Using the constructor is one way. If you don't have enough
information at constructor time (references to other beans), then you
can use the jsf-spring integration library which will allow you to
have your beans implement the InitializingBean interface, and that
will allow you to call a "afterPropertiesSet" method after everything
is initialized.
Another way to do this is execute some code when your list is rendered.
Ie, if your page has a <h:dataTable binding="page.dataTable">, then
you can initialize some things in "page.getDataTable()." I personally
dislike this approach as it seems like something of a hack, but it's
the only way to do it with "pure" JSF unless you have backing bean
methods that look like this
public Object getX() { initialize(); return x; }
