[JBoss jBPM] - Exception-Handler an Transitions
by hamtho2
Hi @all,
I am calling an Action in a transition as followes
| <state name="state1">
| <event type="node-enter" >
| <action class="state1ActionHandler" name="request"></action>
| </event>
|
| <transition name="state change" to="isCancelled" ></transition>
| <transition name="invoice" to="invoiced" >
| <action class="InvoicingActionHandler" name="invoice"></action>
| </transition>
| </state>
|
As there might occur an Exceptions the InvoicingActionHandler I defined a "global" exception-handler
| <exception-handler >
| <action name="reroute node" class="ProcessFailedExceptionActionHandler" />
| </exception-handler>
|
This exception handler is perfectly called and I set the token to the source node of the transition.
| public class ProcessFailedExceptionActionHandler implements ActionHandler {
|
| private static final Logger log = Logger.getLogger(ProcessFailedExceptionActionHandler.class);
|
| public void execute(ExecutionContext executionContext) throws Exception {
|
| Node sourceNode = executionContext.getTransitionSource();
| Throwable throwable = executionContext.getException();
|
| log.info(String.format("Caught exception %s. Re-routing to source node: '%s'", throwable.getMessage(), sourceNode.getName()));
| final Token token = executionContext.getToken();
| token.setNode(sourceNode);
| }
| }
|
Unfortunately the code of the action handler defined as "node-enter"-ActionHandler of the target-node is still called, although I re-route the node manually and it should not enter the initially target node anymore. Is there a way to prevent this behaviour?
Thanks
Thomas
