Movo to node

[jagr]

I've defined a process like this.

<?xml version="1.0" encoding="UTF-8"?>
<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="reserva">
 <swimlane name="reception">
 <assignment actor-id="pepeito"></assignment>
 </swimlane>
 <start-state name="Offer petition">
 <task name="Offer petition" swimlane="reception">
 <controller></controller>
 </task>
 <transition to="searchClient" name="search"></transition>
 </start-state>
 <task-node name="Create client">
 <task name="Create client" swimlane="reception">
 <controller></controller>
 </task>
 <event type="node-enter">
 <action class="com.aixtelecom.actions.CreateClientAction"></action>
 </event>
 <transition to="Create offer" name="crear oferta"></transition>
 </task-node>
 <task-node name="Create offer">
 <task name="Create offer" swimlane="reception">

 </task>
 <event type="node-enter">
 <action class="com.aixtelecom.actions.CreateOfferAction"></action>
 </event>
 <transition to="Createbooking" name="yes"></transition>
 <transition to="finish" name="no"></transition>
 </task-node>
 <task-node name="Createbooking">
 <task name="Createbooking" swimlane="reception">

 </task>
 <transition to="finish" name="Fi"></transition>
 </task-node>
 <node name="searchClient">
 <event type="node-enter">
 <action class="com.aixtelecom.actions.SearchClientAction"></action>
 </event>
 <transition to="Create offer" name="tr_create_offer"></transition>
 <transition to="Create client" name="tr_create_client"></transition>
 </node>
 <end-state name="finish"></end-state>
</process-definition>

At seachClient node i've created action handler on node-enter.
This action is:

public class SearchClientAction implements ActionHandler{

 /** The log. */
 private Logger log = Logger.getLogger(SearchClientAction.class);

 private static final long serialVersionUID = 3364679100134686576L;

 public void execute(ExecutionContext context) throws Exception {

 [connection with external mysql data base]

 if (result of query){
 //go to create offer
 node.leave(context, "tr_create_offer");
 }
 else{
 //go to create client
 node.leave(context, "tr_create_client");
 }
 }
}

I want depending on result of query, automatically process go to create client or create offer.
On create client node and create offer node i've configured actions with
System.out.println("Running on CreateClientAction...");
or
System.out.println("### Running on CreateOfferAction");

When i start the process and enter on searchClient node, always the process finish into create offer node.

17:06:49,000 INFO [STDOUT] Running on CreateClientAction...
17:06:49,000 WARN [ProxyWarnLog] Narrowing proxy to class org.jbpm.graph.node.TaskNode - thi
s operation breaks ==
17:06:49,000 INFO [STDOUT] ### Running on CreateOfferAction

Any idea?

[kukeltje]

what happens if the value of "result of query" is explicitly true? if that fails, please make a unittest that I can cut and paste (in one file) to try it out....

[jagr]

In this case

 if (true){
 //go to create offer
 node.leave(context, "tr_create_offer");
 }
 else{
 //go to create client
 node.leave(context, "tr_create_client");
 }

the result is

09:31:22,750 INFO [STDOUT] ### Running on CreateOfferAction
09:31:22,781 INFO [STDOUT] ### Running on CreateOfferAction

Seems that node changes how code is defined, but at last time always go to CreateOffer node.

[kukeltje]

so, maybe the response of your query is not (always) correct?

[jagr]

Yes. Query response it's correct.
In exemple, If I execute this ActionHandler

public class SearchClientAction implements ActionHandler{

 /** The log. */
 private Logger log = Logger.getLogger(SearchClientAction.class);

 private static final long serialVersionUID = 3364679100134686576L;

 public void execute(ExecutionContext context) throws Exception {

 [connection with external mysql data base]

 if (1==1){
 //go to create offer
 node.leave(context, "tr_create_offer");
 }
 else{
 //go to create client
 node.leave(context, "tr_create_client");
 }
 }
}

Result will be
INFO [STDOUT] ### Running on CreateOfferAction
INFO [STDOUT] ### Running on CreateOfferAction

If I execute this code

public class SearchClientAction implements ActionHandler{

 /** The log. */
 private Logger log = Logger.getLogger(SearchClientAction.class);

 private static final long serialVersionUID = 3364679100134686576L;

 public void execute(ExecutionContext context) throws Exception {

 [connection with external mysql data base]

 if (1==2){
 //go to create offer
 node.leave(context, "tr_create_offer");
 }
 else{
 //go to create client
 node.leave(context, "tr_create_client");
 }
 }
}

Result will be
INFO [STDOUT] Running on CreateClientAction...
INFO [STDOUT] ### Running on CreateOfferAction

[kukeltje]

sorry, then you are on your own... if it works with static true/false, but not with your query, we can't help you

[jagr]

I think that i haven't explained very well.

In all actions, (static true/false, query result, equals between int, string...) when code execute

node.leave(context, "name of transaction");

always, the process enter into 2 nodes. Into node that execute code, and other node.
In exemple.
If I execute node.leave(context, "tr_create_client"); without if, always proces go to node :
first: create client node
second: create offer node.

[kukeltje]

sorry, but to me this does not make it much more clear... make a real unit test with embedded processdefinition (as string) and inner class for action.... then we can have a look

[jagr]

Sorry kukeltje.
Can you say some link that explain how to make unit test? I've never made it.
Thanks!!

[kukeltje]

http://www.junit.org/

and look at (almost) *all* the testcases in the jbpm source for real jbpm related examples
