=head1 NAME
Package WebGUI::AssetHelper::Cut
=head1 DESCRIPTION
Cuts an Asset to the Clipboard.
=head1 METHODS
These methods are available from this class:
=cut
#-------------------------------------------------------------------
=head2 process ()
Cuts the asset to the clipboard. If the user cannot edit the asset, or the asset is a
system asset, it returns an error message.
=cut

my ($self) = @_;
my $asset = $self->asset;
my $session = $self->session;
my $i18n = WebGUI::International->new($session, 'WebGUI');
if (! $asset->canEdit) {
return { error => $i18n->get('38'), };
}
elsif ( $asset->get('isSystem') ) {
return { error => $i18n->get('41'), };
}
# Fork the cut. Forking makes sure it won't get interrupted
my $fork = WebGUI::Fork->start(
$session, blessed( $self ), 'cut', { assetId => $asset->getId },
);
return {
forkId => $fork->getId,

}
#----------------------------------------------------------------------------
=head2 cut ( process, args )
Handle the actual cutting in the forked process.
After this routine returns, C<Forks> marks this task as finished.
