Description
Executable model rule compilation fails when trying to build a pattern using constraint grouping.
Example of DRL that fails to compile:
rule "TestBusiness"
when $p : Pojo(departuretimedayofweek (== 1 || == 2 || == 7) )
then
end

The example works fine when compiling without executable model.
