=head2 getRequiredProfileFields ( session )

Returns an array of hashes for required profile fields.  This array is ready
to be used as template variables in the WebGUI template system.

DEPRECATED - This method is deprecated, and should not be used in new code.  Use
the getRequiredFields method from WebGUI::ProfileField and specify the
translation to template variables directly instead.

NOTE: You should use the getRequiredFields method in WebGUI::ProfileField instead.

=head3 session

The current WebGUI session object.

=cut

# Builds Extra form requirements for anonymous registration.
sub getRequiredProfileFields {
	my $session = shift;
	my @array;
	foreach my $field (@{WebGUI::ProfileField->getRequiredFields($session)}) {
		push(@array, {
			'profile.formElement' => $field->formField,
			'profile.formElement.label' => $field->getLabel
			});
	}	
	return \@array;
}

#-------------------------------------------------------------------

=head2 isDuplicateEmail ( email )

Checks the value of the email address passed in to see if it is
duplicated in the system.  Returns true of false.  Will return false
if the email address passed in is same as the email address of the
current user.

DEPRECATED - This method is deprecated, and should not be used in new code.  Use
the isDuplicate method from WebGUI::ProfileField instead

=head3 email

email address to check for duplication

=cut

sub isDuplicateEmail {
    my $session     = shift;
    my $email       = shift;

    my $field = WebGUI::ProfileField->new($session,'email');
    return $field->isDuplicate($email);
}

#-------------------------------------------------------------------

=head2 saveProfileFields ( session, user, profile )

sub saveProfileFields {

}

#-------------------------------------------------------------------

=head2 validateProfileData ( session )

Validates profile data from the session form variables.  Returns processed data, warnings
and errors.

DEPRECATED - This method is deprecated, and should not be used in new code.  Use

There are two levels of validation:

=over 4

If the profile field is required, and the form field is blank, returns an error.

=item 2

If the profile field label is "email", then checks for a duplicate email and returns a
warning if it is a duplicate.

                          : WebGUI::ProfileField->getEditableFields($session);

    my $retHash   = $session->user->validateProfileDataFromForm($fields);

    my $format    = "<li>%s</li>";
    my $warningMessage  = "";
    my $errorMessage    = "";

    for my $warning ( @{ $retHash->{warnings} } ) {
