Value Type :  Expression

Value :
(new oracle.jbo.server.SequenceImpl("HR.XX_IMAGE_S",adf.object.getDBTransaction())).getSequenceNumber()

Other options mentioned in

For Programmatic Approach
in EoImpl

import oracle.jbo.server.SequenceImpl;
...
protected void initDefaults() {
super.initDefaults();

SequenceImpl sequence = new SequenceImpl("<YourSequenceName>",getDBTransaction());
DBSequence dbseq = new DBSequence(sequence.getSequenceNumber());
OR
Number seqValue = (Number)sequence.getSequenceNumber();
populateAttributeAsChanged(<YourId>,dbseq
}




OR

Inside  EOImpl Class
@Override
public void create(AttributeList attributeList) {
super.create(attributeList);
SequenceImpl seq = new SequenceImpl("LOG_SEQ", getDBTransaction());
Number seqNextval = seq.getSequenceNumber();
setId(seqNextval);
}
