Activiti explorer and alfrsco community

[dimmumeister]

Hi, I'm new to alfresco and been messing around with this MONSTER app
So I've deployed the alfresco.war and share.war under tomcat 7. I'm using alfresco community 4.2.f
after some digging I've managed to integrate the activiti explorer app with the alfresco database. I actually can log into the activiti explorer interface and see the workflow that I've launched but when go to Processes > My Instances, I get the following error:
Apr 27, 2014 6:03:43 PM com.vaadin.Application terminalError
SEVERE: Terminal error:
com.vaadin.event.ListenerMethod$MethodException: Invocation of method buttonClick in org.activiti.explorer.ui.custom.ToolbarEntry$1 failed.


anybody have any idea please?

Found the reason for this error. In activiti explorer, when a admin user logs in and deploys a process. After deployment it is redirected to a Manage processes page, which allows you to see the jobs started or allows you to undeploy a process etc. This works fine for admin user. But if the user is not admin, then he is should not be allowed to see the Manage page. But still it redirects him to that page.. and i think sine he doesn't have the permission none of the links in the page works and we get this error.
