hi,
i want to inject processInstance in action after @CreateProcess like following code:
@Name("printSthAction")
| @AutoCreate
| public class PrintSthAction {
| @Logger Log log;
|
| @In
| private String content;
|
| @In
| ProcessInstance processInstance;
|
|
| public void printout(){
| log.info("=============> process Instance is null? #0", processInstance);
| log.info("=============> print #0", content);
| }
|
| }
jPDL:
<?xml version="1.0"?>
|
| <process-definition name="test">
|
| <start-state name="start">
| <transition name="printout" to="complete">
| <action expression="#{printSthAction.printout}"/>
| </transition>
| </start-state>
|
| <end-state name="complete" />
|
| </process-definition>
But, i got an exception like this:
| 10:31:53,653 ERROR [GraphElement] action threw exception: couldn't evaluate expression '#{printSthAction.printout}'
