Available since OmniFaces 1.1

The <o:validateAll> validates if ALL of the given UIInput components have been filled out. One could of course also just put required="true" on all of those UIInput components, but sometimes it's desireable to invalidate all of those fields and/or to have just only one message for it, which isn't possible with the standard Faces API.

The default message is

{0}: Please fill out all of those fields

For general usage instructions, refer ValidateMultipleFields documentation.


Please fill out all of those fields

Demo source code
    <h3>Please fill out all of those fields</h3>
    <o:validateAll id="all" components="foo bar baz" />

    <h:panelGrid columns="3">
        <o:outputLabel for="foo" value="Foo" />
        <h:inputText id="foo" />
        <h:message for="foo" />

        <o:outputLabel for="bar" value="Bar" />
        <h:inputText id="bar" />
        <h:message for="bar" />

        <o:outputLabel for="baz" value="Baz" />
        <h:inputText id="baz" />
        <h:message for="baz" />

        <h:panelGroup />
        <h:commandButton value="submit">
            <f:ajax execute="@form" render="@form" />
            <h:message for="all" />
            <h:outputText value="OK!" rendered="#{facesContext.postback and not facesContext.validationFailed}" />
