Adding an Action link to Ticket/Display.html/BeforeActionList

When/Where are the actions added to @Actions?

1) for some reason the \@Actions ArrayRef is empty when I access it in 
the callback. Where do the Actions come from? I am talking about the 
links "Reply", "Comment", "Forward", "Stall", ...

2) If I push a simple string to \@Actions they end up in a yellow 
"Results" Widget. see attached screenshot


#local/plugins/RT-Extension-OneClickClose/html/Callbacks/RT-Extension-OneClickClose/Ticket/Display.html/BeforeActionList
<%init>
use Data::Dumper;
$RT::Logger->debug("\n\n###\n".Dumper($Actions)."\n\n###\n");
push @$Actions, "foo";
</%init>

<%args>
$Actions     => undef
$TicketObj   => undef
</%args>


Output:
###
$VAR1 = [];
