This works in DRL:
Assignment(
(PatternEntryPropertyWildcard.ANY == $shiftTypeWildcard)
|| (shiftType == $shiftType)
...
)
But this doesn't work in DRL:
Assignment(
(null == $shiftType)
|| (shiftType == $shiftType)
...
)
It says "no viable alternative at input 'null' in rule"
Is there a specific reason why enum literals work on that spot and the
null literal doesn't?
Here's the full stacktrace:
Exception in thread "main" java.lang.IllegalStateException: There are
errors in the scoreDrl's:[536,8]: [ERR 101] Line 536:8 no viable
alternative at input ')' in rule "unwantedPatternShiftType2DaysPattern"

Just guessing, but is PatternEntryPropertyWildcard defined inside
Assignment?
When you write
Assignment(null == $shiftType)
You are writing a Field Constraint over Assignment. So, the first element of
the constraint should be a field from Assignment, but you are putting
"null". I think that's your error there.

PatternEntryPropertyWildcard is not defined inside Assignement (not as a
property, not as a subclass).
PatternEntryPropertyWildcard is a class (an enum actually), which is
imported.
