+## Multiple values arrays
+
+This breaks if there are multiple values for a single key. It works fine in the report plugin, but inline display shows the ARRAY reference, e.g.
+
+ IPv6:
+ - fd64:2c08:9fa7:4::1
+ - 2001:470:1d:4a6::1
+
+and:
+
+ {{$IPv6}}
+
+yields:
+
+ ARRAY(0x266db10)
+
+Seems to me this could be checked and `join(" ")`'d. :) -- [[anarcat]]
+
+> I wrote a stupid fix for this, which works for getfield, but isn't as good for report. It simply does that `join()`. Here's the patch:
