Rasj does not support return complex number from WCPS

[Bang Pham Huu]

When WCPS 1.5 translates this WCPS query

for c in (mr) return (2,3)

to Rasql

SELECT complex(2, 3) FROM mr AS c

when Petascope execute this query, it throws exception

Caused by: rasj.RasTypeNotSupportedException: Exception: Base type typeName: 
 typeID:  0
  as RasCollectionType is not supported yet.

	at rasj.odmg.RasOQLQuery.execute(RasOQLQuery.java:254)
	at petascope.util.ras.RasUtil.executeRasqlQuery(RasUtil.java:151)

However, this Rasql query can be executed normally in Rasql

rasql -q 'SELECT complex(2, 3) FROM mr AS c' --out string
rasql: rasdaman query tool v1.0, rasdaman v9.2.0-beta1-gf79e291 -- generated on 21.01.2016 14:39:26.

It works if encode complex number inside "encode( )" operator, here is example:

http://localhost:8088/rasdaman/ows?service=WCS&version=2.0.1&request=ProcessCoverages&query=
for c in (mr) return encode(coverage complexNumber 
over $x x (0:1),$y y (0:1) values 
condense over $x x (0:1),$y y (0:1) 
using (0.1, 0.1),"csv")&wcpsVersion=2.0

which returns Rasql

SELECT encode(
MARRAY x in [0:1,209:210] VALUES 
CONDENSE + 
OVER x in [0:1,209:210] 
USING complex(0.1, 0.1), "csv" ) 
FROM mr AS c

and result

{(0.4, 0.4),(0.4, 0.4)},{(0.4, 0.4),(0.4, 0.4)}
