PrimeFaces dataTable: how to catch rows-per-page event?

Question

I cretated a PrimeFaces dataTable:

Answer 1

I posted this solution to another question, and I'm sharing it because I hope someone might find it simpler to implement than Daniel's (which still taught me a lot about JQuery!)

My solution is using Primefaces 5.2.x.

I found a pretty easy way to implement this, one of the problems I had was that when the onPaginate() method was called, it didn't have the newest selected value.

So here's what I did to make sure you always had the latest value and could save/load it to the database or a cookie or something (we save to a cookie).

        .....
        
        .....

and then our controller looks like this:

@Dependent
@Named
public class TableController implements Serializable {
    private String rowsPerPage = "25"; //default value
    .....
    public void onPaginate() {
        //save to the cookie
    }
    .....
}

Basically the magic happens in the remoteCommand, which will fire after the ajax event to insure that controller.rowsPerPage has been properly updated.
