CRM 2011工作流程中的DynamicActivity驗證錯誤

我正在構建自定義潛在客戶資格認證的工作流程。我在CRM中構建了一個工作流程，並且正在調用通過引導參考作爲輸入參數的自定義工作流活動，並且我期望創建的帳戶的引用作爲返回參數。CRM 2011工作流程中的DynamicActivity驗證錯誤

的代碼是：

爲什麼發生這種情況的任何想法？這似乎很普通的代碼我

你沒有分配任何東西給出參數。下面一行在你的代碼中被註釋掉了：'accountRef.Set（executionContext，new EntityReference（「account」，accountId））;' – Scorpion

我評論過它，因爲我認爲這是一個問題。我刪除了評論斜線，錯誤仍然存在。我已經更新了問題中的代碼。 – MaPi

您是否嘗試過調試代碼活動以檢查其下降的位置？ – Scorpion

在參數定義你有InOutArgument裝飾只有輸入屬性

[Input("EntityReference leadIn")] 
[ReferenceTarget("lead")] 
public InOutArgument<EntityReference> LeadReference { get; set; }

更改類型InArgument

public InArgument<EntityReference> LeadReference { get; set; }

將解決這個問題。
