Why does view WWSBR_USER_FOLDERS return no rows to public ?

Question

Hi,
I want to show a user dependent list of folders in a portal
report application component, but the view
portal30.wwsbr_user_folders does not show public folders to a
public (not logged in) user. The view does not return any rows. I
tested this by creating a portal report on the view, put the
report as a portlet on page. Logout and navigate to the page. The
report portlet shows "No Rows Returned". I would expect to see
the public folders in the report portlet. Am I doing something
wrong ? Is view portal30.wwsbr_user_folders the right view for
this kind of query ?
Environment:
9iAS version 1.0.2.2
Portal patch 3.0.9.8.1
RDBMS version 8.1.7.1.1

This is a bug. As a workaround, create two new views as follows:
create or replace view wwsbr_user_corners2 as
SELECT "ID","SITEID","LANGUAGE","PARENTID","NAME","TITLE","SETTIN
GSSETID","SETTINGSSETSITEID",
"ISPUBLIC","IMAGE","ROLLOVERIMAGE","TITLEIMAGE","LEADER","DESCRIP
TION",

ATOR","SEQ",
"PUBLISHDATE","DISPLAYLEVEL","DISPLAYSUBCORNERS","ICON","LIFETIME
HITS","CTXTXT",
"NAVIGATIONCORNERID","ISTEMPLATE","ISPROJECT","HAVEITEMSECURITY",
"ITEMVERSIONING",
"DISPLAYINPARENT","TOPICID","TOPIC_SITEID","VALUE","NAVBARSITEID"
,"TYPE","TYPE_SITEID",
"BASE_TYPE","FOLDER_PATH_DISPLAY","MAILTO_LINK_DISPLAY","IS_CACHE
_VALID",

The first view adds the condition (WHERE ISPUBLIC=1) to show any
public folder.
Don't change the original view definitions, and be sure you
grant access on WWSBR_USER_FOLDERS2 (or whatever you choose to
call it) to PORTAL30_PUBLIC (or whatever your public portal
schema is called).
