Html Dialog with Multiple Views

To implement a user interaction that consists of several pages (for example a wizard), one Html Dialog can have multiple views (.xhtml files). This allows to enclose a complex user interaction in one Html Dialog and to abstract it from the business process.

How to add a view

In the New menu in the Axon.ivy project tree you find the New Html Dialog View wizard to add a view to a Html Dialog. Just enter the name of the view and the xhtml file for the view is created and added to the Html Dialog. In the ivy project tree all view files of a Html Dialog are displayed below the main node of that Html Dialog.


How to switch views during runtime

If you have created a Html Dialog with several views you have to implement the navigation between the views for the user on your own. The basic solution is a commandButton with an update attribute to load the next view.

You find an example of a multi view Html Dialog in the HtmlDialogDemos project that is provided with the Axon.ivy Designer.

<h:form id="myForm">
    <p:panel header="Multi View Demo" id="panel">
    <h3>Payment - Credit Card</h3>
    <p:messages id="msgs"/>
    <h:panelGrid columns="2">
        <p:outputLabel value="Credit Card Number"/>
        <p:inputMask required="true" value="#{data.creditCardNumber}"
            id="CreditCardNumber" mask="9999-9999-9999-9999"></p:inputMask>
    <p:commandButton value="Next" update="myForm" action="#{logic.nextView('CreditCard')}"/>
