I don't know whether it is adviseable to implement an "insertElementAt(Object obj , int index)" as the example below:
The entity Page has a 1-many relation to the Entity Part. I want to insert the new Part newPart into the parts collection on position number "index".
Collection parts = page.getParts();
Vector v = new Vector(parts);
v.insertElementAt(newPart , index);
page.setParts(v);
Can I do this without wrapping the collection into a Vector?
Is it possible at all to thrust the order of a Entity-relationship-collection at all or should I use somekind of indexing instead?
