An EF bug in ODAC 11.2.0.2.30 Beta Entity Framework

Question

use the following script to create table
CREATE TABLE MYSCHEMA.INV
INVOICENO NUMBER(38),
NAME CHAR(10 BYTE)
TABLESPACE USERS
PCTUSED 0
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE (
PCTINCREASE 0
BUFFER_POOL DEFAULT
LOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
CREATE TABLE MYSCHEMA.INVDETAIL
INVDETAILID NUMBER(38),
INVNO NUMBER(38),
QTY NUMBER(38),
AMT NUMBER(38)
TABLESPACE USERS
PCTUSED 0
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE (
PCTINCREASE 0
BUFFER_POOL DEFAULT
LOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
ALTER TABLE MYSCHEMA.INV ADD (
PRIMARY KEY
(INVOICENO));
ALTER TABLE MYSCHEMA.INVDETAIL ADD (
PRIMARY KEY
(INVDETAILID));
ALTER TABLE MYSCHEMA.INVDETAIL ADD (
CONSTRAINT INVDETAIL_R01
FOREIGN KEY (INVNO)
REFERENCES MYSCHEMA.INV (INVOICENO));
Use the following linq to query data
var context = new Entities();
var q = from m in context.INVs
select new
m.INVOICENO,
Amt = m.INVDETAILs.Sum(x => x.QTY * x.AMT)
Console.WriteLine(((ObjectQuery)q).ToTraceString());
var resutl = q.ToList();
Error ocurres.
Oracle.DataAccess.Client.OracleException: ORA-00904: "Extent1"."INVOICENO": invalid identifier
Generated sql script :
SELECT
1 AS "C1",
"Project1"."INVOICENO" AS "INVOICENO",
"Project1"."C1" AS "C2"
FROM ( SELECT
     "Extent1"."INVOICENO" AS "INVOICENO",
     (SELECT
          SUM("Filter1"."A1") AS "A1"
          FROM ( SELECT
               "Extent2"."QTY" * "Extent2"."AMT" AS "A1"
               FROM "SMART607"."INVDETAIL" "Extent2"
               WHERE ("Extent1"."INVOICENO" = "Extent2"."INVNO")
          ) "Filter1") AS "C1"
     FROM "SMART607"."INV" "Extent1"
) "Project1"
It make me very upset.
