impdp ora-39082 on 10.2.0.4

Hi,All

I executed
"expdp usrname/passwd dumpfile=dumpname.dp logfile=imp.log"
then scp the dumpname.dp to another host then execute
"impdp usrname/passwd dumpfile=dumpname.dp logfile=imp.log"
there were some warnings below:

---

ORA-39082: Object type TRIGGER:"MMM"."TI_DI_TP_DEF" created with compilation warnings
ORA-39082: Object type TRIGGER:"MMM"."TU_AI_DEFINE" created with compilation warnings

---

Then I checked the triggers PL/SQL code:
(1) ":NEW" changed into ":EW"
(2) "sql_str"(a variable defined in trigger MMM"."TI_DI_TP_DEF") changed into "sql_sr"
(3) "END IF" changed into "ND IF"

I check the code in source database, it's all right...
