Hello, I need help in this ..
I am using NHibernate for my entities ... Also I have nested entities as foreign keys to my database ,,
Also I am using the CRUD GridPanel that read its data from an httpHandler just like the example in here:

for example :
public class Column 
public virtual string CharMin {get;set;}
public virtual string CharMax {get;set;}
public virtual ColumnDataType ColumnDataType{get;set;}
public virtual string CreatedDate{get;set;}
public virtual Column ForeignKey {get;set;}
public virtual int ?Id {get;set;}
public virtual string IsNull{get;set;}
I want to serliaze this entity and I want my json to contain my sub entites .
