Symptoms

In a WebCenter Spaces 11.1.1.6.6 environment, MDS customizations have been made to Activity Stream task flows and, as a result, the task flows are not working anymore. One such task flow is the activity-streaming-mainview taskflow.

The following error will appear in the browser when this task flow is used:

Internal Error (WCS#2013.04.23.15.41.20) If the error persists, report the problem to your administrator.

 In WebCenter Spaces log files the following type of error will be reported:
