Heres one I do in a loop. See how the parameters defines two parameters

My listener looks like this
@InjectPage("MarriagePage")
public abstract MarriagePage getMarriagePage();
public MarriagePage doMarriage(Integer spouseId, Short mno) {
Marriage marriage = getMarriage();
if (getPerson().getGender().isMale()) {
marriage.setHusband(getPerson().getId());
marriage.setWife(spouseId);
} else {
marriage.setWife(getPerson().getId());
marriage.setHusband(spouseId);
}
marriage.setM_no(mno);
MarriagePage marriagePage = getMarriagePage();
marriagePage.setFunction(Function.EDIT);
return marriagePage;
}
The getMarriage() and getPerson functions are retrieving a session scoped
application state objects which have been populated by @Textfields on this
current page.
