Re: GWT2.8 JsInterop Java->JS

I tried that, it gave me the same result, but your post gave me an idea. I set printObj up to assign a variable with it's data, so the last element in the list would get it.

Inside
ns.printObj = function(data) {
   ns.foo = data;
}

Then I typed ns.foo into chrome's dev console so I could introspect the object that way. It turns out that the data is there, but it's all mangled with funny symbols like
kRg_g$ {  mySymbol_1_g$  } etc. Can anyone on the GWT team weigh in and tell me how to unmangle it, such that I can write my views in JS and my model/controller in java?

On a side note, it would be really nice if there was a nice no-brainer way of serializing/deserializing between JSON and Java Objects exposed to gwt users. This has always been a huge feature hole in gwt imo.

Thanks
Alex

the object has properties but when you concatenate a string with your object in the line

"We can't see the obj's properties, only:" + obj  

you are essentially converting obj to a string through obj.toString() so your 

native method does not receives the object obj but a string.

try this passing just obj to printObj.

Wouldn't the object have a bunch of JSON properties then?

Hi,
you are converting obj to a string before calling printObj:  "We can't see the obj's properties, only:" + obj 

Hope this helps.

We are usingJSInterop in GWT2.8. In one of our RPCs we have some code like this that passes our java object to JS:
onSuccess(List<MyObject> objs) { 
   for (MyObject obj: objs) {
     jsCode.printObj("We can't see the obj's properties, only:" + obj);
  }
}
The definition of jsCode looks like this:
ns.printObj = function(obj) {
   console.log(JSON.stringify(obj));
}
In the console we get back:
We can't see the obj's properties, only:our.ns.type.MyObject@16

The value object has been annotated as @JsType. Anything else we need to do?
