    I am trying to update a record using ServiceContext as follows:

    First I find the record I’m looking for depending on an attribute:

    var someRecord = serviceContext.CreateQuery(“someEntity”)

                       .FirstOrDefault(s => s.GetAttributeValue<string>("new_name") == someNameVar);

     

     

    I want to update the attribute

    someRecord["new_name"] = “updated value for name";

     

    if (!serviceContext.IsAttached(someRecord))

         serviceContext.Attach(someRecord);

     

    serviceContext.UpdateObject(someRecord);

    serviceContext.SaveChanges();

     

     

    Everything works until I hit the SaveChanges() call. At this point I get an exception that there was an error on the server. When I check the server log here is one of the exceptions that I get (that gives the most info):

    [2011-10-25 18:07:38.878] Process: w3wp |Organization:00000000-0000-0000-0000-000000000000 |Thread:   23 |Category: Platform |User: 00000000-0000-0000-0000-000000000000 |Level: Error | ExceptionConverter.ConvertMessageAndErrorCode

    Have not been able to make headway on this - any ideas on what could be causing this would be appreciated.

    Hi Mate

    check if somerecord has any value and of what type?

    var someRecord = serviceContext.CreateQuery(“someEntity”)

                       .FirstOrDefault(s => s.GetAttributeValue<string>("new_name") == someNameVar);

    may be you need to change the following line

    .FirstOrDefault(s => s.GetAttributeValue<string>("new_name") == someNameVar).ToEntity();

    I hope this helps.

    Make sure you do not have to manually attach the object to the context. Since you have just read the record, context should already be tracking it. 

    I guess since you are attaching it to conext manually, it may be throwing that error.

    Thanks Amreek -

    There is no .ToEntity() method - there's a .ToEntity<entityType>() method - but since I'm working with late binding I don't have access to a fixed class for my entity. That being said, the someRecord variable does get returned as an Entity object and I have access to all of the properties of it - including Id and all attributes.

    Thanks Sam - yeah, that's not the case. Walking through the code the line:

         serviceContext.Attach(someRecord);

    doesn't actually get called so this isn't the issue.

    Really stumped with this one...

    Hi James -

    No I did not - I did the coding without using any LINQ constructs.

    That's unfortunate. It seems the problem is specifically in plug-ins - we did a test using identical LINQ and context.Update() code in a plug-in and in an external web-site, and the same identical code ran in the website but threw that Exception in the plug-in. We haven't tried creating a new context from scratch in a plug-in and using that yet - we've run out of time so I'm just going to use the API in the standard way too.

    Hi,

    I have found that this is a bug in crm and is fixed with Update Rollup 7.

    Here are the release notes:

    Assume that you use LINQ in a Microsoft Dynamics CRM plugin with the OrganizationServiceContext object to retrieve related records. When you update the records, you receive the following error message: Type: System.InvalidOperationException Message: The entity is read-only and the 'Id' property cannot be modified. Use the context to update the entity instead

    All the best,
