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.
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>
I've marked working button and not working one. What do I have to do to make it working?
You can try either of the following , I vote number one, it's a cleaner design IMO
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>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.
<p:commandButton value="Cancel" oncomplete="PF('yourDialogWidgedVarName').hide();" process="@this" />
Make sure to use ' when u call the widgetVar name. You can also use immediate="true" or process="@this".
