Error updating: already lock by another user

Question

Can anyone telle me how to solve the problem in the title.
At the moment of update there is only one user active
this is the code I use to make a update:
  private void updateRecord2 (Room r) throws RetrieveRecordException {
    ViewObject vo = appMod.findViewObject("RooView1");
    Object[] id = new Object [1];
    id[0] = new Integer(r.getID());
    vo.setCurrentRow(vo.getRow(new Key(id)));
    Row rw =vo.getCurrentRow();
    rw.setAttribute("Id", new Integer(0));
    rw.setAttribute("Rnumb", new Integer(r.getNumber()));
    rw.setAttribute("Capac", new Integer (r.getCapac()));
    rw.setAttribute("FlrId", new Integer (r.getParent().getID()));
    rw.setAttribute("X", new Integer(r.getX()));
    rw.setAttribute("Y", new Integer(r.getY()));
    appMod.getTransaction().commit();
}

hehe. The solution is useless, unless you are going to make an piece of software that tracks users in the building:), and you are using bc4j with a data abstraction layer with beans (to make life easier for non-oracle folk)
ps. hoe gaat ie. ik zie dat je flink aan het posten bent
