Getting Errors while setting the Transformation Function

Question

Hello All,
I was trying to attach a Transformation function to existing capture process.
But I am getting ORA-30625 error while I was trying to set my transformation function to one of the
DBA rule_names.
Following are details:
SQL> select rule_name from dba_rules;
RULE_NAME
TEMP1
TEMP3
TEMP5
TEMP7
SQL> DECLARE
2 action_ctx SYS.RE$NV_LIST;
3 ac_name VARCHAR2(30) := 'STREAMS$_TRANSFORM_FUNCTION';
4 BEGIN
5 SELECT RULE_ACTION_CONTEXT
6 INTO action_ctx
7 FROM DBA_RULES R
8 WHERE RULE_OWNER='STRMADMIN' AND RULE_NAME='TEMP1';
9 action_ctx.ADD_PAIR(ac_name,
10 SYS.ANYDATA.CONVERTVARCHAR2('hr.transformation'));
11 DBMS_RULE_ADM.ALTER_RULE(
12 rule_name => 'strmadmin.temp1',
13 action_context => action_ctx);
14 END;
15 /
DECLARE
ERROR at line 1:
ORA-30625: method dispatch on NULL SELF argument is disallowed
ORA-06512: at line 9
Can any body suggest me what to do...
Thanks in advance.

Hello
I added the line you suggested, Compiling is done successfully, But Capture process
is not invoking the Transformation function that I have assigned to it.
Transformation function I am using is :
create or replace function scott.transformation (in_any IN SYS.AnyData)
RETURN SYS.AnyData
IS
rc NUMBER;
BEGIN
insert into scott.log values ('abc');
return in_any;
end;
1) Any extra initialization parameters are required..?
2) My Streams environment is having only a Capture process for capturing changes. There are no other
components like propagation, apply.
Appreciating your suggestions.
Thanks in advance.

Put the following line
action_ctx := SYS.RE$NV_LIST(SYS.RE$NV_ARRAY());
on the line immediately preceding the call to ADD_PAIR.
This should allow the pl/sql function to compile successfully.
