+        "Why is there a form.media call???"
+        We use modal forms, right?
+        And we use dal (django-autocomplete-light), right?
+        In order to get these nice autocomplete (js triggered) form fields to work, we need to load form.media
+        somewhere. BUT when these fields are called inside a modal form (which we use quiet often), the form.media
+        can not be called properly due to some deprecated functions of jquery regarding synchronous calling.
+        So, we simply call the form.media in here, in case there is any form.media to be loaded.

+    {{ form.media }}
