Oracle WebCenter Portal - Version 11.1.1.5.0 and later
Information in this document applies to any platform.

Symptoms

Configuring the Events Service Task Flow on a page for a group space, the Task Flow is successfully added to the page. However, when a user logs into the Spaces application and navigates to the page containing the Events Service Task Flow, the following error message is shown:

"You do not have permission to see events for this space. Contact your administrator."

The above message is received for any member of the Space and even for the Spaces application administrator.

The following errors are shown in the log files:

[WC_Spaces2] [WARNING] [ADF_FACES-60099] [oracle.adfinternal.view.faces.renderkit.rich.RegionRenderer] [host: DUB-TSTWCT-2] [nwaddr: 11.11.1.111] [tid: [ACTIVE].ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: anonymous] [ecid: 893201f3e1ae14d6:41bc8447:135aad9182b:-8000-000000000000a6de,0] [APP: webcenter#11.1.1.4.0] The region component with id: T:lang has detected a page fragment with multiple root components. Fragments with more than one root component may not display correctly in a region and may have a negative impact on performance. It is recommended that you restructure the page fragment to have a single root component.
