Thanks, that's worked nicely :)
/Pete From: [email protected] [mailto:[email protected]] On Behalf Of Gunnar Liljas Sent: 05 November 2013 17:30 To: [email protected] Subject: Re: [nhusers] POCO associated with dynamic-map entity If you turn ADictionary into a plain IDictionary (the non-generic type) you can use dynamic-component. http://ayende.com/blog/3942/nhibernate-mapping-dynamic-component 2013/11/5 Pete Appleton <[email protected]> Is it possible to have just one entity in a session operating as a dynamic-map, all other entities being mapped as POCO's? For example: <class name="SomeNamespace.SomePOCO, SomeAssembly" > <id>...</id> <property>...</property> <many-to-one name="ADictionary" entity-name="ADictionary" ></many-to-one> </class> <class entity-name="ADictionary> <id>...</id> <property>...</property> </class> public class SomePOCO { public virtual int Id { get; protected set; } public virtual IDictionary<string,object> ADictionary { get; protected set; } // etc } This is just R&D work at the moment, looking at different ways of storing key-value data pairs associated with an entity. We've been using a normalised EAV-style approach so far but want to compare it with the denormalised "ultra wide table" approach for which a dynamic-map seems ideally suited. A couple of attempts at this have produced some interesting exceptions such as "System.InvalidCastException: Unable to cast object of type 'NHibernate.Proxy.Map.MapProxy' to type 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'" ; am I doing something wrong, or is this simply not a viable idea?
