问题：寻找一些更合适的设计。<h:dataTable>和SessionScoped beans
目标：我想拥有一些用户信息的表格，并在每个用户的列中使用按钮“更改密码”，点击后：“更改密码”按钮消失（呈现=“false”）并出现inputSecreat字段 - 用户输入密码并提交（通过点击一些额外的按钮或热键）。提交后 - “更改密码”按钮如前所述。

，所以我用我的豆列在：
<h:commandButton id="chps" value="#{i18n.chpsqd_button}" rendered="#{!userSession.getPWRender(puser.id)}"
action="#{userSession.setPWrenerTrue(puser.id)}">
<f:ajax render="pswd chps"/>
</h:commandButton>
问题2：什么可能是这更好的设计情况？
问题3：如果某些组件（inputSecret在我的情况下）是否可以听取某些事件（onclick，ondbclick在组件标签内），如果它禁用= true？
谢谢！
什么是下午事件？ :) – BalusC 2010-07-30 11:48:09
