To keep history

Question

Hi,
My case is no deletion no updates in same record, to keep history.
1- In deletion case I set falge to show the row status,
and used this code in EntityImpl.java file to override postChange method:
public void postChanges ( TransactionEvent e )
if ( getPostState() == EntityImpl.STATUS_DELETED )
// Custom code to mark database rows
setFlage( "D" ); //"D" deactivate
else
super.postChanges(e);
2- In update case I set the revsion column, when we update a record we take its values and insert it in database with new revision.
How can we implement this business rule in BC4J?

Usama,
In case 1), BC4J do not have built in facility to mark row as "deacticate".
In case 2), version 9.0.3.3 (available on OTN around mid October), you could set the column used for update history as VERSION NUMBER History Column in Entity Wizard Attributes settings. BC4J will automatically increment this column value by 1 at post change if the row has changed.
Thanks,
