Question

I have a password confirmation component. The user can enter the two passwords manually or can generate a pair. The generated passwords are shown in a select list. When a password is selected from the list, the two input passwords should be updated with this password. The problem is that the input password doesn’t reflect the change after a password was selected.

password confirmation component:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">

    <h:outputText value="#{eval.getString(name)}: #{mandatory ? '*' : ''}"/>   
    <h:panelGrid columns="3">               
        <h:column>
            <p:password id="psw1"
                value="#{eval.evaluateAsBean(beanName).password}" feedback="false"
                disabled="#{not enabled}" />
        </h:column>
        <h:column>
            <p:commandButton value="#{label.create}" disabled="#{not enabled}"
                action="#{eval.evaluateAsBean(beanName).generate}"
                update="generated">
            </p:commandButton>
        </h:column>
        <h:column>
            <p:selectOneMenu id="generated"
                disabled="#{not enabled}"
                value="#{eval.evaluateAsBean(beanName).selectedPassword}">
                <f:selectItems value="#{eval.evaluateAsBean(beanName).passwords}"
                    var="val" itemLabel="#{val}" itemValue="#{val}" />
                    <p:ajax listener="#{eval.evaluateAsBean(beanName).passwordChanged}"
                        update="psw1, psw2" />
            </p:selectOneMenu>
        </h:column>
        <h:column>
            <p:password id="psw2"
                value="#{eval.evaluateAsBean(beanName).confirmedPassword}"
                feedback="false" disabled="#{not enabled}" />
        </h:column>
        <h:column>
            <h:outputText value="" />
        </h:column>
        <h:column>
            <h:outputText value="" />
        </h:column>
    </h:panelGrid>
</ui:composition>

passwordChanged listener:

public void passwordChanged() {
    this.password = selectedPassword;
    this.confirmedPassword = selectedPassword;
}

Edit1

I have removed the update attribute from p:ajax and changed passwordChanged listener to:

public void passwordChanged() {
    this.password = selectedPassword;
    this.confirmedPassword = selectedPassword;
    RequestContext.getCurrentInstance().update("form:tabs:editorsGroup:editor:psw1");
    RequestContext.getCurrentInstance().update("form:tabs:editorsGroup:editor:psw2");
}

With Firebug the id of psw1 is: form:tabs:9:editorsGroup:4:editor27:psw1. Still doesn’t work.

For obvious security reasons, the <p:password> (and <h:inputSecret>) do by default not redisplay the value from the model.

To turn off this security feature, set redisplay="true" (this applies to <h:inputSecret> as well).

<p:password ... redisplay="true" />
