Cannot commit updates

Question

work in jdev 11.1.2.3
I create a EO/VO and drag and drop the data control to a jspx page with SUBMIT button.
and also I drap and drop COMMIT, ROLLBACK button into the same page from the data contral panel.
(and set the partial submit property to TRUE for these three button).
and it runs:
1.The SUBMIT is enabled, COMMIT, ROLLBACK are disabled when the page show.
2.edit some fields on the page, and press SUBMIT, and the COMMIT, ROLLBACK are enabled.
3.press the COMMIT, and it looks OK-refresh the page, shows the updated data for the fields. but I check the database in ORACLE SQL DEVELOPER. the data has not been changed yet.
Why the COMMIT cannot work?
Thanks.

Hi,Rajdeep
Thank you very much for your kindness and patience to send me the sample you created! I'v download and have a try. Here is the results:
1.Since there is a 1-1 (id,id) relation between VO1 and VO3, we cannot create new records for VO3 without violating PK constraint for EO.
so I delete all VO3 page components and re-drag and drop VO1 from data control into the page again.
--now the TREE display and adf-FORM components are all based on the same VO1, and also add createinsert, delete button for the page.
and to my suprise, the newly created adf FORM components include all attributes from EO (employeeid,firstname,lastname,departmentid,email,hiredate...)
--but the VO1 query only include 3 attributes (employeeid,firstname,lastname)
-- and these three attributes can be seen under the DATA CONTROL structrue tree.
and I went on..
2.At the EmployeesEO attributes tab page, set the EmployeeId.type to DBSequence.--to create PK- employeeid automatically.
3.Run the testView.jspx page.
all seems ok even now:
--the TREE at left panel display rightly.
--the navigate button functions rightly for the right panel's emp form.and the records can be synced between the tree and the form.
--DELETE->SUBMIT->COMMIT is ok.
--edit some field ->SUBMIT-COMMIT is ok.
but when I press CREATINSERT :
--only three fields(employeeid,firstname,lastname) left on the page, others dispeared, and empoyeeid = -2,
--press SUBMIT, warnnings to fill required fields showed: email,hiredate,jobid are requiring input.
--press SUBMIT again, all fields(more than the above three) appeared again now. and filling all fields.
--press SUBMIT again, no warnings.
--press COMMIT, an error popup showed: ORA-01400: cannot insert a NULL ("HR"."EMPLOYEES"."EMPLOYEE_ID")
ORA-06512: 在 line 1.
--change employeeid = 2,
--press COMMIT again.
--data were saved succussfully now.
BUT there are must have something wrong in the above process.
and if i :
At the EmployeesEO attributes tab page, set the EmployeeId.type to integer.
and run Test.jspx:
the tree and form cannot display correctly nowand there is an error on the log file:
java.lang.ClassCastException: java.lang.Integer cannot be cast to oracle.jbo.domain.DBSequence
Can you help me further to solve these problems?
Thank you again.
BAO
