[rules-users] Compiles in 4.07 not in 5.0 Snapshot (3/20)

[Wolfgang Laun]

The RHS of a rule X winds up in some class Rule_X_0. Calls like insert(),
retract(), etc. are, by definition, method calls of WorlingMemoryEntryPoint,
and the compiler ought to prefix them with the global reference to that
object, i.e., "drools". This fails within if statements, both branches.

If you write, inside (or outside) if
   drools.insert(...);
   drools.retract(...)
all is well.
