APEX post restful service inserts null value

Question

Oracle APEX 4.2.5
Oracle Rest Data Service 2.0.7
Apache Tomcat 7
Oracle database 11.2.0.4
Oracle APEX PUT web service inserts null value into column. This is either a bug or the documentation does not properly cover how to correctly set PUT restful services. 
GET web services works fine. 
I have granted the role of apex_rest_public_user to both apex_public_user and the schema owner. 
The payload is a small xml document, but even a text document will yield the same result. 
I am using the Oracle REST Data Service 2.0.5
Web service code: 
RESTful Service Module: software_details/
URI Template: xml_parser
Method: POST
Source Type: PL/SQL
MIME: Types Allowed: application/xml
Requires Secure Access: NO
Source :
begin
insert into clob_test (x)
values (blob_to_clob(:body)); ## according to some online post,  :body is where APEX places any data being transferred through a web service. I have yet to find any official  ##documentation on it. 
commit:
end;
##Blob_to_clob function code
CREATE OR REPLACE FUNCTION blob_to_clob (blob_in IN BLOB)
RETURN CLOB
AS
      v_clob    CLOB;
      v_varchar VARCHAR2(32767);
      v_start      PLS_INTEGER := 1;
      v_buffer  PLS_INTEGER := 32767;
BEGIN
      DBMS_LOB.CREATETEMPORARY(v_clob, TRUE);
      FOR i IN 1..CEIL(DBMS_LOB.GETLENGTH(blob_in) / v_buffer)
      LOOP
         v_varchar := UTL_RAW.CAST_TO_VARCHAR2(DBMS_LOB.SUBSTR(blob_in, v_buffer, v_start));
            DBMS_LOB.WRITEAPPEND(v_clob, LENGTH(v_varchar), v_varchar);
           v_start := v_start + v_buffer;
      END LOOP;
    RETURN v_clob;
END blob_to_clob;
#Table code 
create table clob_test(
x clob));
Thank you,

I am experiencing the same issue.
I implemented the 'chunked file loading' example from Kris Rice's blog at Kris' blog: August 2013 in y workspace at the Oracle hosted APEX site and everything works fine.
However, I get a null value for 'data' when I implement the same example at my work site.
Work Site config is
Apache Tomcat 7
Oracle REST Data Services version : 2.0.6.27.18.06
Application Express 4.2.2.00.11
Oracle RDBMS 11.2.0.3
I am NOT using SSL at my work site. However this does not seem to affect a POST with form values.
