Referenced libraries are missing

[Artem Baltser]

Hi there) Recently I deployed my app to GAE and got errors executing app...
I think the reason is that the part of referenced libs is missing for 
deployed version...
I guess GAE automatically takes all libs in war/WEB-INF/lib folder 
according to Java EE standart

Here's a peace of code I use to show classpath...


URL[] urls = ((URLClassLoader) (Thread.currentThread().getContextClassLoader
())).getURLs();
 for(URL url : urls)
 res+= url.toString() + "\n";

If you know the best way to show a classpath..show me plz)
So...What you think? What I need to do?

Is it possible to set sourceMapping URL different from CodeServer bindAddress?

[Artem Zatsarynnyy]

I have one problem with GWT CodeServer that seems no one has faced yet ).
I need to launch GWT CodeServer on a remote host www.example.com:9876 but I 
have some problem with SourceMaps.

So, I launch GWT CodeServer on a computer with specified -bindAddress 
parameter that equals to the computer's IP address in LAN (for example 
192.168.1.10). It works perfectly: when I go to www.example.com:9876 then 
DNS redirects me to the local machine in the LAN where CodeServer was 
launched.

But sourceMappingURL in the compiled *.cache.js files points to the 
computer's IP address in the LAN. Like this:
//@ sourceMappingURL=
http://192.168.1.10:9876/sourcemaps/_app/gwtSourceMap.json

Is it possible to set sourceMapping URL different from CodeServer 
bindAddress?

Re: Is it possible to set sourceMapping URL different from CodeServer bindAddress?

[Artem Zatsarynnyy]

Hi, Thomas!
Yes, of course, I have tried to set the host name as bindAddress, but in 
this case I get the mesage Can't resolve bind address. As far as I 
understand, it should be only local IP address.
Accessing to my server by its IP address doesn't solve the problem. My 
problem is that //@ sourceMappingURL is pointing to the local IP address.
Also, I have tried to play around the includeSourceMapUrl property in my 
gwt.xml descriptor:
set-configuration-property name='includeSourceMapUrl' 
value='http://www.my_host.com/'/
But it didn't change anything.

Re: Update of Eclipse Plug In Causes Compile Error

Re: How do you get uiBinder to inject its style code immediately?

[Artem Artemyev]

Hello!
Im trying to find a solution too and I stop on your resolving way: static 
boolean in the widget and injection by StyleInjector. But invoking 
StyleInjector.inject( style.getText(), true ); force inject styles and after 
few moments styles injected again! It happens because 
uiBinder.createAndBindUi(this) invoke style.ensureInjected(), that invoke 
StyleInjector.inject( style.getText(), FALSE ); that add style injection to 
the queue in the StyleInjector. Fortunately StyleInjector provide flush() 
method... 
And final solution is:

@UiField
Style style;

private static boolean styleInjected = false;

public SomeWidget() {
widget = uiBinder.createAndBindUi(this);

if (!styleInjected) {
styleInjected = true;
StyleInjector.flush();
}
}

RequestFactory and server side validation

[Artem Nikulchenko]

I'm trying to use RequestFactory in my application for entity exchange
between client and server. (Which I think it was designed for.) But I
have one workflow, that it kind of standard, but I can't solve it in
any normal way (with out overriding part of RF logic).

The workflow is follow:
1. User press New button and create new entity at the client side.
(RequestFactory used for that)
2. User put some data into this object (fills fields) and press Save.
3. Client side validation called and passed.
4. RequestFactory method is called to save entity.
5. Server-side method detects some problems with this data (data do
not pass some server-side validation) and want's to inform User about
that (using errorCode or throwing exception)
6. Client receives this info and show it to User.
7. User make corrections to the data and press Save again
--And here is where the problems start. I can't call persist method
again on same RequestContext, because it was already used and will
throw an error. I also can create a new RequestContext and attach
entity to it - because I can't detach it from previous RequestContext.

What I'm missing here? How server-side validation should work with
RequestContext?

Re: Data-binding, Konckout.js

[Artem Nikulchenko]

We are using Editors a lot. And they are coll (at least much cooler
than it was before). But they are still far way from full data binding
as shown in Knockout.js (or as it's done in Silverlight). I'm not a
fan of Silverlight and hope that GWT would remove all this plug-ins
soon, but watching GWT and Silverlight groups working is parallel in
out company - I could definitely say that Silverlight data-binding
style gives huge advantage and removes a lot of extra code.

GWT with Editors support WinForms style of binding, where each form
could be bind to the object and then editors values would be bounded
to properties of that object. In Knockout.js (and WPF and Silverlight)
I could bind ANY property to the values of binding object (that is
called context in that case) and get NotifyPropertyChnage support. For
example I could have panel (for example loading indicator), which
visibility is controlled by IsBusy property (get and set in Java).
Setting this property to false and true will automatically hide and
show the panel. Many more use cases could be shown...

Please check Knockout.js demo for more examples...

Is there are any plans to do the same in GWT?

Re: GWT and indexing

[Artem]

I'm thinking about inserting small JavaScript code into our
escape_fragment pages. So, first page is created by HTMLUnit, and
then small JavaScript code is inserted, that would redirect a User to
real !# pages. In that case Google Bot would see escape_fragment
static pages, while if some escape page was ranked by another
crawler, and User comes to it - User would be redirected to !# pages.

But I am afraid that this would be counted as a bad style and my site
will get into Google Black List (while I'm trying to worry about
another crawlers - Google is still number one! and I don't want to
disappoint it ) )

What do you think about this approach? Could you comment on chances to
get to Google Black List with this approach?

Thanks!

GWT and indexing

[Artem]

There were a lot of topics about crawlable GWT application and ways to
make them crawlable

Maybe somebody could share information about last changes on this
topic? Maybe some new information came?

I found last updates on
Making AJAX Applications Crawlable
http://code.google.com/web/ajaxcrawling/index.html

Described approach are doable (by require some additional coding to be
made (( )... Does anybody know if this is a common standard or only
GoogleBot supports it? Does other crawlers follow the same rules? Or
maybe this is not the last information and some other approach now
should be used?

Re: UIBinder, Refresh and binding

[Artem]

I am not looking for 2 lines solution for whole problem. I am looking
for solution which can be implemented once and then allow to bind
objects in 2 lines... And from what I understand - changing code of
UIBinder would be one of the ways to make this solution.

Can you help me with some links/examples/descriptions of changing
UiBinder code and/or implementing my own UiBinder?

UIBinder, Refresh and binding

[Artem]

Hi!

I am really enjoin using of UIBinder! But still some of my code looks
a bit strange and unpleasant in comparison with what I would like to
see... I'll explain in details:

Imagine I have a UIBinder component with some Label inside:
...
g:Label ui:field=label
...

In that case I can set a value to this label in java code like this:

@UiField
Label l;
...
l.setText();
...

Imagine I want to bind this panel to some object. As a result if this
data object has a lot of properties I end up with huge list of
@UiField declarations and setText methods, and after a while it get's
really hard to find out what property where should be displayed.

I would another approach that allows me to bind to some properties
inside the UI directly:

ui:with field='dataContext' type='com.toi.client.DataObject'/
...
g:Label text={dataContext.getValue}

Now this code looks already better, because now I can clearly see
where and what properties are displayed. I also don't need so many
setText methods in java class any more... But this approach solves
only one problem - bind UI to data object when UI control is
created...

What else do I need from it?

1. First, I would like to have a refresh method, so when I want to
display another object in the same control I will simple use
this.dataObject = newDataObject; refreshUI(); and trigger all
connected labels, textboxes etc. to call setText and other methods
again (In that case I won't need to re-create UI when new object comes
- only reloaded properties...)

2. Second. I also would like to have bi-directional link. Which means
- if I say g:TextBox text={dataContext.Value} not only text from
dataobject is loaded into textbox during initialization, BUT also data
object value is changed when somebody edits TextBox.

Maybe somebody could help me with this problem? Maybe somebody knows
some framework or workaround that could be used in that case?

Or maybe somebody could show me the way to somehow catch events from
my UIBinder object, so I can bind them manually to properties on base
class implementation?

Thanks!

Artem

GWT and Image Editor

[Artem]

Hi!

In my project I need specific GWT widget. Basically main request for
it - to allow place some text on top of Image and then safe a result.

It should work for company that produce business cards. User can go to
a web site, select any card template (basically just background Image)
and then be able to place some text on any place on top of Image and
somehow result should be saved to allow manager later to check it and
send to printing...

Does anybody could give me some advise on that? Any ideas how this
could be done in GWT? Maybe some nice framework that will make my job
easy?

Thanks

GWT and Maps - lazy loading

[Artem]

Hi!

I really enjoy GWT and Google Maps working together...
But I have a question about Lazy Loading of Maps scripts...

To use Google Maps in my project I have to add
  inherits name=com.google.gwt.maps.GoogleMaps/
  script src=http://maps.google.com/maps?
gwt=1amp;file=apiamp;v=2amp;sensor=false /
into my project xml.

As a result size of initial load of my web site increases for the size
of maps scripts... On the other hand I don't have Maps widget at first
page of my site - so it could be that User will never actually need
it...

Could I somehow create some kind of Lazy Loading for Goolge Maps and
load needed scripts only when they really needed? Maybe use
GWT.runAsync somehow?

GWT video/news/articles etc...

[Artem]

Hi All,

For long time I was looking for some cool website with GWT news,
video, articles etc. Because of my job I also have to work with .Net
technologies, and there I found Channel 9, and I must say at least for
me it looks like very nice way to follow .NET news and frameworks. I
tried to find something like that for GWT, but no success for now...
((
I've see list of videos from IO 2009, but no updates in articles and
videos after that...

Maybe somebody can help me and share a link to website where
developers who work with GWT (or even better if Google developers)
share there vision on GWT, GWT architecture, frameworks for GWT etc.?

Thanks!

Re: GWT hosting

[Artem Borodin]

How, then, without using Tomcat to lay out my project in Netbeans on online
server? I read that in the end should now have a WAR file, but he simply
will not work.

2010/1/22 Cristian Nicanor Babula nicanor.bab...@gmail.com

 Take a look at Google Application Engine. It is free. Of course, if you get
 high traffic, then it will cost you.

 There are now a growing list of ISPs whose web hosting packages

 Obviously, any ISP that offers a VPS package will do the job too.

GWT development process

[Artem]

I'm rather new in GWT and maybe I'm asking something really easy and
well-known, but I'm not able to find solution myself, so I really hope
you can help me...

I really like GWT but can't find a way to integrate in to our
development process.
We tried to do it as usual - we created cool HTML and CSS pages as a
markup and started to move all of that to GWT... And this became a
disaster for us ((
Almost everywhere we face different style problems... For examle, in
our CSS we have

input .test {}
input class='test' type='checkbox'...

In GWT we tried
CheckBox c = new CheckBox();
c.addStyleName('test');

but of course that was converted to

div class='test'
   input type='checkbox'...
/div

which mean CSS do not work any more.

This is just an example - we face different problems everywhere and
trying to create same page in GWT took us a lot of time. (If you add
to this that GWT could in next build change HTML presentation of
cotrol - it's even adds problems)

Of course in each case we could create a workaround... But it doen't
look like good way to use GWT in app. So it's probably some other nice
way to do this...

What we are doing wrong? What rules should we follow when creating
HTML/CSS? Or development process should be different and we shouldn't
create HTML first? Maybe somebody has a link to nice article which
could answer all this quesions?

contextual search in a ComboBox

[Artem Budnikov]

Hi, everybody.

Is there a method to set up contextual search in a ComboBox? (I mean
search not by beginnig of a displayed field but by an arbitrary part
of string) like search in a combobox when it is used with
PagingMemoryProxy.
I cannot use PagingMemoryProxy because I have to change data
dinamically and in this case combobox doesn't show new records.
If it isn't possible could anybody suggest how to make this without a
combobox?

Thank you.
