Post-injection hook (or how to avoid injection races?)

[thatrichard]

Consider this component

@Name("personEditor")
@Stateful
@Scope(ScopeType.CONVERSATION)
@Conversational
public class PersonEditorBean implements PersonEditor {

 @In
 private Person person;

 @In
 public void setTitle(String title) {
 //modify the title
 person.setTitle(title);
 }

This code will only work when "Person" is injected before "Title". What I think I need to do is to modify the setTitle method to store the value in a proxy and invoke another method, post-injection, to handle the modification, i.e.

 @In
 private Person person;

 private String titleProxy;

 @In
 public void setTitle(String title) {
 titleProxy = title;
 }

 private void updateTitle() {
 //modify titleProxy
 person.setTitle(titleProxy);
 }

For this to work I need a way of invoking the "updateTitle" method after injection, i.e. a post-injection hook. I am sure Seam supports something like this, but I'm not finding it.

Can someone point me in the right direction?

I can't see why you need a setTitle method if the title is already provided by the person object.

Hi Michael

I need the setTitle method because the title needs to be modified before being set. (I tried to indicate this with //modify the title.)

Ultimately, I'm trying to support a combobox with an "other" field. In the full class, the values of the combobox and "other" textfield are bound to titleProxy and otherTitleProxy. In the "updateTitle" method, I examine these two values and set the person's title accordingly.

That's why I don't simply bind to #{person.title}.
