[jbpm-issues] [JBoss JIRA] Created: (JBPM-2296) Fork activities create the wrong type of child executions
Fork activities create the wrong type of child executions
---------------------------------------------------------
Key: JBPM-2296
URL: https://jira.jboss.org/jira/browse/JBPM-2296
Project: JBoss jBPM
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Runtime Engine
Affects Versions: jBPM 4.0.0.Beta2
Reporter: Alexis Seigneurin
Attachments: sbox-creation.jpdl.xml
With fork activities, child executions are created by calling
executionImpl.createExecution (ForkActivity, line 56). In the end,
ExecutionImpl.newChildExecution() creates an instance of ExecutionImpl. The issue is that
this method should be redefined in the JpdlExecution class.
You get this error:

To fix it, in JpdlExecution, add this:
protected JpdlExecution newChildExecution() {
return new JpdlExecution();
}
