Update:
the sample project may have the modifier "final" on the main method for
some reason...I have no idea how or why that got on there, but will
prevent eclipse from running it.
Also, I believe i found the problem:
rule "Wait for follup config"
lock-on-active
when
$dr: DataReading(reading > 10.0) from entry-point "My Stream"
not($de: ConfigEvent(this after[0s,10s] $dr))
then
System.err.println("Action");
end
Should read:
rule "Wait for follup config"
lock-on-active
when
$dr: DataReading(reading > 10.0) from entry-point "My Stream"
not(ConfigEvent(this after[0s,10s] $dr) from entry-point "My Stream")
then
System.err.println("Action");
end
where the temporal matching predicate must also state the stream I was
injecting events to. This seems to work ok, but I would still
appreciate feedback.
Thanks,
Chris
