[英]Dynamics 365 CRM Online - Plugin Only Performs Update Every Other Time it is Triggered
更新我从该论坛以及Dynamics论坛中获取了一些信息，并且我的代码可以正常工作。 代码中的主要问题是我只查看了preImage，但是在大多数情况下，这三个值之一将被更新，这意味着我无法针对该特定字段的preImage。 我更改了逻辑以使用Collection属性（更新值）（如果已更新），但是使用PreImage值（如果未更新）-这使代码起作用，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-比原始代码更有效，更简洁（向下滚动以查看旧的/无效的代码）。 我还添加了一些评论，以使其更易于理解。 感谢所有人的帮助（无论是在SO上还是在Dynamics论坛上！）

原帖再回来一次！ 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错误-SCORE！ 现在，该插件可以正常运行了 ，但是仅在我触发该插件时每隔一次它才能工作。
因此，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），但是没有执行我需要的更新，直到第二次触发插件为止。 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，如果我更新了属性1，则插件不会更新我的值，如果我随后更新了属性2，插件仍然不会更新我的值，直到再次重新更新属性1或属性2为止）。 在我分析/调试代码并逐步执行代码时，我可以看到if语句被命中，并且更新了实体字段的代码行也正在执行-但由于某种原因，它没有设置值（ CLIENT_nteexceeded = true或false），直到我第二次触发它为止。 如果它根本不更新实体记录值，那将更有意义，而且我缺少某种类型的“更新”消息（我曾使用过service.Entity.Update（），但似乎没有应用于此插件）
我对CRMDEV还是比较陌生，所以请原谅这个愚蠢的问题。 对我来说，这似乎是一个非常愚蠢的问题，这肯定是我所缺少的小事情。 关于为什么这迫使我两次触发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属性。 同样，插件工作正常，只是不会每次都更新记录。

我将帮助您了解CRM执行管道的工作方式。 然后，您可以在trace / Audit / profiler的帮助下进行故障排除，以找出失败的地方。
基本上，您是在预验证/预操作阶段中，在DB事务之前拦截从CRM UI发生的service.Update()平台调用。 然后根据业务需要进行数据处理，并在目标实体本身中设置额外的属性值。 这避免了另一个显式的额外service.Update()调用并反过来循环死锁。
如果有任何异常，则您正在登录跟踪并抛出该异常。 我建议将其更改为InvalidPluginExecutionException ，您将在UI弹出窗口中看到该InvalidPluginExecutionException 。 这将回滚事务，这意味着不会保存数据。
此外，为了更好地理解-记录每个条件语句，变量值等，以查看发生问题的确切跟踪日志。
