[Spring Web Flow 2.0] The requestPathInfo is null

bonjour

Celà fait quelques jours que j'essaie de faire tourner cette petite appli pour tester SWF

J'utilise Eclipse 3.3 Europa, Tomcat 5.5 , JSTL 1.2, Spring 2.0 et Web Flow 2.0

J'ai cette exception:

Code:

java.lang.IllegalArgumentException: The requestPathInfo is null: unable to extract flow definition id or flow execution key

if I understood correctly, with WebFlow 2.0, no more need to have the hidden input for the flowExecutionKey
but anyway, I tried also with this:

Code:

<input type="hidden" name="_flowExecutionKey" value="<c:out value='${flowExecutionKey}'>"/>

and it dont work too

OperationsCommand:

public class OperationsCommand {
 
	private String choiceOperations;
 
 
	public String getChoiceOperations() {
		return choiceOperations;
	}
 
	public void setChoiceOperations(String choiceOperations) {
		this.choiceOperations = choiceOperations;
	}
 
 
}

public class OperationsCommandValidator implements Validator {
 
	 public void validate(Object obj, Errors errors) {
 
		 ValidationUtils.rejectIfEmpty(errors, "choiceOperations", "required","required.");
 
	 }
 
	public boolean supports(Class clazz) {
 
		 return clazz.equals(OperationsCommand.class);
	}
 
 
 
}

merci d'avance
