perch_events_event_categories() Not Working

Adding <?php perch_events_event_categories() ?> to my page is causing the following error:

Warning: Missing argument 1 for perch_events_event_categories(), called in /var/www/public/dpn.dev/events.php on line 18 and defined in /var/www/public/dpn.dev/dpn-admin/addons/apps/perch_events/runtime.php on line 124

Notice: Undefined variable: id_or_slug in /var/www/public/dpn.dev/dpn-admin/addons/apps/perch_events/runtime.php on line 126

The events are displaying correctly with perch_events_custom(). I haven't changed any event templates except for the one I'm using to display events. Diagnostics:

If anyone else has this probllem, got this working by using:

  'template' => 'categories.html'

And in categories.html:

<li><a href="/events?cat=<perch:events id="categorySlug" />"><perch:events id="categoryTitle" /></a></li>

Also, any time I make changes to the category template, I also need to delete a file in /perch/resources that looks something like perch_blog.perch_events_categoriesaadd28983c5ee345bd71848b29dad9ff.cache, otherwise the changes don't show.

...aaand just leaving this here in case someone else needs it. If you're having problems with category caching, you can use 'cache' => false:

<?php perch_events_categories(array(
  'template' => 'categories.html',
  'cache' => false
)); ?>

As the name suggests, perch_events_event_categories() needs an event to return the categories for. The first argument should be an event identifier.

I must admit, I wasn't paying attention to function names as much as furiously searching the forum and docs for anything that resembled what I was after. :)

Funny how that might lead to problems! ;)
