onChange事件未在XPAGE重复控制中发射

Question

特里，您需要重新审视架构。如果在提交时处理更新，那么为什么不愿将它们单独发送到服务器 - 正如蒂姆（Tim）很好地指出的那样。我会做什么：

创建2个Java类：一个“订单”一个“ lineItem”
让订单类实现地图接口地图
将订单类用于重复控制（它将为您提供每个LineItem的键，作为重复变量）
将重复中的字段绑定到订单[retoke] .fieldName
在对象数据源中使用订单
在订单类中实现保存方法，并在对象数据源的保存方法中调用它

非常划算，让我知道您是否需要我详细说明。 Java Collections框架是您的朋友。

它比看起来容易：

   public class LineItem {

private String unid;
private String partno;
private int quantity;
private long unitprice;

/**
 * Constructor for new items
 */
public LineItem() {
    this.unid = null;
}

/**
 * Constructor for existing items
 */
public LineItem(Document doc) {
    this.unid = doc.getUniversalId();
    // more here
}


/**
 * @return the unid
 */
public String getUnid() {
    return this.unid;
}

/**
 * @return the partno
 */
public String getPartno() {
    return this.partno;
}
/**
 * @param partno the partno to set
 */
public void setPartno(String partno) {
    this.partno = partno;
}
/**
 * @return the quantity
 */
public int getQuantity() {
    return this.quantity;
}
/**
 * @param quantity the quantity to set
 */
public void setQuantity(int quantity) {
    this.quantity = quantity;
}
/**
 * @return the unitprice
 */
public long getUnitprice() {
    return this.unitprice;
}
/**
 * @param unitprice the unitprice to set
 */
public void setUnitprice(long unitprice) {
    this.unitprice = unitprice;
}

public void save(Database db) {
    Document doc = null;
    if (this.unid == null) {
        doc = db.createDocument();
        doc.replaceItem("Form", "LineItem");
    }
    doc.replaceItem("PartNo", this.partno);
    // More here
    doc.save();
}
}

对于订单 - 假设您从文档集合中加载。

public class Order implements Map<String, LineItem> {

// You might want to have a stack here to keep order
private final Map<String, LineItem> backingMap          = new LinkedHashMap<String, LineItem>();
private final Set<String>           deletedItemKeys     = new HashSet<String>();

// The key we use for new items when unid is null
private int                         lastNewItemNumber   = 0;

@Override
public int size() {
    return this.backingMap.size();
}

@Override
public boolean isEmpty() {
    return this.backingMap.isEmpty();
}

@Override
public boolean containsKey(Object key) {
    return this.backingMap.containsKey(key);
}

@Override
public boolean containsValue(Object value) {
    return this.backingMap.containsValue(value);
}

@Override
public LineItem get(Object key) {
    return this.backingMap.get(key);
}

@Override
public LineItem put(String key, LineItem value) {
    // Here it gets a little special
    // We need to prevent null keys
    if (key == null) {
        key = String.valueOf(this.lastNewItemNumber);
        lastNewItemNumber++;
    }
    this.deletedItemKeys.remove(key);
    return this.backingMap.put(key, value);
}

@Override
public LineItem remove(Object key) {
    this.deletedItemKeys.add(key.toString());
    return this.backingMap.remove(key);
}

@Override
public void putAll(Map<? extends String, ? extends LineItem> m) {
    for (Map.Entry<? extends String, ? extends LineItem> me : m.entrySet()) {
        this.put(me.getKey(), me.getValue());
    }
}

@Override
public void clear() {
    this.deletedItemKeys.addAll(this.backingMap.keySet());
    this.backingMap.clear();
}

@Override
public Set<String> keySet() {
    return this.backingMap.keySet();
}

@Override
public Collection<LineItem> values() {
    return this.backingMap.values();
}

@Override
public Set<java.util.Map.Entry<String, LineItem>> entrySet() {
    return this.backingMap.entrySet();
}

public void load(NotesDocumentCollection dc) throws NotesException {
    Document doc = dc.getFirstDocument();
    Document nextDoc;
    while (doc != null) {
        nextDoc = dc.getNextDocument(doc);
        LineItem li = new LineItem(doc);
        this.put(doc.getUniversalId(), li);
        doc.recycle();
        doc = nextDoc;
    }

    doc.recyle();
}

public void save(Database db) {
    for (LineItem item : this.backingMap.values()) {
        item.save(db);
    }

    // Now kill the left overs - needs error handling
    for (String morituri : this.deletedItemKeys) {
        Document delDoc = db.getDocumentByUnid(morituri);
        if (delDoc != null) {
            delDoc.remove(true);
        }
    }       
}
}
