SQLServer Update Trigger with empty DELETED logical table - sql-server

Question

I create a update trigger on a table to audit data changes...
the code used is:
ALTER TRIGGER dbo.Tg_table_upd ON dbo.table
FOR UPDATE
AS
DECLARE #DATA DATETIME= GETDATE();
DECLARE #USER VARCHAR(20);
SELECT
#USER = CONVERT(VARCHAR, context_info)
FROM master..sysprocesses
WHERE spid = ##SPID;
INSERT INTO table_LOG
SELECT
*,
#USER,
#DATA,
0
FROM deleted;
END;
Do some tests and its working...when I run a update in dbo.table I got 1 or more rows inserted in may audit table table_log.
But in a strange situation...when a java application run a specific update code (captured by SQL Profiler):
DECLARE #P1 INT;
SET #P1 = 68235;
EXEC sp_prepexec
#P1 OUTPUT,
N'#P0 nvarchar(4000),#P1 bigint,#P2 bigint,#P3 bigint,#P4 bigint,#P5 bigint,#P6 bigint,#P7 bigint,#P8 bigint,#P9 bigint,#P10 bigint,#P11 bigint,#P12 bigint,#P13 bigint,#P14 bigint,#P15 bigint,#P16 bigint,#P17 bigint,#P18 bigint,#P19 bigint,#P20 bigint,#P21 bigint,#P22 bigint,#P23 bigint,#P24 bigint,#P25 bigint,#P26 bigint,#P27 bigint,#P28 bigint,#P29 bigint,#P30 nvarchar(4000)',
N'update table set irc_status=#P0 where (irc_id in (#P1 , #P2 , #P3 , #P4 , #P5 , #P6 , #P7 , #P8 , #P9 , #P10 , #P11 , #P12 , #P13 , #P14 , #P15 , #P16 , #P17 , #P18 , #P19 , #P20 , #P21 , #P22 , #P23 , #P24 , #P25 , #P26 , #P27 , #P28 , #P29)) and irc_status=#P30 ',

N'YYY';
SELECT
#P1;
The source table is updated (6 rows affected)...
But I get no rows in my audit table (table_log)
Looking foward in sql profiler... I can confirm the trigger was accioned but when run the statement
SELECT
*,
#USER,
#DATA,
0
FROM deleted;
SQL profiler shows 0 rows affected... So.. the update was commited...(6 ros affected... the trigger was fired... but have a empty "Deleted" Logical table...
Why??
