Description martin 2015-10-04 11:42:42 UTC
public static BindableProperty DateProperty =
        BindableProperty.Create<ClassName, DateTime?>(o => o.Date, null, BindingMode.TwoWay, null, OnDateChanged);

        public DateTime? Date
        {
            get { return (DateTime?)GetValue(DateProperty); }
            set
            {
                DateTime? tmp = value;
                SetValue(DateProperty, tmp);
            }
        }

Setting it in the code like 'Date = null;' raises the following error:
SetValue: Can not convert  to type 'System.Nullable`1[System.DateTime]'
[0:] SetValue: Can not convert  to type 'System.Nullable`1[System.DateTime]'
10-04 17:20:34.132 I/mono-stdout( 5246): SetValue: Can not convert  to type 'System.Nullable`1[System.DateTime]'
10-04 17:20:34.136 I/Choreographer( 5246): Skipped 285 frames!  The application may be doing too much work on its main thread.

It can be null at the beginning, but as soon as it has once a Value i can not reset it to null.

Thank you for your help.

Should be fixed in 1.5.2-pre1
