Issue/Introduction

In UVC, menu Job Runs, when trying to display the "Session Execution Graph" of a Uproc within a session but it does not work, we get this popup error

In univiewer.log, the following error appears:

|2022-04-20 09:26:46,281|ERROR||BackgroundWorker-50|com.orsyp.kmeleon.guibuilder.controller.ControllerInvocationHandler$3| 
java.lang.NullPointerException

at com.orsyp.kmeleon.swing.businessviews.controller.BusinessViewsController.updateButton(BusinessViewsController.java:613)

This only occurs with a UVC 6.10.71, with a UVC 6.9.61 the problem does not occur.

Environment

Release : 6.10.71 and superior

Component : Univiewer Console

Cause

Unknown

Resolution

This problem could not be reproduced anymore after closing and reopening the UVC Console.

Should it occur on your end, please modify the file <uvc_path>\mgr\log4j.xml of your UVC Console, replacing INFO by DEBUG as below:

Then launch again UVC and reproduce the issue, if you succeed, please open a case with Technical Support referencing this article and provide the generated univiewer.log.

We believe this problem could be a side-effect of the correction DU_AS-5180 that was added in UVC 6.10.71 and superior to speed-up the display of the Business Views and Job Chains when printers are configured in the workstation where UVC runs.
