Hello Regis,
it seems that the entity has already been consumed. You may have already
get the content of the entity (maybe a call like entity.write(...)).
If you don't see what happen, you may send us your code.
best regards,

Sorry i mix to many functions :) I read a second time the javadoc and
i discover you can't use both handlePut() == lowerlevel
and put() == high level.
So i have another issue if something can give me a clue:
When i try to get my data form from the handlePut() or the
handlePost() with this code it works very well !:
@Override
public void handlePut() {
System.out.println(" handlePut()");
Form form = getRequest().getEntityAsForm();
String formId = form.getFirstValue("formId");
System.out.println("=> formId = " + formId);
super.handlePut();
}
@Override
public void handlePost() {
System.out.println(" handlePost()");
Form form = getRequest().getEntityAsForm();
String formId = form.getFirstValue("formId");
System.out.println("=> formId = " + formId);
super.handlePut();
}
But now when i try to use the default implementation with put() and
post() method with this code it fails ! :
I get this from this post
http://article.gmane.org/gmane.comp.java.restlet/2420/match=form+post
(i check the sample this is how it should work)
@Override
public void post(Representation entity) {
System.out.println(" post()");
if (entity != null) {
Form form = new Form(entity); //throws error
String id = form.getFirstValue("formId");
System.out.println("=> formId = " + id);
}
}
@Override
public void put(Representation entity) {
System.out.println (" put()");
if (entity != null) {
Form form = new Form(entity); //throws error
String id = form.getFirstValue("formId");
System.out.println("=> formId = " + id);
}
}

Somebody can explain in which case to use the handlePut() and the
put(Representation entity) ?
Thanks a lot for the reply

Thanks a lot for the quick reply now it works very well.
It was not clear.
I hope it will help.
But know i have a second problem , when i try to access to my data
in the request object in a handlePut() or in handlePost() like this
Form form = getRequest().getEntityAsForm();
String value = form.getFirstValue("text");
String method = form.getFirstValue ("method");
if i doing getRequest().getEntityAsObject() it returns a null ....
I get this error, what does it mean ?

Hi Regis,
There is a built-in service for that, based on a query
parameter. See:
http://www.restlet.org/documentation/1.0/faq#19
You have to put the parameter into the query string of the
action's URI.
<form action="api/form?method=put" method="post"
enctype="text/plain">
Best regards,
Jerome
