Primefaces subtale コンポーネントを使用してデータをグループ化しようとしているときに、問題に直面しています。私の列はグループ化されていますが、最初の結果は以下のスクリーンショットに示すように同じ行のままです:

ここに画像の説明を入力

通常ならAIR以外にもあるはずです。しかし、これは私が得た結果です。何が起こっているのかを理解するのを手伝ってくれる人がいますか。私は PrimeFaces ショー ケースに従い、このサブテーブルを生成するクラスを開発しました。

これはマネージド Bean です。

package tg.moov.imereport.mbean;

import java.util.ArrayList;
import java.util.List;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.inject.Named;
import tg.moov.imereport.service.DownStream;
import tg.moov.imereport.service.DownStreamTotal;

@Named
@Stateless
public class GroupedDataMBean {

    @EJB private DownStreamMBean ds;
    @EJB private DownStreamTotalMBean dst;
    private Period period = new Period();
    private List<GroupedDownStream> downStreams;

    /**
     * @return the period
     */
    public Period getPeriod() {
        return period;
    }

    /**
     * @param period the period to set
     */
    public void setPeriod(Period period) {
        this.period = period;
    }        

    public GroupedDataMBean() {

    }

    /**
     * 
     */
    public void populateDownStreams() {
        downStreams = new ArrayList<GroupedDownStream>();
        for (DownStream d : ds.getDownStreamsService()) {
            GroupedDownStream gds = new GroupedDownStream();
            gds.setDownStream(d.getIDDownStream());
            dst.setPeriod(period);
            for(DownStreamTotal dt : dst.displayGroupedDataByDownStream(d)) {
                gds.getDownStreamsDetails().add(dt);
            }
            downStreams.add(gds);
        }
    }

    /**
     * 
     * @return a List of GroupedDownStream
     */
    public List<GroupedDownStream> getGroupedDownStreams() {
        return downStreams;
    }

}

これはマスタークラスです:

package tg.moov.imereport.mbean;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import tg.moov.imereport.service.DownStreamTotal;


public class GroupedDownStream implements Serializable {
    private String downStream;
    private List<DownStreamTotal> downStreamsDetails;

    /**
     * @return the downStream
     */
    public String getDownStream() {
        return downStream;
    }

    /**
     * @param downStream the downStream to set
     */
    public void setDownStream(String downStream) {
        this.downStream = downStream;
    }        

    /**
     * @return the downStreamsDetails
     */
    public List<DownStreamTotal> getDownStreamsDetails() {
        return downStreamsDetails;
    }

    /**
     * @param downStreamsDetails the downStreamsDetails to set
     */
    public void setDownStreamsDetails(List<DownStreamTotal> downStreamsDetails) {
        this.downStreamsDetails = downStreamsDetails;
    }

    public GroupedDownStream() {
        downStreamsDetails = new ArrayList<DownStreamTotal>();
    }
}

私はそれについて何かを見つけました。これは Primefaces のバグです。代わりに、ネストされたデータブルを使用することをお勧めします。
