我有一個場景，我希望N個視圖實例在視圖上的TransparentContainer，每個接收不同的參數。爲了實現這一點，我寫了一些邏輯來動態創建cl_wd_view_container_uielement，將它添加到cl_wd_uielement_container（主視圖上的TransparentContainer），然後使用動態導航發送插件以發送我的參數。代碼可以在下面找到。將視圖的實例動態添加到TransparentContainer中
這一切都適用於一個問題：創建的實例不是唯一的，所以我基本上添加了N個相同視圖的副本。 N個插件被觸發並處理，但最後一個設置所有視圖的參數，因爲只有一個實例。該視圖的WDDOMODIFYVIEW也只能觸發一次。
下面的代碼被重新利用，並從工作版本清除，所以我知道這是可能的。最大的區別是我在我的場景中添加了來自同一個WDC的視圖。在原始應用程序中，動態添加的視圖具有自己的Web Dynpro組件，調用者還提供動態創建的組件用法。
是否有某種方法可以創建多個我缺少的實例？在這種情況下，我應該提供一個組件使用情況嗎？我一直在修補這個問題幾個小時，但沒有取得任何進展，所以我歡迎任何意見讓我走上正軌。從主視圖
