Question

我尝试在复合组件中使用标签<ace:datatable>主要是效果很好。我想从表中获取行数据以在bean中使用它，但是当我单击该行时，我收到错误消息

内部服务器错误

~~我需要你的帮助（BalusC :)）来修复这个错误。~~

这是我的组成部分：

组件支持bean

import java.io.IOException;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.List;
import java.util.Locale;
import java.util.ResourceBundle;
import javax.faces.application.FacesMessage;
import javax.faces.component.FacesComponent;
import javax.faces.component.NamingContainer;
import javax.faces.component.UIInput;
import javax.faces.component.html.*;
import javax.faces.component.UINamingContainer;
import javax.faces.context.FacesContext;
import javax.faces.component.UIData;
import org.icefaces.ace.model.table.RowStateMap;

@FacesComponent("partnercard")
public class partnercard extends UINamingContainer implements Serializable {

    private RowStateMap stateMap = new RowStateMap();
    private List<PartnerData> partnersList = new ArrayList<PartnerData>();
    private UIData partnersTable; // поиск партнера - таблица со списком партнеров

    @Override
    public String getFamily() {
        return UINamingContainer.COMPONENT_FAMILY;
    }

    public void encodeBegin(FacesContext context) throws IOException {
        super.encodeBegin(context);
    }

    public UIData getPartnersTable() {
        return partnersTable;
    }

    public void setPartnersTable(UIData partnersTable) {
        this.partnersTable = partnersTable;
    }

    public RowStateMap getStateMap() {
        return stateMap;
    }

    public void setStateMap(RowStateMap stateMap) {
        this.stateMap = stateMap;
    }

    public List<PartnerData> getPartnersList() {
        return partnersList;
    }

    public void setPartnersList(List<PartnerData> partnersList) {
        this.partnersList = partnersList;
    }
}

这是PartnerData.java

import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;

public class PartnerData implements Serializable {

    private long id = 0;
    private String name = "";

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }
}

ace：复合组件内的数据表在JSF中不起作用
