=head2 www_activityHelper ( session )
Calls an activity helper. In the URL you must pass the activity class name, the subroutine to call and any other
parameters you wish the activity helper to use. Here's an example:
/page?op=activityHelper;class=MyActivity;sub=doTheBigThing;param1=makeItGo
=cut
sub www_activityHelper {
my $session = shift;
my $form = $session->form;
my $class = "WebGUI::Workflow::Activity::".$form->get("class");
my $sub = $form->get("sub");
return "ERROR" unless (defined $sub && defined $class);
my $load = "use ".$class;
eval($load);
if ($@) {
$session->errorHandler->error("Couldn't load activity helper class $class because $@");
return "ERROR";
}
my $output = "";
my $command = $class.'::www_'.$sub;
no strict;
my $output = eval { &$command($session) };
use strict;
if ($@) {
$session->errorHandler->error("Couldn't execute activity helper subroutine $sub because $@");
return "ERROR";
}
return $output;
}
