefaultValue attribute for the property in the EDMX file, and don't validate its correctness or make it language-specific.  So, if you modify the EDMX to use DefaultValue="false" for these properties the code should generate correctly for C#.

Just saw your second post ...

Also, I am getting this error when I try to run the app:

It seems the generated code has an invalid setting for the DefaultValue for boolean properties in C#:
    [Bindable(true, BindingDirection.TwoWay)]
    [Editable(true)]
    [Display(Name="Promoted", AutoGenerateField=true)]
    [IbVal.ValidateProperty]
    [IbVal.RequiredValueVerifier()]
    [IbCore.DBDataType(typeof(Boolean))]
    [DefaultValue(False)]
    [MsSer.DataMember]
    public Boolean Promoted {
       get { return PromotedEntityProperty.GetValue(this); }
       [global::System.Diagnostics.DebuggerNonUserCode]
       set { PromotedEntityProperty.SetValue(this, value); }
    }

Notice the upper case False. A lower case false works fine. A simple find and replace has fixed it for me. Am I doing something wrong though? Is my mapping file wrong somewhere? Thanks, Simon.]]> Thu, 17 Sep 2009 11:20:29 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1478&PID=5403#5403
