any idea how resolve in anthillpro. running anthillpro server on ubuntu 10.10 knowing version on help. knowing step that's failing. assume there connectivity problem agent - either agent server or server agent. validate agent configuration seen server. it's online. in newer versions can run explicit communication test. in older versions can go agent's variable screen used pulled on each request rather cached. then go system -> server settings , find connectivity urls passed agent. ensure can hit urls - on screen - agent. if can't, agent won't able hit server's web services , see sort of connectivity error - perhaps one.

i've page datatable can considered view on table of database. fields static, others inputtext, meant modify field (in particular, fields of specific column). i press button , save whole table. in general, i'd understand how read entire table in managed bean. thanks! edit: i'll try more clear: imagine you've nxm table of inputtext. outside table, button action #{somebean.process}. i'd have, in process method, list length n , row object m fields. if understand correctly think, need save not datatable, need save rows table. jsf can use binding , when need save data, rows binding , make data operations.

this error message getting: couldn't match expected type `[(char, int)]' against inferred type `(a, b)' in pattern: (c, n) in definition of `decode': decode (c, n) = map (\ (c, n) -> replicate n c) and code decode :: [(char,int)] -> string decode (c, n) = map (\ (c, n) -> replicate n c) the pattern (c,n) has type (a,b) not match type [(char, int)] . in other words you're saying argument list of pairs, pattern matches single pair. also return value of map list of strings, not single string type signature suggests. if want single string, need use concatmap . so code this: decode pairs = concatmap (\ (c, n) -> replicate n c) pairs or just decode = concatmap (\ (c, n) -> replicate n c)

we have restful api exposed on http in natural way makes use of http status-line (status-code , reason-phrase) communicate api result client ( http://www.w3.org/protocols/rfc2616/rfc2616-sec6.html ). for example have following status line concurrency error: http/1.1 409 resource updated different user. reload , try again. it turned out messages presented end users of application built against our api meaning need localize them. i'm wondering if accepted approach in such scenarios, considering non-ascii charset of messages, or should reason phrase (status description) kept low level message , content make its' way user screen should passed in response body? there can bite later on if choose localize reason-phrase part? in case use response body pass new version of resource api client , including additional data doesn't see play nicely that. as you'll know rfc: the status-code intended use automata , reason-phrase intended human user so it...

'component manager' defines controller house keeping on routes. should able configure 2 controllers both respond s...
