Hi,
I have the following process definition:
<?xml version="1.0" encoding="UTF-8"?>
| <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="spa-process">
|
| <start-state name="Start">
| <transition to="publish_node" name="to_publish_node"/>
| </start-state>
|
| <node name="publish_node">
| <action expression="#{publishManager.publish}"/>
| <transition to="input_data" name="to_input_data"/>
| </node>
|
| <task-node name="input_data">
| <transition to="published" name="to_published"/>
| </task-node>
|
| <end-state name="published"/>
| </process-definition>
I need to know how to propagate the execution of the process after the
execution of the method 'publish()', in order to go to task 'input_date'. I
already tried a lot of different ways, but none of them worked:
I tried to Inject the BusinessProcess in the PublishManager object:
@In
| private BusinessProcess businessProcess;
|
and in the end of publish() method calls:
businessProcess.transition("to_input_data");
but when this line is executed I got the exception (this is the bottom of stack
trace, the whole thing is enormous):
