Vaadin SpringBoot Navigator - Passing data (and reloading) between views.

Vaadin 6 / 7 / 8
1

Hey! I have the following scenario, I would like to know the best way to resolve it.
I have the configuration described on the title, Vaadin 7, SpringBoot, and a Navigator defined on the main UI class with a toolbar with buttons to switch between views.

On View #1 ) A list of items are retrieved from the database and are shown in a ComboBox.
On View #2) Users can create new items and these are persisted on the database.

When I first enter to my application, the @PostConstruct init() method is called on View #1, and the items from the database are loaded.

The problem is that when I create new items on View #2 and then I enter View #1, it does not show the items recently created on View #2, because it does not enter again the init() method (which loads the items from database)

What would be the best way to resolve this?

Thanks in advance!

You can load the database items when a user enters on view #1.
In your view:
@Override
public void enter(ViewChangeListener.ViewChangeEvent viewChangeEvent) {
// (re)load your items database
}

Thank you, I was not clear on the difference between @PostConstruct-init() and enter() methods.
