在actionListener中验证失败后，JSF 2.0禁止调用操作 [英] JSF 2.0 Forbid calling action after failed validation in actionListener

问题描述

我有一个用于添加一些数据的对话框:

 <p:commandButton id="save" 
    actionListener="#{adminNationalController.saveTeam}" 
    action="#{adminManageInternationalTournamentController.updateTeamList}"
    value="#{msg.save}" ajax="true"
    icon="ui-icon-check"
    onmousedown="return validateSubmit('addCombinedTeamForm', ['name'],'lang')"
    oncomplete="if (!args.validationFailed) addCombinedTeamDialog.hide()"
    process = "@form"
    update="lang, name, :manageTournament:dataList,:manageTournament:scroll, :menuForm:growl, :manageTournament:nationalTeam">

    <f:setPropertyActionListener 
        value="#{adminNationalController.newTeamBean}"
        target="#{adminManageInternationalTournamentController.newTeamBean}"/>

</p:commandButton> 
 

在saveTeam中，我尝试验证数据，但在action情况下，以防验证失败.

可以禁止通话吗?

解决方案

从操作侦听器中，当您想中止其余操作侦听器和最终操作的处理时，应该抛出AbortProcessingException.

但是，最好在输入组件上使用真实的Validator.这样，整个调用动作阶段将被绕过.

I have a dialog for adding some data:

<p:commandButton id="save" 
    actionListener="#{adminNationalController.saveTeam}" 
    action="#{adminManageInternationalTournamentController.updateTeamList}"
    value="#{msg.save}" ajax="true"
    icon="ui-icon-check"
    onmousedown="return validateSubmit('addCombinedTeamForm', ['name'],'lang')"
    oncomplete="if (!args.validationFailed) addCombinedTeamDialog.hide()"
    process = "@form"
    update="lang, name, :manageTournament:dataList,:manageTournament:scroll, :menuForm:growl, :manageTournament:nationalTeam">

    <f:setPropertyActionListener 
        value="#{adminNationalController.newTeamBean}"
        target="#{adminManageInternationalTournamentController.newTeamBean}"/>

</p:commandButton> 

In saveTeam I try to validate data but action case in case validation failed.

Is it posible forbid calling action?

解决方案

From an action listener, you're supposed to throw AbortProcessingException when you want to abort the processing of the remaining action listeners and the final action.

However, better would be to use a real Validator on the input component. This way the whole invoke action phase will be bypassed.
