A few other options:
- Do you use a language that can be used in the pagegroup? if not the select statement he uses will not find any data => try to switch to a language that was published for this pagegroup.
- Just to make sure, can you make a select statement to the wwv_user_corners tabel from the schema in which you have installed the portlet?
- dig into the html source code where you have put your menu on and try to get the url of the tree and open it(search render_tree_items), check if any values have been created for the menu.
If this is empty you should try this select statement and try to find out what causes it not to give back any values:
select level, siteid, id, title, parentid from wwv_user_corners t1
where t1.siteid = '||p_siteid||'
and t1.is_template != '||wwpob_api_page.PAGE_TEMPLATE_YES||' -- 0
and t1.type not in
('||wwpob_api_page.PAGETYPE_TAB||' ,
'||wwpob_api_page.PAGETYPE_MOBILE||' ,
'||wwpob_api_page.PAGETYPE_NAV||' ,
'||wwpob_api_page.PAGETYPE_CAT_PERS||'
and t1.language = '''||p_lang||'''
start with id = 1 and siteid = '||p_siteid||' and language = '''||p_lang||'''
connect by prior id = parentid and siteid = '||p_siteid||' and language = '''||p_lang||'''
order siblings by title;
