Thank you Michael. I will try this.

Hi,
You will need to implement and register a custom property editor for
you Directeur class which Spring will use to convert the class to and
from String form. To do this:
1) Create a class (I often do this as a nested class on the
controller) that extends PropertyEditorSupport. You will need to
override the setAsText() and getAsText() methods. Please be sure to
include null value handling here.
2) Register your new class on your controller using the initBinder()
method.
If you need more detail do a search for PropertyEditorSupport on the
user list in Nabble - something should pop up!

Hi,
I want to add a drop down list of user in a page (Spring MVC) :
so I implement the referenceData of my FormController :
@Override
@SuppressWarnings("unchecked")
protected Map referenceData(HttpServletRequest request) throws
Exception {
log.debug("entering 'refenceData' function ..." );
// return super.referenceData(request);
Map model = new HashMap();
List<User> directeurs = getUserManager().getUsers(new User());
model.put( "directeurs", directeurs );
return model;
}
in my jsp :
<form:select path="directeur" itemValue="id" itemLabel="lastName"
items="${directeurs}" ></form:select>
the data appears correctly on my page but when I save my form I've
got
an error ( a other one;-) ) :
-----------------------
Failed to convert property value of type [java.lang.String] to
required
type [org.appfuse.model.User] for property directeur; nested exception
is java.lang.IllegalArgumentException : Cannot convert value of type
[java.lang.String] to required type [org.appfuse.model.User] for
property directeur: no matching editors or conversion strategy found
-----------------------
I don't know how to correct the problem ( where and how do I make the
conversion ).
I have 2 small other questions :
- Is it possible to show in the list a label like surname + lastname ?
Yes - just implement a method on your class that returns the label in
the correct format and set the itemLabel attribute accordingly.
- I have seen a <s:select tag in my generated controller which
come from
Struts (I think). Is there a reason . better than Spring select tag ?
Not sure on this one. The Spring tag is likely to work better with a
Spring controller due to binding paths.
