Error loading aggregates

Hi

I'm getting the following error when trying to call repository.load()
method to load the aggregate:

java.lang.IllegalStateException: Aggregate is already initialized

This is my configuration:

<aop:aspectj-autoproxy/>

     <axon:annotation-config/>

     <context:component-scan base-package="org.axon.sample" />

     <axon:command-bus id="commandBus"></axon:command-bus>
     <axon:event-bus id="eventBus"/>

     <axon:filesystem-event-store id="eventStore" base-dir="D:\Java
\Workspace\axon-sample\resources\eventstore"/>

   <axon:event-sourcing-repository id="workShiftRepository"
       aggregate-type="org.axon.sample.domain.aggregates.WorkShift"
                              event-bus="eventBus"
                              event-store="eventStore">
           <axon:snapshotter-trigger event-count-threshold="50"
snapshotter-ref="snapshotter"/>
   </axon:event-sourcing-repository>

  <bean id="snapshotter"
class="org.axonframework.eventsourcing.SpringAggregateSnapshotter">
        <property name="eventStore" ref="eventStore"/>
        <property name="executor" ref="taskExecutor"/>
    </bean>

    <bean id="taskExecutor"
class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
        <property name="corePoolSize" value="2"/>
        <property name="maxPoolSize" value="5"/>
        <property name="waitForTasksToCompleteOnShutdown" value="true"/

    </bean>

Code to add and load the aggregate:

ApplicationContext ctx = new
ClassPathXmlApplicationContext("applicationContext.xml");

    CommandBus commandBus = ctx.getBean(CommandBus.class);

    CreateWorkShiftCommand createWorkShift = new
CreateWorkShiftCommand(new StringAggregateIdentifier("3"),
        "N/A", new Date(), new Date());

    //commandBus.dispatch(createWorkShift, NoOpCallback.INSTANCE);

    UpdateWorkShiftCommand updateWorkShift = new
UpdateWorkShiftCommand(new StringAggregateIdentifier("3"), "New
name");
    commandBus.dispatch(updateWorkShift);

Thanks

Hi Nedo,

sounds like there is something wrong inside your aggregate (org.axon.sample.domain.aggregates.WorkShift).
It’s likely that the “WorkShift(AggregateIdentifier)” constructor has an “apply(…)” statement inside it. The GenericEventSourcingRepository expects that constructor to leave an uninitialized aggregate.

Cheers,
