Thanks, it turns out my email post was correct and my code i was testing with
with different..

If I do,

� � �$a : MyBean(name=="one");
� � �not( MyBean(name=="two", this after [0s,10s] $a))

which means, �item not received between 0 and 10 seconds
then it works as expected..

If I do
� � � � $a : MyBean(name=="one");
� � � � not( MyBean(name=="two", this after [10s] $a))
which means, item not received between 10 and infinity seconds
then I get the false rule trigger when name==other inserted

Need to get my head around that one.
