Flowprogrammer flowConfig.actions does not always return as array / list

{"installInHw":"true","name":"test","node":

{"@id":"00:00:00:00:00:00:00:02","@type":"OF"}

,"ingressPort":"2","priority":"500","etherType":"0x800","actions":"OUTPUT=2"}

{"installInHw":"true","name":"test22","node":

{"@id":"00:00:00:00:00:00:00:02","@type":"OF"}

,"ingressPort":"1","priority":"500","etherType":"0x800","actions":["OUTPUT=1,2,3","DROP"]}

Docs however state the type should be array / list.
