Hi,
The problem is happening when I initalize manually the state of my machine,
and I trigger the event.
do you think that initializing the state manullay is causing the problem ?
public class NEventDispatcher implements EventDispatcher {
public NEventDispatcher() {
}
@Override
public void cancel(String arg0) {
}
@SuppressWarnings("unused")
@Override
public void send(String sendId, String targe, String type, String event,
Map params, Object hints, long delay, List externalNodes) {
if (externalNodes == null || externalNodes.size() <= 0)
return;
// some stupid code here, i'm just inserting the information in my
database
}
}
The implementation of the machine that i use :
tracer = new NTracer();
nEventDispatcher=new NEventDispatcher();
exec = new SCXMLExecutor(new JexlEvaluator(), nEventDispatcher,
tracer);
exec.setStateMachine(config);
exec.addListener(config, tracer);
map=new HashMap();
jExlCtx = new JexlContext(map);
exec.setRootContext(jExlCtx);
exec.setErrorReporter(tracer);
and how i'm initializing the state :
@SuppressWarnings("unchecked")
public void setInitialState(String idOfPersistedState)throws Exception {
if (idOfPersistedState != null) {
Map<String, State> allStates =
exec.getStateMachine().getTargets();
State state = allStates.get(idOfPersistedState);
if (state == null) {
throw new Exception("Unknown state "
+ idOfPersistedState);
}
// got the state, now set it
@SuppressWarnings("rawtypes")
Set states = exec.getCurrentStatus().getStates();
states.clear();
states.add(state);
}
}
