WPCS1.5 - Error when compare binary coverage expression with scalar value in boolean result

[Bang Pham Huu]

in WCPS 1.0 and WCPS 1.5 this query

for c in (mr) return encode(c[i:"CRS:1"(0), j:"CRS:1"(50)] 
+ c[i:"CRS:1"(0), j:"CRS:1"(50)] = 146,
 "csv")

will return true {t} as c[i(0), j(50)] = 73.

However, it does not work if change the second operand from coverage to scalar value (73) as below:

 for c in (mr) return encode(c[i:"CRS:1"(0), j:"CRS:1"(50)] + 73 = 146, "csv")

with WCPS 1.0, it will returns {73} which is not correct.

And WCPS 1.5 it will return exception

java.lang.ClassCastException : petascope.wcps2.translator.BooleanNumericalComparissonScalar 
cannot be cast to petascope.wcps2.translator.CoverageExpression
