rereading for the 50th time the help I just noticed I need to remove the "Get" prefix when I call my query

var qry = new EntityQuery<Patient>("GetPatientsFromIPP");

changed to

var qry = new EntityQuery<Patient>("PatientsFromIPP");

works !

Hi,

I have a view model using 2 differents models. I am using on single EntityManager (not one of the autogenerated by devforce with the model) to manage them.

To be able to call specific Query on the server I created a Named Query but when I try to call it from the client I get the following error :


Caught exception: System.Exception: Unable to locate public query method on server for: 'GetPatientsFromIPP' à IdeaBlade.EntityModel.Edm.UdtTransformVisitor.GetUdtQueryable(String entitySetName, Type returnEntityType, List`1 parameters) à IdeaBlade.EntityModel.Edm.UdtTransformVisitor.VisitConstant(ConstantExpression ce) à IdeaBlade.Linq.ExpressionVisitor.VisitExpressionCore(Expression e) à IdeaBlade.Linq.TransformExpressionVisitor.VisitExpressionCore(Expression expr) à IdeaBlade.Linq.ExpressionVisitor.VisitExpression(Expression expr) à IdeaBlade.Linq.ExpressionVisitor.Visit(Expression expr) à IdeaBlade.EntityModel.Edm.UdtTransformVisitor.Transform(EntityQuery query) à IdeaBlade.EntityModel.Server.EntityServer.Fetch(SessionBundle sessionBundle, IEntityQuerySurrogate surrogate) à SyncInvokeFetch(Object , Object[] , Object[] ) à System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs) à System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc) à System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc) à System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage41(MessageRpc& rpc) à System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage4(MessageRpc& rpc) à System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage31(MessageRpc& rpc) à System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage3(MessageRpc& rpc) à System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage2(MessageRpc& rpc) à System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage11(MessageRpc& rpc) à System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage1(MessageRpc& rpc) à System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)


I did exactly what it is said in the documentation (well I think).


My model assembly is correctly probed by the server :

Probe Assemblies: Test.Common.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null :: Test.Patients.Server.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null


In the model assembly (on the server) I added a class with my query definition

    [EnableClientAccess]    public class PatientNamedQueryProvider    {
        public IQueryable<Patient> GetPatientsFromIPP(string ipp)        {            return new EntityQuery<Patient>().Include("Personne").Where(p => p.IPP == ipp);
        }
    }
In my Dataservices on the client here is my Code (I have a reference to the client model which doesn't know the PatientNamedQueryProvider Class)   :

        public void GetPatientsFromIPP(string ipp, Action<IEnumerable<Patient>> onSuccess, Action<Exception> onFail)        {            var qry = new EntityQuery<Patient>("GetPatientsFromIPP");            qry.Parameters.Add(new EntityQueryParameter(ipp));             Manager.ExecuteQueryAsync(qry, (op) =>                                               {                                                   if (op.CompletedSuccessfully)                                                   {                                                       if (null != onSuccess)                                                       {                                                           onSuccess(op.Results);                                                       }                                                       else                                                       {                                                           if (null != onFail)                                                           {                                                               op.MarkErrorAsHandled();                                                               onFail(op.Error);                                                           }                                                       }                                                   }                                               });        }


I first though I had an issue because of the parameters so I tried without and I get the same error.

What I am missing ?
