Getters/setters are only required for JavaBean conformity, e.g. to use prop.
I've just tested this on 5.0.5 (maybe 5.0.6 later if I get time) ...
There is a bug - setting the property to null doesn't work.
If someone can verify this on 5.0.6 before I do, please log a JIRA.
Cheers,
Nick.

Hmm... looking at javassist, it looks like there is the ability to modify
field level access within a method. Perhaps, if changing to the setter
worked then this should be filed as a defect, if it isn't already.

Hi,
You are correct. this does bring up a question:
if I have an attribute, I should use a setter to assign it? like this:
private String id;
void onActivate() {
id = "myid"; // wrong
setId("myid"); // correct ?
if (id == "myid"); // wrong
if (getId() == "myid"); // correct?
}
?

I would guess that the right way to do it would be to use the setter
method
for the attribute. I haven't looked, but I would guess that Tapestry is
catching assignments to that attribute via the setter, and when you set
it
directly you are bypassing that code.

Hi,
I have this class:
public class Confirmation {
@Persist
private String uid;
public Class onActivate(String id) {
if (uid == null) {
uid = id;
}
return null;
}
public String onPassivate() { return uid;}
String onActionFromAutoLogin() {
uid = null;
return "MyPage";
}
}
even i set uid to null, it is still not null next time when the page is
activated, why? what's the correct way of setting a persisted variable
null?
Thanks.
