我正在使用icefaces api項目工作，我遇到了一個問題我在dataTable裏面使用了一個commandButton刪除行中的對象，但是當我點擊它時，服務器掛起並保持加載時不顯示控制檯中的任何錯誤。頁面在命令按鈕操作後在數據表中掛起
使用Apache，Tomcat的7.0.75
我的html代碼：
<ui:composition template="./WEB-INF/template/template.xhtml">
<ui:param name="titre" value="Liste de Comptes"/>
<ui:define name="content">
<f:view>
<h:form id="form">
\t \t \t <ace:dataTable id="cptTable" value="#{compte.allComptes}"
\t \t \t \t var="cpt" paginator="true" paginatorPosition="bottom" rows="10">
\t \t \t \t
\t \t \t \t ...
\t \t \t \t
\t \t \t \t <ace:column width="10">
<f:facet name="header">
<h:outputText value="Opérations"/>
</f:facet>
<h:commandLink id="dlt" actionListener="#{compte.deletCompte}" title="Supprimer" >
<f:param name="idcpt" value="#{cpt.id_compte}"/>
<ace:ajax execute="dlt" render="form"/>
<br/>
</h:commandLink>
<h:link outcome="modifierCompte" value="Modifier le compte" >

</h:link>
<ice:outputText value=" | "/>

謝謝你的回答，我做了你所說的，並改變了ID的，但不幸的是，我仍然有同樣的問題 –
