the ajax example apps (probably AjaxExample2) has an example of
bidirectional communication with the server components ... i would
look at that first.

Yep in fact, I sent a string 'To the server' , and it was printed in
the application console no problems, so I need to send the right
data, the quesiton is then, what should I send there, a JS Array?,
if so what should I have as parameter in the method? or should
create an Array and then convert it to a JSON and then send it to
the server, and in the server put as parameter a JSONObject?... this
is what I dunno ..
Thx

it look like the json format used to pass values from the browser
to the server was misinterpreted by the json bridge on the server.
Maybe it was invalid json sent to the server.
I would look at what is the actual data sent to the server and tune
it to make sure it get translated to the object class you really
want on the server.

Hello.
Im usign the AjaxProxy Wonder component, Im receiving data alreayd
from the
server, and Im generating a grid using EXTJs, now when I select
rows in the
grid, and then I click an AjaxSubmitButton, I have the following.
<wo:AjaxSubmitButton id = "reassign" class = "moreButton" action =
"$reasignSelections" value = "Reasign To Translator" onComplete
="reassignToUser()"/>
so in the action binding method Im doing nothing so far, jsut
returning
null.
in the JS reassignToUser() Im doing the follwoing:
var records = window.grid.selModel.getSelections();
json.translations.reassignToTranslator(records);
but Im getting JSONRpcClientException: invalid or unexpected data
in fixups:
unexpected exception, in the Safari debugger Console, and a:
ep 11 14:33:44 XWSLocalizer[51417] ERROR
org.jabsorb.JSONRPCBridge -
unexpected exception
JSONException: JSONArray[0] not found.

... skipped 15 stack elements
at er.ajax.AjaxRequestHandler.handleRequest
(AjaxRequestHandler.java:17)
... skipped 6 stack elements
Im seeing that the var records in the JS has actually data, and
its an array
with a lot of stuff, but here are the objects in positions 0 - n,
now, I
guess this is more about EXTJS, but inside each Object in the
array, there
are many more stuff, but there is a data property and a toJSON,
which
contains my values, ... so how to send and NSArray back to the
srever with
this information?, and what to di in case its a lot of data?m I
was thinking
in making a for loop to generate an arrya with the data, and to
the server,
but what if there is a lot of data?, is there a way to do this
"magicaly"
:P.
So I guess the error Im getting, its because Im not sending the
right Object
type.
Thanks
Gustavo
