獲取XForm中重複單選按鈕的值

Question

我在XForms中有重複問題。我需要訪問循環內的單選按鈕字段的一些值。如果單選按鈕選擇了特定的值，範圍就是使輸入文本可見。我想要所有重複的這種行爲（單選按鈕和輸入文本字段在循環內）。

它工作正常一行，但是當我添加一個新行，代碼不能正常工作了。

我複製一個簡單的例子來檢查這個行爲：

如果這個代碼在Orbeon服務器上運行，它工作得很好，直到我們在「重複」元素添加一個新行。然後，無論在單選按鈕中選擇的值如何，輸入字段消失（或不可見）。

我想象中，加入該行的副本，將可能有相同的元素的名稱（或更改原始元素的名稱），並導致此問題。但我需要訪問每行的單選按鈕的值。可能嗎？這是一個已知的錯誤嗎？如何實現這一目標？

Answer 1

可以使用相對路徑元素，而不是綁定變量來引用元素值重複之內，所以你的情況：

替換：

($element-1-1-2='yes') 

與

(../element-1-1-2='yes') 

另請參見orbeon calculated fields in a repeat break after first itiration

這不起作用重複之外;我不確定你在第二個元素-1-1-2條件中的預期邏輯。
