Last updated on JUNE 19, 2024
Applies to:
Oracle WebCenter Portal - Version 11.1.1.8.7 to 11.1.1.9.8 [Release 11g]Information in this document applies to any platform.
Symptoms
We have a problem in the Document Explorer Taskflow in WebCenter Portal when searching on some words. This happened after we applied the last patch of WebCenter Portal and WebCenter Content with others patches too.
We do not see any errors in WebCenter Content only in WebCenter Portal, and we can't reproduce this problem in our developer machine.
When searching / filtering on a key word the page just goes blank (totally white)
We also only see the issue for some words. For example searching "teste" causes the issue but searching other words works fine.
Error seen in logs look like:
