Action for reading the task variables and the task instance

[aroeder]

I try to write a custom action class to read the variables of a task and also the task instance id. So basicly I did that:

<task-node name="INDEX_DATA">
<task name="enterIndexData">
 <controller>
 <variable access="read,write,required" name="title"></variable>
 <variable access="read,write" name="agentNumber"></variable>
 <variable access="read,write,required" name="type"></variable>
 <variable access="read,write,required"
 </controller>

</task>
 <transition to="process_end" name="next">
 <action class="de.firstdata.jbpm.action.LogTimesAction">/action>
 </transition>
</task-node>

In my action class I can read the variables with:

executionCtx.getContextInstance().getVariable("title");

But I also need the task instance id, but when I call:

TaskInstance taskInstance = executionCtx.getTaskInstance();

the TaskInstance is already null.

Is there a way to find out the task instance id?

I found a solution for my problem. Here it comes:

<event type="task-end">
 <action class="de.firstdata.jbpm.action.LogTimesAction"></action>
</event>

and the task variables I read like this:

taskInstance.getVariable("title");
