Re: [rules-users] peephole technique - cast to java.lang.Number problem
MVEL was my first suspect as well, but the same rules in java dialect (just
added setters/getters)
produced same exceptions.

To me this seems to be a bug, that occurs as soon as I set an event as
member of a fact (the LastEvent) - implementing the peephole technique.
At least I got it to do what I want...but not as niceley... as expected.

Re: [rules-users] peephole technique - cast to java.lang.Number problem
Maybe s.o. can contradict, but in 5.5.0 (and even before) it's MVEL
for dealing with constraint expressions anyway, behind the scenes.
