【问题描述】：
更新 我从这个论坛以及 Dynamics 论坛中提取了一些信息，并且我的代码可以正常工作。我的代码中的主要问题是我只查看了 preImage，但在大多数情况下，三个值之一将被更新，这意味着我无法定位该特定字段的 preImage。我将逻辑更改为使用 Collection 属性（更新的值）如果它已更新，但如果它没有更新则使用 PreImage 值 - 这使得代码工作，并且每次都会触发更新 - 不再需要触发插件两次！这是更新后的代码 - 它比原始代码更高效、更简洁（向下滚动以查看旧/非工作代码）。我还添加了一些 cmets 使其更容易理解。感谢所有人的帮助（无论是在 SO 上，还是在 Dynamics 论坛上！）

原帖 再来一次！昨天，我意识到我不使用 PreImage 来获取未包含在更新的属性集合中的值的方法中的错误 - SCORE！现在，插件工作，但它只在我触发插件时才工作。
所以，似乎插件实际上正在触发（我可以在设置 > 插件配置文件中看到插件配置文件），但没有执行我需要的更新，直到我第二次触发插件。这似乎发生在我正在监听的所有 3 个属性上，并且每个属性都需要更新两次（例如，如果我更新属性 1，插件不会更新我的值，如果我再更新属性 2，插件仍然不会更新我的值，直到我再次重新更新属性 1 或属性 2）。当我分析/调试我的代码并逐步执行它时，我可以看到 if 语句被命中，并且更新实体字段的代码行也正在执行 - 但无论出于何种原因，它都没有设置值 ( CLIENT_nteexceeded = true or false) 直到我第二次触发它。如果它根本不更新实体记录值会更有意义，而且我错过了某种类型的“更新”消息（我玩过 service.Entity.Update() 但它似乎没有应用到这个插件）
我对 CRMDEV 还是比较陌生，所以请原谅这个愚蠢的问题。这对我来说似乎是一个非常愚蠢的问题，而且它一定是我错过的一些小问题。关于为什么这会迫使我触发两次代码以执行更新的任何想法？
这是插件步骤的配置。这三个过滤器属性是代码中引用的那些。同样，插件工作正常，只是不会每次都更新记录。

【问题讨论】：
-
只是一个疯狂的猜测。尝试将执行管道作为 PreOperation 而不是 PreValidation 并查看..
-
感谢@ArunVinoth。我不知道为什么，但是当我更新我的步骤以使用 PreOperation（或其他任何东西）时，我开始在 CRM 中遇到错误。我想我必须注销并重新注册整个事情才能更改执行管道？奇怪，但我昨天正在尝试这个确切的东西，并遇到了同样的问题。我今天不得不删除并重新添加，但没有将其切换到 PreOp。我将在重新删除后立即尝试
-
是的，只是重新添加了插件并将其设置为 PreOperation，它仍然表现出相同的行为。多么令人沮丧！我不知道为什么这个东西不会触发更新，除非它第二次执行插件....
-
在您的问题中尽量简洁...当您寻求帮助时，少即是多。
-
感谢@Daryl 的建议。我总是试图平衡提供足够的信息和太少的信息。我觉得我总是必须在问题中提供尽可能多的信息，以便为那些善意提供帮助的人描绘整个画面。以后我会努力删掉多余的文字。
