Why are you using a PL for that? That sounds like simple page<->managed
bean operation.
public class Foo {
@PostConstruct
public void init() {
// do stuff
}
public String getOneOfManyFormValues() {
// for example
}
public String saveData() {
// update model/persist data
return null; // or ""
}
}
Something like that (coded entirely in my webmail client, so be careful ;)?
