Why am I getting PLS - 00382?

Here is my object def:

CREATE OR REPLACE TYPE FALCON.contacts AS OBJECT (phone           VARCHAR2(50)
     ,phoneusage      VARCHAR2(25)
     ,phonetype       VARCHAR2(25)
     ,email           VARCHAR2(150)
     ,phoneext        VARCHAR2(25)
     ,anytext         VARCHAR2(250))

Here is the table def:

CREATE OR REPLACE TYPE FALCON.contacttbl AS TABLE OF contacts

Here is my pipelined function

FUNCTION get_pcontacts(p_conttbl IN xmltypedefs_spec.conttbl)
RETURN falcon.contacttbl
PIPELINED
IS
  l_contact falcon.contacts;
BEGIN
   FOR n IN 1 .. p_conttbl.count
   LOOP
      PIPE ROW(**falcon.contacts**(p_conttbl(n).phone, p_conttbl(n).phoneusage,              p_conttbl(n).phonetype, p_conttbl(n).email, p_conttbl(n).phoneext, p_conttbl(n).anytext));
   END LOOP;
   RETURN;
END get_pcontacts;

I am getting the error when I call the table function here:

FUNCTION get_pidxml(p_pidrec xmltypedefs_spec.pidtyp)

  l_tmprec                 CLOB;

PLS-00382: expression is of wrong type

Since I don't know how xmltypedefs_spec.conttbl is defined, I removed the input parameter from the pipelined function and just had it generate fake data on the fly:

CREATE OR REPLACE FUNCTION get_contacts
    RETURN contacttbl PIPELINED
IS
  -- converts some structure to pipe of contacts
BEGIN
   FOR n IN 1 .. 5 LOOP
      PIPE ROW( 
         contact( 
            '877-867-5309', 
            'Work',
            'Cell', 
            'jenny@gmail.com', 
            n, 
            'WTF?'
         )
      );
   END LOOP;
   RETURN;
END get_contacts;

The subquery now executes without error:

SELECT 
    xmlagg(
        xmlelement("contactInfo",
            xmlforest(
                phone AS "phoneNumber",
                phoneusage AS "telecomUseCode",
                phonetype AS "telecomequiptype",
                email AS "email",
                phoneext AS "phonenumberextension",
                anytext AS "anytext"
            )
        )
    )
FROM 
    TABLE( get_contacts( ) )

This tells me there is probably something wrong with xmltypedefs_spec.conttbl, perhaps in using a collection type within an SQL statement? Not sure. What if you changed xmltypedefs_spec.pidtyp to use the falcon.contacttbl instead of xmltypedefs_spec.conttbl. Seems like you've got one package type and one object type that are doing the same thing?

xmltypedefs_spec defines record types that correspond to XML elements. These record types are used to shred and build XML. Originally, the XML did not use repeating elements, but now must. I am attempting to take a table of xmltypedefs_spec.pidtyp and use the pipelined function to return 'rows' of data from an associative table. It is in this fashion that I want to send rows of array records to build xml.
