Petascope can't handle curly brackets in an extendExpr query

[Dirk Daems]

The following abstract WCPS query fails. It is a valid query according to the WCPS specification. This coverage has an associated null value: in the ps_nullset table there is a record for this coverage (nullvalue = 0). Apparently, Petascope can't handle the curly brackets in the following WCPS query:

for msa in (mean_summer_airtemp)
return encode(
   extend(msa,
          {x : "http://www.opengis.net/def/crs/EPSG/0/4326" (110:160),
           y : "http://www.opengis.net/def/crs/EPSG/0/4326" (-45:8)}
          ),
"png")

Error message in log file:
