Creating new entities through updatable view

Question

I am trying to create 2 entity records through an updatable view. There is one primary entity which is joined to an another entity (which is an association table).
The secondary entity is updatable and all it's attributes are updatable. But I get the following exception as soon as setAttribute() is called on the first attribute of the second entity
SEVERE: oracle.jbo.ReadOnlyAttrException: JBO-27008: Attribute set for FpsgFoId in view object FolderByName failed
javax.faces.el.EvaluationException: oracle.jbo.ReadOnlyAttrException: JBO-27008: Attribute set for FpsgFoId in view object FolderByName failed
     at com.sun.faces.el.MethodBindingImpl.invoke(MethodBindingImpl.java:150)
     at oracle.adf.view.faces.component.UIXComponentBase.__broadcast(UIXComponentBase.java:1087)
     at oracle.adf.view.faces.component.UIXCommand.broadcast(UIXCommand.java:204)
     at javax.faces.component.UIViewRoot.broadcastEvents(UIViewRoot.java:287)
     at javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:401)
Here is my code
ViewObject vo = findViewObject("FolderByName");
Row folder = vo.createRow();
vo.insertRow(folder);
Sequence seq = new Sequence("FOLDERS_SEQ", this);
Number foID = new Number(seq.getValue());
folder.setAttribute("FoId", foID);
folder.setAttribute("Name", name);
folder.setAttribute("Description", description);
folder.setAttribute("Type", type);
folder.setAttribute("ParFoId", parFolder);
folder.setAttribute("OwnerId", owner);
folder.setAttribute("FpsgFoId", foID); **** fails here ***

Thanks, but my scenario is little different. I have two entities with many to many association through an association table. Entity at one end of the association already exists. I am trying to create an entity at the other end of the association and the entity for the association record, all in one trasaction through an updatable view. The updatable view spans across the relevant entities.
ADF is trying to create the association records before creating the record for the main entity and running into foreign key constraint viloation. It should do the inserts in the opposite order.
