How to access a label inside the tab of a notebook

Hello everyone,

  I'm trying to access a label located inside a GroupBox inside the
first tab of a Tabbed Notebook in order to modify its text. I can't
address the label successfully.

  I have a button inside the same first tab (but not inside the
GroupBox) and when I press on it the subroutine to change the label is
called. It gives the error message:

change Label !
Unknown widget or method "Prima::TabbedNotebook::Tab1" at ./tN-1.pl
line 21

The code is:

use Prima qw(Application Notebooks);
use Prima::VB::VBLoader;

my $form = Prima::VBLoad('./tN-1.fm',
      'RButton' =>
      {
       onClick => \&changeLabel
      },
);

$form->execute;

sub changeLabel
{
  print "change Label !\n";
  $form->TabbedNotebook1->Tab1->GroupBox1->ALabel->text("Label is
changed"); }

Please note that in this incarnation I tried adding 'Tab1' (which is
the name of the first tab). Otherwise the following gives the same
error:

$form->TabbedNotebook1->GroupBox1->ALabel->text("Label is changed");

The label is indeed named ALabel.

Any help is very much appreciated,

Al
