I can't make any guarantees, but this is something we're trying to address with the upcoming Record framework. The other thing is that you can mix the two if there are certain things you like about Mapper (say, MegaProtoUser). Derek On Tue, Mar 24, 2009 at 2:18 AM, Alex wrote: > > I decided aga

Perhaps this debate has been had before but I didn't see it. I have a feeling this might be contentious. Doesn't this violate the basic tenet that you should not use server side state when you don't have to? There is no reason for instance when someone is submitting a news group posting to bind

In Scala, imports are relative, unless you make them absolute. In this case, your package is main.scala.com.liftworkshop.snippet The: import scala.xml.{NodeSeq} tells the compiler to look for _root_.main.scala.xml.NodeSeq That is not found. There are two ways to deal: 1. Change your package

The general case is that a page won't link to itself, I think, which is why the default isn't to show it when the page matches. Unless anyone has objections I can add an "always" attribute. As for #1, the Menu.item makes a link using whatever the contents of the Menu.item tag are for the link text:
