That was a bit vague I guess. Depending on what part of the application is being accessed. In other words, something like "No Conversation" or "Operation timed out" are fine for areas where the users are familiar with the application (administrators perhaps) but other areas might require a bit more detail. If I had a conversational search page for instance (which I do) where the user pairs down results, if that times out I'd like to provide some additional information. Something like "We're sorry, but your search is no longer active, please begin again" seems more appropriate to me for people who may not be very computer savvy and therefore might be put off if they get a confusing error message. I don't think that's something I could do right now. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3980845#...
