I'm using JSF 2 with PrimeFaces 4.0.
I have a form with some inputs and validation. Some fields may automatically filled when choosing an entity from a dialog. This works fine when I choose the entity before I submit the whole form (and validate). But when I choose an entity after validation the update of the component does not work.
JSF page:
<h:form id="form">
<p:inputText id="id" value="#{bean.user.id}" required="true"
onclick="PF('usersDialog').show()" />
<p:inputText id="name" value="#{bean.user.name}" required="true"
onclick="PF('usersDialog').show()" />
<p:commandButton value="submit" action="#{bean.submit}" update=":form" />
</h:form>
<p:dialog widgetVar="usersDialog">
<h:form>
<p:dataTable value="#{bean.users}" var="user">
<p:column>
<p:commandButton value="choose" onclick="PF('usersDialog').hide()"
process="@this" action="#{bean.select(user)}" update=":form" />
</p:column>
<p:column>
<h:outputText value="#{user.name}" />
</p:column>
</p:dataTable>
</h:form>
</p:dialog>
I know its up to the JSF lifecycle, but I'm not able to fix it. So how can I update the form after validation fail when choosing an new entity from dialog?
Thanks in advance.

Exactly for this purpose, <p:resetInput>
component was introduced (based on OmniFaces ResetInputAjaxActionListener
).
Nest it inside the command button, with a target
set to the same client ID as update
attribute of command button:
<p:commandButton ... update=":form">
<p:resetInput target=":form" />
</p:commandButton>

try this way:
<h:form id="form">
<p:panel style="width: 80%;">
<p:fieldset legend="Some User" id="costAuthUser">
<p:panelGrid columns="3">
<h:outputLabel for="costUserId">User-ID</h:outputLabel>
<p:inputText id="costUserId" onclick="PF('costAuthDialog').show()"
value="#{createCert.costAuthUser.userId }" required="true"
requiredMessage="Bitte geben Sie die UserID ein." />
<p:message for="costUserId" />
<h:outputLabel for="costLastName">Name</h:outputLabel>
<p:inputText id="costLastName"
onclick="PF('costAuthDialog').show()"
value="#{createCert.costAuthUser.lastName }" />
<!-- <p:watermark value="" for="costLastName"/> -->
<p:message for="costLastName" />
</p:panelGrid>
</p:fieldset>
<p:separator />
<p:commandButton value="submit" action="#{createCert.prepareEmail }" update=":form"/>
</p:panel>
<h:form>
<p:dialog widgetVar="costAuthDialog" resizable="false" header="Some User">
<h:form id="dialogForm">
<p:dataTable value="#{createCert.costAuthList}" var="user">
<p:column>
<p:commandButton value="choose" process="@this"
oncomplete="PF('costAuthDialog').hide()" action="#{createCert.selectCostAuth(user) }" update=":form"/>
</p:column>
<p:column headerText="Name">
<h:outputText value="#{user.lastName}" />
</p:column>
<!-- Some more -->
</p:dataTable>
</h:form>
</p:dialog>
i think there's some issue re-rendering dialog hierarchies, this way dialog does not get updated.
and you should use oncomplete="PF('costAuthDialog').hide()"
instead of onclick
