dynamics-crm-2011 - CRM 2011 Post Operation Plugin - 尝试保存引用实体时不存在主要实体

Question

我正在尝试为现场 Dynamics CRM 2011 安装创建插件。

我已经注册了插件如下:

留言:创建

主要实体:联系方式

执行阶段:术后

执行方式:同步

执行顺序:1

插件代码如下:

public void Execute(IServiceProvider serviceProvider)
{
    var pluginExecContext = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

    var orgServiceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
    var orgService = orgServiceFactory.CreateOrganizationService(pluginExecContext.UserId);
    var orgServiceContext = new OrganizationServiceContext(orgService);

    var tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));

    if (pluginExecContext.InputParameters.Contains("Target") &&
            pluginExecContext.InputParameters["Target"] is Entity)
    {
        var target = (Entity)pluginExecContext.InputParameters["Target"];

        if (target.LogicalName != Contact.EntityLogicalName) 
            return;

        try
        {
            var customerServicesUser = orgServiceContext.CreateQuery(SystemUser.EntityLogicalName)
                .Where(x => (string)x["fullname"] == "Customer Services").FirstOrDefault();

            if (customerServicesUser == null)
                throw new InvalidPluginExecutionException("No Customer Services user exists.");

            var sendEmail = new cdi_sendemail
                {
                    cdi_fromrecordowner = false,
                    cdi_contactid = new EntityReference(Contact.EntityLogicalName, pluginExecContext.PrimaryEntityId),
                    cdi_fromid = new EntityReference(SystemUser.EntityLogicalName, customerServicesUser.Id)
                };

            tracingService.Trace("PostContactCreate plug-in: Creating the cdi_sendemail entity.");
            orgService.Create(sendEmail);
        }
        catch (FaultException<OrganizationServiceFault> ex)
        {
            throw new InvalidPluginExecutionException("An error occurred in the PostContactCreate plug-in.", ex);
        }
        catch (Exception ex)
        {
            tracingService.Trace("PostContactCreate plug-in: {0}", ex.ToString());
            throw;
        }
    }
}

当我使用 pluginregistration 工具分析插件并调试错误异常时，我收到以下错误:

Contact With Id = abbc7e0a-20a0-e111-a36e-005056860004 Does Not Exist.

我有点理解插件正在尚未提交的 SQL 事务中执行。 CRM SDK 示例中的“FollowupPlugin”也创建了一个引用实体，声明它需要异步注册，这也是有意义的，因为它允许提交 SQL 事务。

所以我想我的问题是，如何在同步插件中创建引用实体？

看着SDK example for a very similar example - 我认为您需要在沙箱中注册。

Register this plug-in for an account entity, on the Create message, and in asynchronous mode. Alternately, you can register the plug-in on a post-event in the sandbox.
