Re: [rules-users] getting details of facts triggering rules
This may be more conveniently done from an event listener but
drools.getActivation() should give you the Activation. Then you get
the Collection<FactHandle>.
For each of them,
org.drools.runtime.KnowledgeRuntime.getObject(
org.drools.runtime.rule.FactHandle )
gives you the fact objects that participates.
You can also access bindings:
List<String> declIds = activation.getDeclarationIDs();
Object declVal = activation.getDeclarationValue( declId );
Be careful, things may have passed away, i.e., you can get nulls.

Hi,
I've tried to figure this out but haven't been able to.
How can I, from the RHS, figure out the details of what triggered a rule.
I can access the facts individually by name, but how do I do it in a
generic fashion that would work in the RHS of any rule?
I am using decisiontables and want to be able to have a function that is
something like printTriggeringDetails()
I came across drools.getTuple but am not sure if that's the correct path
to go on. From there I get InternalFactHandles but don't know how to turn
those into human-readable facts.
Thanks for any help,
Archie
