General JSF question -- Class object!

[Damar Thapa]

Hi,

I have following classes:

Class Course(
        String title,
        String startDate.
        …..
        ….

}

and

Class Apply{

String studnetName;
Course firstChoice;
.....
…….
…..
}

In the apply form (page), I havae a field to accept course title from
the applicant  ie <h:inputText id="firstChoice"
value="#{applicant.firstChoice.title}"/>. Since title is unique, I can
retrieve Course object for firstChoice properties later before saving
Apply object. But, I am getting ""firstChoice": Error during model
data update." error on "#{applicant.firstChoice.title} . Can somebody
on the list point me what am I missing?

Any pointers would be highly appreciated.

Thanks,

Damar
