[Mono-aspnet-list] Nhibernate3: Failed to convert parameters

[Antoine Cailliau]

Dear all,

(I'm not sure the error is due to NHibernate and not to mono. This cause 
double posting: here and on nhibernate forum.)

I setup a small web application to test nHibernate with mono and 
postgresql.

I'm facing a problem I can't find a solution. Nhibernate throws an 
"ArgumentException" with message "failed to convert parameters".

Here is the stack trace:

System.ArgumentException: failed to convert parameters
   at System.Reflection.MonoMethod.Invoke (System.Object obj, 
BindingFlags invokeAttr, System.Reflection.Binder binder, 
System.Object[] parameters, System.Globalization.CultureInfo culture) 
[0x00000] in <filename unknown>:0
   at System.Reflection.MonoProperty.SetValue (System.Object obj, 
System.Object value, BindingFlags invokeAttr, System.Reflection.Binder 
binder, System.Object[] index, System.Globalization.CultureInfo culture) 
[0x00000] in <filename unknown>:0
   at System.Reflection.PropertyInfo.SetValue (System.Object obj, 
System.Object value, System.Object[] index) [0x00000] in <filename 
unknown>:0
   at NHibernate.Properties.BasicPropertyAccessor+BasicSetter.Set 
(System.Object target, System.Object value) [0x00000] in <filename 
unknown>:0

My project is a very simple ASP.NET MVC. The error shows up when I do 
session.save:

Product p = new Product { Name = "Cool", Id = 0 };
session.Save(p);
tx.Commit();

Product is defined as:

public class Product
{
	public virtual int Id { get ; set ; }
	public virtual string Name { get ; set ; }
}

With the mapping

<class name="Product">
   <id name="Id">
     <generator class="counter" />
   </id>
   <property name="Name" />
</class>

The table is correctly created.

create table Product (
   Id int4 not null,
   Name varchar(255),
   primary key (Id)
)

Any idea on why I'm getting this error?

Thanks in advance for your help !

Antoine
