Thanks Edson,

Will try that out. One more question, when my pattern matches against
the event, am I to assume the pattern matching in the order the events
were placed or do I have to define additional matching statements on the
pattern (i.e. comparing against a timestamp) to ensure I am matching
against the most recent event?
