Tree error, after Expand All, then collapsing any node, ORA-6502/6512

Question

Has anyone seen this problem with the Tree?
Normal Tree mode works great, can expand and collapse nodes with no problem.
I can Expand All, Collapse All, and Reset Tree without problems.
However, if I select Expand All, and then try to collapse any node, I get this error.
Unexpected error ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at line 1
My database is 9.2.0.4, and there are 1,138 records in my tree table, with id NUMBER(8), pid NUMBER(8), and name VARCHAR2(100).
my tree query is:
select "ID" id,
"PID" pid,
"NAME" name,
'f?p=150:2:&SESSION.::NO::P2_PARAM_ID:'||"ID" link,
null a1,
null a2
from "#OWNER#"."PARAM_TREE"
order by 3
My root tree query is:select "ID" id, "PID" pid, "NAME" name, null link, null a1, null a2 from "#OWNER#"."PARAM_TREE" where id=0
I checked the link to collapse, it was the same in normal mode or Expand All:http://umbriel.xxx.com:7777/pls/EDIWS_GUI_DEV/f?p=150:1:9757663040679228582:CONTRACT,69
Any ideas, I searched in the forum, saw something on 9.2.0.6 that sounded similar, but it was specific to 9.2.0.6, not 9.2.0.4..
Thanks, Joe

Hi all,
I have created a tree with over 20000 entries but I dont know how many nodes there are. I am using APEX 3.0.1.
Whenever EXPAND ALL ist pressed I am getting this error:
Unexpected error ORA-06502: PL/SQL: numeric or value error: character string buffer too small.
I am also using DIV together with javascript in the tree region so that the selected node is always on top of the page.
like you mentioned. Does this seem like a bug too you?
