I give up. 2 days of solid research and i can't find a single example of how to get this to work 
use Tk;
use Tk::MatchEntry;

@dataa = [ qw/Abberley Abberton Abbotsley Accrington/];
@datab = [ qw/Babraham Bacton Bexhill Bradfield/];


 my $mw = MainWindow->new(-title => "i wish this would work",);
 $mw->geometry("200x70+0+0");
 
        my  $label = $mw->label("type somthing in the box");

        my    $me = $mw->MatchEntry(
    -variable       => \$place,
        -choices        => @dataa,
        -autosort       => 0,
        -fixedwidth     => 0,
        -ignorecase     => 1,
        -maxheight      => 10,
        -listwidth      => 240,
        -entercmd       => sub {#do some stuff
                                },
        -onecmd         => sub {#do some stuff then
                           $me->configure('choices' => @datab);
                },
            )->pack(-side => 'left');
 Tk::MainLoop();

what i hoped would happen is that the choices in array @dataa would be used to fill the listbox contents and once the first caharcter was entered the contents would be altered to array @datab but i just get error "XS_Tk__Callback_Call error:Can't call method "configure" on an undefined value at line 22". any help will go along way to restoring my sanity Thank you for your time in reading this far -Daniel
