Plugin for copying notes and attachements from lead to contact whis is converted from lead for Microsoft Dynamics CRM 4.0

I've been asked to write plugin for following scenario:
When user converts lead to contact - all attachements and notes must be copied to retrieved contact.


Code of the plugin:

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Crm.Sdk;
using Microsoft.Crm.SdkTypeProxy;
using Microsoft.Crm.Sdk.Query;

namespace LeadConversionPlugin
{
public class ContactCreationHandler : IPlugin
{
#region IPlugin Members

public void Execute(IPluginExecutionContext context)
{
if (context.MessageName == MessageName.Create &&
context.InputParameters.Contains("Target") &&
context.InputParameters["Target"] is DynamicEntity)
{
DynamicEntity entity = (DynamicEntity)context.InputParameters["Target"];

//Check that target entity is contact
if (entity.Name != EntityName.contact.ToString())
return;

//Check that this contact is created in the way of
//convertion from lead
if (!entity.Properties.Contains("originatingleadid"))
return;

//Source Lead Identifier
Guid leadid = ((Lookup)entity["originatingleadid"]).Value;

//Target Contact Identifier
Guid contactid = (Guid)context.OutputParameters["Id"];

ICrmService crmservice = context.CreateCrmService(true);

//Just build the query which will be used to retrieve
//all child annotations (notes and attachements)
QueryByAttribute query = new QueryByAttribute();
query.ColumnSet = new AllColumns();
query.EntityName = EntityName.annotation.ToString();

query.Attributes = new string[] { "objectid" };
query.Values = new object[] { leadid };

RetrieveMultipleRequest request = new RetrieveMultipleRequest();
request.Query = query;
request.ReturnDynamicEntities = false;

RetrieveMultipleResponse response = (RetrieveMultipleResponse)crmservice.Execute(request);

foreach (annotation note in response.BusinessEntityCollection.BusinessEntities)
{
//Just remove Key field of annotation
note.annotationid = null;

//Replace referencing object lookup with newly created contact lookup
note.objectid = new Lookup(EntityName.contact.ToString(), contactid);
note.objecttypecode = new EntityNameReference(EntityName.contact.ToString());

//And Create the annotation record
crmservice.Create(note);
}
}
}

#endregion IPlugin Members
}
}


Step for this plugin must be registered as a Post Create Syncronous Parent Pipeline.

  2. Hi I am also trying to use the same code for CRM 2011. Just difference is that I have used linq rather than query. I am able to retrieve the notes but when I am trying to generate the note for account entity, I am getting the below error :-


    EntityState must be set to null, Created (for Create message) or Changed (for Update message)

    Any idea how can I resolve this?

    1. 1. I don't see your code.
      2. Use debugger and google.
