使用XSLT宏的Umbraco導航 - 無子節點的問題

Question

我已將superfish導航菜單實施爲umbraco安裝。 Superfish只需要一個UL元素，並將其轉變爲一個分層菜單，當您將鼠標懸停在父項上方（您記得1999年它們已經很酷時，它是否正確？）。

我不明白爲什麼，在某些頁面（通常是沒有孩子的頁面），菜單不顯示任何頁面的子項目。我對XSLT的暴露很少，所以我必須忽略一些邏輯。

你可以看到實際的網站here將鼠標懸停在「個人培訓」上查看菜單的工作，現在點擊「體重管理」，嘿，發生魔術停止。

創建UL結構的XSLT位於下方，HTML頁面源告訴我它在問題發生時根本不爲子頁面生成任何LI元素。

你上面描述的問題不是我複製的（我使用Notepad ++和差異查看器檢查了你的源代碼）。我從您的代碼中看到您正在使用CogWorks的靈活導航軟件包。你能確保你使用的最新代碼是here？

非常感謝，
