[JIRA] (JENKINS-15342) NullPointerException in workflow editor trying to move Jenkins task

Thu, 27 Sep 2012 16:25:53 -0700
Issue Type: Bug Bug
Assignee: Max Spring
Components: jenkow-plugin
Created: 27/Sep/12 11:24 PM
Description:

It's not clear if this is a bug in your Activiti designer extension or a bug in Activity designer itself, but while I was playing with the workflow, I somehow managed to create one Jenkins task that refused to be moved.

When I try to drag the task, I get the following NPE:
