问题出在" p:ajax event =" rowDblselect"听者="#{companyBean.update()}" ...",当我第一次双击时,方法"更新()"被称为一次(完美!),但之后我按下commandButton" button1"然后我再次双击组件,"更新()"被称为2次。当我再重复一次时,"更新()"被称为3次...... ...... 这很奇怪!!我想当我使用commandButton更新数据表时,ajax事件会保持自身的升级。我不知道(?)......有人能帮我解决吗?

<h:panelGrid id="panel" columns="5">
  <p:commandButton id="button1"  value="Search" actionListener="#{                     
     companyBean.search()}" update="dataTable"/>          
</h:panelGrid>

<p:dataTable id="dataTable" var="companyTO" value="#{companyBean.companiesTO}"                      
  selection="#companyBean.selectedCompanyTO}" rowKey="#{companyTO}"                   
  emptyMessage="" selectionMode="single" >   

 <p:ajax event="rowDblselect" listener="#{companyBean.update()}" immediate="true"   
        process="@this" />

 <p:column >

     ...
<p:dataTable>

obs。:当我删除&#34; update =&#34; dataTable&#34;时,&#34; event =&#34; rowDblselect&#34;&#34;工作完美,只召唤一次方法。所以,问题在于更新。

答案 0 :(得分:1)

尝试删除immediate事件的ajax属性,并在commandbutton中添加属性:

process="@this" partialSubmit="true" ajax="true"

Somethig喜欢这样:

事件:

   <p:ajax event="rowDblselect" listener="#{companyBean.update()}" process="@this" partialSubmit="true" />

按钮:

 <p:commandButton id="button1"  value="Search" actionListener="#{                     
         companyBean.search()}" update="dataTable" process="@this" partialSubmit="true" ajax="true"/>
