Problem with a field set to refresh after insert at Row level

Question

hello all,
i have a problem with a field (a serial) which is set by a db trigger at insertion. The field "refresh after insert" is properly set in the Entity and everything is refreshed correctly when i insert data via an adf form in a jspx but when i want to insert programmatically nothing is refreshed. I insert data this way :
ViewObject insertVO = findViewObject("myView");
Row newRow = insertVO.createRow();
newRow.setAttribute("mandatoryAttribute1",value1);
newRow.setAttribute("mandatoryAttribute2",value2);
<more init here but not the serial since it will be set by the DB trigger>
insertVO.insertRow(newRow);
but when i want to get back the value with "newRow().getAttribute("TheSerial");" i always get a null back and not the value set by the db trigger.
One way to get the serial is to commit after each insert but i don't want to commit between inserts.
i've tried to unset the refresh after insert and override the createDef() method to setUseReturningClause(false) as it's is advised in chapter 26.5 of the ADF 4GL dev. guide but in this case i have an exception JBO-29000: JBO-26041.
How can i get the value back properly ?
thanks
-regards

The data for the newly created row doesn't get inserted into the database until the commit is executed, so the insert trigger isn't called.
If you need to get the value without committing, then you should implement the trigger programmatically and drop the trigger from the database. The code below shows how you could do this.
ViewObject insertVO = findViewObject("myView");
Row newRow = insertVO.createRow();
SequenceImpl seq = new SequenceImpl("MY_SEQ", insertVO.getDBTransaction());
Long next = (Long)seq.getData();
newRow.setAttribute("primaryAttribute", new Number(next));
...You will need to replace MY_SEQ and primaryAttribute with the correct values for your example, but this should acheive what you want.
