jBPM decision nodes are very useful to create some alternative path along the workflow. The implementation of this node will choose the correct way.
To program these kind of nodes I prefer to develop a DecisionHandler rather than using an expression.
public class Validacion implements DecisionHandler{....}
Implement a decide method is mandatory:
public String decide(ExecutionContext executionContext) throws Exception;
Among this function code lines you can query database, consult session or recover variables from execution context:
executionContext.getVariable("previouslySetVariable");
This function must return a String containing the name of the transition to choose.
As the other nodes, you must configure the handler class with the node using Eclipse interface.
