Hi,

I have changed a varchar column to a smallint identity column, regenerated using the Business Layer Generator, but when I run my application I get this error:

Column 'AgentNumber' is read only.

in my AgentEntity class on this code:

		public Int16 AgentNumber
		{
			get
			{
				if (this.Row != null)
					return (Int16)mmType.GetNonNullableDbValue(this.Row["AgentNumber"], "System.Int16");
				else
					return this._agentNumber;
			}
			set
			{
				if (this.Row != null)
					this.Row["AgentNumber"] = value; 
				this._agentNumber = value;
				this.OnPropertyChanged(new PropertyChangedEventArgs("AgentNumber"));
			}
		}
		private Int16 _agentNumber;

The error occurs on this.Row["AgentNumber"] = value;

What have I done wrong/missed out here?
