我们正在尝试将CRM 2011从RU 11更新为RU 14，以便在RU 14准备就绪时能够安装RU 15。一直在解决有关此次更新的各种问题，因为微软在Cross平台上做了相当多的更改，显然自从11岁转为14次。
现在，我的主要问题是我有一个在创建服务约会时同步运行的插件。它负责执行多项操作，例如比较值或使用其他实体的值来填充服务活动记录中的数据。关于奇怪的错误是什么，因为在Post Operations上进行了更改，所以必须完成_service.Update（实体）才能在表单和数据库中看到更改。如果我逐步调试代码，除非代码到达.Update，否则一切都会顺利通过。当调用更新时，CRM会抛出一个意外错误。当我进入TraceLogs时，我发现了这一点：

我已经做了不同的更改，试图找出问题所在，其中包括关闭所有已注册的插件，而不是微软的插件和此插件。关闭表单中的所有JavaScript，以防任何值被更改，使其抛出错误，硬编码状态代码和状态代码，因为在线发现的一些相关问题，评论插件中的所有代码，只留下_service。如果传递了无效值，则更新（实体）但更新仍会抛出错误，而我在网上找到的其他东西似乎是一个解决方案。我一直在犯这个错误已经有一段时间了，并希望有更多的想法与我一起思考这个问题。由于与插件绑定的逻辑，插件必须在后续操作中同步运行。
任何帮助都表示赞赏，如果您需要更多信息以了解可能发生的情况，请告诉我们。

我一直在用同样的问题撕掉我的头发。我的相同代码在其他类型的实体上工作正常，因此我将其隔离仅发生在活动（即使用ActivityBase的任何内容）上。这看起来像是CRM内部对象模型中的一个错误（至少存在于UR11，这是我正在运行的版本），在以下情况下会发生：
所有活动实体与存在活动参与者（活动参与者）的其他实体进行比较的功能之一，这些参数是“参加者”，“客户”，有用的电子邮件字段（“收件人”，“CC”等标准字段'，'BCC'），可以包含许多不同的类型，例如'RequiredAttendee'，'Organizer'，'To'，但重要的是它也创建一个用于记录'所有者'（有关完整列表，请参阅http://msdn.microsoft.com/en-us/library/gg328549.aspx。
在查看正在执行的SQL之后（以及在Microsoft.Crm.ObjectModel中的.NET反编译器中偷偷摸摸地查看），看来问题在于活动方是（或不是）的顺序正在创建或更新。对于 之后的活动，通常的Create（）消息处理（包括您的插件代码）已完成执行，这些ActivityParty记录（包括所有者的一个）将从实体数据中填充。在Update（）上还有一个检查来处理ActivityParties所需的任何更改，但是这（错误地）假定已经创建了ActivityParty记录。
..所以如果你在Create消息中调用Update，那么在Update ActivityParty抛出它的ArgumentOutOfRangeException之前，初始的Create消息还没有完成，因为它还没有任何记录。
这也解释了为什么它在异步模式下按预期工作，因为ActivityParties是在通常的Create（）过程之后但在插件执行代码触发的Update运行几秒之后成功创建的。
根据您尝试实现的目标，可以通过改变您的插件来改变预操作事件。
