Populate Primary Key with DBSequence in ADF UIX page

Question

I have a table with a trigger, so that the primary key is populated by DBSequence. My problem is, I open a ADF UIX Input Page to create a row for my table. The field of the primary key is populated by any number but not with the logical sequence number. This number appears later, when I look at a row list. So the correct number is in the database but how can this already appear on my input page???

Answer 1

You have to drop the trigger.
Then make sure you have the Id field of your entity of type Sequence.
Then go to your entity class and override the Create method.
  protected void create(AttributeList attributeList)
    super.create(attributeList);
    SequenceImpl s = new SequenceImpl("YOUR_DB_SEQUENCE_NAME", getDBTransaction());
    Number sVal = s.getSequenceNumber(); 
    setId(new DBSequence(sVal));
