The relationship between the two objects cannot be defined because they are attached to different ObjectContext objects duplicate objects

Hi I am using Entity Framework Code First, for my Database and CRUD operations, but when I am trying to add into couple of tables using entities.
Here is the message I am getting:
The relationship between the two objects cannot be defined because
they are attached to different ObjectContext objects duplicate objects
My create function is as below:
public T Create(T item)
{
try
{
if (ufb != null && ufb.CurrentUser != null)
{
SetValue("CreatedByUserId", item, ufb.CurrentUser.Id);
SetValue("UpdatedByUserId", item, ufb.CurrentUser.Id);
}
SetValue("DateCreated", item, DateTime.Now);
SetValue("DateUpdated", item, DateTime.Now);
var newEntry = this.DbSet.Add(item);
this.Context.Database.Log = message => LogHandler.LogInfo(1111, message);
try
{
this.Context.SaveChanges();
}
catch (Exception ex)
{
LogHandler.LogInfo(2501, ex.Message);
}
BuildMetaData(item, true, true);
return newEntry;
}
catch (DbEntityValidationException dbEx)
{
// http://forums.asp.net/t/2014382.aspx?Validation+failed+for+one+or+more+entities+See+EntityValidationErrors+property+for+more+details+
string msg = string.Empty;
foreach (var validationErrors in dbEx.EntityValidationErrors)
{
foreach (var validationError in validationErrors.ValidationErrors)
{
msg += validationError.PropertyName;
msg += "---";
msg += validationError.ErrorMessage;
msg += "||";
}
}
throw new Exception("7777 CREATE EntityValidationErrors: " + msg);
}
}
Here is how I am trying to call the create method for couple of Entities, can somebody please suggest me what am I doing wrong, any help please
public InspectionItem Create(InspectionItem inspectionItem)
{
try
{
//------------------------------------------------------
// save the indexes to the multiple categories,
// then clear the list of category objects in the
//------------------------------------------------------
List<int> inspectionCategoryIdlist = new List<int>();
foreach (var itemCat in inspectionItem.InspectionItemCategory)
{
int itemCatId = itemCat.ViolationTypeId;
inspectionCategoryIdlist.Add(itemCatId);
}
inspectionItem.InspectionItemCategory.Clear();
inspectionItem.InspectionItemNumber = "TEMP"; // just get past the Create
var saveInspectionItemCategories = inspectionItem.InspectionItemCategory;
inspectionItem.InspectionItemNumber = CalculateInspectionItemNumber(inspectionItem.InspectionItemId);
UnitOfWork.InspectionItemRepository.Create(inspectionItem);
if ((inspectionItem != null) && (inspectionItem.InspectionItemId != null) && (inspectionItem.InspectionItemId > 0))
foreach (var violationTypeId in inspectionCategoryIdlist)
{
var a = new InspectionItemViolationCategory();
a.InspectionItem = inspectionItem;
var violationType = new ViolationType();
violationType = UnitOfWork.ViolationTypeRepository.Find(violationTypeId);
a.ViolationType = violationType;
UnitOfWork.InspectionItemViolationCategoryRepository.Create(a);
}
return inspectionItem;
}
catch (Exception ex)
{
LogHandler.LogError(2101, "Commit Fail in Inspection Item Create", ex);
throw ex;
}
}
Any suggestion or code sample anything helps, thanks a lot.

CRM workflow: How to get all the records from a subgrid as a list of entities and perform multi-retrieve

As the title suggests, I do not know how to convert entity.attributes ["subgrid"] as a list of entities, on which to run the multiretrieve:
My code for now:
protected override void Execute(CodeActivityContext executionContext)
{
ITracingService tracingService = executionContext.GetExtension<ITracingService>();
IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
var entity = (Entity)context.InputParameters["Target"];
if (entity.LogicalName != "account")
{
return;
}
var currentAccountId = entity.Id;
try
{
if (!entity.Contains("Subgrid"))
{
return;
}
var itemsOnSubgrid = entity.Attributes["Subgrid"];
if(itemsOnSubgrid == null)
{
return;
}
else
{
//if subgrid exist and is not null
//List of entities needed
}
}
catch (Exception ex)
{
tracingService.Trace("MyWorkflow: {0}", ex.ToString());
throw new InvalidPluginExecutionException(ex.Message);
}
}

As you are writing code in a custom workflow assembly - the entity at this point does not know anything about the form it is being called from, and does not have a "Subgrid" property to allow you to access the related records.
You will need to do a sperate query to retrieve related contacts (as an example) using the target entity's "accountid" property to relate to the contacts' "parentcustomerid" property.

Assume you are looking for a method to get all associated records for a particular record.
If that is the case, I would have written something like this. Hope that helps.
private EntityCollection GetAssociatedRecords(string relationshipName, string relatedEntityName, string entityName, Guid entityId,OrganizationService service)
{
EntityCollection result = null;
try
{
QueryExpression query = new QueryExpression();
query.EntityName = relatedEntityName;
query.ColumnSet = new ColumnSet(false);
Relationship relationship = new Relationship();
relationship.SchemaName = relationshipName;
relationship.PrimaryEntityRole = EntityRole.Referencing;
RelationshipQueryCollection relatedEntity = new RelationshipQueryCollection();
relatedEntity.Add(relationship, query);
RetrieveRequest request = new RetrieveRequest();
request.RelatedEntitiesQuery = relatedEntity;
request.ColumnSet = new ColumnSet(true);
request.Target = new EntityReference
{
Id = entityId,
LogicalName = entityName
};
RetrieveResponse response = (RetrieveResponse)service.Execute(request);
RelatedEntityCollection relatedEntityCollection = response.Entity.RelatedEntities;
if (relatedEntityCollection.Count > 0)
{
if (relatedEntityCollection.Values.Count > 0)
{
result = (EntityCollection)relatedEntityCollection.Values.ElementAt(0);
}
}
}
catch (Exception exception)
{
throw exception;
}
return result;
}
In that based on the role of the other entity change the Primary Entity Role between Referencing and Referenced.
Hope that helps. Let me know if my assumption is wrong.

Get the list of notes

How to obtain the list (or e.g. collection) of guids of all notes associated with current entity?
I know that it is in some way connected with service.Retreive(...), but can't make working code.
Attach 1:
public void Execute(IServiceProvider serviceProvider)
{
Entity entity = null;
var context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
if (entity.Contains("new_parentopportunity"))
{
try
{
IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = factory.CreateOrganizationService(context.UserId);
Guid projectGuid = entity.Id;
Guid oppGuid = ((EntityReference)entity["new_parentopportunity"]).Id;
for (int i = 0; i < 100; i++) //Instead of 100, I'll place obtained collection.Length
{
Entity opp = service.Retrieve("", oppGuid, new Microsoft.Xrm.Sdk.Query.ColumnSet(true)); //RETREIVE ENTITY NOTE HERE
var temop = CreateNoteAttachment(opp);
service.Create(temp);
}
}
catch (Exception ex)
{
throw new InvalidPluginExecutionException("An error occurred in the plug-in.", ex);
}
}
}
private Entity CreateNoteAttachment(Entity oppNote)
{
//some code here
}
Update 1:
I also write it in queries, can you look at this, whethere everything fine there?
PasteBin

Two ways to query for related notes:
Early Bound:
var notes =
service.AnnotationSet.Where(annotation => annotation.Opportunity_Annotation.Id == entity.Id)
.Select(annotation => annotation.Id)
.ToList();
FetchXml:
var fetchXml = string.Format("<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>" +
"<entity name='annotation'>" +
"<attribute name='annotationid' />" +
"<filter type='and'>"+
"<condition attribute='objectid' operator='eq' value='{0}'/>"+
"</filter>"+
"</entity>" +
"</fetch>", entity.Id);
var response = service.RetrieveMultiple(new FetchExpression(fetchXml));
var notes = response.Entities;

Create/Update method not allowed in "Activity Pointer" CRM 2011

Am having a plugin that moves the activities of lead to opportunity on qualify. I have registered the plugin on "Create" of opportunity and the following is the code
public void Execute(IServiceProvider serviceProvider)
{
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
Entity entity;
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
entity = (Entity)context.InputParameters["Target"];
if (entity.Attributes.Contains("originatingleadid") == false) return;
}
else
{
return;
}
try
{
//.....
EntityReference Lead = (EntityReference)entity.Attributes["originatingleadid"];
Guid LeadGuid = Lead.Id;
MoveActivitiesFromLeadToOpportunity(service, LeadGuid, Opportunityid);
}
catch (FaultException<OrganizationServiceFault> ex)
{
throw new InvalidPluginExecutionException(
"An error occurred in the plug-in.", ex);
}
}
private void MoveActivitiesFromLeadToOpportunity(IOrganizationService service, Guid LeadID, Guid OpportunityID)
{
ConditionExpression condition = new ConditionExpression();
condition.AttributeName = "regardingobjectid";
condition.Operator = ConditionOperator.Equal;
condition.Values.Add(LeadID.ToString());
var query = new QueryExpression("activitypointer");
query.Criteria.AddCondition(condition);
//query.Conditions.Add("reagrdingobjectid", ConditionOperator.Equal, theIdOfTheRelatedRecord);
query.ColumnSet = new ColumnSet(true);
var activities = service.RetrieveMultiple(query).Entities;
foreach (var activity in activities)
{
var castedActivity = (ActivityPointer)activity;
if (castedActivity.ActivityTypeCode == "email")
{
castedActivity.Id = Guid.NewGuid();
castedActivity["regardingobjectid"] = new EntityReference("opportunity", OpportunityID);
//service.Create(castedActivity);--->Exception thrown
//service.Update(castedActivity);---->Tried this one too.Exception is thrown stating method not supported on "ActivityPointer"
}
}
Can somebody shed light on this? Am i missing something here? Thank you

You need to query for the exact entity type, because you can't update an activitypointer
private void MoveEmailsFromLeadToOpportunity(IOrganizationService service, Guid LeadID, Guid OpportunityID)
{
ConditionExpression condition = new ConditionExpression();
condition.AttributeName = "regardingobjectid";
condition.Operator = ConditionOperator.Equal;
condition.Values.Add(LeadID.ToString());
var query = new QueryExpression("email");
query.Criteria.AddCondition(condition);
query.ColumnSet = new ColumnSet(true);
var emails = service.RetrieveMultiple(query).Entities;
foreach (var email in emails)
{
email["regardingobjectid"] = new EntityReference("opportunity", OpportunityID);
service.Update(email);
}
}
you can also write a method that will retrieve first all the activities (as you already did) check the ActivityTypeCode after retrieve and update each single record depending on activity type (email, fax, ...)

Try commenting out this line:
castedActivity.Id = Guid.NewGuid();
And then just do your Update:
service.Update(castedActivity)
You are just updating the RegardingObjectId, not creating a new activity, so you shouldn't change the Id and you shouldn't use Create.

EventStore duplicate commit exception

UPDATE:
We are getting getting System.Data.SqlClient.SqlException. The message is:
Violation of PRIMARY KEY constraint 'PK_Commits'. Cannot insert duplicate key in object 'dbo.Commits'.\r\nThe statement has been terminated
It seems like EventStore is using streamid and commitid as unique id.
We use event store to append events as below.
public bool TryAppend(object[] content)
{
if (content == null)
throw new ArgumentNullException("content");
try
{
using (var stream = m_storage.OpenStream(m_streamID, 0, int.MaxValue))
{
var versionInStore = stream.StreamRevision;
content.ToList().ForEach(m =>
{
var version = ++versionInStore;
var key = string.Format("{0}-{1:00000000}", m.GetType().Name, version);
var savedMessage = new SavedRecord(key, version, m);
stream.Add(new EventMessage { Body = savedMessage });
});
stream.CommitChanges(Guid.NewGuid());
}
return true;
}
catch (Exception e)
{
m_logger.LogError(e);
return false;
}
}
The configuration of EventStore is as below. We are using Sql Serer 2008 as persistance store.
return Wireup.Init()
.LogToOutputWindow()
.UsingSqlPersistence(m_connectionName)
.WithDialect(new MsSqlDialect())
.EnlistInAmbientTransaction() // two-phase commit
.InitializeStorageEngine()
.UsingJsonSerialization()
.Compress()
.UsingSynchronousDispatchScheduler()
.DispatchTo(new DelegateMessageDispatcher(DispatchCommit))
.Build();
Any ideas why are gettin the dupplicate commit exception?
Thanks

Have got the same issue; in my case it was probably because of different threads was adding different events to the stream with same id at the same time.
Have writtent the following code to be able to retry adding events:
private void TryAddEvent(IStoreEvents storeEvents, IUserEvent anEvent, Guid streamId)
{
var isCommitSuccessful = false;
for (var i = 0; i < 10 && !isCommitSuccessful; i++)
{
try
{
using (var stream = storeEvents.OpenStream(streamId, 0, int.MaxValue))
{
stream.Add(new EventMessage {Body = anEvent});
if (stream.UncommittedEvents.All(e => e.Body != anEvent))
{
stream.Add(new EventMessage {Body = anEvent});
}
stream.CommitChanges(Guid.NewGuid());
}
isCommitSuccessful = true;
}
catch (Exception ex)
{
if (!(ex is SqlException) && !(ex is ConcurrencyException))
{
throw;
}
using (var stream = storeEvents.OpenStream(streamId, 0, int.MaxValue))
{
if (stream.CommittedEvents.Any(e => e.Body == anEvent))
{
isCommitSuccessful = true;
}
}
}
}
if (!isCommitSuccessful)
{
throw new ConcurrencyException(String.Format("Cannot add {0} to event store", anEvent.GetType()));
}
}
Hope it would help.
