Task UWL is text instead of hyperlink.

Hi SAP Portal's gurus

This is Victor, I use Universal Work List in SAP Portal. Sometimes the task (ítems) of the UWL appear as text instead of hypelink.

The user can't work with the task.

I have a workaround for the issue. I deactivate and Re-Register the system.

I don't understand why the issue appear in different times.

What is the problema?

Best regards,

Victor Carmona
