[Lift] Sending malformed HTML in custom dispatch
I'm using custom dispatch (to handle both XML & media files). Often, I will want to send a page that contains user-inputted (X)HTML. This will often be malformed HTML that is nevertheless rendered fine by a modern browser. How would I send this through? I tried PlainTextResponse, but it sends the wrong mime type and shows up as well... plaintext. And XHtmlResponse requires valid XHTML. Is there any response that sends a String and "claims" that it's (x) html? -- You received this message because you are subscribed to the Google Groups "Lift" group.

I think the best things I think you could do to help newbies is document in a well-structured way: * all the conventions over configuration rules * what classes to use for the basic stuff (what is S for and how it should be used, all the things you can do with LiftRules, etc.) * more advanced uses of bind(...) in snippets * better docs for the Lift tags.

Well, I'm not sure if I completely get it yet or if I can summarize well enough, but: I should look at Lift through more functional programming goggles, some things in it don't make a lot of sense when looked through OO goggles. >From looking through some of the docs, examples and sources, I have a basic understanding now about how the requests are served: what rules can be defined in LiftRules during the Boot process and by what conventions templates, snippets and other stuff are looked up. I don't know how to summarize it though. Erkki L On Dec 25, 4:51 pm, greekscala wrote: > Hello, > > I would like to hear more about, how you "get" lift.

I mostly agree with what David said and I'll add this: * I think _? and _! in methods come from Ruby, but they don't fit the naming conventions in Java/Scala (I think Scala should mostly follow Java conventions with some exceptions). This is a really minor point though. * object User extends User with MetaMegaProtoUser[User]. ProtoUser should just go away, the namings are ridiculous and it mixes HTML with persistence. Luckily one can just ignore the whole mapper module. * Some exceptions seem to just get eaten and I have no idea where things went wrong * I haven't taken a closer look at Box yet, but I understand that they are like Option, but have a third possibility of capturing an exceptional situation. Is this really better than using Exceptions? While Java's checked exceptions may have proven to be a failure, I don't think it's necessary. * there are several classes that have lots of methods in them that don't all belong together. For example: S, LiftRules, I'm sure there's more. Some packages have too many classes as well. I think there should be a cleaner separation of concerns. * I find Lift to be generally concept-heavy and invents new concepts instead of reusing well-known ones. You have to know much to use it effectively. I do not think Lift in it's current form is usable for "average" developers. Maybe that isn't the goal, but this makes me think there should be a post-Lift framework that takes all the good things, makes it better structured and documented and generally more usable by "normal" people :) Disclaimer: a lot of this might come from the fact that I'm not very used to functional programming.

Re: [Lift] Netbeans 6.8 issues with Lift
That would be because the 6.8 plugin uses scala 2.8 which we do not support.
See some of the recent threads on the mailing list.

[Lift] Netbeans 6.8 issues with Lift
Hello guys,
I have upgraded my Netbeans from 6.7 to 6.8 and the very same Lift code started
to report some errors. The code compiles correctly from the command line, but
it reports error in the GUI. One of the errors is the following:
This method:
def dispatch: LiftRules.DispatchPF = {
case r...@req("api" :: "feed":: "getNewSources" :: Nil, "", PutRequest)
=>
() => getNewSources(r)
case r...@req("api" :: "feed":: "getNewFeedsPerSource" :: Nil, "",
PutRequest) =>
() => getNewFeedsPerSource(r)
case r...@req("api" :: "feed" :: "setNewSource" :: Nil, "", PutRequest)
=>
() => setNewSource(r)
case r...@req("api" :: "feed" :: "setNewFeedEntries" :: Nil, "",
PutRequest) =>
() => setNewFeedEntries(r)
}
Reports:
missing parameter type for expanded function
As I say, the code complies and run perfectly from Maven in the command line.
Does anybody have similar issues with Netbeans 6.8?
Thanks in advance,
GA
