Problem with exclusive gateway in multi-instance subprocess

Question

Hi,
I've recently developed a BPM process with 11gPS4 FP, the idea is simple:
1. The initiator select a set of "StakeHolders" from LDAP, each "StakeHolder" has an BOOLEAN attribute "isApprover"
2. There is a multi-instance subprocess, I used Parallel and Collection and I point the input & output array to the list selected in Initiator step
3. There is an exclusive gateway named "is approver or not" which have one unconditional sequence and one conditional sequence. In the conditional sequence I use the expression inputDataItem.isApprover == true which inputDataItem is a predefined object.
My intention is that when entering the subprocess, the stakeholders with "isApprover" is true should receive a task, but I found out that no matter "isApprover" is true or not, the expression will never become true. It always goes to the unconditional sequence. Then I tried to use some string attribute like inputDataItem.userID == "weblogic" and it works fine.
I've tried different expressions, like "inputDataItem.isApprover" or XPATH Expression but none of them work. I think it might be a bug that the gateway in a subprocess cannot use boolean type of attribute?
Has anyone met this problem before? Am I wrong somewhere or it's really a bug? Thank you in advance!

At first your configuration is not really correct.
=====================================================
In the LISTENER.ORA from 10g, you must only refer to the database and hsodbc 10g
D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = INTEGRAT)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = INTEGRAT)
(SID_DESC =
(SID_NAME = MSSQLTEST)
(PROGRAM = D:\oracle\product\10.2.0\db_1\bin\hsodbc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = pegasus.cursor.de)(PORT = 1521))
===========================================================
Then you have to create a new listener (new name) in the gateway oracle_home on a different port than instance database:
D:\oracle\product\11.1.0\tg_1\network\admin\listener.ora
SID_LIST_LISTENERGTW =
(SID_LIST =
(SID_DESC=
(SID_NAME=DG4MSQL)
(ORACLE_HOME=D:\oracle\product\11.1.0\tg_1)
(PROGRAM=D:\oracle\product\11.1.0\tg_1\BIN\dg4msql)
LISTENERGTW=
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = pegasus.cursor.de)(PORT = 1522))
To start it, use the command below:
D:\oracle\product\11.1.0\tg_1\bin\LSNRCTL start listenergtw
===========================================================
D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora:
match the DG4MSQL with the listener on 1522 port
HSODBC match with binary10g on listener 1521 port
MSSQLDG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PEGASUS)(PORT = 1522))
(CONNECT_DATA =(SERVICE_NAME = DG4MSQL))
(HS = OK)
MSSQL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PEGASUS)(PORT = 1521))
(CONNECT_DATA =(SERVICE_NAME = MSSQLTEST))
(HS = OK)
Try to configure and let me know your feedback
