It's an extension method defined in the Cocktail assembly. The method is on the CoroutineFns class.

Hello mgood,
everything is ok but I don't have the ToSequentialResult(); method...where is it defined in the Cocktails.Util assembly?
Thanks again

return op.AsOperationResult<IEnumerable<userMessage>>();

I actually recommend you leave the onSuccess/onFail callbacks and make them optional. In some cases you might find it useful to use the callbacks instead of the returned OperationResult. So, with that said, your method would look like this:
 

public OperationResult<IEnumerable<userMessage>> LoadUserMessages(DateTime data, int ancheMessaggiVisti,

      Action<IEnumerable<userMessage>> onSuccess = null, Action<Exception> onFail = null)

{

     var query = Manager.IF_SP_USER_MESSAGES_SELECTQuery(<parameter>);

     var op = query.ExecuteAsync();

     return op.OnComplete(onSuccess, onFail).AsOperationResult<userMessage>();

}

 
Both, OnComplete and AsOperationResult<T>() will do the cast for you.

I can't remember how it works with Stored Procedures, so Marcel will have to chime in, but when you use the OperationResult you won't have to use onSuccess/onFail as all that functionality is provided by the OperationResult class.]]> Fri, 24 Feb 2012 10:48:25 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3286&PID=12796#12796 CoroutinFns.AsOperation ..how to use? : Hello,if I do so in the applicationrepository... http://www.ideablade.com/forum/forum_posts.asp?TID=3286&PID=12795#12795 Author: pponzano

Hello,
if I do so in the applicationrepository (casting .OperationResult()) can I convert to OperationResult<IEnumerable<T>>() in the viewmodel ? is necessary to pass OnSuccess and onFail in the repository?

Can you not do:

public OperationResult LoadUserMessages(DateTime data, int ancheMessaggiVisti, Action<IEnumerable> onSuccess, Action<Exception> onFail)

    {

        var query = Manager.IF_SP_USER_MESSAGES_SELECTQuery(<parameter>);

 

        var op = query.ExecuteAsync();

 

        return op.OnComplete(onSuccess, onFail).AsOperationResult();

    }

Excuse me ... since I retrieve data from stored procedure how should I implement the methods?
 
Mines are in the form
 

public INotifyCompleted LoadUserMessages(DateTime data, int ancheMessaggiVisti, Action<IEnumerable> onSuccess, Action<Exception> onFail)

    {

        var query = Manager.IF_SP_USER_MESSAGES_SELECTQuery(<parameter>);

 

        var op = query.ExecuteAsync();

 

        return op.OnComplete(onSuccess, onFail);

    }

 

but this won't work as OperationResult, neither OperationResult<IEnumerable<userMessage>>();
 
Thanks

Sorry, minor change. I see your HandleError return IEnumberable<IResult>.
 
        public IEnumerable<IResult> LoadData()
        {
            IsBusy = true;
 
            CanPrintExport = false;
 
 
            OperationResult<IEnumerable<ElencoCollateralsResult>> operation;
            yield return (operation = repository.myMethod(Date)).ContinueOnError();
 
            if (operation.CompletedSuccessfully)
                DataItems = new BindableCollection<myObject>(operation.Result);
 
            if (operation.HasError)
                yield return errorHandler.HandleError(operation.Error).ToSequentialResult();
 
            IsBusy = false;
 
            CanPrintExport = DataItems != null && DataItems.Count() > 0;
        }

You can also write this a little cleaner with Cocktail v0.3.1 (available for download now) if you move the AsOperationResult call into myMethod and have myMethod return OperationResult<IEnumerable<ElencoCollateralsResult>>.
 
        public IEnumerable<IResult> LoadData()
        {
            IsBusy = true;
 
            CanPrintExport = false;
 
 
            OperationResult<IEnumerable<ElencoCollateralsResult>> operation;
            yield return (operation = repository.myMethod(Date)).ContinueOnError();
 
            if (operation.CompletedSuccessfully)
                DataItems = new BindableCollection<myObject>(operation.Result);
 
            if (operation.HasError)
                yield return errorHandler.HandleError(operation.Error);
 
            IsBusy = false;
 
            CanPrintExport = DataItems != null && DataItems.Count() > 0;
        }

OperationResult implements INotifyCompleted and IResult so you can return it as either. ]]> Thu, 23 Feb 2012 09:06:50 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3286&PID=12756#12756 CoroutinFns.AsOperation ..how to use? : Leaving the return type unchanged?... http://www.ideablade.com/forum/forum_posts.asp?TID=3286&PID=12755#12755 Author: pponzano

You can change that to:

  yield return 

                               repository.myMethod(Date, results =>

                               {

                                   DataItems = new BindableCollection<myObject>(results.Cast<ElencoCollateralsResult>());

                               },

                               e =>

                               {

                                   Caliburn.Micro.Coroutine.BeginExecute(errorHandler.HandleError(e), null, null);

                               }).AsOperationResult();

Hello,
I'm migrating to Cocktail... I got a problem with the AsOperationResult ..

    

public IEnumerable<IResult> LoadData()

   {

       IsBusy = true;

       CanPrintExport = false;

 

 

       CoroutineFns.AsOperationResult(

       yield return CoroutineFns.AsOperationResult(() =>

                               repository.myMethod(Date, results =>

                               {

                                   DataItems = new BindableCollection<myObject>(results.Cast<ElencoCollateralsResult>());

                               },

                               e =>

                               {

                                   Caliburn.Micro.Coroutine.BeginExecute(errorHandler.HandleError(e), null, null);

                               }));

 

       IsBusy = false;

       CanPrintExport = DataItems != null && DataItems.Count() > 0;

 

   }


I got the error

Error    9    Cannot convert lambda expression to type 'IdeaBlade.EntityModel.INotifyCompleted' because it is not a delegate type  

How can I fix it?

Thanks
