ADF: Inserting data into parent table and using parent id insert data into child table in ADF.

Step 1 :

Create a sequence .

CREATE SEQUENCE id_seq
  start with 1
  increment by 1;

Step 2 :

Create EO and VO using database table.Edit Entity Object id and select value type as expression and put the bellow value.

(new racle.jbo.server.SequenceImpl("id_seq",adf.object.getDBTransaction())).getSequenceNumber().

Step 3 :

Create form using view object in datacontrols in jsf page and add createInsert,commit,rollback actions bindings to page.
In save button action listener write bellow code

         DCBindingContainer bindings =
            (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
   //     int id =((BigDecimal)JSFUtils.resolveExpression("#{bindings.Id.inputValue}")).intValue();
  int id =((Number)JSFUtils.resolveExpression("#{bindings.Id.inputValue}")).intValue();
        DCIteratorBinding roleIter =
            bindings.findIteratorBinding("EmpVO1Iterator");
        ViewObject obj = roleIter.getViewObject();
             Row newRow = obj.createRow();
             newRow.setNewRowState(Row.STATUS_INITIALIZED);
            newRow.setAttribute("deptId", id);
            newRow.setAttribute("EmpId", "some value");

            obj.insertRow(newRow);
        }
         executeMethodBinding("Commit");

Note :

If any one got bellow exception change datatype of ID number to Bigdecimal in EO
java.lang.ArrayIndexOutOfBoundsException: 1 at oracle.sql.NUMBER.toBigDecimal(NUMBER.java:681).
