what about making this a generic hook in the framework proper, for
anyone who requires transaction demarcation. After all that is not an
O/R-specific issue..

As it turns out, the only way to get around this is to change the

in continuation of the previous mail: Of yourse "new

everything that makes up a component, whereas reused

WebOGNL doing it this way (e.g. component

Does anyone else think it would at least theoretically make
sense/be possible to introduce these items into tapestry?
