[英]Dynamics 365 CRM Online - Plugin Only Performs Update Every Other Time it is Triggered
更新我從該論壇以及Dynamics論壇中獲取了一些信息，並且我的代碼可以正常工作。 代碼中的主要問題是我只查看了preImage，但是在大多數情況下，這三個值之一將被更新，這意味着我無法針對該特定字段的preImage。 我更改了邏輯以使用Collection屬性（更新值）（如果已更新），但是使用PreImage值（如果未更新）-這使代碼起作用，並且每次都會觸發更新-不再需要觸發插件兩次！ 這是更新后的代碼-比原始代碼更有效，更簡潔（向下滾動以查看舊的/無效的代碼）。 我還添加了一些評論，以使其更易於理解。 感謝所有人的幫助（無論是在SO上還是在Dynamics論壇上！）

原帖再回來一次！ 昨天，我意識到我不使用PreImage來獲取未包含在更新的屬性集合中的值的錯誤-SCORE！ 現在，該插件可以正常運行了 ，但是僅在我觸發該插件時每隔一次它才能工作。
因此，似乎插件實際上正在觸發（我可以在“設置”>“插件配置文件”中看到插件配置文件），但是沒有執行我需要的更新，直到第二次觸發插件為止。 這似乎發生在我正在監聽的所有3個屬性上，並且每個屬性都需要更新兩次（例如，如果我更新了屬性1，則插件不會更新我的值，如果我隨后更新了屬性2，插件仍然不會更新我的值，直到再次重新更新屬性1或屬性2為止）。 在我分析/調試代碼並逐步執行代碼時，我可以看到if語句被命中，並且更新了實體字段的代碼行也正在執行-但由於某種原因，它沒有設置值（ CLIENT_nteexceeded = true或false），直到我第二次觸發它為止。 如果它根本不更新實體記錄值，那將更有意義，而且我缺少某種類型的“更新”消息（我曾使用過service.Entity.Update（），但似乎沒有應用於此插件）
我對CRMDEV還是比較陌生，所以請原諒這個愚蠢的問題。 對我來說，這似乎是一個非常愚蠢的問題，這肯定是我所缺少的小事情。 關於為什么這迫使我兩次觸發代碼以執行更新的任何想法？
這是插件步驟的配置。 這三個過濾器屬性是代碼中引用的屬性。 同樣，插件工作正常，只是不會每次都更新記錄。

我將幫助您了解CRM執行管道的工作方式。 然后，您可以在trace / Audit / profiler的幫助下進行故障排除，以找出失敗的地方。
基本上，您是在預驗證/預操作階段中，在DB事務之前攔截從CRM UI發生的service.Update()平台調用。 然后根據業務需要進行數據處理，並在目標實體本身中設置額外的屬性值。 這避免了另一個顯式的額外service.Update()調用並反過來循環死鎖。
如果有任何異常，則您正在登錄跟蹤並拋出該異常。 我建議將其更改為InvalidPluginExecutionException ，您將在UI彈出窗口中看到該InvalidPluginExecutionException 。 這將回滾事務，這意味着不會保存數據。
此外，為了更好地理解-記錄每個條件語句，變量值等，以查看發生問題的確切跟蹤日志。
