I am a new DevForce user and having problems getting the BigShelf sample application to work. I am able to pull up the default.aspx page and sucessfully login but I get no data back from the entity manager. I checked the acompaning writeup and it says to look for a http response code of 500 for starters. Well, I am getting this 500 error, but it is not because the RAI Services 1.0 SP2 update has not been installed. Instead, I am getting a message stating that 'BigShelf.Models.Book.EntityAspect' is already
defined. below is both the reponse error code and the response body. Thanks- Don Key Value |

Hi donn, It looks like we broke this sample in our last release of DevForce. The problem is in the RiaEntity class in the Models folder. The class definition should look like this: public abstract partial class RiaEntity : IEntity { [Exclude] public new EntityAspect EntityAspect { get { return base.EntityAspect; } } } |

now getting a different error: {"ErrorCode":500,"ErrorMessage":"Method not found: 'Void System.ServiceModel.DomainServices.Server.DomainServiceContext..ctor(System.IServiceProvider, System.ServiceModel.DomainServices.Server.DomainOperationType, System.String)'.","IsDomainException":false,"StackTrace":" at System.ServiceModel.DomainServices.Hosting.DomainOperationInvoker.GetDomainService(Object instance, String operationTag)\u000d\u000a at System.ServiceModel.DomainServices.Hosting.DomainOperationInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs)"} I tried rebuilding and the compiler now complains as well. Says the base class for RiaEntity: IEntity does not have a definition for "EntityAspect" Error 1 'object' does not contain a definition for 'EntityAspect' File: RiaEntity.cs Line: 20 Column: 31 this is what I found in the IEntity definition:
public interface IEntity { // Summary: // Returns the IdeaBlade.EntityModel.IEntity.EntityAspect for the entity. EntityAspect EntityAspect { get; } } |

OK, the change I posted should work. There was already a file named RiaEntity.cs in the project, so I wanted you to replace just the class definition. The entire RiaEntity.cs file contents should look like this: using System; The only change from the original download should be the addition of the IEntity implementation. If you're still seeing a problem, I also fixed the sample available from the DRC, so you can re-download that if necessary. |

Yes, I did only replace the RaiEntity.cs class definition, not create a new file. anyway I pulled down the new version of BigShelf from the DRC and do see the changes to the file as mentioned above. (so I believe I have the version you want me to have). I am still getting the same error though again referencing the Interface => Ideablade.EntityModel.IEntity The compiler says: "Unknown member 'EntityAspect' of 'BigShelf.Models.RiaEntity'"  I have also installed this on 2 separate workstations both getting the same error. I also have the latest version of WCF RIA Service 1.0 SP2 installed (release date: 9/1/2011)

Hmm. The RiaEntity partial class here is "extending" the RiaEntity defined in BigShelf.IB.Designer.cs. Please check if you see RiaEntity defined in that file as well. I see that I'm still using a preview version of WCF RIA Services SP2, so I'll upgrade now to see if that's causing the problem.

I am fearing some incompatibility introduced between April and September versions of both SP2 and RiaServices.Toolkit. It DEFINITELY works with latest DevForce and APRIL SP2/TOOLKIT. Investigating this weekend. Wish us luck. :)

Thank You Ward. You and I met at PDC Underground in LA one or two years back. Sorry to make you work over the weekend.

Sorry but we haven't returned to this. The RIA/JS project has undergone some dramatic transformations/improvements. I can't describe them but let's just say that a lot has changed. We're holding off until they go public. Consider the RIA/JS Big Shelf sample we described as a concept-only "proof of concept". Nice to know that a solution is forthcoming. We can tell that THIS approach will involve a RIA Services wrapper around a DevForce model. This has worked and it will work again. But no one should be doing anything serious with the current bits. Keep pinging. We won't let this drop. It's just not smart to invest in this right now with so much that is about to change.

Hi Mr WardBell, I think that the RIA/JS project has become an obligatory requirement due to the switch from Silverlight to HTML5 strategies that is adopted by all platforms, i want to know if there is a progess in this project ? please things has become more serious, and may be the word 'Silverlight' will become an old fashioned expression in the near future.
