Oracle ADF - double call to doDML() in EOImpl.java

Question

Hi All,
I am using Oracle jDev 11.1.1.4.0.
In my application I have Add, Edit, Submit and Cancel buttons.
*Add new customer in the database:
Steps: Click on Add - fill the form - click on Submit...
Now, doDML() from EOImpl gets called and first time operation is DML_UPDATE...
It considers very first record from database and executes query on first record but not on the record which I have just added.
Again, it immediately calls the doDML() from EOImpl and now this time operation is DML_INSERT.
Now, the record which I have added is inserted into the database.
But, why there is * automatic double call to doDML()!!!*
I am confused!!!
Appreciate your help.
Thanks,
Madhav

Hi,
When I debug my application.
I found that, while inserting new record into the database; when control goes
into EOImpl class the value of operation is 2 that's why it considers operation as DML_UPDATE.
and second time it get's the operation as value 1.
protected void doDML(int operation, TransactionEvent e) {
//for first time operation has value 2
//so it updates the first record from the database.
//and second time it has value 1...now new customer get's inserted into the database....
Why that operation has value of 2, even if I am doing CreateInsert operation; which has value 1.
Foll is the code in bean on Add button click,
        ahId.setValue(0);//this is primary key in table. I kept it hidden field in jspx and set to zero here.
                                //On jspx, I dragged and dropped it from respective VO....
                                //then in Impl I am fetching MAX AH_ID from database table and adding 1 to it for new customer ID.
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding =
            bindings.getOperationBinding("CreateInsert");
        operationBinding.execute();and
Foll is the code in bean on Submit button click,
        BindingContainer bindings = getBindings();
          OperationBinding operationBinding =
              bindings.getOperationBinding("Commit");
          operationBinding.execute();
Where does that operation ( parameter for doDML() ) value set's actually?
Please help.
Thanks,
Madhav.
