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:
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:
<input type="hidden" name="_flowExecutionKey" value="<c:out value='${flowExecutionKey}'>"/>
and it dont work too
OperationsCommand:

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

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
