in reply to WWW::Mechanize::Firefox could not click submit button

Sorry for format. On IBM site I am trying to automate login and then do some patch download. 

#!/usr/bin/perl -w

use strict;

use WWW::Mechanize::Firefox;

my $mech = WWW::Mechanize::Firefox->new(
    autoclose => 0,
    autodie => 1,
);

$mech->get('https://www-304.ibm.com/pkmslogin.form');

sleep 7;

my $dumy;
#found that with only username and password parameters in #set_visible
+ function it entered only password in username #field so added this d
+ummy variable.

my $username = 'user';

my $password = 'password';

$mech->set_visible( $dumy, $username, $password );

my $retries = 10;
while ($retries-- and ! $mech->is_visible( xpath => '//*[@id="submit"]
+' )) {
      sleep 1;
};
die "Timeout" unless $retries;

    I can't replicate the problem with WWW::Mechanize::Firefox 0.66. Maybe you are on an older version?

    To see what XPath expression is generated and passed on to Firefox, you can turn up the log level:

    my $mech = WWW::Mechanize::Firefox->new(
    autoclose => 0,
    autodie => 1,
    log => ['debug'],
);

    That will produce lots and lots of output, and somewhere in there you might find the error message, and somewhere before that the invalid XPath expression that causes it. But before doing so, consider upgrading to the latest versions.

    Well, this really has nothing with perl :)

    How did you come up with that xpath expression?

      Thanks for reply. Above mentioned problem is solved. I used below statement for click. 

      $mech->click({ xpath => '//*[@value="Submit"]' });
