[rules-users] Drools Flow - Replay

[Swindells, Thomas]

Either have a very wide and shallow flow structure where you set a variable indicating the next node to be displayed, you then use a split and join nodes to loop round this structure.

It's the equivalent of the following pseudo code:

1. displayNode = "first"
2. switch(displayNode)
3. case first:
     Get answers
    displayNode = "second";
break
4. case second:
     Get answers
    displayNode = "third";
    break
5: case third:
     Get answers
    displayNode = "done";
break
6: case done:
        Goto 10
    Break
7: goto 2
10: finished.

Obviously if the users doesn't fill in the answers but instead picks a different point display node would be updated separately.

You can also do a similar effect with just plain rules where you have an object which determines the next rule to fire.
