4:30 p.m.
In 5.1 this was valid syntax:
rule "OrderActiveInLast7Days"
when
$order : DrugOrder((start != null && start before $now),
(stop == null || stop after[-7d,*] $now))
then
#stuff
end
In 5.2.0.CR1 it complains about the asterisk. Is that no longer
supported?
The error I get is "no viable alternative at input '(' in rule
"OrderActiveInLast7Days"". If I remove the part of the constraint in
brackets "[-7d,*]" then it compiles.
Thank You,

Wouldn't you just use the single parameter form?
$order : DrugOrder((start != null && start before $now), (stop == null ||
stop after[-7d] $now))
I'm not the CEP expert though - I know we don't support "*" in
Guvnor's
guided editors though.

This is indeed a regression, due to the switch to "free form expressions"
and the resulting changes in the parser. Originally (5.1.) there were the
forms "*" (or "+*") and "-*" for positive and negative
infinity,
respectively. (The converter in TimeUtils still handles these strings; it's
DRLParser.g that needs to be fixed.) Omitting the 2nd operand in temporal
operators as a workaround isn't possible where "-*" is intended as 1st
operand.
