Activation creates duplicate row when primary key is populated through DB sequence (Fixed in 11.1.1.4)

We are testing if our Application Module is Activation-Safe according to:
Fusion Developer's Guide for Oracle ADF
40.10 Testing to Ensure Your Application Module is Activation-Safe
And we have many problems.
1 of them is that when we press createInsert instead of creating a new row we get the same row 2 times.

I reproduce it in a simple test case from HR schema with Countries and Locations Entities.
In Locations Entity create method I populate primary key from sequence

@Override
protected void create(AttributeList attributeList) {
super.create(attributeList);
SequenceImpl s = new SequenceImpl("LOCATIONS_SEQ",getDBTransaction());
setLocationId(s.getSequenceNumber());
}

As in
Fusion Developer's Guide for Oracle ADF
4.12.5 Assigning the Primary Key Value Using an Oracle Sequence

I check Activation-Safe by un-checking Enable Application Module Pooling in configuration.


I have a simple master Countries form and detail Locations table with CreateInsert button.
When I press CreateInsert for first time a new row is created with new sequence as locationId and I fill also other fields with values.



When I press CreateInsert again instead of getting a new rows I get 2 same rows as the first and both of them has the same new sequence as primary key.!!??


After that whatever I do on the page I get null pointer exception. (NullPointerException)
Is this a bug?
