OpenSessionInViewFilter has nothing to do with detached entities, it only keeps session open till view is rendered otherwise lazy loading will no work. The filter is trying to solve it by always opening session in every request and closing it at the end. Tapestry hibernate opens session only when it is needed and closes it when thread is finished, it is how it should be, but if you use spring hibernate + tx you need to use it there is no way around it.
