Description

does anyone think that tags/ognl should re-throw runtime exceptions and let the container catch them instead of just just logging them how it is now and continuing to load the page normally?

I was using a previous version of webwork2 and this wasnt happening before.

what im doing is loading a proxied object from hibernate in my action then going to the view to display it but its throwing an ObjectNotFoundException when the tags try to access the proxy, I would have thought that hibernate would throw that ONFE when I did the actual session.load() instead of when I actually tried to use the proxy but thats not the case.
