 Hi,
 What port of service do you suggest to use ? I am a complete newbie and
 please suggest on how to make a proxy.

 currently authentication server runs on 6828. and GWT runs on , so
 please suggest the change here.

You can either:
 - use your webapp within the hosted mode (-Dcatalina.base=... if
you're using GWTShell, -war ... if you're using HostedMode) instead of
a separate Tomat instance
 - use the -noserver mode of hosted mode (GWTShell or HostedMode);
search the docs and the group for how to use it (I'm a bit tired of
repeating it over and over again)
 - use a proxy servlet in the hosted mode to relay requests to your
separate tomcat instance; search the issue tracker for contribution
proxying servlet to find one (code + how to use it)

 Has this feature been changed in 1.6.4? I checked the command line

Re: TextBox allow only numbers (gwt 1.6.4)

2009-06-29 Thread Dominik Erbsland


thanks for the help so far.
I am aware that there is a new handler system - I just can't figure
out a way how to make a TextBox field numbers only.
I tried with a KeyUpHandler and a ValueChangeHandler but could not
find suitable methods to check the input for its validity.
any hints?

Re: Problem specifying Grid's cell size

You can apply border-spacing to a table (e.g. your grid) which adjusts the
spacing between cells. To get rid of it completely, you need to set
border-collapse:collapse to the *table* (not the cells - i.e.not the td
elements)
I think you can get away with setting font-size on the table/grid and to
make the css easier, you might like to set style something like below. It
makes the code easier to read (e.g. every cell has ne. n, nw to indicate
where it is in the grid) and the css is so much simpler - you set all the
widths/heights in one place and therefore don't miss any if you change from
5px to 3px, say.

Grid grid = new Grid(3, 3);
grid.setStylePrimaryName(my-Grid);
CellFormatter f = grid.getCellFormatter();
f.setStyleName(0, 0, my-Grid-ne my-Grid-border-row
my-Grid-border-col);
f.setStyleName(0, 1, my-Grid-n  my-Grid-border-row);
f.setStyleName(0, 1, my-Grid-nw my-Grid-border-row
my-Grid-border-col);
f.setStyleName(1, 0, my-Grid-e  my-Grid-border-col);
.
.
.
and then the css is simpler

.my-Grid
{
font-size   :  1px;
border-collapse :   collapse;
}
.my-Grid-border-row
{
height  :5px;
}
.my-Grid-border-col
{
width   :5px;
}
.my-Grid-ne
{
/* put the north-east corner image here */
}
etc

Re: How to know when a Widget is fully loaded....

2009-06-29 Thread Sean


Hi Adam,

Thanks for all the great ideas. I also think it has to do with images
not being fully loaded. This has been my biggest hurdle with GWT. I
tend to use a lot of images, and rely a lot on image sizes, but they
aren't very reliable because of the fact that the image could be
initialized, without being downloaded yet. I didn't know Load Handlers
existed. That stinks it doesn't work well with IE. I think I do need
to look into using the CSS more with %'s.

Thanks again for all the ideas!

 working a second time around as images are also already cached and

 I can think of two options of the top of my head, there are probably
 more

 a) use LoadHandlers on your Image(s) these will tell you when the

 b) enforce Image size using CSS either directly on the Image, or put
 the Image widget in another container (SimplePanel, for example) and
 set Image to 100% and size of SimplePanel to what you require through
 CSS
 c) do what you're doing with a timer until approach in (a) is fixed in
 gwt

 I wonder though if you can't achieve what you want just by using
 percentages in Style Sheet

 Hope that helps

Re: Newbie question re returning persisted objects via RPC to client

2009-06-29 Thread Will


I took a slightly different approach to option 1.

I created a interfaces that describe the Animal and made both the DTO
and GWT implement the interfaces.  This lets me control the
dependencies and ended up cutting down on the amount data I needed to
send to the browser.  I'm actually referring to a scheduling
application but to keep the Animal analogy I found that the majority
of components only needed to know the animal's species and age, not
every detail that was in the object.

On Jun 29, 12:34 am, Dalla dalla_man...@hotmail.com wrote:
 You would have to do it either like you suggested; create two separate
 classes,
 one persistence class, and then one DTO class.

 Or you could create just a POJO and keep the persistence info in a
 separate mapping file.

 From what I understand, most tend to go with the first option.

Invoke oracle from suggestbox on key

Is it possible, as I can't find a way to do this (adding the handler

http://puntosoft2k.appspot.com/gwt_gae_example.html

The example shows how to create, update, delete and retrieve objects from
app engine datastore to GWT client using RPC. The example use DTO approach.
Source code is available.

Hope that helps.
Regards,
Ale

 Let's say I want to persist Animal objects using JDO and also want to
 return these Animal objects via a GWT RPC service. From what I
 understand GWT will compile a version of Animal in javascript on the
 client. And I take it that any JDO persistence stuff shouldn't be
 going down to the client.

 So do I have to create two separate classes for my Animal type: one
 used on the server for persistence via JDO and another which the
 client uses over RPC. Is this the normal thing to do?

Very large GWT app

2009-06-29 Thread Paul van Hoven


I developped a gwt app over the last 3 months. But i found out that
the compiled js file is too large. In total it has a size of 411KB.
Therefore i thought it would be a good idea of splitting up my
application and create some modules. My goal is to split the whole
application up into parts of about 60K-100K. At least the start page
should load very quickly. I have no experience in using modules in gwt
and the google documentation seems to be very brief on this topic.

What is the best approach for splitting up my application?

ImageBundle createImage does not trigger events as opposed to Image

2009-06-29 Thread abby


Hi,
  I just discovered an interesting issue. In one of my views i have a
bunch of widgets like textbox etc and a Proceed button (which is
basically an image). If i create Proceed using new Image(url) all
events are fired for text boxes etc, but if use
ImageBundle.createImage, and someone modified the textbox content and
directly uses the mouse to click on Proceed, change and blur events
for the textbox are not fired.

Is this a bug or an expected behaviour?

Re: How i execute cmd.exe via GWT

2009-06-29 Thread Damien Picard

Hi,

For security issue, you couldn't launch application from a browser.
If you want to do that, you have to pass through an ActiveX control (IE) or
a chrome app (FF) for example, but there is no portable solution, and it is
probably a bad idea to permit it...

Maybe the best way to dot that is to develop a Java applet which could, with
a correct java.policy, execute local file.

Re: generics, events, dependency injection

  Hi all.

  I've been trying to get a nice setup of the best practices presented
  at google i/o. I have something working, but a few questions.

  The first one is how fine-grained do you go for the events you define?
  Say i have events for updates in entities A and B in my model:
  UpdatedAEvent, UpdatedBEvent. To prevent creating new event classes
  for every entity i might add, i liked the idea of usinggenericsafter
  looking at the source code of GWT.

  Classes like:
  public class ModelUpdatedEventV extends
  GwtEventModelUpdatedHandlerV {
  ...
  private static TypeModelUpdatedHandler? TYPE;
  ...
  public static TypeModelUpdatedHandler? getType() {
    if (TYPE == null) {
      TYPE = new TypeModelUpdatedHandler?();
    }
    return TYPE;}

 I'd rather write:
 @SuppressWarning(unchecked)
 public static V TypeModelUpdatedHandlerV getType() {
    return TYPE;

 }

 (TYPE might have to be of type Type?)

 (Given that you most probably won't use ModelUpdatedEvent without its
 TYPE, you can just initialize it in the declaration, like GWT does,
 and have getType() just return TYPE)

  But then i guess i can't use them with an event bus (the
  HandlerManager)? I lack complete understand ofgenericsand wildcards,
  but assuming the class doesn't know the type, this won't work right?

 Even if the class did use V, it wouldn't work, becausegenericsin
 Java are hardly more than just syntactic sugar (google for 
 javagenericserasure).

  eventBus.addHandler(ModelUpdatedEvent.getType(), ...)

 However you write ModelUpdatedEvent/ModelUpdatedHandler, you'd end up
 having all your handlers receive all ModelUpdatedEvent? events.

 The only way you could make this work is having a getType(Class?
 cls) returning a different TypeModelUpdatedHandler? instance for
 each class given as argument:

 public static V TypeModelUpdatedHandlerV getType(ClassV cls) {
    // do your magic here}

 ...
 eventBus.addHandler(ModelUpdatedEvent.getType(A.class), ...);

 ...or you could instead have a getTypeForA() and getTypeForB()
 methods:
 public static TypeModelUpdatedHandlerA getTypeForA() { return
 TYPE_A; }
 public static TypeModelUpdatedHandlerB getTypeForB() { return
 TYPE_B; }

 ...this wouldn't be that different from having a ModelUpdatedEvent
 subclass per model class.

Thanks for your reply. I've done this (multiple subclasses), but was
looking for a better option.


  The second point is regarding dependency injection. I got it working
  for things implementing interfaces, to which i bind implementations.
  But how do you go for the HandlerManager for example? I've tried
  making it a singleton as in:
      protected void configure() {
          ...
          bind(HandlerManager.class).asEagerSingleton();
          ...

  but i get No @Inject or default constructor found for class
  com.google.gwt.event.shared.HandlerManager.

  Same if i use .in(Singleton.class). I've seen that GWT should fallback
  to GWT.create when there's no injection available, but if i don't
  mention the HandlerManager in my injector it also fails.

 ...and GWT.create() expects a default constructor.

 The solution IMO is to use a provider.

Provider it was (as in provider method), it worked fine.

Thanks again,
Ricardo

Re: Why does HorizontalPanel cells defaults to vertical-align: top?

2009-06-29 Thread Joseph Arceneaux

This placement within a panel is very confusing.  I am trying to stack some
labels contiguously in a vertical panel, starting at the top.  But the panel
places the first label at the very top, and then the second label in the
very middle.  I've tried changing the CSS style, and also various
permutations of the following Java:
panel.setVerticalAlignment (HasVerticalAlignment.ALIGN_TOP);
panel.add (label_1);
panel.setCellVerticalAlignment (label_1,
HasVerticalAlignment.ALIGN_TOP);
panel.add (label_2);
panel.setCellVerticalAlignment (offset,
HasVerticalAlignment.ALIGN_TOP);

but nothing seems to change this behavior.

Any suggestions?

Thanks,

  Why is that so? Am I missing something or is there no way to align

Re: Convert a Java Swing Application

2009-06-29 Thread DaBlick


I would suggest that you consider using the Ext-GWT component library
instead of the native GWT components.   Ext-GWT (also known as GXT)
provide a far more Swing-like approach (MVC, etc.) to GUI's than GWT
components.

I definitely believe it's a shorter leap from Swing to Ext-GWT than
to GWT.

On Jun 26, 2:13 am, romant roman.te...@gmail.com wrote:
  can I use Google Web Toolkit to convert a Java Swing Application?

 It depends on the complexity and functionality of your Swing
 application, but generally I would say yes, you can. Of course you
 must take into account that the set of components which GWT offers is
 different than the set which is available in Swing. So your Swing
 application will have to be adjusted a bit. But if you use some
 component library for GWT this limitation can almost disappear.

  Has already anybody convert an application?

 Yes, I converted a Swing application which provided some accounting
 functionality. Firstly you should consider what functionality your
 Swing application provides and how to move it (if it is even possible)
 to the web environment. Then the user interface will have to be
 probably adjusted a bit so that it can be implemented using the
 available GWT components, but this is not such a big problem.

  Can anybody give me some information?

 You've just got some.

Re: Very large GWT app

2009-06-29 Thread Paul van Hoven


It is definetly the size of one single XYZ.cache.hml file. If i cannot
split up this cache file even when using separate modules this means
that the user has to download initially 412K? Because then the user
had to wait quite long before he could see anything and in turn had to
download parts of the application which he would probably not going to
use.

And with GWT 2.0 i could split up the app? After googling for runasync
i found that this function seems to do exactly what i want. Is it
already recommendable to use GWT 2.0 in this early stadium of
development?

any hints how I can check the input with the KeyUpHandler of gwt

Given that Google uses it for publicly accessible services (Google

all depends on your release schedule.
For instance, if I were starting an app to be released after the

Re: GEP rebuild deletes war/WEB-INF/classes

2009-06-29 Thread Jeremy Cohen


Thanks for the tip Thomas, I'll check it out.

The downside of this is that I now need to update my ant build file
that was created using webAppCreator to manually copy these resources
prior to running ant hosted or ant war. I agree that while the GWT
1.6 project structure is a huge improvement, the use of the war/WEB-
INF/classes directory in the source directory path doubling up as the
default compile output path is a little unclean.

A flow panel doesn't work insofar as the textbox is not horizontally

Re: onModuleLoad is sometimes not called (Internet Explorer)

2009-06-29 Thread Joel Friedman


In case this helps others, for us it turned out to be a problem with
compression and IE6.  We turned off compression for IE6 user-agents
and the problem went away.

On May 21, 5:55 pm, Joel Friedman joel.fried...@gmail.com wrote:
 I am also experiencing a very similar problem, though with a few
 differences.  It consistently occurs with users behind a corporate
 firewall using IE6 on the first page load when IE has an empty cache.
 Refreshing the page works and as long as the cache isn't cleared, all
 subsequent page loads work.  I have been unable to duplicate the
 problem in a development environment setting up test proxies and
 firewalls so I amnotsure what it is about the environment, but it
 has occured at multiple companies.   I am unable to try IE7 or any
 other browser at those companies so I amnotsure if this strictly an
 IE6 issue ornot.  I verifed from the server logs that all the right
 files are being fetched and did a similar trick to what Steve
 described to verify that onModuleLoad() isnotbeingcalled.  If I add
 some javascript to reload the page when it detects that onModuleLoad()
 hasnotbeencalled, then it works but that feels too hacky for
 production.  Other than upgrading to 1.6 (I am also on 1.5.3), any
 suggestions?  Thanks.

  Steve,
  I can't seem to reproduce the problem on my end, but for what it's worth,
  latching with a timeout like that is going to be pretty brittle in practice.
  Here's an alternative formulation that won't be flaky:

  HTML:

    script

    function onGwtAppLoaded() {

      alert(w00t!);

    }

    /script

  Java:

    public void onModuleLoad() {

      setLoaded();

    }

    public native void setLoaded() /*-{

      if ($wnd.onGwtAppLoaded) {

        $wnd.onGwtAppLoaded();

      }

    }-*/;

  This works because the GWT linkers all make the guarantee that
  onModuleLoad() willnotbecalleduntil the DOM is ready (i.e. all the DOM
  elements, including the body, are fully-evaluated, including scripts). So
  there's no chance that onGwtAppLoaded() will *not* be defined when
  onModuleLoad() iscalled.

  Hope this helps,
  joel.

   Intermitently using Internet Explorer, it simply fails to call the

Re: GWT architecture MVP/EventBus (mentioned at Google I/O)

2009-06-29 Thread Daniel Jue


Does anyone have a working MVP/Eventbus sample of something simple
like the PhoneEditor?
I don't think I'm doing it right.  The code from the IO presentation
leaves out enough details so that I'm not sure what to do.
For instance, in my Presenter.class,

I have something like this:
public class Presenter {
...
private Display display;
interface Display {
HasClickHandlers getSaveButton();
HasClickHandlers getCancelButton();
HasClickHandlers getNumberField();
HasClickHandlers getLabelPicker();
}
void editPhone(Phone phone) {
this.phone = Phone.from(phone);
display.getNumberField().setValue(phone.getNumber());
display.getLabelPicker().setValue(phone.getLabel());
}
...
}
Obviously, a HasClickHandlers object doesn't have a setValue method.
It doesn't feel like I should be casting to the widget here, since we
went through all the trouble of using the Display interface.


I started looking at Mvp4g, but it seems to go off on a tangent with a
code generation class to wire up presenters and views via xml.
http://code.google.com/p/mvp4g/
It's also intertwined with some mvc4g classes.

I just want something basic that works, so I can seed my project from
there.  A minimalist, working command style RPC example would be nice
too.
Anyone?  If you're in the DC area, I'll buy you a drink!

GWT components too big in IE


Hi,

GWT seems to render components too big in IE. This can be seen simply
by navigating to the GWT showcase. Make sure the zoom is reset (100%).

It is obvious this is a GWT thing as evidenced by looking at Google
docs. The components in docs are fine.

Is this a bug? (a feature??)

Re: GWT architecture MVP/EventBus (mentioned at Google I/O)

2009-06-29 Thread mabogie


check this out:

http://www.webspin.be/

I left out the model (Phone class here) and the command pattern, since
I'm not using it yet.

For your comment on the casting: I'm having trouble with that too.
When I want to attach the widgets to the root panel or whatever other
panel, I can't do anything but cast them. But nobody seems to have a
good solution...

 I don't think I'm doing it right.  The code from the IO presentation
 leaves out enough details so that I'm not sure what to do.
 For instance, in my Presenter.class,

 I have something like this:
 public class Presenter {
 ...
 private Display display;
         interface Display {
                 HasClickHandlers getSaveButton();
                 HasClickHandlers getCancelButton();

                 HasClickHandlers getLabelPicker();
         }
         void editPhone(Phone phone) {

                 display.getNumberField().setValue(phone.getNumber());
                 display.getLabelPicker().setValue(phone.getLabel());
         }
 ...}

 Obviously, a HasClickHandlers object doesn't have a setValue method.
 It doesn't feel like I should be casting to the widget here, since we
 went through all the trouble of using the Display interface.

 I started looking at Mvp4g, but it seems to go off on a tangent with a
 code generation class to wire up presenters and views via 
 xml.http://code.google.com/p/mvp4g/
 It's also intertwined with some mvc4g classes.

 I just want something basic that works, so I can seed my project from
 there.  A minimalist, working command style RPC example would be nice
 too.
 Anyone?  If you're in the DC area, I'll buy you a drink!

Re: Why does HorizontalPanel cells defaults to vertical-align: top?

It does if you apply it to the right element. Or at least, I can get it to
work in my test app, though I haven't tried it in browsers generally.
But, more important, what is the effect you are trying to get?

Is the image smaller than the text box or the other way around? Do you want
the bottom of the image and the bottom of the textbox to be in line (this is
what I am understanding from what you have said).

Why is that so? Am I missing something or is there no way to align

Something like that. In effect, what I want is a lot like the search
line in google docs:
logo + textbox + button

I have tried various combinations, including putting the textbox 
button in their own horizontal panel. The reason I did this is because
the button is taller than the textbox on IE. (In fact, on IE every
component seems too big). I have this latter horizontal panel bottom-
aligned, and the widget themselves middle-aligned. The overall effect
is like this:

|image|
|image|  |textbox(slightly above baseline)|  |button (bottom on
baseline and top slightly above textbox's top)|

(Hoping I'm being clear...)

Anyway, I lost a good 10 hours on this problem so far. True I'm new to
all this, but it's a lot. I feel at this point it's more than enough
time spent on a single (simple?) problem. Sure, I wanted to be a good
boy and keep the code and presentation separated. However, I think
I'll keep the setHorizontalAlignments in the code because it's the
only thing that works.

Unless you have a better idea... to which I'm very open, I want to
learn.

Hi all,

 updated when the user calls makePersistent on it.
 I think this is sufficent, because:

 a) It's not practical to track changes on the client (for example, JSNI
 methods could easily bypass any mechanism we put in place), and
 b) AppEngine doesn't do partial updates
 anyway, so there's no performance advantage in that environment for trying
 to do more.

 By the way, the design is largely based on one of the emails you sent to the

  To make Google App Engine and GWT work together (in adapter4appengine

  My first goal was to add *clean extension points*, to allow any third

  Hibernate one as well.

  The idea is to allow 2 kinds of extension points :
      - ISerializationFilter, that indicates if a specific field of a
  class should be serialized or not. It is called for serialization
  signature computation and for each object serialization
          * Typical use : used to remove new fields from enhancement
      - ISerializationTransformer, that can change a object instance
  from one type to another one
          * Typical use : used to turn persistent collection back to
  regular one

 Are you familiar with the transient keyword and the @GwtTransient
 annotation?  These let you respectively eliminate a field from
 serialization, and eliminate a field from GWT serialization.

2009-06-29 Thread Joel Webber

That's fairly closely related to the approach I'm taking. It is worth
noting, however, that this totally fails on IE6, because it won't handle the
kinds of implicit constraints created by, e.g., { left:0; right:0; }. Just
to make matters more difficult, it also can't handle { right:0; }
properly (often off-by-one pixel). Part of the work I'm doing involves a lot
of script hackery to account for this, without hamstringing the
implementation on other browsers.

[gwt-contrib] Re: SoyLite

2009-06-29 Thread Katharina Probst

I think this is a great idea, especially because it can be offered side by
side with the existing SOYC (that includes partial blame assignment).  I
agree with you, Lex, that explaining partial blame assignment has been a
challenge.  What I am still trying to understand is exactly how blame is
assigned under SOYLite.  I'm not familiar enough with the symbol maps, but
what does happen when something gets inlined?

kathrin

On Fri, Jun 26, 2009 at 3:20 PM, Lex Spoon sp...@google.com wrote:

 I've been trying to think of ways to speed up the -soyc option, and
 here is the result of one attempt.  What do people think?

 The idea is to mimick some aspects of the speedy symbolMaps files.
 Instead of using the enhanced SourceInfo's to track links between
 before-optimization and after-optimization code, bill size information
 only to the program as it stands at the end of Java optimization.
 Additionally, be careful to avoid needing any massaging of the data
 in StoryRecorder; instead, make a single pass through all
 the size information.

 This means that the size breakdown will no longer have fractional
 sizes, and individual output bytes will no longer be fractionally
 billed to different chunks of source code.  The main question is, can
 we live with that level of output?

 I have found in practice that people don't understand the fractional
 billing. They ask why their methods have fractional sizes, and I
 end up giving them a monolog about inlining until their eyes glaze
 over.  It seems that you need to understand the inlining effects
 before you can understand what the current report gives you;
 however, if you understand the inlining effects, it seems to me that
 you can make good use of a report that doesn't use fractional billing.

 Additionally, it adds more pending work if SOYC continues to show both
 before-optimization breakdowns and after-optimization dependency
 information.  To make a long story short, there are at least two
 substantial work items related to this discrepency, and it would
 remove that work if SOYC switched over to only reporting on the
 program as it exists after Java optimization.

 Of course, we have to be happy with the new size breakdown.  What do
 people think--is the fractional billing important enough to pay the
 extra compile time?  Here are two example SOYC reports using each
 method.  The lite version drops fractional billing, so you'll see that
 the sizes all end in .0.

 http://www.lexspoon.org/soyc1821/trunk/SoycDashboard-index.html
 http://www.lexspoon.org/soyc1821/lite/SoycDashboard-index.html

 In the lite version, please ignore all parts of a breakdown except the
 package breakdown in the top-left pane.  I wanted to share the idea
 around before I finished implementing a lite version of the other
 three panes.

 If the lite version looks fine, we will get some great timing
 improvements.  To show this, I tried compiling one-permutation
 Showcase in four ways: both with and without -soyc, and both with and
 without the patch.  For each way of compiling, I compiled it four
 times, but I discarded all the first results to try and reduce caching
 effects.

 With the patch, the timings are as follows.  The main number is the
 average, with the individual timings in parentheses.

  regular compile:  36.5 (36.1, 35.9, 32.1)
  with -soyc: 34.0 (33.9, 32.7, 35.5)

 By these numbers, using -soyc is faster than a regular build!  I don't
 know whether I introduce some overhead in a regular build, or if it's
 just noise in the measurements.  Either way, it looks good for the
 speed of -soyc with the patch in.

 To compare, here are the numbers without the patch:

  regular compile: 34.0 (35.8, 34.0, 32.1)
  with -soyc: 39.6 (40.2, 39.6, 39.0)


 The regular compile time is exactly the same as the -soyc time after
 the patch.  As is already known, however, using -soyc without the
 patch adds a lot of time, 16% by these measurements.  Based on
 PerfLogger, the StoryRecorder alone takes about 2.5-3 seconds, whereas
 with the patch it takes less than half a second.

 Thoughts?  A rough patch is attached, if anyone wants to play with it
 themselves, but there's more to do if we want to go this way.

[gwt-contrib] Issue 2749: RichTextArea timing issue using BasicFormatter and ExtendedFormatter methods

2009-06-29 Thread jlabanca


Reviewers: jgw,

Description:
Description:
===
Using almost any method in the Basic or Extended formatter when the
RichTextArea is detached results in a JS exception on all browsers.
Even after it is attached, a JS exception occurs in some browsers if the
area is not initialized or if it is *hidden*.  The formatters were
originally designed to work based on user interaction.

Fix:

We now assert that the RichTextArea is ready (attached and initialized)
before performing any actions.  We also wrap commands in a try/catch
block to catch errors associated with a *hidden* RichTextArea.

Since errors vary across browsers, I added some JavaDoc explaining that
the formatters should only be used if the RichTextArea is attached,
visible, and has been focused at least once.  Essentially, this means
that the user is or was interacting with it.


Testing:
===
I manually tested the change on all browsers and added some unit tests
to catch some of the error states.

   This thread follows this one (http://groups.google.com/group/Google-

   before this one.
 
   To make Google App Engine and GWT work together (in adapter4appengine
   project), I had to modify theRPCserialization code.
   My first goal was to add *clean extension points*, to allow any third
   library developer to tuneRPCserialization according to his needs. Of
   course, I used it to develop a DataNucleus adapter, and plan to port
   Hibernate one as well.
 
   The idea is to allow 2 kinds of extension points :
   - ISerializationFilter, that indicates if a specific field of a
   class should be serialized or not. It is called for serialization
   signature computation and for each object serialization
   * Typical use : used to remove new fields from enhancement
   - ISerializationTransformer, that can change a object instance
   from one type to another one
   * Typical use : used to turn persistent collection back to
   regular one
 
  Are you familiar with the transient keyword and the @GwtTransient
  annotation?  These let you respectively eliminate a field from
  serialization, and eliminate a field from GWT serialization.

[gwt-contrib] Manifest for SOYC permutations

2009-06-29 Thread kprobst


Reviewers: Lex,

Description:
This patch creates a manifest file for each compilation permutation if
the compilation is SOYC enabled.  The manifest files are stored
alongside other SOYC manifests (in the soycReport directory).

Each manifest file contains all non-gwt properties for the
permutation, i.e., user agent, locale, etc.

[gwt-contrib] Issue 1441: RichTextArea no cursor until you type in Firefox

2009-06-29 Thread jlabanca


Reviewers: jgw,

Description:
Description:
===
In Firefox, the text caret always appears at the begining of the
RichTextArea when the user clicks the first time, regardless of where in
the RichTextArea the user clicked.

The problem is that we set design mode on focus in Mozilla, which occurs
after the caret is moved.  As a result, the caret isn't set because the
RichTextArea isn't editable yet.


Fix:
===
We now switch to design mode onfocus or onmouseover.  By switching
onmouseover, we can ensure that we are in design mode before the user
selects a caret position.  We still need the onfocus because the user
might tab into the RichTextArea, in which case its perfectly acceptable
to default to the 0th position in the text.


Testing:

Manually verified this fix on FF1.5, FF2.0, and FF3.0.

 I've been trying to think of ways to speed up the -soyc option, and
 here is the result of one attempt.  What do people think?

 The idea is to mimick some aspects of the speedy symbolMaps files.
 Instead of using the enhanced SourceInfo's to track links between
 before-optimization and after-optimization code, bill size information
 only to the program as it stands at the end of Java optimization.
 Additionally, be careful to avoid needing any massaging of the data
 in StoryRecorder; instead, make a single pass through all
 the size information.

 How much would it be skewed by JS-level optimizations?  What about JSNI
 code?

The basic framework is the same in both cases.  Output bytes get
billed back to Java code.  That's final output bytes, after all
optimization is complete.  Both would bill JSNI code to the associated
Java native method.  The difference is whether to map each byte to
multiple methods, or to pick just one.

Let me give some examples.  Suppose Point is a class with a method
getX() that is always inlined.  Thus, Point.getX() is inlined away
during Java optimization.  Then suppose some method TextArea.getArea()
calls Point.getX().

In trunk, Point.getX() is billed for every place it gets inlined, so
it will show up in the size breakdown.  TextArea.getArea(), meanwhile,
will not be billed for all of its output bytes; the ones that it got
by inlining Point.getX() will be partially billed back to
Point.getX().  To contrast, with SoyLite, Point.getX() would not show
up in the size output, and TextArea.getArea() would be billed slightly
more.

As another example, suppose Java method Integer.toString ends up
compiling to JavaScript function toString_3.  Also, suppose the
compiler creates a static version Integer.toString$, which then
compiles to function toString_4.  In trunk, Integer.toString is given
full blame for toString_3 and half blame for toString_4;
Integer.toString$ is given half blame for toString_4.  With SoyLite,
Integer.toString is given full blame for toString_3, and
Integer.toString$ is given full blame for toString_4.

Does that clear things up better?  If not, perhaps we should examine
Showaces in more detail to find real examples of differences to look
at.

[gwt-contrib] gen2 PagingScrollTable: programmatic cell editing

2009-06-29 Thread jay


Another piece of feedback on the incubator paging scroll table...

I've got a case where I need to programmatically change the value in
some cells (based on other input from the user).

However, since the method used as the cell editor's callback is an
anonymous, inline inner class, I have to replicate that code. (I'm
referring to the inner class which starts on line 882 of SVN rev 1640
of PagingScrollTable.)

Perhaps the contents of the callback's onComplete() implementation
could be pulled out to a protected method, available for subclasses to
use?


Thanks!!!

[gwt-contrib] Re: Add Impl.getNameOf() to expose JNameOf nodes to Java code

LGTM, with comment.

Line 95: // Proper JSNI ref
Shouldn't most of this lookup logic be duplicated elsewhere for
resolving jsni refs in general?  IOW, we should factor out a static
method if necessary and share code.

[gwt-contrib] Update RichTextAreaImplSafari

2009-06-29 Thread jlabanca


Reviewers: jgw,

Description:
Most of RichTextAreaImplSafari was written to support older versions of
Safari, which we know longer need to support.  I've stripped away all of
the old stuff, leaving only a few Safari specific implementations.

This patch also fixes issue 2813 by removing some weird text selection
code, which presumably was needed in Safari 2 or earlier.

Testing:
===
Manually verified that this works on Safari and all other browsers.

Please review this at http://gwt-code-reviews.appspot.com/49802
