Hello everyone and thanks Cliff, actually i have a commercial application running on puremvc, and it was very good worked with it.
After one year developing that application, i´ve started others that will be sold to more than one customer.
I´ve teached puremvc to some friend that liked too, its a really ease approximation of mvc concept!

I also using fabrication thats awesome layering puremvc to few lines of code...
For those who doesn´t knows, fabrication have got live again! The creator of tequila is running it to get compatibility with flex 4!!! Tequila is another layer based on fabrication to reduce code to even fewer lines!!!

So, now my framework became more "final", i´ve got a really cool and good workflow, very good to work with all those facilities.

I wanna ask two things, first about undo management. I understand that its a little abstract thing, but i´ve seen some implementations, one from puremvc, called "undo command 1.3" (command or manager, i cant remember now), and another one intrinsic to fabrication utility... i wanna know for example from Cliff, whats the difference between the two ones, and if fabrication approximation there´s some improvement.

Another question is about VO´s and grid list.
For example, i will must do in the next days, a grid/list that will manage properties of object in a very cool editor i´m building.
Those property lists are based in some "properties" and values... i wanna know from Cliff (haha i guess thats because his 100 years of programming skills )... whats the better approximation to this... since a VO holds only the properties itself, so how to have it managing property and values? whats the best way? like some direct population of the list, or i will need two steps work, well, a mature light here would be appreciated, one time a really like to always try to do things in the best way i can try to achieve.
Thanks for everyone in this awesome forum.

hi... im near finish my first great system using puremvc... its very good to work with flex3/pmvc/amfphp/eclipse bla bla

ive a doubt

whats the best way to work with more than one vo, in a proxy?

because super initializes the "first one", so i can use setData(vo)

but
im needing to use one more VO... how its the best approx?

thanks.
Vander.

SOLVED!

instead of using mysql_fetch_array, i must use mysql_fetch_assoc

and i can use dynamic name

so the code is

:

        // function for dynamic data read, with class mapping :)
    function recolheDados ( $id, $tabela, $voname ) {
      $sql = "SELECT * FROM $tabela WHERE id_" . $tabela . " = $id";
$objeto = new $voname();
$query = mysql_fetch_assoc(_query($sql));
foreach ($query as $key => $value) {
$objeto->$key = $value;
}     
      return $objeto;
      }

hmm another strange behaviour

the result are doubled

:

(Object)#0
  0 = "1"
  1 = "vander"
  10 = "0"
  11 = ""
  12 = ""
  13 = ""
  14 = ""
  15 = "0"
  16 = "0"
  17 = "0"
  18 = "0"
  19 = "0"
  2 = "teste"
  20 = ""
  21 = "0"
  22 = "2008-06-06 13:57:55"
  23 = "0"
  24 = "0000-00-00 00:00:00"
  25 = "0"
  3 = "0"
  4 = "0"
  5 = "Vander Ferreira Hiar"
  6 = "0"
  7 = "333111222"
  8 = "0"
  9 = ""
  arquivo = "0"
  bairro = ""
  celd = "0"
  celn = "0"
  cep = "0"
  cidade = ""
  comp = ""
  cpf = "333111222"
  data_ins = "2008-06-06 13:57:55"
  data_upd = "0000-00-00 00:00:00"
  email = (null)
  end = ""
  end_num = "0"
  equipe = "0"
  estado = ""
  id_ins = "0"
  id_upd = "0"
  id_usuario = "1"
  id_usuario2 = (null)
  level = "0"
  nome = "Vander Ferreira Hiar"
  obs = ""
  rg = "0"
  senha = "teste"
  teld = "0"
  teln = "0"
  tipo = "0"
  usuario = "vander"
i cant figure out why .. since im returning only the $object why its filling with field name and index together?

i guess that im lacking of php knowledge a bit.

thanks for help.. and i have sure that it will help many ppl with the same problem!

hey cliff
got it

         function recolheDados ( $id, $tabela ) {
            $sql = "SELECT * FROM $tabela WHERE id_" . $tabela . " = $id";
         $objeto = new UsuarioVO();
         $query = mysql_fetch_array(_query($sql));
         foreach ($query as $key => $value) {
            $objeto->$key = $value;
         }            
            return $objeto;
         }
        

just one last problem
since ive created a dynamic function
how can i tell it to instantiate the correct type of object, based on table that ive passed no argument?

$objeto = new UsuarioVO();    <- how to dynamically change UsuarioVO for another VO depending of the table passed? theres no way? i will must do a switch case?

thanks for all

Yes it have much sense! ive thinked this together with your last post...

if i create a new usuariovo on php, i can retrieve it
but
do you know how can i automatize using for... to populate automatically?

very thankx cliff

:

function recolheDados ( $id, $tabela ) {
      $sql = "SELECT * FROM $tabela WHERE id_" . $tabela . " = $id";
      $teste = new UsuarioVO( );
      $teste->nome="van";
      return _query( $sql );
      }
this code is wrong.. because its returning the query... as object
but im posting to show you..
because if i return $teste.. it cames as UsuarioVO
but do you know how to create a routine that parses query and puts automagically, a iterated loop.. that puts all variables inside the object to return?

very thanks

hmmm. sounds interesting

i would like to mention that, if you take a look on the posted codes... u can see the mappings, and the explicittype definition

_query method, just returns a mysql_query method

what u said about array its true

because for me access the properties i must use
event.result[0]

and as i said previously, if i try to retrieve the properties one by one it works
like
event.result[0].nome
etc
but entirely i cant
like
usuario.usuarioVO = event.result[0]   <- doesnt work
usuario.usuarioVO.nome = event.result[0].nome <- works

its the last thing that i need to resolve.. to deliver my work too much delayed
sorry some incovenience
and much thanks cliff

ok, but, im using flex 3, and amfphp

amfphp have the service browser..

the returned stuff that im getting is:

:

(mx.collections::ArrayCollection)#0
  filterFunction = (null)
  length = 1
  list = (mx.collections::ArrayList)#1
    length = 1
    source = (Array)#2
      [0] (Object)#3
        arquivo = 0
        bairro = ""
        celd = 0
        celn = 0
        cep = 0
        cidade = ""
        comp = ""
        cpf = 333111222
        data_ins = "2008-06-06 13:57:55"
        data_upd = "0000-00-00 00:00:00"
        end = ""
        end_num = 0
        equipe = 0
        estado = ""
        id_ins = 0
        id_upd = 0
        id_usuario = 1
        level = 0
        nome = "Vander Ferreira Hiar"
        obs = ""
        rg = 0
        senha = "teste"
        teld = 0
        teln = 0
        tipo = 0
        usuario = "vander"
    uid = "DE32E9EE-167C-A123-2A43-AF06268BACB8"
  sort = (null)
  source = (Array)#2
and if i put on tree view
i see

0: (object Object) #1
     arquivo: 0
     bairro: bla bla
     bla bla bla (the fields of the bd/vo) with the correct values
 
this can help something?

thanks for attention

ive already posted all the "picks", anyway all the "confusion"
who wants a real explanation and example is ME! hehehe

however... much thanks tek... for your attention

take a look

usuarios.usuarioVO = new UsuarioVO( );
usuarios.usuarioVO.nome = note.getBody( ).nome;

this way i can update the "nome field" binding
but i wanna all the fields at the same time!!!

usuarios.usuarioVO = note.getBody( ) as UsuarioVO *! just dont work !*

i can obviously, put one by one. field by field... but.. so whats the advantage of the bindable? and we dont want to spend much time of course, writing line by line...

thanks everyone

ive tried many things

sendNotification( ApplicationFacade.USUARIOS_SUCESSO, event.result, "recolheDados" );

for example

and in the mediator ive already tried with and without creating a new vo before...

but anyway thanks for the reply, im sleeping, i MUST finish this work this weekend :S
im hoping very much that i solve this last problem with the puremvc knowledge

Hello everyone..
im 12 hours trying to discover why i cant associate in one line expression... the proxy vo object to the view vo object!

since im using bindable for the public var on view...
like this

[Bindable] public var usuarioVO:UsuarioVO;

then the text property of fields, are {usuarioVO.nome} etc.. correspondly.. ok


my first confusion starts on proxy.. with all those different approximations that i saw
ive tried EVERYTHING hehe
but
when in the mediator i try to obtain the VO
sure i can obtain it

but if i assign just one property it works...
like
usuarios.usuarioVO = new UsuarioVO;
usuarios.usuarioVO.nome = note.getBody( ).nome;

yes.. the field called nome.. update ! cool

but when i try to associate the entire stuff
NEVER WORKS.. im going mad

usuarios.usuarioVO = note.getBody( ) as UsuarioVO;
never
usuarios.usuarioVO = note.getBody( )[0] as UsuarioVO;
never

ive played too with the confusion new UsuarioVO with and without () parenthesis (UsuarioVO () and just UsuarioVO);

thats also confusing
since the VO dont have a constructor
like on some examples dont have too.. and i remember that i maybe seen someone with parenthesis

ive tried too creating a setter on the proxy
and associateing view vo directly = proxy vo
hmmm i remember that worked when i wanted to clear the fields with new VO declaration on the proxy then association...
i even got more and more lost... when i just cannot understand the getter... the constructor.. the data... the strange setdata instead sending event.result...
and tried many things and im lost... so im writing this as a last resource..
and im so convinced that this is the one of the most (if not the most) problem on the learning curve experience of this total usefull framework that cliff developed..

thanks everyone

i know by past, that examples.. but im designing my way.. ive got it it was some logic error of my part..
but all that you said is always usefull thanks cliff

now im just in one last trouble..
when i change a view on viewstack... it cames not centered... so strange huh?
i can develop a function to recentralize using width/2 etc.. bla bla

any hint?

okay, ive discovered the problem...
sorry...
it was all about... im using this event on splashscreen

<mx:Image creationComplete="inicia()"/>

ive switched it to a button, and when clicked it was dispached

ive guessed that creationComplete was fired so fast... before something become acessible
can you guess me a more 'appropriate' event?

   override public function onRegister():void
       {   
          app.addEventListener( SplashScreen.TERMINOU_SPLASH, initScreen );
      app.splashScreen.splashImage.load();
       }

ive used now a swfloader, for example, and set the autoload to false
i can load the image ok on the onregister... but can you guess me a 'good practice' to how to detect the load complete, for example.. to fire the event?

thanks cliff
