Hi Sven,

Thanks a Lot for you help...
One last question.. For me only works if the ActionButton was part of the 
Form. Is really necessary or I did some mistake ??

Hi Andre,

when you click the button a POST request is sendet to the server.
The id is not part of the POST-requests url, all parameter of the
GET-request are removed in the forms action attribute.

You could add a HiddenField to your Form, in onGet() you populate the
HiddenField with the ID, in onButtonClick you read the id from your
HiddenField.

Hi Stephan, thanks for your reply

You are correct about redirecting from a page with a table to the page 
with the button...
I did what you send me and in onInit() method I got the id value with no 
problem...

But how can I get this value in the onButtonClick method ???
for example, the result of 
System.out.println(getContext().getRequest().getParameter("id")); in 
onButtonClick method is null
I think all I want is keep the parameter id when I click the Action Button

Thanks for your help
Regards.

Hi Andre

If I understand correctly you are redirecting from a page with a table to 
the page with the button?
Have you tried reading the id from the request in your onInit() method in 
EditRoteadorSnmp?
E.g.
@Override
public void onInit() {
super.onInit();
           id = getContext().getRequest().getParameter("id");
     }

Regards
Stephan

Betreff: Doubt in using ActionButton

Hi,

Using the Click Examples, I'm trying to put a ActionButton in a Edit Page
but I cannot make work.. Here my doubt

After the user choose the correct row in the table, the user is redirect 
to
the EditRoteadorSNMP Page

http://192.168.80.110:8080/NetworkAdvisor/edit/edit-roteador-snmp.htm?id=200&referrer=%2Ftable%2Froteador-table.htm

You can see the id is equal 200

The form in this page works nice and permit the user edit the row with id 
=
200

I add in this same page, one ActionButton, not inside the Form...

My doubt is why I cannot get the id value after the user click this Action
Button

Here the code

public class EditRoteadorSnmp extends BorderPage {

  private Form form = new Form("form");
  protected ActionButton button = new ActionButton("action");
 @Bindable protected Integer id;
.....

public EditRoteadorSnmp() {

       addControl(form);
       addControl(button);
       button.setListener(this, "onButtonClick");
........

public boolean onButtonClick() {

       System.out.println(id);                ---- why I receive the NULL
value here ------------------
}

Thanks in Advanced

My Best Regards
