Using sequences in ADF-UIX

Question

Hi
I am trying to add a record to a table using the create action from the data control.
The underlying table has a sequence defined on it. Is there a way to get the next sequence number to show when the user clicks the Create button?
thanks

Answer 1

Assuming the field the sequence is pushed to is called Id, and the sequence name is ID_SEQ, override the EO's create method with the following code:
protected void create(AttributeList attributeList) {
  super.create(attributeList);
  oracle.jbo.server.SequenceImpl idSeq = new SequenceImpl("ID_SEQ", getDBTransaction());
  setId(idSeq.getSequenceNumber());
}Now when you create a record in UIX, you'll see the sequence number prepopulated in the associated Id field. You can set the field's properties to readOnly as the user no longer has to populate it.
Hope this helps.
