Re: MVP with GWT 2.0/UiBinder could be simplified

[mahjong]

Thanks for the reply but some clarification seems to be needed here.
First of all I am not against the current MVP "best practice" at all
(I used it all the time with GWT 1.x). What my post concerned is
really these:
(1) most frameworks inspired by the Ray Ryan talk were pre-dated GWT
2.0 where UiBinder came to life
(2) with UiBinder in hand, whether and how (if it makes sense) to make
MVP even more straight forward

My argument is that, with UiBinder approach, MyView.ui.xml is pretty
much doing the view while MyView.java is already doing only event-
related processing, with none or minimal UI stuff. I wonder if
anything could be done to further clean up MyView.java (which usually
extends Composite type of container and also handles UI-level events).
Without using a 3rd party framework like gwt-presenter, GWT itself
does NOT enforce an MVP practice. But I think that GWT can go a step
forward to combine a lightweight presenter framework, which works best
with UiBinder.

At least at this point I haven't seen a Google paper/web page
discussing the "best practice" of doing MVP wiith UiBinder - take a
look at the end of this page here -
http://code.google.com/webtoolkit/doc/latest/tutorial/mvp-architecture.html,
Google DOES mention it wants to further elaborate on MVP+UiBinder. But
probably it hasn't had the chance to summarize it? Or thoughts still
have to be developed/speculated at this point?

I hope to make myself clear here that when using a gwt-presenter type
of framework along with UiBinder, we are dealing with two injection
systems, one from Gin and one from UiBinder. Not that we cannot handle
this, but wouldn't it be simpler to combine them? or at least to have
a "best practice" to use them simultaneously? I would like to hear if
anyone has had any experience to share, before Google's "guideline"
comes out.

There is no point of arguing the usefulness of presenter - I use it
heavily. To even simplify my question, how do you inject/create a
presenter, in the UiBinder context? I have ways of doing it but I
would like to find out an elegant way.

Thoughts?

Re: upgrade gwt 1.5 to 1.6 help!!

[Gal Dolber]

I recommend you to go straight to GWT 2.0. Just update the SDK and find the
deprecated's in your code.
The biggest problem you can have is with the ImageBundle, now you have to
use ClientBundle.
Also I don't remember if the Listeners -> Handlers transition was before of
after 1.6 ...
Anyway... you won't regret it

Re: Hiding server-side code from the client?

[Gal Dolber]

I am 99% sure that if you don't use the method on the client the GWT
compiler will erase it. Regards

NumberFormat problems(8 decimal places)

[Tercio]

Hi!

I have a NumberFormat with 8 decimal places, that the code:

NumberFormat format = NumberFormat.getFormat("#,##0.");
System.out.println(format.format(1234.5678d));

When I run, it prints: "1,234.7852517"

But should print: "1,234.5678"

If I reduce the zeros to 6, it works("1,234.567800")

Is this a bug or I'm doing something wrong?

Thanks.

verttical scroll panel jumping around in 2.0

[Calin M]

Hi,

I have an application with a vertical split panel. Inside the left
pane I have a tree and its leafs are links. Sometimes the links are
too long and a horizontal scrollbar is created.

Since I upgraded to 2.0, whenever I click on a link, the horizontal
scrollbar repositions itself such that the right side of my link is
visible. This did not happen before and it's anoying to have the
scrollbar jump when you click on it. Is there anything I can do?

Thank you,

Calin

Dude, but after all, SmartGWT so far is the best among others, despite
its somewhat tragifunky API. Yes, for us, who are doing Swing as well,
SmartGWT is quite painful, although it intended to be like Swing for
Web. Yes, method names are wicked, composing widgets is weird etc. And
there is also a number of reasons why they're done this way — hence
let's don't regard them as fools — the guys, actually doing awesome
job. Because what else on the market is available right now that could
solve a huge number of a problems that we facing every day, making
enterprise software for the Web?

Personally I don't like concentrating on JavaScript horror and prefer
Java Swing over JNLP in most cases. In Enterprise controlled internal
network we never allow web stuff — there is only Swing and it works
rock stable. But it requires very clean and highly controlled
networks. Since outside the company, in the wild world, there are
anything you might expect, so browsers + JavaScript + HTML is the only
way. However, it is horrific way to make UIs, has no real standards,
is very unpredictable, slippery and unreliable.

So let's better think how we can help them instead, because everyone
can bashing things: that's no brainer...

Re: GWT 2.0.1 out but Eclipse says "There is nothing to update"

[Sky]

Go to Help -> Install new software...
then choose "Google Plugin - http://dl.google.com/eclipse/plugin/3.5";
from the drop down or else add it if it isn't already there. It should
show both the App Engine and GWT under SDKs.

Check SDKs and click Next.

I had the same thing as you, but this way worked for me.
Hope this helps.

GWT 2.0.1 out but Eclipse says "There is nothing to update"

[Jaroslav Záruba]

I"ve just noticed GWT 2.0.1 has been released, so I wanted to check
how does "my" bug do in the new release, but Eclipse says there's
nothing to update from the update site.

When I browse available software from Google within "Available
Software" the new version is actually listed (also when I check "Hide
items that are already installed").

Am I the only one experiencing this? Am I missing something?

Regards
  J. Záruba

Re: Maven users survey

[Andrew Hughes]

Any improvements in GWT-Maven support from Google would be excellent! Google
are 'maven friendly' :) THANKS KEITH AND OTHERS!

I can't speak highly enough of Maven. It's an instant injection of mature
engineering practices for projects and companies alike.  It's a shame it has
becoming increasingly difficult to work with GWT (2.0) in this (widely
accepted) lifecycle manager / project config.

If I was to give Google an example of what "they're missing" (not just for
GWT) I'd ask them to please have a look at this:
http://appfuse.org/display/APF/Home


Cheers and looking forward to future :)

p.s. thanks again Keith :)

Re: GWT 2 - Different behavior when using DevMode/draftCompile then in Production mode

[Steve Lancey]

Just one more piece of information:

After removing the final and assigning the variable to itself we got
the same behavior in DevMode and Production Mode
String uniqueId = DOM.createUniqueId();
uniqueId = uniqueId;

It seems that the problem lies with the optimizer.

Anyone else faced similar issues?

Deprecation warning

[cretz]

I have a class w/ a couple of static JSNI methods referencing itself.
I deprecated the class, but when the GWT compiler comes across my
static JSNI method in the deprecated class, it shoots out a warning
saying I am referencing a deprecated class like so:

  [WARN] Warnings in 'file:/C:/dir/src/package/ClassFile.java'
 [WARN] Line 42: Referencing deprecated class
'package.ClassFile'

This should be consistent with Java and not give a deprecation warning
if it's referencing itself. This can be worked around w/ a
@SuppressWarnings("deprecation"), but Eclipse doesn't like that. Only
workaround for now is to add @Deprecated to the JSNI methods. This
prolly isn't worth a bug entry, just posting here for anyone else
needing to know.

Exceptions in Event Handlers(inner classes) are not shown by Dev Mode Panel in Eclipse!

[J-Pro]

Good afternoon, dear GWT group members!

I've noticed that if I create an event handler, for example

ButtonItem btnSubmit = new ButtonItem();
btnSubmit.addClickHandler(new
com.smartgwt.client.widgets.form.fields.events.ClickHandler()
{
@Override
public void
onClick(com.smartgwt.client.widgets.form.fields.events.ClickEvent
event)
{
  int i = 5/0;
}
});

I can't see the problem in the Development Mode Panel in the Eclipse.
The last record there is "Module has been loaded". The application
itself behaves just as if nothing happened. You can try it by
yourself.

But if only I put "int i = 5/0;" after ButtonItem declaration, i.e.
not in inner class, the exception will be described in Development
Mode Panel.

Having this, it's very hard to catch errors... Can you advise anything
to me? Or is it a bug?


I use Eclipse 3.5 SR1, Google Plugin 1.2.0, GWT Toolkit SDK 2.0.1,
smartgwt 2.0, latest Firefox and Windows 7 x64 Ultimate.

Thank you very much in advance!

Testing Methodologies Using Google Web Toolkit

[Sesha]

Hi,

Am new to GWT/MVP and was going through the tutorials. I was trying to
get hold of the source code illustrated in the tutorial at
http://code.google.com/webtoolkit/articles/testing_methodologies_using_gwt.html
by Sumit Chandel.

Where can I get hold of the source code for the same?

Thanks,

Hiding server-side code from the client?

[Axel Rauschmayer]

Use case: a data object has some methods that only the server needs.

I'm currently using my own tool to create patched versions of a class
with server-only code. It removes methods annotated with @GwtIgnore
and places the result so that it overrides the server version whenever
GWT is involved.

Is this the best way of solving this problem?

Maybe inheritance can be used (adding the additional methods to a
server-only subclass), but that does not solve this issue if an
inheritance chain is involved and several members of that chain have
server-only code.

Source code availability to the GWT Compiler

[Micah]

I currently have a GWT app that I'm looking to break into separate
modules.  The build system is currently Maven2 and utilizing the gwt-
maven-plugin[1].  When reading over the documentation on how to do
this, I wonder what exactly are the requirements around the source
code for a module being available for packaging another module.  Does
the source (*.java)  have to be in the same jar or does it just have
to be on the classpath?

Maven's general approach is to make source available in a secondary
artifact using the maven-source-jar[2].  This is nice because it
removes bloat from my endstates but also I don't have to worry about
shipping source code to each of my clients.

So do I have to have *.java files in my jar or are there other means
of accomplishing this to make the GWT compiler happy?

Thanks for your help,
Micah

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[ckendrick]

@Jeff, ahhughes: as far as the built-in GWT widgets, they are well-
designed and fine for simple things, but if your requirement is to
have a grid that supports full-row inline editing, grouping,
filtering, frozen columns, paging through large datasets, resizable/
reorderable headers with persistence, nested headers, all of this
active at once - or if you need even a significant subset of this
functionality - this will take you a minimum of 2 years with core GWT
and you will achieve it really only with a ground-up custom widget
that you will need to maintain.  So it's just a matter of recognizing
that many people have requirements that go way, way beyond the core
GWT widgets.  Google employees have posted a number of times
acknowledging this.

Note that even if you don't have hard requirements for these features,
the fact is that they make your application better, and you will never
have to deal with a user request for such a feature: it's already
there.

ahhughes as far as your #2, please point to examples.  Almost everyone
who has *actually tried* SmartGWT remarks on the extremely low number
of bugs.

@Tercio, mariyan: unclear on why you found server integration with the
SmartGWT LGPL version difficult.  All you need to do is expose your
EJBs as REST services and there are countless tutorials on the web on
how to do this, as well as frameworks that can do this from Java
annotations.  People achieve this all the time.

Tercio in particular, I'm guessing this was you:

http://forums.smartclient.com/showthread.php?t=5632

You took the wrong approach, and our Support staff told you it wasn't
a good idea and gave you appropriate alternatives.

As far as "useless" features, if you think they're useless, you
frankly have not absorbed what they actually do.  Remember, Isomorphic
is a consulting company too.  We build applications in defense, life
sciences, insurance, financials and many other verticals.  We use the
features of Pro/EE *every single time*.

Re: "fixing" javascript method names

[Ryan Heaton]

Thanks for your reply. But I'm having trouble understanding your code.

The "publishGetStuff" method refers to $entry. What is that?

The "staticGetStuff" method refers to a variable "service". Where is
that variable stored?

It looks like when users call $wnd.getStuff then they have to pass in
a function, when I want them to pass in an object with a function
defined that matches the name of MyCallback.onSuccess method.

Thanks-

-Ryan

JSONParser bug ?

[Costa]

I have attempted the following code snippet:

String data = "new $wnd.Date(2010,0,28,17,8,48,0)";
JSONValue value = JSONParser.parse(data);

To my dismay it returns a JSONNumber !!

Now I looked in the source code (JSONParser.java: parse, evaluate &
createObject) and I created the following test program.


String data = "new $wnd.Date(2010,0,28,17,8,48,0)";
myParser(data);
...

  private native void myParser(String data) /*-{
var x = eval('(' + data + ')');
$wnd.alert(" typeof = " + typeof x + ", valueOf = " +
x.valueOf());

  }-*/;


The alert displays typeof = object and in valueOf = 1264727328000.

Because typeof = object the execution flow calls createObject:

private static native JSONValue createObject(Object o) /*-{
if (!o) {
  return @com.google.gwt.json.client.JSONNull::getInstance()();
}
var v = o.valueOf ? o.valueOf() : o;
if (v !== o) {
  // It was a primitive wrapper, unwrap it and try again.
  var func =
@com.google.gwt.json.client.JSONParser::typeMap[typeof v];
  return func ? func(v) :
@com.google.gwt.json.client.JSONParser::throwUnknownTypeException(Ljava/
lang/String;)(typeof v);
} else if (o instanceof Array || o instanceof $wnd.Array) {
  // Looks like an Array; wrap as JSONArray.
  // NOTE: this test can fail for objects coming from a different
window,
  // but we know of no reliable tests to determine if something is
an Array
  // in all cases.
  return @com.google.gwt.json.client.JSONArray::new(Lcom/google/
gwt/core/client/JavaScriptObject;)(o);
} else {
  // This is a basic JavaScript object; wrap as JSONObject.
  // Subobjects will be created on demand.
  return @com.google.gwt.json.client.JSONObject::new(Lcom/google/
gwt/core/client/JavaScriptObject;)(o);
}
  }-*/;


Please note the line:

var v = o.valueOf ? o.valueOf() : o;

What is the reason for doing this? It changes the type of object to
something that is not and that is a number.

Thanks

Re: Maven users survey

[Keith Platfoot]

Yes, I've been meaning to reply back to this thread.  Thanks for reminding
me, Brian! :-)

Our plans for the next release of the Google Plugin for Eclipse (1.3)
include 4 changes designed to make integration with Maven and J2EE projects
easier:

   1. The WAR directory can now be configured to be *any* project-relative
   path (e.g. src/main/webapp if you're using Maven).  You'll also be able
   to specify whether that directory is source-only (typical Maven/J2EE
   scenario), or whether it should also function as the WAR output directory
   from which to run/debug or deploy to App Engine.  If your WAR directory is
   input *and* output (which will remain the default for new Web App
   projects), the plugin will manage synchronizing the contents of WEB-INF/lib
   WEB-INF/classes with your project's build path and compiled output.
Otherwise, we'll leave your WAR source directory alone and you'll need to
   specify your WAR output location when launching, deploying, etc (the plugin
   will remember the location once you set it the first time).
   2. The Web App launch configuration UI is being redesigned to allow you
   to see, and if necessary change, *any* of the launch arguments.
Previously, we were waiting until launch time to set many of these
   arguments based on heuristics that were invisible and inaccessible to you.
Now you'll be in full control of how your projects get launched.  Also,
   we're adding the capability to automatically migrate your launch
   configurations when necessary, for example, updating the -javaagent flag
   when changing App Engine SDKs.
   3. GWT/App Engine projects will no longer require our SDK library on the
   classpath.  This means Maven users will be able to pull in JAR files from
   their M2 repository as they're accustomed to and the plugin won't mind a
   bit.
   4. The severity of any problem marker generated by the plugin will be
   fully customizable via an Errors/Warnings preference page (similar to the
   Java Errors/Warnings page), letting you specify either Error, Warning, or
   Ignore.

We'll also be including a few smaller features and bug fixes as well.

What does everyone think about the 4 changes outlined above?  We've been
testing the plugin against various Maven and J2EE configurations to try to
ensure that we've eliminated the most critical roadblocks.  However, we're
very interested in also having you folks take it for a spin before the
official release date (slated for next month).  We're not quite ready yet,
but stay tuned for a 1.3 preview build to be made available hopefully in a
few weeks.  We'll distribute it as a zip file for dropin
installation
so
it will come with the standard warnings and caveats (use with a clean
Eclipse install and workspace, use at your risk, etc.).  However, it will
hopefully give you a chance to give us any last-minute feedback about our
changes before the final release.

Thanks,

Keith

Cannot get code splitting to work

[Jonathan]

If I create a basic GWT 2.0 project, and add some basic code
splitting, it works perfectly fine.

But our main application is pretty massive and complex.  I cannot get
it to split ANY code whatsoever - even the most basic test.  I
generally confirm this by looking at the soyc compile report but it's
also obvious since there's no deferredjs folder.

My most basic test involves creating an incredibly basic POJO class
and referencing this class only from the onSuccess() method of the
runAsync callback.

GWT.runAsync(new RunAsyncCallback()
{
  public void onSuccess()
  {
  Info.display("Title", (new Bob("Code splitting
worked").getName()));
  }

  public void onFailure(Throwable reason)
  {
  Info.display("Code splitting failed", "Code splitting
failed");

  }
});

public class Bob
{
  private final String name;

  public Bob(String name)
  {
  this.name = name;
  }

  public String getName()
  {
  return name;
  }
}

The info messages (basic GXT class to display debug message) displays
"Code splitting worked".  But the report doesn't show any splits.  And
the class Bob shows up in the initial download. No matter where I put
these code splits and what I try to split, I cannot get any code split
to show.  There's no errors in the GWT compiler output.  We're using
the standard linker.  I really don't know how to proceed from here.
Can anyone provide any help?  Thanks!

Re: IE bug in vertical sizing of elements

[Thad]

Yay!  Kudos Tom.  Thank you.  Changing DOCTYPE to
http://www.w3.org/
TR/html4/strict.dtd">
clears up this  height problem.  I am now looking at three
devmode browser windows--Firefox 3.5 in Linux, IE7 in WinXP, and
Safari 4 on MacOS 10.5--and they all look the same.

Moreover (and the real acid test) is that my database forms now have
the same appearance as the Windows and Mac applications I'm seeking to
emulate.  Even when I change my widgets' fonts between our six default
fonts (Arial, Comic, Courier, Georgia, Times, and Verdana), their
alignments are the same as the Windows platform (the Mac guys may have
to tweak their stuff; hehehe).

Thanks also for the tip on Safari's Develop menu.  I wonder why I've
never seen any mention of it or the IE toolbar before on this board
I'm sure I've seen the question about Firebug like tool before, but
the only I read was a page called domviewer.html from http://www.brainjar.com/.
It's a clever piece of work, but not nearly so easy to use.

Is there any mention of these tools in the GWT docs?  I think these
tools should be called out at least in the FAQ's Troubleshooting
section.

Thanks again, Tom.  Much appreciated.

Re: GWT UIBinder - unrecognized text in g:VerticalPanel

[bkbonner]

Hey, question for you...How do reference the DialogBox in the java
code?   I was under the impression that it was only possible to do the
bind the java code to an entity with the same name.  Maybe I'm missing
something here.  Is the DialogBox an element of a Composite or is it a
separate definition.  I'm hoping it's a separate definition, but I
can't wrap my head around how to make it happen.

Any chance you can give a larger snippet of how you're referencing the
dialog?  Or maybe a working example?

Thanks,

Brian

GWT 2 - Different behavior when using DevMode/draftCompile then in Production mode

[Steve Lancey]

Hi,

We are experiencing a strange problem: We have a piece of code in our
application that is generating a html string which we are displaying
at one point in the application flow.
With GWT 1.5.x - GWT 1.7.x this worked without any issues. Moving to
GWT 2 this functionality is broken:
As a matter of fact, it is working in DevMode or with -draftCompile or
with -style = Detailed || pretty, but NOT in production mode.

E.g. one of the things that happen in production mode: a final
variable (final String uniqueId = DOM.createUniqueId();) becomes null
at one point. How is this even possible?

Thanks + Regards,

Steve

Re: Maven users survey

[bkbonner]

And hopefully (Nir mentioned this prior), there will be a way to
exclude  a specific set of classes via some 'ant matcher' from the
module.  We keep the path the same and it looks like GWT looks at both
directories and throws errors which I don't believe affect execution,
but are confusing:

   Validating newly compiled units
  [ERROR] Errors in 'file:/C:/work/bigproject/src/test/java/com/
example/gwt/client/ui/SampleUiTest.java'
 [ERROR] Line 43: No source code is available for type
org.mockito.Mockito; did you forget to inherit a required module?
 [ERROR] Line 48: No source code is available for type
org.mockito.Matchers; did you forget to inherit a required module?

In our module we have:

  
  

where client holds the UI code and common holds DTO classes between
the RPC Server and Client.  The common is probably redundant to a dto
package, but nevertheless.  If I move my test out of the package
specified by client, the error goes away.
gwt compile or specify ant expressions for gwt compile. Our convention
(and I believe a maven convention) is for test cases to exist in the
src/test tree with the same path as the class under test in the tree:
src/main.

Hopefully that makes sense.

Re: Prevent class conversion when compiling modules

[getaceres]

You are right, I didn't realize about the polymorphism problem since
you can always get an Object or interface as parameter and then
execute any of its methods, so you don't know what class you might
get. I guess a simplification of the problem would be to mark as
invalid only the field and its getter and setter so, any other method
which use the field or the getter or setter, even in class B, must
fail the compilation and also fail if either the fields or its
accessors override any method.

Something like this maybe (not tested, just an idea):

private static void publishGetStuff(MyService service) /*-{
   $wnd.getStuff = $entry(@my.package.Foo::staticGetStuff(Lcom/google/
gwt/core/client/JavaScriptObject;));
}-*/;

private static void staticGetStuff(final JavaScriptObject onSuccessFn)
{
  service.getStuff(new MyCallBack() {
public void onSuccess(Stuff stuff) {
  nativeOnSuccess(onSuccessFn, stuff);
}
private void native nativeOnSuccess(JavaScriptObject onSuccessFn,
Stuff stuff) /*-{
   onSuccessFn(stuff);
}-*/;
  }
}

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[siberian]

We don't want nested grids. We don't want nested html. We want a
nested composite panel with arbitrary widgets in them. Neither
framework does well there, hence the custom solution.

Anyhow, we'll be looking on our next project and seeing how we feel
about it. Extended GXT was very simple for us once we got over the
learning curve and SmartGWT will have the same learning curve.

"fixing" javascript method names

[Ryan Heaton]

Hi.

Here's my problem. I've got a GWT client-side service method that
makes a remote call to a server. Since the result of the remote call
is returned asynchronously, the service method takes a "callback" as a
parameter. It's basically just an interface with two methods
"onSuccess" and "onFailure".

So everything works great when invoking the service from GWT code, but
the problem is exposing this service method to be invokable by a
separate javascript library. Exposing the service method is possible
with tools akin to GWT exporter, but the problem is with the callback.
The "onSuccess" and "onFailure" methods are obfuscated by the compiler
so I have no reliable way to create a callback object from handwritten
javascript that will work when that method is invoked.

Here's an example for the sake of clarity. Let's say I've got a
service interface defined like this:

public interface MyService {
  void getStuff(new MyCallback());
}

And the "MyCallback" interface is defined like this:

public interface MyCallback {
  void onSuccess(Stuff stuff);
}

Let's say I bind the "getStuff" method to a javascript method of the
same name. I can then invoke the method from javascript, but I have no
way of reliably constructing an instance of "MyCallback" from
javascript because I don't know what the "onSuccess" method will be
named in javascript after is passes through the GWT compiler.

What I'd really like is to be able to define my callback like this:

public interface MyCallback {
  @PreserveMethodName //or some annotation like that.
  void onSuccess(Stuff stuff);
}

And then my javascript would look something like:

var callback = {};
callback.onSuccess = function(stuff) {...}
getStuff(callback);

Thoughts? Any suggestions for me?

Re: Embedded jetty

[vachi]

assume that you want to define jdbc datasource using jndi, here is
what I did.
1 add jetty-naming and jetty-plus jars to y
classpath. also put jndi.properties in your classpath.
2 implement a helper class, which implements jetty's
ServletContainerLauncher interface.
3 put jetty-env.xml in your WEB-INF
4 launch Hosted mode with argument -server (your helper class)

works with gwt 1.7

Override default CSS

[Mirandus]

Hello!

Whats the best way to override the default CSS-Style for the
DecoratedStackPanel?

In my case, i want to set the padding of the style class "gwt-
StackPanelContent" to zero - but i have no idea how to access the
wrapper-element and override the style.

If i put

.gwt-StackPanelContent {
  padding: 0px 0px 0px 0px;
}

in my own css file, then this style is overwritten by the standard.css
style.

Thanks!

Re: forget DTO, Dozer and Gilead use @GwtTransient [tested on GWT 2.0.X]

Ok.

About the @GwtTransient, in my case, I´m only using model classes
defined within the GWT module. Although I love what Gilead has done
for us, I think if it would be possible to eliminate the performance
overhead and let GWT serialize my JPA annotated classes directly.

Would it?

Could you file a bug in the GWT issue

Re: IE bug in vertical sizing of elements

[Thad]

Thanks, Tom.  It seems like a bug in IE:

1) I'm already using

for my page.  Should I be using a different one?

2) From Firebug, the Firefox style for the  is
"width: 128px; height: 1px; background-color: rgb(123, 123, 123);
position: absolute; left: 5px; top: 13px;"
>From the IE Developer Toolbar the style is
"LEFT: 5px; WIDTH: 128px; POSITION: absolute; TOP: 13px; HEIGHT: 1px;
BACKGROUND-COLOR: #7b7b7b"

So it's been set correctly in the DOM, but it's drawing entirely
wrong.

If there are not other ideas, I guess I'm gonna experiment with an
 element with a noshade style and hope I can position that
correctly on my page.

BTW, Tom, thanks for the tip on the IE Developer Toolbar.  I've used
Firebug since its inception, but this is the first I've heard of the
IE Developer Toolbar, although I've seen many people here ask if there
was a Firebug like tool for IE.  Do you know if there is such a
creature for Safari?

Yeah, this was a big problem for us since it meant creating lots of DTOs and
server-side routines that generated them from its existing objects and could
consume them for updates.

I don't know the internals of GWT compiler, but it sure would be nice if
fields and methods and constructors could be annotated to be ignored and

GlassPanel in IE6 -- color changes when scrolling

[Skyfort]

Hello internet!

I am using a GlassPanel to black out the background a bit when I open
a modal. In IE6, which of course uses the iframe shim, the color of
the GlassPanel is going from a dark grey to a light grey after I
scroll (sort of whiting out the background instead).

I can provide code if necessary, but mayhaps this is a problem that
has been seen before?

Thanks!

JUnitShell - specify HTTP port

[djd]

Hi guys,

Is there a way to specify the port when starting a GwtTestCase? By
default, this is set to 0 (random port). I would like to always start
on a specified port, and "-port 15000" didn't have any effect -
although I think this "port" has nothing in common with HTTP client
(but rather Jetty's port).

  Starting HTTP on port 0
HTTP listening on port 38031

Thanks a lot,
Regards.

PS: I am using a proxy & REST architecture to communicate with
backend, so I would not touch anything in my config (apache's Proxy/
ReverseProxy, apache listening on multiple ports, etc).

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[Tercio]

@mariyan nenchev, I used SmartGWT free version for some time and it
was a pain to integrate with EJB(To be honest I gave up). I considered
the paid version, but it's too expensive. You receive a lot of
"useless" features. You can't choose the ones you need, you must buy
the whole package.

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[Tercio]

@mariyan nenchev, my bad, I forgot to mention that it's a EE feature.
But the UI is available in the free version.

GXT API is much like the AWT API.

Re: Prevent class conversion when compiling modules

[Chris Lercher]

GWT doesn't allow reflection, but it does allow polymorphism. Let's
assume your client uses interface IC which is implemented by C1 and
C2. Now C1.x() is marked as invalid, but C2.x() isn't. Now your client
also can't use IC.x() anymore. It better not be toString()...

This is just one example for the strange semantics this would create.
I don't say that it's necessarily bad, but it's so different from the
semantics we're used to expect from a compiler. For me, one of the
most important things about a compiler is reliability. This doesn't
only mean that it should ideally be free from bugs. It means, that it
must be easy to determine which things will compile, and which won't.
Otherwise, we'll end up with something that's even worse than a C++
compiler: Slow, and little tooling support compared to Java (it's
incredibly hard to write good tools for C++, because the semantics are
too complex even for really good tool developers.)

Still I somehow like your idea. It just shouldn't be part of the
compiler. If it happens in a pre-compilation step that can be done
independently of the compiler, everything is fine, because then we can
keep our compiler simple and reliable.

I had problems with Sun JDK as well. However it would be more useful
for us if you outlined the precise problem you are having.

Are you, for example, using eclipse?

Re: Prevent class conversion when compiling modules

[dolcra...@gmail.com]

Well as a work around to see if/where gwtc is needing class A you
could create a "dummy" class using the super directive in your module
gwt that is serializable (and empty).

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[Ben]

I've been using GXT for a while, and as previous posts have mentioned,
the amount of documentation is pretty sparse. I've been able to
overcome that by relying on their extensive set of demo apps, and by
reading through the API's source code. If you're comfortable reading
someone else's Java code, then you'll be able to figure out how to use
it. IMHO, I'd rather have zero documentation instead of bad/wrong
documentation.

The features I like about GXT are:
  - The UI looks super clean and polished
  - I actually like the layouts managers - I spent too many years
doing Swing, so my brain is warped into understanding things like
BorderLayout.
  - Its developed by the same company/group/people that work on EXT
  - The grid can easily handle "large" sets of data (1000 rows per
page, with delayed rendering). One of the previous posts griped about
no server-side integration, but I disagree - GXT provides objects like
BasePagingLoadConfig and BaseTreeLoader for asynchronous on-demand
loading of data.

I haven't used SmartGWT, so it probably has many of these same nifty
features. I basically had about a day to pick one, and so far GXT
hasn't disappointed me.

Good luck!

Re: MVP with GWT 2.0/UiBinder could be simplified

[FKereki]

Hi!

Personally, I do not use the "HasX" methods. The way I use MVP
+UIBinder to create SomeForm is:

* SomeFormView creates its widgets through UiBinder, which are in
SomeFormView.ui.xml. SomeFormView implements SomeFormDisplay (see
below) which is the interface that SomeFormPresenter expects.

* SomeFormDisplay is an interface, that is implemented by
SomeFormView; this includes getters and setters, but doesn't provide
direct access to any widget. This interface also includes methods to
define callbacks, which are used by SomeFormView when it wants to
return data to SomeFormPresenter, or whenever an event occurs that
needs be handled by SomeFormPresenter. Events are linked to these
callbacks by using @UiHandler; the corresponding code just invokes the
appropriate callback.

* SomeFormPresenter receives a SomeFormDisplay object in its
constructor; thus, it cannot interact with the SomeFormView except
through the SomeFormDisplay interface. Just about the first thing
SomeFormPresenter does, is create appropriate callbacks, and set them
(through the SomeFormDisplay setSuchAndSuchCallback(...) methods).

Is this explanation clear? Is this closer to what you expected?

Best regards,
F.Kereki

[blopes]

Hi people,

Can you provide an example of integration with flirck and youtube ?

OR there is an others options to deal with photos and videos, using

Re: Prevent class conversion when compiling modules

[getaceres]

I chose the wrong letter to describe my algorithm. Going to my
example:

Class A not serializable.
Class B serializable but with a B.field of type A marked as transient.

In this case, only B has to be taken into account, which is the only
class that uses A. The compiler would ignore completely A and mark
B.field and all the methods in B which use B.field as invalid (not
translatable). If any class C uses a method in B which has been marked
as invalid, then the compilation fails. In this case, there isn't any
possible mistake. The only way to use B.field or any invalid method in
B and not declaring it in the code would be to use reflection, which
is not supported by GWT so if the code compiles, it will work for
sure. At least, no one will ever call any method which uses directly
or indirectly something related to A because in that case, the
compilation would have failed.

I don't know much about modern compilers (apart from flex and yacc)
and much less about the GWT compiler, but I don't think that
implementing this would be very complex. On the code analysis of B
(lexical or semantical) you put some information in a Hash Table which
is consulted every time another class uses B.something. Of course,
this will slow the compilation process, specially if B is a overused
class which has a lot of functionality, but at least for me, it would
be worth the extra compilation time just to be able to reduce my
duplicated code.

Re: Compiling in subdirectory

[cromoteca]

Hi,

thank you again Thomas. A solution might be to compile into /war/dir/
modulename and to use devmode into /war/modulename, pointing to a
different path according to the server I'm running on. I'll try that
approach.

Re: forget DTO, Dozer and Gilead use @GwtTransient [tested on GWT 2.0.X]

[getaceres]

We were discussing that annotation in this thread:

http://groups.google.com/group/google-web-toolkit/browse_thread/thread/71e0e7ca92425ad/0f1d4d5cf52875cb?lnk=gst&q...@gwttransient+#0f1d4d5cf52875cb

The annotation only works if all your classes with all the relation
classes belongs to the GWT module and all of them are serializable by
GWT.
If you have class A which is not serializable by GWT and class B which
is serializable but has a relation to class A (through a field and
their corresponding getter and setters), no matter if you use the
GwtTransient annotation, the compilation will fail saying that class A
is not serializable or that it does not belong to the module and that
it cannot find the source code.

Forget what I said about the documentation. But still, I never used
Annotation, I'll have to take a deeper look into this.

Re: Embedded jetty

[gcstang]

You can setup JNDI if this is what you mean.

Create a file in your war/WEB-INF as jetty-web.xml (MySQL example)


http://jetty.mortbay.org/configure.dtd";>





java:comp/env/jdbc/database


jdbc:mysql://localhost:
3306/mydatabase
username
password






You also need to add two jars (plus whatever you would need for your
driver) to your WEB-INF/lib folder :
jetty-naming-6.1.3.jar
jetty-plus-6.1.3.jar

Re: forget DTO, Dozer and Gilead use @GwtTransient [tested on GWT 2.0.X]

[philippe]

GwtTransient means that this attribute isn't serialized.

So if your List is not null you don't serialized this.

It would be great to stop using a 3rd party lib to process all DTO´s.

Remove element on host page

[obesga]

Hello

I have a div element into the host page, just a 'please wait' advice
while the gwt code loads.



  

  
  
  Loading application, please wait...
  


And I want to remove it from body when module loads, but I can't I
can make it dissapear by making the div invisible; but that isn't what
I want. This is what I've tried so far:

   public void onModuleLoad() {
   GWT.log("onLoad ",null); //TOLOG
   RootPanel.get().clear();
   if (RootPanel.get("esperePorFavor")!= null) {
   RootPanel.get("esperePorFavor").setVisible(false);
   RootPanel.get("esperePorFavor").clear();
   RootPanel.get("esperePorFavor").removeFromParent();
   }
//
 }

Has anyone other solution ?

Thanks in advance

forget DTO, Dozer and Gilead use @GwtTransient [tested on GWT 2.0.X]

[Diego Lovison]

In GWT 2.0.x you can use the annotations of the JPA and JDO without
problems and without using any additional library. Your source code
will be compiled normally. No exception (SerializableException) will
occur.

So what's the problem:
In a relationship one-to-many, when the GWT tries to serialize this
attribute that is a "List", will probably return an exception
(LazyInitializationException). Return an attribute that has a
relationship one-to-many is not good for various reasons, the
principal is the performace.

Solution
Add the annotation @GwtTransient above in the attribute "List" and
everything will work normally.

Advantage:
You use a native GWT solution to deal with this type of information.
Decreases some jars in your application, and get 10 ~ 200ms each
request.

If I were you, I'd install the IE Developer Toolbar (from Microsoft)
to check which styles are applied to the div. It might be something
related to default styles that you could override, or some weird
cascading/inheritence.
Also, switch to "standards mode" if your not already (just start your
HTML page with ""), as it could also be an issue with
the "box model", which is utterly "broken" in IE in "quirks mode":

The compiler always outputs into a subfolder (named after the module's
name or rename-to="") of the "war folder" (the one specified with the -
war argument, defaulting to "war").

You could give it "-war war/some", but then DevMode wouldn't work
(because it'd use "war/some" as the webapp root, so everything in war/
wouldn't be reachable, including war/WEB-INF).

The DevMode browser plugin communicates with the DevMode application
through a socket, and it's been reported that in some cases (in GWT
2.0.0) it hits the network instead of the loopback interface, which is
obviously much slower.
This is somehow fixed in GWT 2.0.1 by having DevMode *only* bind to
the loopback by default.

See the 2.0.1 release notes:

Not sure if it'll fix your issue, but using "javascript:" within
"event attributes" isn't even supposed to work.

The whole point of MVP *in GWT* is to make the presenter only depend
on "pure Java" classes, so you can unit test it in pure Java (no
GWTTestCase involved), which saves you precious seconds.
The goal is absolutely not to make it possible to exchange the view
with another implementation.

In practice, it also happens that you generally deal with styling et
al. in response to events; this much better fits in the view than in
the presenter where you won't be interested into such details (the
presenter doesn't care whether "view.highlight()" sets borders, a
different background, makes text bold or blinking, either by
manipulating the widget's getElement().getStyle() or setStyleName();
the presenter doesn't care whether a "button" is actually a Button or
a PushButton, or a Label or HTML, provided it HasClickHandlers; etc.)

It's all about pragmatic, not at all about overengineering. The idea
is to have as much things as possible in the presenter so you can unit
test it, but nothing that depends on JSNI (i.e. no Widget) so you can
unit test in pure Java.

You should really (re)watch Ray Ryan's talk:
http://code.google.com/events/io/2009/sessions/GoogleWebToolkitBestPractices.html

But in the end, this is all just a suggestion. You should do what you
think is OK, not what people tell you is OK. (but if you refuse to
follow some "best practice", you'd better understand what it's meant
to be useful for, what problems it addresses, etc. and compare this to
the pros and cons of your own approach before making a choice)

Re: Compiling in subdirectory

Hi,

thank you for your answer. It looks like I've not expressed my
question correctly, my fault since English is not my language.

I'm referring to GWT compilation, not Java compilation. To better
organize my project, I'd like to put GWT files (mymodule.nocache.js,
MD5*.html, gwt.rpc and so on) in /somedir/somesubdir inside the war
directory, but I've only been able to put them into /somedir

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[mariyan nenchev]

Yes it has very fancy widgets but the integration with the server side is
killing unless you decide to purchase pro/ee, which is why it is done that
way, to show the devs how rich library it is and when they began to use it
they understand that they must buy pro/ee else they will code hundreds lines
of code to do something simple. No body told me how many steps are needed to
list some data in table if your backend is EJBs and you are using GWT-RPC?

Re: Problem with Thread in GWT2.0

[mariyan nenchev]

Java script is sigle threaded, you can not use threads in the client side of
gwt project. Just use AcyncCallback.

  {
public void onClick(ClickEvent arg0)
{
GetStringServiceAsync service = (GetStringServiceAsync)
GWT.create(GetStringService.class);
service.getString("1", "2",new AsyncCallback()
{
public void onSuccess(String 
res)
{
label.setText(res);
}

public void onFailure(Throwable 
arg0)

Re: Gwt server side and maven

[olivier nouguier]

Hi
 Take a look at http://code.google.com/p/orcades-gwt-spring/
 I use maven, wtp and GWT.
 But AFAIK, the  springframework && jetty embed server doesn't fit well and
I cannot use jettty embed server.

Re: Upgrade problem 1.7 --> 2.0

[Rokesh]

hi,


this might be useful when switching back to GWT 1.7 from GWT 2.0

===
Note if you switch back to GWT1.7, you have to do the following:

Remove all files in C:\Documents and Settings\YOUR_USERNAME\Local
Settings\Temporary Internet Files\Content.IE5

see for more info:
http://groups.google.com/group/google-web-toolkit-contributors/browse_thread/thread/50ffb5b491f63f64?fwc=1
===

Regards,

Rokesh

Re: GWT 1.7 upgrade Issue in Linux

[Ignat Alexeyenko]

Hello.

Have no problems on upgrading my app to the new version of GWT.
Delete all the output GWT compiler directory.
Review all the warning/error messages that are shown by GWT compiler.

Re: How to write test cases (in GWTTestCase) to test UI components of GWT?

[Ignat Alexeyenko]

Hi.

You can create events and throw them to your components.
I.e. you can write something like that in GWT Test Case method:

Label label = new Label();
CheckClickedClickHandler handler = new CheckClickedClickHandler();
label.addClickHandler(handler);

NativeEvent ne = Document.get().createClickEvent(0, 0, 0, 0, 0,
false, false, false, false);
ClickEvent.fireNativeEvent(ne, label);

assertTrue(handler.isCalled());
assertEquals(1, handler.getCallCounter());

CheckClickedClickHandler - handler mock that counts onClick methods.

For more info, please refer to the correspondent documentation:
http://code.google.com/webtoolkit/doc/1.6/DevGuideTesting.html

Re: Gwt server side and maven

[Ignat Alexeyenko]

Hi.

Recently I've migrated my project to Maven.
There is nothing important there - just login form and 1 RPC call (project
is only started).

But the project is using maven with gwt plugin for GWT 2.0 compilation.
http://sourceforge.net/projects/simpleworklog/

Just checkout it somewhere and launch from project root:
*mvn package *
