Wizard Figure 21.1 Just by looking at the Wizard the user can see what he will be asked to provide, how he can navigate between the pages and how to complete or cancel the process. Since the Wizard itself is basically just a normal View , it will respond to the openModal call. Let's imagine a button that opens the Wizard: button("Add Customer").action { find { openModal() } } Page navigation By default, the Back and Next buttons are available whenever there are more pages either previous or next in the wizard. For Next navigation however, whether the wizard actually navigates to the next page is dependent upon the completed state of the current page. Every View has a completed property and a corresponding isCompleted variable you can manipulate. 270
Wizard When the Next or Finish button is clicked, the onSave function of the current page is called, and the navigation action is only performed if the current page's completed value is true . Every View is completed by default, that's why we can navigate to page number two without completing page one first. Let's change that. In the BasicData editor, we override the onSave function to perform a partial commit of the name and type fields, because that's the only two fields the user can change on that page. override fun onSave() { } isComplete = customer.commit(customer.name, customer.type) The commit function now controls the completed state of our wizard page, hence controller whether the user is allowed to navigate to the address page. If we try to navigate without filling in the name, we will be granted by the validation error message in Figure 21.2: Figure 21.2 We could go on to do the same for the address editor, taking care to only commit the editable fields: override fun onSave() { } isComplete = customer.commit(customer.zip, customer.city) 271
