The action node allows you to simply execute a piece of code.  While Drools 
4.0.7 only allows you to use mvel fragments, the upcoming Drools 5.x release 
also allows you to use the Java dialect.  It will also allow you to access 
globals or workingMemory etc.

An action node currently does not have direct access to information about 
the previous node that triggered the action.  Could you clarify why you 
would need this?  In Drools5, sharing of information between nodes using 
globals or the working memory will be possible.  But if you could provide a 
good use case on why you would need access to this information, I could see 
whether it would be possible to expose this kind of information in the 
action code as well.
