Creating CTXSYS.CONTEXT type index for orddoc

Question

Hi,
We tried to create a index for a orddoc datatype , the syntax used was as below
CREATE INDEX CIX_DLX_ASSET1 ON DLX_ASSET(TEXT_ASSET.source.localdata) INDEXTYPE IS CTXSYS.CONTEXT;
where DLX_ASSET is the table name and TEXT_ASSET is of the type Orddoc.
When we tried to create the index we are getting the below error message
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: Oracle Text error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "CTXSYS.DRUE", line 157
ORA-06512: at "CTXSYS.TEXTINDEXMETHODS", line 204
But the index is being created but it is not proper and contain query doesnot work properly on it
However we were able to create an index for TEXT_ASSET.comments as below
CREATE INDEX CIX_TBL_ASSET1 ON TBL_ASSET(TEXT_ASSET.comments) INDEXTYPE IS CTXSYS.CONTEXT;
The step we had followed are as below
Granted required permission to the User owning the index.
GRANT CTXAPP to User
GRANT EXECUTE ON CTX_CLS TO User;
GRANT EXECUTE ON CTX_DDL TO User;
GRANT EXECUTE ON CTX_DOC TO User;
GRANT EXECUTE ON CTX_OUTPUT TO User;
GRANT EXECUTE ON CTX_QUERY TO User;
GRANT EXECUTE ON CTX_REPORT TO User;
GRANT EXECUTE ON CTX_THES TO User;
All the package of the ctxsys is complied
The ctxsrv has been stared as below
ctxsrv -user ctxsys/ctxsys
and is up and runing.

Dear
Here are the error explanations;
ORA-06502:     PL/SQL: numeric or value error string
Cause:     An arithmetic, numeric, string, conversion, or constraint error occurred. For example, this error occurs if an attempt is made to assign the value NULL to a variable declared NOT NULL, or if an attempt is made to assign an integer larger than 99 to a variable declared NUMBER(2).
Action:     Change the data, how it is manipulated, or how it is declared so that values do not violate constraints.
ORA-29855:
     error occurred in the execution of ODCIINDEXCREATE routine
Cause:      Failed to successfully execute the ODCIIndexCreate routine.
Action:      Check to see if the routine has been coded correctly.Ogan
