报价验证插件不会阻止在 InvalidPluginExecutionException 上关闭报价

Question

我正在编写一个插件来在保存之前验证报价。我们要强制要求必须有一个报价产品线

可以激活、赢得或丢失报价之前的报价项目。草稿模式没有这个要求

我编写了以下代码，当按下功能区上的 "Close Quote" 按钮并选择 Won 作为原因时，会弹出一个包含错误消息的业务流程错误框。

但是，关闭错误消息并刷新页面后，报价将设置为已关闭。为什么即使抛出异常，报价也会关闭？

仅供参考，插件阶段设置为预操作。

这是我的源代码（更新于 10/02/2017）：

using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ValbrunaPlugins
{
    public class QuoteValidation : IPlugin
    {
        private ITracingService tracingService;

        public void Execute(IServiceProvider serviceProvider)
        {

            // retrieve the context, factory, and service
            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
            IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
            IOrganizationService service = factory.CreateOrganizationService(context.UserId);

            bool isCorrectEvent = context.MessageName == "SetStateDynamicEntity" || context.MessageName == "SetState" || context.MessageName == "Win" || context.MessageName == "Close";
            bool hasEnityMoniker = context.InputParameters.Contains("EntityMoniker");

            // ensure we are handling the correct event and we were passed an entity from the context
            if (!isCorrectEvent || !hasEnityMoniker) return;
            // get the reference to the quote entity
            EntityReference quoteEntityReference = (EntityReference)context.InputParameters["EntityMoniker"];

            Entity quoteEntity = null;
            try
            {
                // get the quote entity from the entity reference
                quoteEntity = ActualEntity.GetActualEntity(quoteEntityReference, service);
            } catch (Exception ex)
            {
                throw new InvalidPluginExecutionException("Quote with id " + quoteEntityReference.Id + " not found.");
            }

            // ensure that we have the correct entity
            if (quoteEntity.LogicalName != "quote") return;

            // write query to retrieve all the details for this quote
            QueryExpression retrieveQuoteDetailsQuery = new QueryExpression
            {
                EntityName = "quotedetail",
                ColumnSet = new ColumnSet(),
                Criteria = new FilterExpression
                {
                    Conditions =
                        {
                            new ConditionExpression
                            {
                            AttributeName = "quoteid",
                            Operator = ConditionOperator.Equal,
                            Values = { (Guid)quoteEntity.Id }
                            }
                        }
                }
            };

            // execute the query to retrieve the details for this quote
            EntityCollection quoteDetails = service.RetrieveMultiple(retrieveQuoteDetailsQuery);

            // retrieve the current status of the quote
            // 0 - Draft
            // 1 - Active
            // 2 - Won
            // 3 - Closed
            int quoteStatus = ((OptionSetValue)(quoteEntity.Attributes["statecode"])).Value;

            // if not in draft mode
            if (quoteStatus != 0)
            {
                // if the amount of details for the quote is less than 1
                if (quoteDetails.Entities.Count < 1)
                {
                    throw new InvalidPluginExecutionException("There must be a quote product line item on a quote before a quote can be activated, won, or lost while not in draft mode.");
                }
            }
        }

    }
}

2017 年 10 月 2 日更新：

我为 SetState 创建了一个单独的步骤并更新了我的源代码。

但是，我仍然遇到同样的问题。当我关闭报价时出现错误，但当我刷新页面时，报价已设置为关闭。

注意：报价处于活动状态，没有报价详情，因此无法赢得报价。

按应有的方式显示业务流程错误。但是，当我刷新页面时，引用的状态已设置为 "Closed"。抛出异常为什么要这么做？

您必须为 SetState 和 SetStateDynamicEntity 消息注册插件步骤。

reference

Why do I need to register on SetState and SetStateDynamicEntity separately?
As I mentioned earlier there are multiple messages that perform the same action in CRM. One such example is SetStateRequest and SetStateDyanmicEntityRequest . If you want to write a plug-in on SetState, then you need to register it on both messages.
