Knowing which token you are in?

[fernando.deleon]

Ok...am starting to evaluate JBPM and doing some small proof of concepts.
hooked JBPM with Spring + JSF running on Tomcat using an Oracle DB

My simple question is this..
I start a process instance and all is fine.

<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="myholidaydefenition">

 <start-state>
 <transition to="reqHoliday" name="requestHoliday"/>
 </start-state>

 <task-node name="reqHoliday">
 <task name="requestHolidayTask"/>
 <transition to="evaluateLeave" name="evaluateRequest"/>
 </task-node>

 <decision name="evaluateLeave">
 <handler class="au.com.qtc.simpleForms.jbpm.decision.EvaluateLeaveDecisionHandler"/>
 <transition to="end" name="yes">
 <action class="au.com.qtc.simpleForms.jbpm.action.NotifyAboutLeaveActionHandler"/>
 </transition>
 <transition to="giveDonuts" name="no"/>
 </decision>

 <!--<task-node name="evaluateLeave">
 <task name="evaluateLeaveTask"/>
 <transition to="end" name="giveLeave">
 <action class="au.com.qtc.simpleForms.jbpm.action.NotifyAboutLeaveActionHandler"/>
 </transition>
 <transition to="giveDonuts" name="noLeaveSorry"/>
 </task-node> -->

 <task-node name="giveDonuts">
 <task name="donutConsolation"/>
 <transition to="end" name="toEnd"/>
 </task-node>

 <end-state name="end"/>

</process-definition>

However...as you can see in the evaluateLeave decision i am at this page where the user needs to know whether they'll get leave or not.
however programmatically how do i know at which node is the token at???
getRootToken() gives the the root token..but i want the current token.
so that i can get the name of the token...and say if is in the token 'giveDonuts" then perform a different behavior

just look a little deeper at the api. you can retrieve the children of a token

I think that this is what you are looking for:

context.getToken().getName();

where context is the ExecutionContext in you ActionHandler

Remember if you don't have concurrent paths of execution(like if you use a fork) or a subprocess(like if you use a process-state), you only have one token.. and that token have a pointer to the current node.

Hope it helps

Thanks..
I actually found a way..
the context.getToken().getName() works only when you have access to ExecutionContext
However I had this managed bean (JSF world) that had access to ProcessInstance..
the way i found my current token is via..

processInstance.getRootToken().getNode().getName();
