Expression validation error

Question

While trying to validate expression in mapping error window popups:
"java.lang.Exception: ValidationError??
java.lang.Exception: API8532: Internal Error: Language Validation can't create a unique type name when attempting to deploy a validation package."
OWB creates "owb\bin\admin\..0" file, in which there are such entries:
Wed May 21 08:14:40 CEST 2003
Executing SQL for Expression Validation:
CREATE TYPE "INGRP1_T_0";
Wed May 21 08:14:40 CEST 2003
Executing SQL for Expression Validation:
CREATE TYPE "INGRP1_T_1";
Wed May 21 08:14:40 CEST 2003
Executing SQL for Expression Validation:
CREATE TYPE "INGRP1_T_2";
and so on up to :
"Executing SQL for Expression Validation:
CREATE TYPE "INGRP1_T_50";
Wed May 21 08:14:42 CEST 2003
java.lang.Exception: ValidationError??
java.lang.Exception: API8532: Internal Error: Language Validation can't create a unique type name when attempting to deploy a validation package.
"owb\bin\admin\ValidationPLSQL.log" file contains these 51 commands with increasing number:
CREATE TYPE "INGRP1_T_0";
It doesn't matter what expression I define.
OWB is 9.0.4, Database EE 9.0.2
What can it be ?

Answer 1

Problem is it is already set to English_United States, I work only on this locale as to avoid such situations. MLS Disp. Lang. is American English.
NLS settings in database and local regional settings in client system are only different (local).
I tried validation at home, on different repository and it worked. Both databases are EE 9.2.0.1, the only real difference is server platform (Win XP there vs Linux).
From what I can see right now there are way too many problems with OWB and locales, will it be fixed in the upcoming release ?
