DWR: error in convert from java object to javascript.

[czyjava]

Using DWR ajax, I can convert java object to javascript object, but I can't convert an object in javascript to a java object.


var setting = {id: item.Id, name: item.name, val:item.val}; //wrong, data is '[reference:c0-e2]'
var setting = {id:'1200', name: 'name', val:'ssss'};  //correct

AjaxUtil.saveSetting(setting, {callback:function(data){
    alert("data is saved through DWR");
}});


the error message is
 DEBUG [org.directwebremoting.dwrp.BaseCallMarshaller 43] - Environment:  c0-e6=string:12ssd, c0-e5=Array:[reference:c0-e6], c0-e1=Array:[reference:c0-e2], c0-e2=string:1000, c0-e3=Array:[reference:c0-e4], c0-e4=string:ddd,
INFO [org.directwebremoting.impl.DefaultRemoter 51] - Exec: AjaxUtil.saveSetting()

 DEBUG [com.util.AjaxUtil 24] - save setting:[reference:c0-e2]--[reference:c0-e4]--[reference:c0-e6]

I have defined in the dwr.xml
<convert converter="bean" javascript="Setting" match="com.model.Setting"/>

Do I miss some something ?

Thank.

Send us your dwr.xml and the java method you are calling.

What version of DWR are you using and have you tried removing the
javascript attribute on your converter?

<convert converter="bean" match="com.abs.model.Setting"/>

another weird thing is

var newSetting = {settingId: item.settingId};
doesn't work. I have to manually conver it to a string, like
var newSetting = {settingId: item.settingId+""};

I am using Dojo, it is related to Dojo ?

Thanks,

Try calling the method from the DWR test page please.  You will need to
enable debug mode to do this.

because it is an object, I don't know how to test it in the test page.

it works as expected, because it is a String.

But "var newSetting = {settingId: item.settingId}" in javascript, it will not work.

Regardless, the JavaScript object created is passed to the server as a
string and DWR parses and serializes that string into your Java object
(whether it is a string on the test page or a JavaScript object).

I am not sure exactly what is going on in your JavaScript but if you
build a JavaScript object that looks exactly like what you passed in on
the test page:
var newSetting = {prop1: "prop1val", etc., etc.};

everything will work, I can assure you.

I recommend using Firebug and inspecting the JavaScript object you are
passing to your remote method.  Something is not right with the way you
are building the JavaScript object.
