[rules-users] Does drools have any trigger?

[Edson Tirelli]

   Lindy,

   I am not aware of this "when changed" feature in BA, but by your
description, Drools does not have the same thing out of the box. You would
have to explicitly control this on your rules.

   Interesting feature nevertheless. With the implementation of true modify
that we will be doing for the next iteration, it should be quite easy to add
such a feature.
