Practical RichFaces, Second Edition

CHAPTER 2 GETTING STARTED
Listing 2-26. List any number of ids, each separated by a space
When using , in addition to a space, it’s also possible to separate with a comma (,) as
shown in Listing 2-27.
Listing 2-27. Example of separating ids with a comma instead of just a space
We believe using a comma is a little easier and more familiar for those who used with
RichFaces 3, but it’s really up to you.
The second difference is more important. Next, we’ll use an example to show how it works in JSF 2.
Dynamic render
To show how a dynamic render works in JSF 2, we’ll create a sample page to look like Figure 2-1.
Figure 2-1. Dynamic render with three clocks
Instead of hard coding the component to render, we are going to select which component we would
like to update. Now, being able to set the render attribute to an EL is supported by JSF 2; however, it
works slightly different when using RichFaces.
Listing 2-28 shows the JSF page.
