Hello,
in your example you are returning id (a numeric value) as a string ant
this is the origin of the unexpected behavior.
Indeed this works
public final native String _getIdString()/*-{ return ''+this.id; }-*/;
as well as returning a java numeric value:
public final native int _getIdInt()/*-{ return this.id; }-*/;
(see
http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsJSNI.html#passing-javascript
for details)
Anyway, in general, is probably not a good idea to use Long for a numeric
'native' value
because in js you cannot represent a long number (see f.e.
http://stackoverflow.com/questions/17320706/javascript-long-integer).
Hope it helps.
Alberto.

Hi.
I'm trying to convert js native number to GWT Long and send it over
gwt-rpc. But I got very weird results..
public class gwtbugEntryPoint implements EntryPoint {
@Override
public void onModuleLoad() {
String data = {\type\:\upd\, \id\:123};
ServerEvent serverEvent = JsonUtils.ServerEventsafeEval(data);
RootPanel.get().add(new HTML(GWT id=+serverEvent.getId()));
}
}class ServerEvent extends JavaScriptObject {
protected ServerEvent() {
}
public final native String getType()/*-{ return this.type; }-*/;
public final Long getId(){
String idStr = _getId();
GWT.log(idSTr: + idStr);
Long id = new Long(idStr);
GWT.log(id:+id);
return id;}
public final native String _getId()/*-{ return this.id; }-*/;}
console output:
idSTr:123
id:0
Can anyone explain me, how that could happen?
