Since it took me 3 hours to figure out why this doesn't work and I
could not find any other post on the subject, here is one way to do a
deep copy of a JavaScriptObject using JSNI.
public static final native JavaScriptObject deepCopy(JavaScriptObject
obj) /*-{
if (Object.prototype.toString.call(obj) === '[object Array]') {
var out = [], i = 0, len = obj.length;
for ( ; i < len; i++ ) {
out[i] = arguments.callee(obj[i]);
}
return out;
}
if (typeof obj === 'object') {
var out = {}, i;
for ( i in obj ) {
if (i != "__gwt_ObjectId") {
out[i] = arguments.callee(obj[i]);
}
}
return out;
}
return obj;
}-*/;
