My .xhtml page is:

...         


        

Answer 1

I would do it without any JavaScript. Primefaces's datatable has a first attribute, which is the index of the first data to display.

And your backing bean:

public class CalculatePageTable {
    private int first = 1;

    public int getFirst(){
        return first;
    }

    public void addRow(){
        // 1. your stuff for adding the row 
        ...
        // 2. switch to the row
        first = getFirstRowOnLastPage(); 
    }

    private int getFirstRowOnLastPage(){
        ...
    }
}
