During configuration of the Activiti engine I am attempting to load a custom parser.The load fails with the following message:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngineConfiguration' defined in resource loaded through InputStream: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.util.ArrayList' to required type 'java.util.List' for property 'customPostBPMNParseListeners'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.kallik.wm.listeners.WorkflowManagerCustomParseListener] to required type [org.activiti.engine.impl.bpmn.parser.BpmnParseListener] for property 'customPostBPMNParseListeners[0]': no matching editors or conversion strategy found
The activiti.config.xml used is:
<?xml version="1.0" encoding="UTF-8"?>

Although I don't think its getting this far, the class referred to is defined as follows:
public class WorkflowManagerCustomParseListener implements BpmnParseListener {
private static final Logger log = Logger.getLogger(WorkflowManagerCustomParseListener.class);
/**
* {@inheritDoc}
* <P>
* Adds generic listeners for create, assignment and complete operations for all user tasks in the system.
*/
public void parseUserTask(Element userTaskElement, ScopeImpl scope, ActivityImpl activity) {
log.info("Adding listeners to all of the user tasks for workflow: " + scope.getProcessDefinition().getName());
UserTaskActivityBehavior utab = (UserTaskActivityBehavior) activity.getActivityBehavior();
log.info("Adding CandidateGroupRenamerListener listener to all of the user tasks for workflow: "
+ scope.getProcessDefinition().getName());
utab.getTaskDefinition().addTaskListener("create", new CandidateGroupRenamerListener());
log.info("Adding GenericUserTaskCreateListener listener to all of the user tasks for workflow: "
+ scope.getProcessDefinition().getName());
utab.getTaskDefinition().addTaskListener("create", new GenericUserTaskCreateListener());
log.info("Adding GenericUserTaskCompletedListener listener to all of the user tasks for workflow: "
+ scope.getProcessDefinition().getName());
utab.getTaskDefinition().addTaskListener("complete", new GenericUserTaskCompletedListener());
}
… no further concrete method implementations …
}
Can anyone give me any ideas to help solve this, please?
