I can't get my Siverlight app to update the source. RIA services never get called. I suspect Silverlight is failing a validation but I don't see what that would be. The problem is that no errors display. In debug the code below is called.

op.HasError=True but submitOp.EntitiesInError.Count=0 so no messages ever are displayed.
op has many properies that should tell me what went wrong but I can't one with any clue as to why an error occured.
The Entity has my changed values and looks correct. I don't know how to troubleshoot this since I can't step any further into code. As most problems go, I have spent days on this.
Thanks

mmBusinessConrollerProxy.cs:
		public virtual void HandleOperationError(OperationBase op)
		{
			if (op.HasError)
			{
				this.ErrorMessage = "";

				op.MarkErrorAsHandled();

				SubmitOperation submitOp = op as SubmitOperation;

				if (submitOp != null)
				{
					foreach (Entity entity in submitOp.EntitiesInError)
					{
						foreach (ValidationResult error in entity.ValidationErrors)
						{
							this.ErrorMessage += error.ErrorMessage + "\r\n";
						}
