The problem with writing two spans in Scala is that one is a whole expression. So either concatenate them with ++, or surround them with <xml:group>..., which is a fake xml element to wrap a few elements as one expression.

The html/xml can be found here: http://pastie.org/787126 The question is, what is the best way to render the bound XML which i pass in ip:expand, so that upon the "actions" click, it will be rendered in the correct table on the page. I haven't figured out how a snippet might just return a string which gets passed as id/class of an html-tag. i hope you see my problem, because i am diddling around with this for like 4 hours straight and i don't find a way to simply tell it "the lift way" to do the ajax request and replace div XY. The replacing is not the problem. but how do i get an ID or something into the template where it gets rendered. It is also a mystery to me, why a snippet can't return something like <span/><span/>. I haven't found any clue on how to simply return a group of xml objects. i always need to pack around some span or god knows what to make that happen. This is especially bad if you want all the nifty "split design and code" but are not able to somehow let the user design his table because if you nest it (like i try to), you may end up with a tbody in a tbody.. these simple things are really badly documented for beginners. Mostly because i wouldn't know what that method/class i need would be called. :) best regards On 20 Jan., 21:44, Ross Mellgren <[email protected]> wrote: > Scala can't figure out what type of parameter you mean, so you need to > annotate it -- "expand" -> (fooXhtml: NodeSeq) => {... } > > Or use a separately named function with a type signature, e.g. > > def doTheStuff(ns: NodeSeq): NodeSeq) = { Log.error(ns.toStrnig); <span /> } > > bind(..., "expand" -> doTheStuff _) > > -Ross > > On Jan 20, 2010, at 3:41 PM, Franz Bettag wrote: > > > "expand" -> (fooXhtml) => { Log.error(fooXhtml.toString); <span/> }, > > > error: not a legal formal parameter (pointing at the => ) > > > On 20 Jan., 21:32, greekscala <[email protected]> wrote: > >> Hello, > > >> yes a function that takes NodeSeq parameter and returns > >> a NodeSeq :) > > >> "foo" -> (ns) => {function body} or > >> "foo" -> theCalledFunction > > >> best regards > > >> On 20 Jan., 21:26, Franz Bettag <[email protected]> wrote: > > >>> How would that look like? > >>> "foo" => nodeSeqMethod _ ? > > >>> On 20 Jan., 21:21, Naftoli Gugenheim <[email protected]> wrote: > > >>>> Meaning to the right of the -> arrow. > > >>>> ------------------------------------- > > >>>> Franz Bettag<[email protected]> wrote: > > >>>> Ah figured it out.
