CUBA component - Wizard

This application component let's you create UI wizards through a specific UI component DSL.

A UI wizard should be used in case of:

• multi step input
• complex decision workflows
• the user needs to be guided through the process

For more information on this topic see: http://ui-patterns.com/patterns/Wizard

Installation

1. wizard is available in the CUBA marketplace
2. Select a version of the add-on which is compatible with the platform version used in your project:

Platform Version	Add-on Version
7.2.x	0.6.x - 0.8.x
7.1.x	0.5.x
7.0.x	0.4.x
6.10.x	0.3.x
6.9.x	0.2.x
6.8.x	0.1.x

The latest version is:

Add custom application component to your project:

• Artifact group: de.diedavids.cuba.wizard
• Artifact name: wizard-global
• Version: add-on version

dependencies {
  appComponent("de.diedavids.cuba.wizard:wizard-global:*addon-version*")
}

Using the application component

Add the XML namespace wizard to the window tag of your screen like this:

    <window xmlns="http://schemas.haulmont.com/cuba/window.xsd"
        xmlns:wizard="http://schemas.diedavids.de/wizard/0.2/wizard-component.xsd">

Then add your wizard component to the screen:

<wizard:wizard id="wizard">
    <wizard:tab
      id="step1Tab"
      caption="msg://step1"
      icon="font-icon:ADN"
      spacing="true"
      margin="true">
        <button id="checkBtn" icon="font-icon:CHECK" />
    </wizard:tab>
    <wizard:tab
      id="step2Tab"
      caption="msg://step2"
      icon="font-icon:ADN">
        <button id="check2Btn" icon="font-icon:CHECK" />
    </wizard:tab>
</wizard:wizard>

The Wizard as well as its Tabs have the same attributes available as the ones from the TabSheet component of CUBA, as the Wizard component is just a specialized version of the TabSheet component.

The Wizard has particular subscription methods, that can be used in order to programmatically interact with the Wizard component. Here is an example of those:

@UiController("ddcw_SimpleWizard")
@UiDescriptor("simple-wizard.xml")
public class WizardTestScreen extends Screen {

    @Inject
    protected Wizard wizard;
    @Inject
    protected Notifications notifications;

    @Subscribe("wizard")
    protected void onCancelWizardClick(
        WizardCancelClickEvent event
    ) {
        
        notifications.create(NotificationType.TRAY)
            .withCaption("Wizard cancelled")
            .show();
    }

    @Subscribe("wizard")
    protected void onWizardStepPreChangeEvent(
        WizardTabPreChangeEvent event
    ) {

        notifications.create(NotificationType.TRAY)
            .withCaption("Tab will be changed unless `event.preventTabChange();` is called in here")
            .show();
    }

    @Subscribe("wizard")
    protected void onWizardStepChangeEvent(
        WizardTabChangeEvent event
    ) {
        notifications.create(NotificationType.TRAY)
            .withCaption("Tab has changed")
            .show();
    }

    @Subscribe("wizard")
    protected void onFinishWizardClick(
        WizardFinishClickEvent event
    ) {

        notifications.create(NotificationType.TRAY)
            .withCaption("Wizard finished")
            .show();
    }

}

Update from 0.6.x to 0.8.x

Please note, that version 0.8.x is not compatible with previous versions of the wizard addon. In order to support the CUBA 7 based Screen APIs, various breaking changes were introduced.

Mainly the underlying idea that step frames are particular types of Frames is no longer true. Steps were replaced with Tabs, which are just Component Containers just like in the TabSheet / Accordion component. That being said, it is still possible to support Fragments (the CUBA 7 equivalent of Frames) within a Tab.

The following steps have to be performed in order to update from 0.6.x to 0.8.x:

1. change wizard namespace in XML to new value: xmlns:wizard="http://schemas.diedavids.de/wizard/0.2/wizard-component.xsd"
2. change wizard:step to wizard:tab
3. inline content of all step frames into the UI descriptor that defines the wizard.
4. replace hook methods onActivate, preClose with the corresponding method subscriptions on the wizard itself.

For further information on how to use the new API, see the following example usage section.
