I will present how to use ADF BC to get next value of sequence.
1- Creating Method
As we noticed in previous code that I use SequenceImpl to get sequence value.
2- Use that method at Entity Object Attribute to set default value of attribute
first set value type of attribute to Expression .
set Value as adf.object.getSequenceValue("My_seq_name").
3- Use getSequenceValue at Entity Object Impl
we can set default value to attribute of Entity Object in EntityObjectImpl class itself by overriding Create method and set attribute value to sequence value.
