CLASSCASTEXCEPTION DCFRAME.DATACONTROLFRAMEIMPL Error and Human Task Details do not Show in Worklist App (Doc ID 1278770.1)

Last updated on NOVEMBER 18, 2016

Applies to:

Oracle SOA Platform - Version 11.1.1.3.0 and later
Information in this document applies to any platform.

Symptoms

After upgrading to 11.1.1.3, you sometimes observe that when trying to view the detail of a Human Task in Worklist app, it sometimes shows a blank screen, and sometimes shows Apache errors. You do not observe this behavior with other applications like the EM console, or B2B console, yet they are accessed by the same Apache server.

In addition, the Apache log shows errors like the following:
