我有一个重复控件，其源代码为notesdocumentcollection。在重复控件内部，我有一个具有数据源的面板，数据源的文档id属性设置为单个文档的通用id，在我的例子中是重复控制变量apprDoc（apprDoc.getUniversalID）。因此，使用面板数据源，我试图将重复控件中的每个字段直接绑定到相应的后端文档。我点击了一个提交按钮，我需要将用户选择的值发布到后端文档中，并设置一些其他未绑定到后端文档的字段。我需要获取文档集合中每个文档的句柄，以便在后端文档上设置字段值。有人可以建议一种方法来做同样的事情，或任何其他方式来实现我想要实现的功能。请在下面找到相同的代码：

使用简单操作“保存数据源”的按钮怎么样？这应该保存XPage上可用的所有数据源。

重复元素的计算效率不高 - JSF生命周期将使您查找值两次。你可以试试这个：
// If we looked them up before we don't need to do anything
if (viewScope.approveIDs) {
return viewScope.approveIDs;
}
// Look up the employee details view to get the employee appraisal details from the current database
var curDB:NotesDatabase = session.getCurrentDatabase();
var vwlkApprView:NotesView = curDB.getView("vwlkAllApprApper");
var collDocAppr:NotesViewEntryCollection = vwlkApprView.getAllEntriesByKey(sessionScope.EmployeeID);
// Don't do a count, slow!
var result = new java.util.Vector();
// Add all unids
var ve:NotesViewEntry = collDocAppr.getFirstEntry();
while (ve != null) {
var nextVe = ve.getNextEntry(ve);
result.add(ve.getUniversalId()); // eventually check to avoid categories?
ve.recyle();
ve = nextVe;
}
viewScope.approveIDs = result.isEmpty() ? null : result;
collDocAppr.recyle();
vwlkApprView.recycle();
return viewScope.approveIDs;
此代码（关闭我的内存，因此检查语法）有一些值得注意的属性：
try { } catch(e ) { }
