Binding null values

[abstraction]

I'm trying to use the BindingManager to bind a null value to a decimal? property. Is this currently possible or do I need write a TypeConverter?

For reference here's the error I get when attempting to bind the null value to a decimal?.


Cannot convert property value of type [null] to required type [System.Nullable`1[[System.Decimal, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]] for property 'MyDecimalProperty'.

Hi,

are you using the latest nightly build? There's a JIRA issue SPRNET-408 (http://opensource.atlassian.com/projects/spring/browse/SPRNET-408) about this problem but it says it is already resolved.

cheers,
Erich

I'm using the Spring.Data.NHibernate12-20070412-0201.zip, which is the latest Spring.Data.NHibernate12 build. Is this build sufficient?

I believe these are the relevant bits. Let me know if you need anything else.


using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;

namespace My.Model
{
[Serializable]
public class Application
{
private decimal? credits;

public virtual decimal? Credits
{
get { return credits; }
set { credits = value; }
}
}
}



protected override void InitializeDataBindings()
{
BindingManager.AddBinding("credits.Text", "application.Credits");
}
