Popup from Popup

There are many ways on how to launch a popup from a popup, and I'm going to demonstrate here a "backingBean-based" of launching this.

So why go programmatic? The reason for this is because most of the time, I would prefer launching one popup at a time, meaning  that when I call the second popup, I first make sure to close the current popup.

So a straight forward sample in launching the popup declaratively looks like this.

As you might already know, this is achieved by simply calling af:showPopupBehavior.

Now let's go for the programmatic approach in making sure we first close the current popup before launching a 2nd one. As I have already mentioned, there are different ways of achieving this without binding your popup to a bean by using javascript for example (see Invoke popup from a popup by Luc Bors ).

Modeling a Cascading DropDown

Here's a quick step-by-step tutorial on how to model a 3 level cascading dropdown combobox.

Requirements:

• HR Schema
• ReadOnly viewObject for Countries, Locations and Departments 

Model

You'll need to set viewCriterias on:

• Location filtered by CountryId
• Department filtered by LocationId

Create a viewObject that will utilize these models.

Sample viewObject

Add an lovModel for CountryId, LocationId and DepartmentId.

Country Attribute

Location Attribute

Test your ApplicationModule

And everything in the UI is just a matter of drag-and-drop and setting autosubmit on the selectOneChoice and partialTrigger on those component that has dependencies.
