[Lift] Re: Where are the dragons hiding?
Is Lift suitable for web for mobiles? Generally web for mobiles (especially in Japan) has some characteristics: * No JavaScript support * No cookie support * Non standard HTML tags Thanks I think this thread contains the key dragons in Lift. Basically, it boils down to: Lift is highly stateful... that has its pluses and minuses. We're working on mitigating the minuses (session replication and persistence). -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Where are the dragons hiding?
It should be just fine. You can tell lift to not use Ajax or any JS at all. There are some flags in LiftRules to do that. LiftRules.setAutoIncludeComet = false; LiftRules.setAutoIncludeAjax = false; Besides that just don't use JS in your markup or don't use Lift's ajax stuff. Lift works with no cookies. Turning off cookies from container would automatically make Lift to use url-rewriting and put jsessionid in urls. You should be able to use XHTML MP with no problems.

The functions are retained for the duration of the session. This will not likely cause an issue on mobiles and the usage is not likely to produce a lot of pages/forms during a given session. /Jeppe -- You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Where are the dragons hiding?
If I may .. this statement is confusing leading to incorrect interpretation. Lift works with MySQL as ANY Java application. Harry may have referred to Lift's Mapper framework which for MySql may be some problems that I'm not aware of. But if MySQL becomes critical for you I'm sure things can be prioritized.

See this thread: http://groups.google.com/group/liftweb/browse_thread/thread/4a174ecf34873967/ In which we discuss how certain queries generated by Mapper perform very poorly on MySQL. Certainly this problem could be addressed, but until it is using Mapper with MySQL will be problematic. -harryh -- You received this message because you are subscribed to the Google Groups Lift group.

Hi, Marius wrote: On Nov 18, 6:31 pm, Paul Butcher p...@paulbutcher.com wrote: I'm seriously considering Lift for a new project. I know what the benefits of Scala and Lift are (that's why I'm seriously considering this as a route forwards :-) What I'm wondering is whether there are any lurking nasties that I should be aware of (so that I can avoid learning about them the hard way). Not sure if there is any. One thing though Lift's session state is kept in memory and not serialized in the DB. Session serialization is a bit tricky since we keep the bound functions on the session state. Those functions are in many cases anonymous function that may hold other references which are not serializable. Even if everything is serializable using Java serialization is likely suboptimal. But keeping the sessions in memory and have a session affinity load balancing is a very good choice from performance perspective. There are people playing around with Terracotta (http://www.terracotta.org/web/display/orgsite/Platform) and Lift. There seems to be some success regarding actors running on a cluster. No idea if Terracotta plays well with Lift session handling. There's only an unanswered post in the ML archive on that.
