We are on nhibernate 1.2 and have been able to implement our own
custom list collections but when we tried to implement a custom
dictionary collection we get the following error:
"Unknown entity class: System.Collections.Generic.KeyValuePair`2
I debugged into it and found when using a custom dictionary it uses
the base CollectionType class for the dictionary collection and the
framework ends up call this method in this class:
public virtual ICollection GetElementsCollection(object collection)
{
return ((ICollection) collection);
}
I then debugged it using the standard dictionary and it ended up using
the MapType class which inherits CollectionType and its method looks
like this:
public override ICollection GetElementsCollection(object collection)
{
return ((IDictionary) collection).Values;
}
notice the first one returns the collection which is why the error
about unknow entity class is being raised since it ends up returning a
collection of key value pairs rather than a collection of objects as
what the MapType class does.
So , I how can we somehow get it to use the MapType class since using
a custom type always forces the use of the CollectionType class. If
anyone has an example of doing a custom dictionary collection , that
would be great too.
thanks
scott
