Concrete examples are a great teaching tool, but unless you eventually teach the concepts behind the examples, your students are incapable of applying their knowledge to do anything beyond what they can glean from the examples example. It's like teaching math purely through example with no theory: your students may be able to pass your tests, but they won't understand what they are doing and come next year they won't be able to build on what they learned.
I'm finding the lift book sorely lacking in teaching concepts, and because of that I'm having an all but impossible time learning what is actually possible in lift. I I am not the kind of programmer that just copies and pastes other peoples' examples. I want to understand my tool and use it to it's fullest potential. When the lift book describes how pages are rendered, as if teaching a concept, and leaves out essential details like what scope templates are actually searched in, how am I supposed to understand how Lift works without posting to this mailing list or reading the source code? I wasted a couple of hours reducing my problem down to the simplest test case, and this is not the first time since learning lift where I've wasted so much time only to learn that either something doesn't work or doesn't work the way I thought. I'm pretty sure that had I picked rails or django for my pet project I would have been done already. Is it simply that Lift is too cutting edge for me? Am I the only one wasting hours of time learning how Lift and other Java tools work rather than getting my app written? I'm sorry if I sound frustrated. It is not just Lift I am struggling with. It's the whole stack I'm trying to learn! I am just getting immersed into the Java world again during my spare time. JAXB (especially JAXB!), buildr/maven/ant, Jetty, Scala and it's Eclipse plugin, Lift, each one of these tools has taken up hours of my time as I struggle to do what I thought I could do easily by reading about the tool or reading the tool's documentation. I am grateful for your response though and will take time to learn more about what the sitemap means in Lift. - Sean Reque On May 30, 2:56 pm, "marius d." <marius.dan...@gmail.com> wrote: > To access a page you need to add it in the SiteMap.
