Hi David,
Thanks for your prompt reply.
I am trying similar to your first suggestion. In your case, I
suppose, firstChoice has to be type String, but I made firstChoice as
type Course, where Course has several properties and one of them is
title. So I am trying to do similary to:
<h:selectOne id="firstChoice" value ="#{applicant.firstChoice.title}">
<f:selectItems value="#{school.availableCourses}"/>
</h:selectOne>
Basically, trying to bind value to #{applicant.firstChoice.title}
instead. Is it possible?
Thanks,
Damar

Hi,
Am a little confused by your explaination. I bet you are transforming a
textfield String (the course title) somehow in a Course object later.
I have 2 suggestions:
The first it to replace you textfield with a combo box, like this
<h:selectOne id="firstChoice" value ="#{applicant.firstChoice}">
<f:selectItems value="#{school.availableCourses}"/>
</h:selectOne>
with your school bean having something like this
public SelectItems[] getAvailableCourses(){
...
}
The second way to go is to use a converter
<h:inputText id="firstChoice" value ="#{applicant.firstChoice}">
<f:converter converterId="my.custom.Converter"/>
</h:inputText>
with the converter define in you faces-config.xml:
<converter>
<converter-id>my.custom.Converter</converter-id>
<converter-class>path.to.my.custom.CourseConverter</converter-class>
</converter>
your converter being an implementation of
javax.faces.convert.Converter
