我正在尝试 自动完成演示。我没有收到任何错误，但 httprequest/response 显示它正在与服务器通信，而不是与 bean 通信。我正在使用最新版本的 primefaces 3.4。

任何帮助表示赞赏。

豆 ：

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import com.zreflect.emyed.managedbean.BaseMB;

@ManagedBean
@ViewScoped
public class CircleSearchBean extends BaseMB implements Serializable {
    private static final long serialVersionUID = 1L;
    private String selected;
    List<String> results = new ArrayList<String>();
    public List<String> complete(String query) {
        List<String> results = new ArrayList<String>();
        for (int i = 0; i < 10; i++) {
            results.add(query + i);
        }
        return results;
    }
    /**
     * @return the selected
     */
    public String getSelected() {
        return selected;
    }

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

在将“id”属性添加到自动完成后，它现在正在工作，如演示中所示。

<p:autoComplete id="autocomplete" value="#{circleSearchBean.selected}" 
   completeMethod="#{circleSearchBean.complete}"/>

在一个单独的项目中，它在没有“id”属性的情况下工作。看起来像一个错误。
