JBO-25017:Error occurred while creating a new entity instance (URGENT)

Question

Hello, can anybody help me?
We have a project that uses BC4J business components and UIX-based web tier. The entity object that causes this problem is based on Oracle table with 'ID' key field, the value is generated by means of 'before_ins' trigger that inserts appropriate sequence's next value.
In the java EntityImpl-based class we redefine protected 'create' method of the base class:
protected void create(AttributeList attributeList)
super.create(attributeList);
SequenceImpl idSeq = new SequenceImpl("SEQ_CATPARAMETERS", getDBTransaction());
setId( idSeq.getSequenceNumber() );
The fault is in the third line - setId(...) causes the exception.
The only description of JBO-25017 I found is
http://www.ffpmp.ru/doc/rt/oracle/jbo/CSMessageBundle.html#EXC_ENTITY_ROW_CREATE, this one don't throw any light on the problem.
Oracle server version - 9.2.0.1
Oracle JDeveloper version - 9.0.3.10.35,
BC4J version - 9.0.3.10.7
Any ideas?

Roman,
It looks like you're trying to assign the Id in two places.
EITHER:
Override the create method to assign an Id when a new entity instance is created....
OR:
Define a database trigger to insert the Id (and set the "refresh after insert" attribute to true).
[Maybe the error is thrown because you're attempting to set a field which is set to refresh?]
Does that make any sense?
