Primefaces 对话框 + 命令按钮 [英] Primefaces dialog + commandButton
问题描述
我正在尝试将素面
I'm trying to use primefaces <p:dialog> combined with <p:commandButton>. In my .xhtml page I have a picklist and commandButton which is used to show a dialog. Dialog displays datatable with target values from picklist. Dialog has two buttons: cancel and submit. My problem is that submit button is not fired. What's strange, commandButton out of dialog works.
这是我的 .xhtml:
Here's my .xhtml:
<body>
<ui:composition template="./../resources/mainTemplate.xhtml">
<ui:define name="content">
<h:form>
<p:dialog id="dlg" header="#{messages.chooseSkillLevel}" widgetVar="dlg" modal="true" dynamic="true">
<h:dataTable value="#{editSkills.skillsAndLevels}" var="skillslevel">
<h:column>
#{skillslevel.skill.umiejetnosc}
</h:column>
<h:column>
<p:selectOneMenu value="#{skillslevel.level}" >
<f:selectItems value="#{editSkills.levels}" var="level" itemLabel="#{level.stopien}" itemValue="#{level.id}" />
</p:selectOneMenu>
</h:column>
</h:dataTable>
<p:commandButton value="#{messages.confirm}" action="#{editSkills.showSkillsAndLevels}" oncomplete="dlg.hide();" /> THIS BUTTON IS NOT FIRED
<p:commandButton value="#{messages.cancel}" onclick="dlg.hide()"/>
</p:dialog>
<p:pickList value="#{editSkills.skills}" var="skill" effect="none"
itemValue="#{skill.id}" itemLabel="#{skill.umiejetnosc}"
showSourceFilter="true" showTargetFilter="true" filterMatchMode="contains"
addLabel="#{messages.add}" removeLabel="#{messages.remove}" removeAllLabel="#{messages.removeAll}" >
<f:facet name="sourceCaption">#{messages.skillsList}</f:facet>
<f:facet name="targetCaption">#{messages.yourSkills}</f:facet>
<p:ajax event="transfer" listener="#{editSkills.onTransfer}" />
<p:column style="width:100%;">
#{skill.umiejetnosc}
</p:column>
</p:pickList>
<p:commandButton value="#{messages.confirm}" action="#{editSkills.afterSubmit}" update="dlg" oncomplete="dlg.show()" /> THIS BUTTON WORKS FINE
<p:commandButton value="#{messages.cancel}" action="profile" immediate="true"/>
</h:form>
</ui:define>
</ui:composition>
</body>
我已经标记了工作按钮而不是工作按钮.我需要做什么才能让它工作?
I've marked working button and not working one. What do I have to do to make it working?

将
Bring the
<p:dialog/>outside of the general<h:form/>and put an<h:form/>inside it instead
<p:dialog id="dlg" header="#{messages.chooseSkillLevel}" widgetVar="dlg" modal="true" dynamic="true">
<h:form>
<h:dataTable value="#{editSkills.skillsAndLevels}" var="skillslevel">
<h:column>
#{skillslevel.skill.umiejetnosc}
</h:column>
<h:column>
<p:selectOneMenu value="#{skillslevel.level}" >
<f:selectItems value="#{editSkills.levels}" var="level" itemLabel="#{level.stopien}" itemValue="#{level.id}" />
</p:selectOneMenu>
</h:column>
</h:dataTable>
<p:commandButton value="#{messages.confirm}" action="#{editSkills.showSkillsAndLevels}" oncomplete="dlg.hide();" /> THIS BUTTON IS NOT FIRED
<p:commandButton value="#{messages.cancel}" onclick="dlg.hide()"/>
</h:form>
</p:dialog>
将 appendToBody="false" 添加到 <p:dialog/> 以确保对话框在 DOM 中的 html 表单中呈现自动重定位到 HTML 正文的末尾.但这可能会导致在各种浏览器中呈现不一致.
Add appendToBody="false" to the <p:dialog/> to ensure the dialog is rendered within the html form in the DOM instead of being auto-relocated to end of HTML body. But this may cause inconsistent rendering in various browsers.
