Activiti Explorer 5.13 - Invocation of method valueChange in org.activiti.explorer.ui.task.TaskPage$1 failed

[miketeddy]

Hi,

i'm using Activiti Explorer 5.13 in jboss 7.1.1 with postgresql-9.2-1002.jdbc4.jar and every time i perform a new start jboss and login new random tasks with lorem ipsum are generated in my task list.

The error in jboss is this:

com.vaadin.event.ListenerMethod$MethodException: Invocation of method valueChange in org.activiti.explorer.ui.task.TaskPage$1 failed.
…
Caused by: org.activiti.engine.ActivitiIllegalArgumentException: userId is null
   at org.activiti.engine.impl.cmd.GetUserPictureCmd.execute(GetUserPictureCmd.java:41)
…

This happens just after a login activiti-explorer and after a new jboss restart.

I attach my configuration in activiti-standalone-context.xml where you can see than i even disable the demo processes and i have just one simple process i made.

If i let this processes enabled, the random tasks generated are a lot more.

    <property name="createDemoUsersAndGroups" value="true" />
    <property name="createDemoProcessDefinitions" value="false" />
    <property name="createDemoModels" value="false" />
    <property name="generateReportData" value="false" />

Can anybody help-me on this?

Thanks in advanced

Hi,

can anyone help me on this?

It's hard to believe that this error doesn't happened to anyone else, because it happens every time i perform a new start jboss and login, new random tasks with lorem ipsum are generated in my task list.

Any help is apreciated

[frederikherema1]

Are you sure the demo-data generator bean is commented? and that the explorer is pointing to the right database?

[miketeddy]

I haven't commented the xml tag, but set them to fal has you can see.

I'll try to comment the all demoDataGenerator XML to see if it fixes.

Thanks

  <bean id="demoDataGenerator" class="org.activiti.explorer.demo.DemoDataGenerator" init-method="init">
    <property name="processEngine" ref="processEngine" />
   
    <!– Set following properties to false if certain demo data is not wanted –>
    <property name="createDemoUsersAndGroups" value="true" />
    <property name="createDemoProcessDefinitions" value="false" />
    <property name="createDemoModels" value="false" />
    <property name="generateReportData" value="false" />
  </bean>

I've commented the bean demoDataGenerator and now it works.

No random tasks with lorem ipsum  are now being generated.

EX:
<bean id="demoDataGenerator"


Thanks
