No, because I just figured the obfuscated code wasn't worth trying to
deobfuscate, but apparently symbolMaps is the key.  Kirill provded the
details so I plan to refer to that.  Thanks for the time!

This sounds like exactly what I need.  Not to take more of your time, but

Thanks for the response, and yes, totally inaccessible by any means.

So back to my main question: are there any serious ramifications, mostly
related to runtime (as I understand the issues with loading), with running
a non-obfuscated application?

Thanks!

Hi Vassillis-

Thanks for the response.  A few comments:

> the problem is reproducible in the remote system and not just happens
after several hours of usage

It's not entirely reproducible, but does seem to happen with some
regularity.  And yes, it has hours of usage, which could be the problem.

> it is a client side error and not a server side error

Definitely client side.

But the rest of what you say I don't completely understand.  Yes, it is
running https, but I should have been clear, I also don't have access to
the server.  I don't have access to anything as it is all on a remote
private network.

Sorry for the confusion.

Re: GWT and async requests (startAsync)

2016-12-23 Thread Robert J. Carr

Thanks Thomas. I was hoping it'd be easier and I was just missing
something. Moving this call out of rpc is probably the best solution.
Thanks again for the guidance!

Since servlets 3 had been out for a long time now it'd be a great idea to
have the developers write this feature into RemoteServiceServlet.

Re: client logging config help with unexpected popup

2015-01-27 Thread Robert J. Carr

Thanks for the response, but I'm fairly certain I've never started super
dev mode, certainly not on my build server, nor do I see any unexpected
cache folders in my working directory.  I like the idea though, maybe there
is some other cache I can try? I vaguely remember seeing such a thing but I
can't recall where.

  If you want a lower level then you need to use ... in your own module.

Right, as I said, all I have in my config file is this:

inherits name=com.google.gwt.logging.Logging/
set-property name=gwt.logging.enabled value=TRUE/
set-property name=gwt.logging.logLevel value=CONFIG/

Yet I'm still getting the logging popup.  Makes no sense to me.  As I said,
it only happens in linux (specifically RHEL and it happened in both 5 and 7
although I don't see how it matters).  It didn't (and doesn't) happen in
GWT 2.6.1 with the same exact config.

Thanks for any help you can offer!


On Tue, Jan 27, 2015 at 3:41 PM, Jens jens.nehlme...@gmail.com wrote:

 I am not sure if that also applies to GWT 2.7 as I am using GWT trunk but
I had to delete SDM caches to let changes to logging configuration take
effect. When SDM starts it tells you which workDir it uses for compilation.
Next to that workDir SDM also creates a cache directory named
gwt-cache-some hash. Simply delete all these cache folders and also the
workDir itself. Then start SDM again to give it a clean start.

 When you inherit Logging.gwt.xml then GWT will, by default, only log
SEVERE and everything else will be compiled out. If you want a lower level
then you need to use

 set-property name=gwt.logging.enabled value=TRUE/
 set-property name=gwt.logging.logLevel value=INFO/

 in your own module.

Re: help understanding complicated client logs

2015-01-20 Thread Robert J. Carr

Just following up on this.  It turns out the problem was that I have some
native javascript that builds some elements after the page loads and these
elements are referenced in the gwt (that's where the null panel was showing
up).  Even though this panel is referenced in a deferred block the page may
still take longer to load than that and the elements aren't yet created.

I tried fixing this by dynamically loading the gwt nocache file in my
native javascript with something like this:

var gwt = document.createElement(script);
gwt.setAttribute(type, text/javascript);
gwt.setAttribute(src, gwt/gwt.nocache.js);
document.body.appendChild(gwt);

But either the browser or gwt didn't like it (I got various errors that I
couldn't figure out).

So, I ended up creating a timer that keeps checking the availability of
that panel and only proceeds after it's been created.  Seems strange I
can't control when the GWT files get loaded, but this will work as a backup.

Thanks again for the help!

Thanks so much for the detailed response.  And I'll give those dev tool
suggestions a try.

And what you say makes sense about dereferencing a null, but it doesn't
explain how it would work most of the time, but sometimes it doesn't.  If
the code is dereferencing null it should always be an error, right?

Anyway, thanks again, you've given me some things to try.

 You can test it locally if you use Chrome DevTools. When you open DevTools
 you can click on the small mobile device icon on the left side right next
 to the search icon. Once you have done that you should see a new dark
 toolbar at the top of your page which has a Network drop down which allows
 you to emulate slower network conditions in Chrome.

 Given your stack trace it seems like you called
 AbsolutePanel.add(childWidget) somewhere but your instance of AbsolutePanel
 was null.

 For your understanding how to read these stack frames:

 __gwt$exception: skipped: Cannot read property
 'com_google_gwt_user_client_ui_UIObject_element' of null
at
 Unknown.com_google_gwt_user_client_ui_AbsolutePanel_$add__Lcom_google_gwt_user_client_ui_AbsolutePanel_2Lcom_google_gwt_user_client_ui_Widget_2V

 First line is the JavaScript exception message which says you have tried
 to access UIObject.element but UIObject was null. Since UIObject has a
 getElement() method that means your java code did call null.getElement().
 At the next line you see that this happened in
 AbsolutePanel.$add(AbsolutePanel, Widget). This method has been generated
 by the GWT compiler and is a static version of AbsolutePanel.add(Widget).
 These generated static methods are marked with $ by GWT. Given the
 implementation of AbsolutePanel.add(Widget) it seems like your instance of
 AbsolutePanel was null.

 Your code did something like:

 AbsolutePanel myPanel = null; // somehow the variable was null
 myPanel.add(child);

 with AbsolutePanel.add() being implemented as:

 public void add(Widget w) {
super.add(w, *getElement()*);
 }

 GWT compiler changed your method call to a static method call

 AbsolutePanel.$add(myPanel, w);

 And the implementation of $add is probably similar to

 public static void $add(AbsolutePanel instance, Widget w) {
   ComplexPanel.$add(w, *instance.getElement()*);
 }

 The bold code causes the exception. Since getElement() and the element
 field are defined on UiObject the exception message says you have tried to
 access UiObject.element with UiObject being null.

Sorry this has taken a while to respond, but I just tested again with your

Re: Random (and unwanted) PopupPanel in GWT 2.7

2014-12-05 Thread Robert J. Carr

Thanks for the lead, yeah, I am using logging. But I thought I had disabled
it all. Any idea which logging this is? I recall having to disable a logger
or two when upgrading to 2.7.

And why would this only show up on a Linux build?

Thanks again!

However, there's a nightly build that happens on Linux (RHEL) and

there when I start my GWT web app a random PopupPanel appears in the far

Does anybody know what's going on?

Re: Need help with JSNI

2014-03-19 Thread Robert J. Carr

Right, I first followed the static export example and got things working.
 Then realized I actually wanted to use it non-statically and got help on
this forum with how to include the instance into the export (main.@...).

As I said, it would work sporadically, but not always.  An non-static
example would be very useful as I still don't completely understand why it
needed to be wrapped with an anonymous function.

 Indeed. I also always forget about that 'this' thing and I am pretty sure
 I would have written the same code as you did in the first post and would
 have lost some time again until remembering that

 public void log(String level, String msg) {
   logger.debug(msg);
 }

 will try to access logger on $wnd.jsni when calling it from pure JS
 (following your example).

 I think we should add a non-static method export example to
 http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsJSNI.html#callingand 
 explain why such an export looks different.

Re: Trying to export non-static methods to javascript via JSNI

2014-02-15 Thread Robert J. Carr

Thanks for the quick responses.  That makes sense that since the jsni
method is declared static that you can't use this, but I'm not following
Thomas's explanation.  Maybe I could just get an explanation from the docs
example here:

http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsJSNI.html#methods-fields

Under the example: Accessing Java fields from JavaScript

Where it has:

public class JSNIExample {

  String myInstanceField;
  static int myStaticField;

  void instanceFoo(String s) {
// use s
  }

  static void staticFoo(String s) {
// use s
  }

  public native void bar(JSNIExample x, String s) /*-{
// Call instance method instanceFoo() on this

th...@com.google.gwt.examples.JSNIExample::instanceFoo(Ljava/lang/String;)(s);

// Call instance method instanceFoo() on x

x...@com.google.gwt.examples.JSNIExample::instanceFoo(Ljava/lang/String;)(s);

// Call static method staticFoo()
@com.google.gwt.examples.JSNIExample::staticFoo(Ljava/lang/String;)(s);

What's the difference here between using the 'this' and the passed in 'x'?
 What does 'this' represent in this example?

As for Thomas's explanation, are you saying that by calling $entry it
creates a new inner function (or closure) where 'this' is no longer what it
was?  So if I didn't use $entry then 'this' would be what I expect it is?

Thanks again for the help!

Thanks for the explanation and examples.  I actually know javascript quite

 The 'this' is the same here as it would be in Java, difference between
 'this' and 'x' is the same too.



 As for Thomas's explanation, are you saying that by calling $entry it
 creates a new inner function (or closure) where 'this' is no longer what it
 was?  So if I didn't use $entry then 'this' would be what I expect it is?


 It has nothing to do with $entry() but the fact that you export a method
 of an object, and the way things (and specifically 'this') work in
 JavaScript.

 Let's use pure JS:

 function JSExample() { };
 JSExample.prototype.instanceFoo = function(s) {
   // use s
 };
 JSExample.staticFoo = function(s) {
   // use s
 };
 JSExample.prototype.bar = function(x, s) {
   this.instanceFoo(s);
   x.instanceFoo(s);
   JSExample.staticFoo(s);
 };

 We can create a JSExample instance and call bar:

 var y = new JSExample();
 y.bar(new JSExample(), msg);

 Now export the method from 'y' without binding it to the JSExample
 instance and try to call it:

 var foo = y.bar; // could be window.foo instead of var foo; y.bar is the
 same as JSExample.prototype.bar
 foo(new JSExample(), msg); // fails because 'window' (the current
 'this') does not have an 'instanceFoo' property
 foo.call(y, new JSExample(), msg); // works because we explicitly set
 the 'this' to 'y'

 Now export the method, binding it to 'y' (using a closure) and call it:

 var foo = function(x, s) { y.bar(x, s); };
 foo(new JSExample(), msg); // works, because we call 'bar' on 'y'

 Introduce $entry:

 var foo = $entry(function(x, s) { y.bar(x, s); });
 foo(new JSExample(), msg); // works the same

 With ECMAScript 5, you could now use y.bar.bind(y) instead of using a
 closure, and with use strict the default 'this' would be 'null', not
 'window'.

 When I say GWT doesn't free you from knowing JS, I really mean it!

Re: Suggestions for transferring a GWT project to javascript?

Thanks for the gwt-exporter suggestion (it was already on my radar) and

 In case you  missed the recent GWT.create conference. There are plans for
 GWT 3.0 to make the interoparability between JS and GWT much much easier
 and with web-components you can write JS code and then easily use it in
 GWT.

 Basically, we'd like to keep all of the RemoteService,

 Is there any way to divorce the data serialization from the visualization

 Note that we don't have any problem with GWT, it's actually been great in

 that are uncomfortable with java and it's hard to get the level of
 contribution we need to the project in its current state.

 At some point during the serialization process GWT is calling getClass()

 Thats just how getClass() in Java works. I don't think you can change that
 behavior of GWT-RPC.
 If I give you an instance of type Object how would you know that you only
 have to serialize a specific super class of the runtime type of that
 instance? Thats probably only possible by searching for specific
 annotations that contain that information. GWT-RPC does not have such
 annotations.

 A somewhat similar question is:
 https://groups.google.com/d/msg/google-web-toolkit/OxuDRkJGFDE/jQd_V0aYzaYJ

 You can probably do the same here. Make Subtype a shared class with a
 super-source version for GWT. The super-source version would be empty and
 just extend Type. The CustomFieldSerializer for Subtype would now only
 read/write the Type variables during de-/serialization.

Thanks for the response, but I don't *want* Pair to serialize.  And

Re: help with jsni

2010-05-03 Thread Robert J. Carr

Ah ... spoke too soon.  You'll see in the collections examples the
constructors are still protected, i.e., they still need to be created
by the underlying javascript (which is sketchy).

Anyway, it seems if I encapsulate all of the creation and manipulation
of the array it will be transparent, I'm just not sure why this isn't
in the standard library.

 I think my point is, in the example they gave:

 I feel this should be part of the standard library.

Re: Calling the GWT entry module from a servlet

2010-03-09 Thread Robert J. Carr

 Thanks for the response. I however do not understand what you mean by
 sounds like your gwt is using plain-old html, and not a jsp. The
 redirect I am performing is to the host page (initial html page that
 invokes the GWT application). Can this be a jsp instead of a html?

Sure, your gwt doesn't care what it is embedded in, html, jsp, asp, php, etc.

 Also, the difficulty I am encountering with the sendRedirect or
 request dispatcher approach is that once a user has signed out of the
 application, I have a login again link which invokes the same
 AuthenticatorServlet which redirects to the GWT initial html page and
 this redirect fails with a message that the response has already been
 committed. I am essentially looking for some technique to avoid this
 message upon second login from the user.

This error usually means you've written to the output stream before
you send the redirect.  I'm fairly certain if you avoid that you won't
get this error.

Good luck!

Re: Uploading image via RPC to use in TreeItem

2010-02-11 Thread Robert J. Carr

Hi Thomas-

 Basically, you don't want to try and send image bytes through RPC ...
 avoid that and you should be fine.

 could you elaborate on that. please. What's the problem with doing so?

Sure ... it's pretty simple.  AFAIK, there is no way for a browser to
deal with image bytes.  As I said, you basically have 2 options:

 1) Create an Image object and for the URL point to a servlet that
will return image bytes to you.

 2) Call an RPC that will return a String and set that as the source
(setURL()) of your Image.

Good luck!

 They way I have don this now is by passing this to every composite

Re: Deprecated SerializableException

Re: How to insert static HTML content

2009-11-03 Thread Robert J. Carr


Well, what you say here:

GWT is a one page show

Is absolutely true.  Given that, you'll have to come up with the
solution that suits you best.  Some options are:

 1) Don't use GWT for the login and have it redirect you to your GWT
page when you've authenticated.
 2) Integrate your login into GWT and have it replace the login with
content when you've authenticated.
 3) Create 2 GWT apps, one for login and one for content.

There are probably other options I'm missing ...

Re: jsni getting rewritten

2009-06-02 Thread Robert J. Carr


Hi Sumit-

Thanks for the response.  I'm looking forward to hearing from Scott if
he has anything to say.

My example of doing simple arithmetic was only to explain the problem.
 However, if I think about it more, maybe it is still applicable.

Say I have an application that allows users to input arbitrary
(javascript) equations, e.g.:

Math.round(Math.pow(2,z)/2.0))-y-1

(Where x, y, and z are invariable)

Without writing my own lexer, how would I go about trying to find a
result to that?  That's why I figured using eval(), which is a lexer,
is the perfect solution.

Thanks again for the response.

On Tue, Jun 2, 2009 at 11:36 AM, Sumit Chandel sumitchan...@google.com wrote:
 Hi rjcarr,
 Because you can do arbitrary things in an eval, I'm not sure the GWT
 compiler will be able to infer that there are types referenced from the JSNI
 method parameter list in the eval argument. I could be wrong on that, so
 I've cc'ed Scott to double check that assertion.
 On the other hand, you could use regular GWT code to perform calculations.
 The GWT Java code you write will translate into optimized JavaScript anyway,
 so it seems like you could just as well stick with Java code arithmetic and
 rely on it to be cross-compiled into similar JavaScript as the one you're
 using in the eval.
 Hope that helps,

 On Sun, May 31, 2009 at 9:40 AM, rjcarr rjc...@gmail.com wrote:

 For what it is worth, I solved the problem by doing this:

  eval(var y =  + y);
  eval(var z =  + z);
  return parseInt(eval(x + y * z));
 }-*/;

 And it seems to work, but seems there could be a smarter way.  This
 method is called *very* often so it's in my best interest for it to be
 as efficient as possible.

 A bit more explanation, I'm allowing users to define expressions that
 I want to evaluate (think of a calculator).  Rather than writing my
 own lexical analyzer I thought I'd use the one built into javascript.

Re: DeckPanel causes Widget to disappear

2009-03-03 Thread Robert J. Carr


Hi Ian ... thanks for the response.

Let me put it in code then:

Widget w = new MyCompilicatedWidget();

DeckPanel deck = new DeckPanel();
deck.add(w);
deck.showWidget(0);

RootPanel.get(main).add(deck);

// This doesn't work ... shows up as a single black line, however:

Widget w = new MyCompilicatedWidget();
SimplePanel simple = new SimplePanel();
simple.setWidget(w);
RootPanel.get(main).add(s);

// Works fine, or even:

RootPanel.get(main).add(new MyCompilicatedWidget());

// End code

Assuming I have no styles applied to my DeckPanel (which I don't), I
don't see how this can be a CSS issue.  Thanks for the suggestion
though, I'll dig a little deeper.

Also, not surprising, the same behavior happens for a TabPanel, which
makes sense because it uses a DeckPanel.

 The chances are that you need a height:100% somewhere or that you don't have
 an absolute height in the chain back to the body element.
 Without any code, it's not easy to be more specific (for me, anyway)

 I have a complicated widget that I'm trying to add to a DeckPanel.
 When the DeckPanel is rendered the widget is not shown, there's just a
 thin line a pixel or two high of where it is supposed to be.  Other
 widgets added to the deck are displayed fine.

 Taking away the deck the widget displays normally.  I've been using
 gwt for quite a while now and I've never seen this.  There are no
 errors of any sort ... it just isn't shown.

 However, if I add my widget to a SimplePanel it works fine.  My
 temporary solution is to replace the DeckPanel with a SimplePanel and
 use the setWidget() method with a listner, but I'd prefer to use the
 DeckPanel.

 Is there any explanation for this?

Re: DeckPanel causes Widget to disappear

Great suggestion, but unfortunately it didn't help.  The item I add to
the deck is still hidden.

Thanks though.

 Try adding the deck to the rootpanel before you add the widget to it.
 I'm not saying this is definitely it, but as a general rule, I try to build
 up widgets as I nest them, from the outside in, adding them to the DOM as
 soon as possible.
 The reason being that if it is not connected, then 100% of 0 is 0. Hence
 height = 0.
 The deckpanel (last time I looked) sizes the deck innards to 100%. The
 SimplePanel doesn't.

 Hi Ian ... thanks for the response.

 Let me put it in code then:

 Widget w = new MyCompilicatedWidget();

 DeckPanel deck = new DeckPanel();
 deck.add(w);
 deck.showWidget(0);

 RootPanel.get(main).add(deck);

 // This doesn't work ... shows up as a single black line, however:

 Widget w = new MyCompilicatedWidget();
 SimplePanel simple = new SimplePanel();
 simple.setWidget(w);
 RootPanel.get(main).add(s);

 // Works fine, or even:

 RootPanel.get(main).add(new MyCompilicatedWidget());

 // End code

 Assuming I have no styles applied to my DeckPanel (which I don't), I
 don't see how this can be a CSS issue.  Thanks for the suggestion
 though, I'll dig a little deeper.

 Also, not surprising, the same behavior happens for a TabPanel, which
 makes sense because it uses a DeckPanel.

Re: DeckPanel causes Widget to disappear

2009-03-03 Thread Robert J. Carr


Hi Joe-

What API are you looking at?  I only see one DeckPanel.add() method:

void add(Widget w)
Adds the specified widget to the deck.

I've checked both 1.5.2 and 1.5.3.  There's an inherited add() method,
but it still doesn't match your signature.

Are you thinking of TabPanel?

 I think the problem may be that you are not using the deckpanel add
 methods:
 DeckPanel.add(String text, Widget widget, boolean asHTML)

 Can you try that?

Re: module organization

Great, that is mostly what I expected, thanks for the help!

On Mon, Dec 29, 2008 at 3:47 PM, Shawn Pearce s...@google.com wrote:
 There isn't really any effect either way.  The additional module might take
 a tiny bit extra time to compile (like under 1 ms) due to the compiler
 needing to read an extra XML file.  But all of the code from all modules is
 flattened out at compile time into a single JavaScript file.  So there is no
 runtime impact to using multiple modules vs. one module, and there really
 isn't a compile time impact that you can notice as a developer.

 Generally people try to organize code into modules where there is
 reusability.  Then its easier to reuse code from one project in another by
 just inheriting from the necessary modules.  Its GWT's way of managing
 libraries.

Re: GIS Map Tile Viewer in GWT

2008-09-24 Thread Robert J. Carr


Hey Sumit-

Thanks for the response.  Google Maps requires that you are connected
to the internet in order to both download the image tiles as well as
the javascript code.  The environment I will be in won't be connected
to the internet, so I won't be able to download either of these.

I already have the image tiles I'm interested in, so I'm just looking
for a GWT solution that can take these tiles and manipulate them like
Google Maps does.  Again, it can't be the GWT Google Maps widget
because that just wraps the Google Maps javascript.  I'd need a
solution that has essentially rewritten Google Maps but has done it in
GWT.

There are a few pure javascript solutions out there that does this
(OpenLayers is one), but I need it to be in GWT.

I've started this project and I'm pretty far along so if I get it to a
usable state I'll share what I have.

 Hi rjcarr,

 When you say you're planning to use Google Maps in an offline mode (or
 away from the cloud), could you elaborate a little on what you mean
 exactly or how you're planning to use the Maps API? I'm not a policy
 expert, but I think that what you're trying to do is use the Maps
 tiling, but not through the actual Maps API, which would probably
 constitute a breach of the Maps tile data usage policy.

 You can check out the FAQ about this at the link below. It's possible
 I've misinterpreted what you're planning to do with the Maps tiles
 data, in which case just let me know and we could be on our way to a
 solution for your application.

 Hope that helps,

 In looking through the forums I've seen a reference to a sachamaps

 sure of the best algorithm to use for the tiling.

 If you're looking for a map widget, I know of OpenLayers (pure
 JavaScript, but googling for openlayers gwt gave some results at
 sourceforge and codehaus).
