Question

= “”

我使用 p：repeat

创建滑雪者列表

<p:repeat value="#{skiingBean.listSkierCompetitionsByRefCompetition(competition.competitionId)}" var="skier">
	<hr />
	<h:panelGrid columns="2" style="width:100%">
		<p:column>
			<h:outputLink value="DisplayImage?Image_id=#{skier.skier.photo.photoId}" target="_blank" >
			                       			<h:graphicImage value="DisplayImage?Image_id=#{skier.skier.photo.photoId}" width="50" height="50"></h:graphicImage>
			</h:outputLink>
		</p:column>
		<p:column>
			<h:panelGrid columns="2" style="width:100%">
			    <h:outputText value="Name: " style="color:#000000;font-size: 11px;display: flex"/>
			    <h:outputText value="#{skier.skier.skierFullName}" style="font-size: 10px;display: flex"/>
			                    			
			    <h:outputText value="Profession: " style="color:#000000;font-size: 11px;display: flex"/>
			    <h:outputText value="#{skier.skier.skierProfession}" style="font-size: 10px;display: flex"/>
			                    			
			    <h:outputText value="Score: " rendered="#{competition.status.statusId == 1}" style="color:#000000;font-size: 11px;display: flex"/>
			    <p:spinner id="aaa" value="#{skiingBean.skierScore}" style="font-size: 10px;display: flex;width : 150px; height:25px" />
			    <p:commandButton value="Give Score"
				             ajax="false" update="@all"
		     		             actionListener="#{skiingBean.giveScore(skiingBean.skierScore, skier.skier.skierId, competition.competitionId)}"/>
			</h:panelGrid>
		</p:column>
	</h:panelGrid>
</p:repeat>

方法 giveScore 是：

public void giveScore(int score, int skierId, int competitionId) 
{
    SkierCompetition sc = new SkierCompetition();
    sc = eDao.findSkierCompetitionssByRafSkierAndRefCompetition(skierId, competitionId);
    sc.setSkierCompetitionScore(score);
    eDao.updateSkierCompetition(sc);
}

我的问题是，如果我将分数添加到第一个或第二个滑雪者并且点击“给予分数”按钮后，我获得了一个空值。 但是，当我影响到最后一名滑雪者的分数时，没关系，我得到了像Screenshot那样的分数。

请你解决这个问题。非常感谢。
