In the view template:
{{if $event->rsvp || $address || $event->map( 270, 270 ) }}
<div class='ipsColumns ipsColumns_collapsePhone'>
<aside class='ipsColumn ipsColumn_wide'>
<div>
{template="eventSidebar" group="view" params="$event, $attendees, 'Mob', $address"}
</div>
</aside>
<div class='ipsColumn ipsColumn_fluid'>
{{endif}}
Happens that the same conditions are also checked in the eventSidebar template:
{{if $address || $event->map( 250, 150 )}}
and
{{if $event->rsvp }}
So it won't have any issue if you remove the condition from the view template. Leaving it as the way it is today, it prevents to add something in the eventSidebar, unless the event has an address/map or is RSVPed, which can't be required/necessary in all events.
Thank you.
