List View Report with pipelined function in Mobile application and ORA-01007: variable not in select list

Question

Hi!
I have a problem with List View Report in mobile application (theme 50 in apex) after updating to apex 4.2.2. I created Report -> List View. I used select from pipelined function in Region Source. Then when page is running and submited three times (or refreshed three times) I get an error:
Error during rendering of region "LIST VIEW".
ORA-01007: variable not in select list
Technical Info (only visible for developers)
is_internal_error: true
apex_error_code: APEX.REGION.UNHANDLED_ERROR
ora_sqlcode: -1007
ora_sqlerrm: ORA-01007: variable not in select list
component.type: APEX_APPLICATION_PAGE_REGIONS
component.id: 21230833903737364557
component.name: LIST VIEW
error_backtrace:
     ORA-06512: at "APEX_040200.WWV_FLOW_DISP_PAGE_PLUGS", line 4613
     ORA-06512: at "APEX_040200.WWV_FLOW_DISP_PAGE_PLUGS", line 3220
I get this error only when I use select from pipelined function in Region Source (for example: "select value1, value2 from table(some_pipelined_function(param1, param2)) ").
You can check it on http://apex.oracle.com/pls/apex/f?p=50591 (login - demo, password - demo).
In this application:
- I created package TAB_TYPES_PKG:
create or replace PACKAGE TAB_TYPES_PKG IS
TYPE cur_rest_r IS RECORD (
    STR_NAME          VARCHAR2(128),
    INFO              VARCHAR2(128)
TYPE cur_rest_t IS TABLE OF cur_rest_r;
END TAB_TYPES_PKG;
- I created pipelined function TEST_FUNC:
create or replace
FUNCTION TEST_FUNC
RETURN TAB_TYPES_PKG.cur_rest_t  PIPELINED IS
r_cur_rest TAB_TYPES_PKG.cur_rest_r;
BEGIN
r_cur_rest.STR_NAME := 'ROW 1';
r_cur_rest.INFO := '10';
PIPE ROW (r_cur_rest);
r_cur_rest.STR_NAME := 'ROW 2';
r_cur_rest.INFO := '20';
PIPE ROW (r_cur_rest);
r_cur_rest.STR_NAME := 'ROW 3';
r_cur_rest.INFO := '30';
PIPE ROW (r_cur_rest);
r_cur_rest.STR_NAME := 'ROW 4';
r_cur_rest.INFO := '40';
PIPE ROW (r_cur_rest);
r_cur_rest.STR_NAME := 'ROW 5';
r_cur_rest.INFO := '50';
PIPE ROW (r_cur_rest);
RETURN;
END TEST_FUNC;
- I created List View Report on Page 1:
Region Source:
SELECT str_name,
       info
FROM TABLE (TEST_FUNC)
We can see error ORA-01007 after refresing (or submiting) Page 1 three times or more.
How to fix it?

Hi all
I'm experiencing the same issue.  Predictably on every third refresh I receive:
Error
Error during rendering of region "Results".
ORA-01007: variable not in select list
Technical Info (only visible for developers)
is_internal_error: true

OK
I am running Application Express 4.2.2.00.11 on GlassFish 4 using Apex Listener 2.0.3.221.10.13.
Please note: this works perfectly using a classic report in my desktop application; however, no joy on the mobile side with a list view.  I will use a classic report in the interim.
My region source is as follows:
SELECT description AS "DESCRIPTION", reference AS "REFERENCE" FROM TABLE(AUTOCOMPLETE_LIST_VIEW_FNC('RESULTS'))
The procedure:
  FUNCTION AUTOCOMPLETE_LIST_VIEW_FNC(
      p_collection_name IN VARCHAR2)
    RETURN list_row_table_type
  AS
    v_tab list_row_table_type := list_row_table_type();
  BEGIN
    DECLARE
      jsonarray json_list;
      jsonobj json;
      json_clob CLOB;
    BEGIN
      SELECT clob001
      INTO json_clob
      FROM apex_collections
      WHERE collection_name = p_collection_name;
      jsonobj              := json(json_clob);
      jsonarray            := json_ext.get_json_list(jsonobj, 'predictions');
      FOR i IN 1..jsonArray.count
      LOOP
        jsonobj := json(jsonArray.get(i));
        v_tab.extend;
        v_tab(v_tab.LAST) := list_row_type(json_ext.get_string(jsonobj, 'description'), json_ext.get_string(jsonobj, 'reference'));
      END LOOP;
      RETURN(v_tab);
    END;  
  END AUTOCOMPLETE_LIST_VIEW_FNC;
Thanks!
