Thought of this possibility too.
That's why I added to the bean constructor the newt line:
Person loginPerson = new Person("",""); // Dummy init for
loginName
& password
This ensured that not only Person was != null, but also the 2 fields
used of Person, on the page. (made a construtor just for this purpose)
This had no effect however.

Can you check that your getLoginPerson method returns always != null?

Subject: Re: Variable Resolver
Yes I did...
I'll reconstruct the code, for the moment I have bypassed the prob
by having LoginBean extend Person. :-(
Originally loginPerson(the field itself) itself was private, made it
public just in case, but that didn't change anything.
I have also googled for this (perhaps with the wrong terms, like
"JSF and recursive variable resolving") but that didn't came up
with much. :-)
What I don't know is whether the Variabe Resolver was specified to
also resolve in that fashion in the first place.
What I also tried was to make the model.Person class a (managed)
bean to see whether that would make a diff, but it didn't.

Hi Philippe,
did you have public getter and setter for Person in loginBean?
the expression #{loginbean.loginPerson.lastName} is resoved to
"loginbean.getLoginPerson().getLastName()"
where loginBean is the object from session scope.
otherwise please post the stacktrace and more of your relevant code.
Regards,
Volker

Hi,
I have a Variable Resolver question.
To set the scene first:
Trying to follow good practice, I build up my model classes in
"XXX.model.modelClass". e.g. "XXX.model.Person"
For the front end, there's a package "XXX.web.beans" e.g.
"XXX.web.beans.LoginBean"
& In that LoginBean I had a field declared:
"Person loginPerson;"
--> In the JSF page I obviously tried:
Login: #{loginbean.loginPerson.lastName} (I declared "loginbean"
properly in the faces-config, session scope)
Yet this continues to give me errors. (of type conversion/validation
"while updating model")
Which made me wonder whether the Variable Resolver was made for this
sort of schemas after all?
If not that would be a pitty I think.
I made it work by having LoginBean extend Person but qua design I
think
this is much less elegant.
(but still way better than copy all fields again in front-end
classes -
why make a model then?!)
