Re: table.getInnerHTML() not giving appropriate results

Yes, CellTable (and other cell widgets, a.k.a. Data Presentation Widgets in 
the docs) build an HTML string and uses innerHTML for best performances 
(well, actually, CellBrowser does use inner widgets, but it uses CellLists 
for each tree level for best performances).

Re: RequestFactory No fire

2011-01-13 Thread Metronome Basic

In fact I expected RequestFactory to behave somehow like GWT-RPC

My view ( probably wrong )

Your RequestFactory expose Interfaces to entities ( in my cas a single entity 
Person )

The Entity Person is a description of some data ( fields of SQL table for short 
)
The Person class is also used for the server side methods ( findAllPersons 
etc.. ) my getStr()

The PersonProxy interface is a representaion of Person for the client side
The PersonRequest interface is used to acces Entities 

then if I have 

public class Person {
public static getStr() { return whatever }
}

and 

@service(Person.class)
public interface PersonRequest extends RequestContext {
RequestString getStr();
}

I expect

factory.personRequest().getStr().fire(new ReceiverString() { 

to return my string

But I must be wrong !

Thanks to reply such naives questions

  A RequestContext (as returned by your personRequest() method) is a kind of 
builder for a request. Here, you're creating one such context, creating a 
PersonProxy within it, and throwing the RequestContext away, which makes the 
PersonProxy unusable (you can mutate it, but nothing else, including adding it 
to another proxy or sending it to the server, because it is attached to a 
context that you no longer have a reference to).

 
  //factory.personRequest().persist().using(person).fire();
  
final Button sendButton = new Button( Send );
final Button fireButton = new Button( Fire );

RootPanel.get(sendButtonContainer).add(sendButton);
RootPanel.get(sendButtonContainer).add(fireButton);


fireButton.addClickHandler (new ClickHandler() {
public void onClick( ClickEvent sender) {
//lh.setText(Handle =  + sqlBox.getHandle());

Window.alert(Fire);

factory.personRequest().getStr().fire(new ReceiverString() {



  I don't know what you expect from this code, but this is just asking for a 
String to the server, without any reference to a PersonProxy (or similar 
server-side entity).


  I don't realy like plugging my own writings in (I highly prefer when others 
do it for me ;-) ), but maybe my recent post on RequestFactory will help you 
understand the big picture(and you'll later re-read the GWT official doc with 
a fresh eye): http://tbroyer.posterous.com/gwt-211-requestfactory

Re: change the generated project template

Thanks for the suggestions.

I think I'll just create my template project, and copy, import it

This maven plugin seemed a bit overkill just for this, and I couldn't
even uninstall it. I had to delete its files manually. I'm pretty sure
I won't install it again.
I found something in the eclipse plugin development help though. And I
think it is possible to create a plugin just for that.
Maybe I'll check it out later, when I'll have time.

No, nothing special. Only if you create things in onAttach/onLoad you might

Re: Server Log

2011-01-13 Thread pete

Yes, but what about RPC-exceptions, that actually don't arrive
anywhere? (I think that is the case, where I'm stuck, but I have no
access to the deployed production webapp, and I'm told, that the logs
show nothing...)
I mean, if I actually arrive in the correct function on the server,
yes, then I could just do the logging as I'm used to.
I just think, I changed the return-value of an existing function and
somehow there is a problem somewhere, that I don't arrive in that
function anymore, or that the answer doesn't arrive back. If I look at
the firebug console, I see that my post-request fails, but I
surrounded the whole method, which is in question with try{..}catch()
{log} and still nothing... Which makes me think, I never arrive in
that method, and something goes wrong earlier... Or later, I don't
know...
But I would need a stacktrace to be logged like method bla doesn't
support correct return type - TargetInvocationExcaption: Stacktrace
in such a case. But I don't know how to log those things.
In development mode, yes, then I see any stacktrace like this. But
unfortunately there it works and I need to know what goes wrong with
the deployed version, and then there is no log at all (even though it
says check server log)
Is there any way to configure log4j to log those exceptions?

setwidth and setCellWidth of the VerticalPanel

2011-01-13 Thread Leung

Hi
 
I need to make the width of the VerticalPanel constant. I have tried setwidth 
and setCellWidth, but both seem not working well.

For example,

VerticalPanel vp = new VerticalPanel();
vp.setCellWidth(this, 400px);
Label textlabel = new textlabel();
textlabel.add(text); --
vp.add(textlabel);

If the text is a string containing various spaces, then the width is able to be 
kept because the wrap is on. Otherwise, if the text is a string without space 
longer than 400px, the string would not wrap. How can I make the width constant 
independent of the string?

Thanks

Unable to display html file in Frame container.

2011-01-13 Thread Barry

I developed a diagnostic app interface using GWT.  (Akin to a car diagnostic 
device on steroids).
Now need to allow subject matter experts to easily add/modify/maintain 
help-tips via separately developed Html files.

I can select  display web sites in a Frame container, but yet unable to get 
an html file to display in Frame.

Believe problem is how html file is addressed.

Simple test cases in development mode don't display anything yet, using GWT 
2.0.3:

// 1.)  test.html was located in BaseUrl dir
   String xxx = GWT.getModuleBaseURL() + test.html;
   frame = new Frame(xxx); 

// 2.)  Hardcoded url:
   frame = new 
Frame(http://127.0.0.1:/com.mycompany.project.test.html;);

// 3.)  Put test.html at top of C drive:
   frame = new Frame(http://127.0.0.1:/C:/test.html;);

Where am I missing the boat, or maybe you have a simple example ?

Thankyou in advance.  Barry

Multi-Module Project and Servlet Mappings

2011-01-13 Thread rsimon

Dear all,

I have a project which consists of multiple modules. Basically, it's
four separate GWT applications which share some common code. There's a
separate module for each of the four applications, plus a 'core'
module for the common functionality.

Now my problem: The common functionality includes server-side RPC
endpoints. I have defined the servlet paths for those endpoints in
the .gwt.xml file of my core module as

servlet path='/endpointA' class=.../
servlet path='/endpointB' class=.../

and so on. Now - when I inherit the core module in my app modules, GWT
insists that the endpoints are mapped to

/AppName/endpointA rather than just /endpointA

So far so good. But as a result, I need to provide 4 servlet mappings
in my web.xml, each pointing to the same service impl class. E.g.
something like this:

servlet
servlet-nameendpointAservlet-name
servlet-classmy.gwtapp.server.EndpointAServiceImpl/servlet-class
/servlet
servlet-mapping
servlet-nameendpointA/servlet-name
url-pattern/AppOne/endpointA/url-pattern
url-pattern/AppTwo/endpointA/url-pattern
url-pattern/AppThree/endpointA/url-pattern
url-pattern/AppFour/endpointA/url-pattern
/servlet-mapping

Ok, it's not a showstopper. But I can't believe there's no better way
to share servlets across modules than by repeating the mappings for
each module?

Any advice appreciated!

War structure for multi-module app has changed magically

2011-01-13 Thread Allen H

Using GWT 2.1.1 and Eclipse Helios SR1/mac (but this behavior has been 
around since 1.6 --- it's just now become a problem, though).

I have an app that has several modules, each in its own source-directory 
system (and each as a separate Eclipse project, for that matter). It used to 
be that each module was compiled to its own subdirectory of the war 
directory. In fact, this still seems to be the default behavior.  A few days 
ago, however, GWT started munging all the modules together into the main 
application's module directory.  That is, instead of
  
war
+mainAppModule
+supportModule0
+supportModule1
...

I now have a single mainAppModule diretory that contains everything that 
used to be in three separate subdirectories. There are name conflicts with 
some of the HTML files, so this single-directory structure is a problem.

I can't for the life of me figure out what I did to make GWT start behaving 
differently, but I really want to go back to the original 
one-directory-per-module structure. (All of the module elements, by they 
way, have rename-to attributes, but I didn't change any of that so I don't 
*think* that's the issue.) 

Anyway, if anybody could either tell me how to force GWT to use the 
multi-directory organization of the war, I'd really appreciate it. I'm 
hoping that there's some simple flag or XML attribute that I've just missed 
when I perused the docs.

Re: War structure for multi-module app has changed magically

2011-01-13 Thread Barry Kravitz

Y2i;

Thanks for the reply.

I haven't played with UI binder yet, so I don't want to waste your time in
this approach until I do some homework.

And, no I don't play with the modules' rename-to attributes.

Without going down this path yet, I should note that I would like to get
html file paths from server via callback messages. E.g. After getting
results from diagnostic A, get the current list of relevant html files
associated with diagnostic A from server. So, without asking you to solve
'my' problem, It would be interesting to know if the UI binder or rename
schemes might yield a solution where path names would not be fixed at
compile time.

thanks again - Barry.

Using multiple views in one place

2011-01-13 Thread Owen Ilagan

Has anyone tried using multiple views in one Place then having
separate activities for each one? This scenario occurred to me when I
wanted to save work on having to repeat the same header for multiple
Places in my application. It was done using one view as a container,
acting like a frame for a header view and a body view so that every
time my app would move from one place to another, the activity code
would just get the root view then replace the child widget in the body
with the view I wanted to show thus keeping the header view in place
without having to repeat it all over different views if I didn't use
this technique. It works fine, except that I am bothered by the fact
that I have a Place and Activity for the header view separate from the
others which is doesn't quite fit the essence of Activities and Places
as I understand them. Ideally, there should be only one Place and
Activity for each page in my application. It just so happens that in
order to save coding for sections of a place that are repeated over
many places, I have to define a separate Place and Activity class for
it. Perhaps there could be a new concept that will cover this gray
area that would make it easier explain separately defined repeating
sections of a Place.

Using APT to generate Classes under Eclipse

2011-01-13 Thread Thomas Lefort

Can anybody help me use my custom made annotation processor (for GWT
Request Factory) under Eclipse?
I have developed an eclipse plugin with a custom annotation and its
processor (using java6processors). I export it to a jar file and add
it to my classpath as well as to my apt processor (under the compiler
apt option), but nothing happens. I am a bit clueless as how to debug
it (Messager doesn't output anything) and there is very little doc on
the web. I saw a few processors out there, eg with GUIT or with GWT-
APT. If someone knowledgeable and kind enough can help me out...

Overriding Entrypoint on Inheritance?

2011-01-13 Thread rsimon

Dear all,

I'm trying to create a project with two modules, where one module
'extends' the other. The basic use case is that both modules are GWT
apps. One just has the basic feature set, and the other one adds
advanced features. The problem, now, is that both have an entrypoint
defined in the .gwt.xml. I realised that when I launch the extended
module, both EntryPoints get called.

Is it possible to 'override' the entrypoint of the base module in the
extended module? So that only the entrypoint in the extended module
gets called? Or am I missing something and do I have to arrange my
project entirely different?

Tomcat vhost - Servlets not available

2011-01-13 Thread Johannes Stein

Hey,

i deployed a gwt-application in tomcat 6.0.18 without any problems. I
pointed a url to the ip-adress and deployed the application unter
webapps/myfolder, so that the app was reachable unter http://mydomain/myfolder.
It worked fine.

But since im using a vhost in tomcat i got a problem.
Every time when gwt tries a callback i get the message: Requested
resource not found. I did not make any changes in the web.xml.
I added the host like the following in the server.xml:

...
!-- Define the default virtual host
   Note: XML Schema validation will not work with Xerces 2.2.
   --
  Host name=srv2.tudom.de appBase=tudom
   unpackWARs=true autoDeploy=true
   xmlValidation=false xmlNamespaceAware=false
/Host

 !-- VIRTUAL HOST INJECTION POINT --

/Engine

The code is deployed into the folder tudom. The .html works fine, but
my callbacks dont work.
A snippet from my web.xml:


servlet
servlet-nameStartService/servlet-name
servlet-classtudom.start.server.StartServiceImpl/servlet-class
  /servlet
  servlet-mapping
servlet-nameStartService/servlet-name
url-pattern/tudom.start.Start/StartService/url-pattern
  /servlet-mapping


When im changing the URL-Pattern to

url-pattern/tudom.start.Start/StartService/url-pattern

the Servlet gets reachable, but this doesnt interest GWT, cause it
still tries to load /tudom.start.Start/StartService.

Could everyone help me? Im now searching some hours and cant find
anything. Hope you can help me.

Greetings

Re: Server Log

2011-01-13 Thread SVR

true, I don't see the ability to configure server side log anywhere.
I would try this:
Enable gwt.logging.firebugHandler and see atleast the umbrella exception...

 Yes, but what about RPC-exceptions, that actually don't arrive
 anywhere? (I think that is the case, where I'm stuck, but I have no
 access to the deployed production webapp, and I'm told, that the logs
 show nothing...)
 I mean, if I actually arrive in the correct function on the server,
 yes, then I could just do the logging as I'm used to.
 I just think, I changed the return-value of an existing function and
 somehow there is a problem somewhere, that I don't arrive in that
 function anymore, or that the answer doesn't arrive back. If I look at
 the firebug console, I see that my post-request fails, but I
 surrounded the whole method, which is in question with try{..}catch()
 {log} and still nothing... Which makes me think, I never arrive in
 that method, and something goes wrong earlier... Or later, I don't
 know...
 But I would need a stacktrace to be logged like method bla doesn't
 support correct return type - TargetInvocationExcaption: Stacktrace
 in such a case. But I don't know how to log those things.
 In development mode, yes, then I see any stacktrace like this. But
 unfortunately there it works and I need to know what goes wrong with
 the deployed version, and then there is no log at all (even though it
 says check server log)
 Is there any way to configure log4j to log those exceptions?

Re: Problem with serverside code

In a standard rutime environment, yes, but not on App Engine.

Maybe yo don't need to run in the AppEngine sandbox, so you can disable 
AppEngine in your projects' properties (IIRC, you'll probably have to delete 
a bunch a JARs from your war/WEB-INF/lib after the change)

Re: Detect CSS3 and HTML5 features supported by the browser with GwtModernizr

How about using deferred binding? (you already use it but in a very limited 
way)
in other words, splitting Modernizr's code into property-providers (and 
with fixed values when possible: i.e. almost nothing is supported in 
user.agent=ie6, history.pushState is supported in user.agent=ie8, etc.), 
combined with soft-permutations to avoid permutation explosion (at least 
in the number of generated files; I haven't ever used soft permutations so I 
don't really know how it all works)
This would allow users of your library to do the NativeVideoPlayerWidget 
vs. FlashVideoPlayerWidget, or NativeDateBox vs. DateBox choice using 
deferred binding rather than if/else branches.

Re: setwidth and setCellWidth of the VerticalPanel

2011-01-13 Thread John LaBanca

VerticalPanel is implemented using a table, which means that it will always
auto expand to fit its contents. If you want to ensure that it is 400px,
wrap each child content in a FlowPanel and set the width of the FlowPanel to
400px and overflow to hidden (or scroll).

Thanks,
John LaBanca

I need to make the width of the VerticalPanel constant. I have tried
setwidth and setCellWidth, but both seem not working well.

For example,

VerticalPanel vp = new VerticalPanel();
vp.setCellWidth(this, 400px);
Label textlabel = new textlabel();
textlabel.add(text); --
vp.add(textlabel);

If the text is a string containing various spaces, then the width is able
to be kept because the wrap is on. Otherwise, if the text is a string
without space longer than 400px, the string would not wrap. How can I make
the width constant independent of the string?

Re: Overriding Entrypoint on Inheritance?

All entry points are called:
http://code.google.com/webtoolkit/doc/latest/DevGuideOrganizingProjects.html#DevGuideModules

Do you need 2 entry points?  If you want to use a base module as a separate 
app, you can create a third module, move the entry point from the base 
module there and inherit the base module from the third module.

Re: GWT throwing java.lang.UnsatisfiedLinkError when trying to make http requests using URL encoding

You cannot use the *.client.* classes on the server (there might be a few 
exceptions, but it's the general idea that things that can run server-side 
are in a *.shared.* or *.server.* package). This includes the URL class.
The UnsatisfiedLinkError is due to the notation used by GWT for JSNI: they 
are 'native' methods (i.e. things a JVM expects to find in a DLL or 
equivalent).

In your case, have a look at the java.net.URLEncoder class.

Using browser specific selectors in CssResource

2011-01-13 Thread Marcin Misiewicz

Hi 

Is it possible to use browser specific selectors like I used in this 
following statement in the CssResource's css file :

button::-moz-focus-inner,
button:focus::-moz-focus-inner {
border: 0;
padding: 0;
}

The compiler is stripping this declaration from the result.
Is it possible to tell the compiler that it shouldn't get stripped ?

Maybe I can use literal function with this selector in some magic way ?

GWT 2.1 MVP with DockLayoutPanel

2011-01-13 Thread Sam Stephens

Hi all,

I'm having problems with the new MVP framework and using
DockLayoutPanel or SplitLayoutPanel. If I switch my code to use
RootPanel and DockPanel then it will work, but if my views are using
a  DLP or a SLP inside a RLP then it simply does not render the centre
pane.

Any tips ?

Can I build a graphic widget on server side and send it to the client?

2011-01-13 Thread Jack

Hi all.
I'm using GWT 2.0

In my application I have to render on the browser an html form with a
lot of input widgets such as textfield, checkbox, and so on.
The exact composition of such widgets is stored in a database; in
other words I don't know how the form must look like a-priori, but I
need to build it dynamically based on what's stored in the db.

I'm trying to follow this approach: the client send and RPC request to
the server side of the application through a method that returns a
VerticalPanel, like this:

public class MyServiceImpl extends RemoteServiceServlet implements
MyService {
public VerticalPanel getMyForm() {
VerticalPanel pan = new VerticalPanel();
...
pan.add( new TextBox(...) )
...
return pan;
}
}

This approach leads me to this error at compilation-time:
[ERROR] com.google.gwt.user.client.ui.VerticalPanel is not assignable
to 'com.google.gwt.user.client.rpc.IsSerializable' or
'java.io.Serializable' nor does it have a custom field serializer

[ERROR] com.google.gwt.user.client.ui.VerticalPanel has no available
instantiable subtypes. (reached via

How can I workaround this problem, or what approach should I follow ?

Re: Can I build a graphic widget on server side and send it to the client?

2011-01-13 Thread Ben Imp

Widgets are client side things only, so you can't really create them
on the server and send them across the wire.

The simplest solution I can think of would be to take the data in the
DB that you are reading, package it up all nicely in some kind of data
object, and ship it to the client.  The client would then inspect the
data to figure out what it needs to build.

IE 8 and status code error 12030 - 12152

2011-01-13 Thread Khan

We are intermittently getting the StatusCodeException in our GWT
application. Only happens in IE and so far all version of IE shows the
problem. I have searched all over and did not find a thread on GWT
with this issue. Here are all the status code listed on this site.
http://support.microsoft.com/kb/193625. I know that the error is not
what the status code error thrown by IE since other browsers don't
have this issue. I get status code 12152 mostly but also seen others
like 12030, 12031. When using HTTPWatch, it seems that the request wen
nowhere. Please reply to the post if you know how to fix this in GWT
or what the root cause of this. Thank you!

cannot show an icon right next to a link, when having vertical list of link + icons

I want to show an icon right next to a link.
However after spending a lot of time,
could not make it work.

public interface Resources extends ClientBundle {
  @Source(homeIcon.png)
  ImageResource myIcon();
}

and UiBinder:
on the top
ui:with field='res' type='package.of.Resources'/

and the link with icon next to it:

g:FlowPanel
  g:InlineHyperlink .

 g:InlineHyperlink text=Home targetHistoryToken=home /
 g:Image resource='{res.homeIcon}' /

 g:InlineHyperlink .
/g:FlowPanel

the above markup would create a vertical list (similar to  ul li )
the problem s that the image is shown on a line of its own,
not next to the hyperlink. I believe this makes sense because
they are inside a FlowPanel and this is how FlowPanel lays out its
items.

however, i tried to wrap the pair (home link and home icon) in a
container,
but couldnt get the behaviour expected.

does anyone have any idea how I can get this to show correctly ?

what I want is this:

HomeLink Home Icon
Link#2 Icon#2
Link#3 Icon#3

a vertical list, each line having two items
Link + Icon

preferably without using flextable, html table.

thank you

GWT External JARs and use on the Client Side

2011-01-13 Thread Ryan Rathsam

Hi All,

Have a quick question. We're currently trying to use some classes from
an external jar but am running into an error at run time:
[ERROR] [test] - Line 34: No source code is available for type
CLASS; did you forget to inherit a required module?
This error seems to be firing from every place the class is used
except on the server side. The class itself is fairly simple,
implements Serializable and only
has String, Integer attributes w/ the associated getters / setters. Is
there a particular reason that the class is not allowed on the the
client side? Is there some
config / interface that's not setup / implemented?

Any information / help would be much appreciated.

Thanks!

Ryan

VerticalPanel is implemented using a table, which means that it will always 
auto expand to fit its contents.  If you want to ensure that it is 400px, wrap 
each child content in a FlowPanel and set the width of the FlowPanel to 400px 
and overflow to hidden (or scroll).

Hi
 
I need to make the width of the VerticalPanel constant. I have tried setwidth 
and setCellWidth, but both seem not working well.

For example,

VerticalPanel vp = new VerticalPanel();
vp.setCellWidth(this, 400px);
Label textlabel = new textlabel();
textlabel.add(text); --
vp.add(textlabel);

If the text is a string containing various spaces, then the width is able to be 
kept because the wrap is on. Otherwise, if the text is a string without space 
longer than 400px, the string would not wrap. How can I make the width constant 
independent of the string?

Re: Can I build a graphic widget on server side and send it to the client?

2011-01-13 Thread Jack

You could also try to generate the needed HTML on your server and send
it to your client. On your client you could put that HTML into a
custom Widget via setInnerHTML. This custom Widget can overwrite
onBrowserEvent if you need some basic event handling for your
generated HTML.
We did something like this for generating questionnaires on the server
(questionnaires are defined through xml and stored in a db) and
intercepting events whenever a user interacts with a checkbox/
radiobutton/textbox.
We primarily did this because of IE's poor performance. If you use any
other browser then I would also send some sort of custom data object
to the client and use this object to build the UI.

Re: cannot show an icon right next to a link, when having vertical list of link + icons

Thank you,

sorry, I believe I did not ask the right question.
didnt provide the context in which these are going to be used.

this list, is going to be a roll-over list,
meaning upon hovering the background changes.
this can be done in css, and I am getting it to work with css inside
uibinder.
(no need for onHover events etc)

however, whith using CSS Float, they are shown next to eachother,
but upon hover, the entire container contaning that line is not
filled.

for example,
Home homeIcon
the space after the Icon is not filled.

considering these links are in a container, like a box,
upon hover of elements the entire width should be highlighted,
but with float, the area to the right of Icon is not highlighted.

I believe I have to try trial and error with CSS to get them to work.

in the meantime, one GWT related question:

given the ClientBundle and UiBinder below



public interface Resources extends ClientBundle {
  @Source(homeIcon.png)
  ImageResource myIcon();

}

ui:with field='res' type='package.of.Resources'/

with :  g:Image resource='{res.homeIcon}' /
I can get the image,
but is it possible to use this image as a css background ?
for example

.icon {
background-image:url(res.homeIcon);
}

there is an element :

ui:image field= src=/path/to/image

but the path must be explicitly specified.
how can I use ClientBundle, but still use the image in CSS background-
image
instead of  g:Image resource='{res.homeIcon}' /

Thank You

Re: GWT External JARs and use on the Client Side

2011-01-13 Thread Ben Imp

The GWT compiler requires the Java source for any class you want to
use on the client side, as part of its job is to translate that Java
code to JavaScript.

Re: cannot show an icon right next to a link, when having vertical list of link + icons

I got it to work.

I used an HTMLPanel,
and wrapped my g:image in html anchor a.

therefore it appears to be a link and my css selectors for a:hover,
applies to it, and the background color is highlighted upon hover.

Thank You..

still would appreciate some tips on using images defined in the
clientbundle,
inside CSS

ui:with field='res' type='package.of.Resources'/

can we do something similar to this ?

.homeIcon {
background-image:'res.homeIcon';

How to handle com.google.apphosting.api.ApiProxy.CapabilityDisabledException

Hi all.

It would be nice if I could catch CapabilityDisabledException on the client
in the RPC calls onFailure callback methods but it appears it isn't
possible; seems like the exception can only be declared in server code so I
came up with another solution and would like your feedback.

I am thinking about defining a custom exception derived from Throwable and,
sharing it between the client and server. I'd catch
CapabilityDisabledException in my RPC methods and in response I would throw
my custom throwable exception back to the client. In my client's RPC
onFailure callback methods I would catch my custom exception in the
following manner:

   @Override
public void onFailure(Throwable caught) {
try{
throw caught;
}catch (MyCapabilityDisabledException e) {  *===
catch it here**
* // direct the user to a view which explains
that the db is not available and to try again later
}
}catch(IncompatibleRemoteServiceException e){
}catch (InvocationException e){
}catch (Throwable e) {
Window.alert(Severe error!);
}
}

What do you think, do you like the solution or do you have a better one that
you have implemented and successfully tested and used?

Thanks in advance for your feedback.

Re: setwidth and setCellWidth of the VerticalPanel

2011-01-13 Thread John LaBanca

It extends CellPanel, which says that its widgets are contained in the cells
of a table, but you'd have to know to look at the super class and you'd have
to be familiar with how tables handle their contents. So, we should update
the JavaDoc to explain better how table based panels work in practice.

Speed of UI tests with WebDriver

2011-01-13 Thread Kyle Baley

We're starting to make pretty heavy use of UI tests via WebDriver
(using Cucumber and Capybara). The major stumbling block has been the
speed under which they run. Running locally, with the gwt.codesvr
parameter, the tests take the better part of an hour which means no
one will run them locally. On the CI server, they take about half an
hour but they run against a deployed version of the app so it requires
the app to be deployed each time they're run.

Does anyone have any suggestions on speeding the tests up?

I'm about to investigate a couple of options:
1) While working on a feature, we run the UI tests specifically for
that feature only using the gwt.codesvr parameter. When finished, we
can do a full GWT compile, then run all the UI tests locally without
the gwt.codesvr parameter.

2) Try running the UI tests on the CI server using hosted mode. If
this works, it removes the need to deploy the app first. This has
another benefit. Right now, we reset the data before each test using
an API. If it works in hosted mode, we could simplify this by just
replacing the local .bin datastore file before each test. And maybe
even have a series of them with different test data for different
scenarios.

Would appreciate any and all opinions on this along with other
suggestions.

Re: is it possible to develop custom reusable widgets using UiBinder ?

Yes and no. You can create you custom widgets with UiBinder but you have to
resort to mostly relying Composite and HTMLPanel and backing code until
Google ramps up UiBinder. Then, once you components are built, you can reuse
the them just like any other GWT widget in UiBinder by providing its
namespace and import declaration such as:

ui:UiBinder xmlns:ui=urn:ui:com.google.gwt.uibinder
xmlns:g=urn:import:com.google.gwt.user.client.ui
xmlns:dp=urn:import:com.google.gwt.user.datepicker.client
*xmlns:my='urn:import:lmv.com.client.members'* 

Any composite in the lmv.com.client.members package will now be able to be
referenced with the *my* tag.

That's pretty powerful juju if you ask me and the beauty of a component
based framework like GWT.

problem applying CSS classes defined in ClientBundle

I am trying to use CSS classes defined in a ClientBundle
to set the style for my widget.

Unfortunately, the style is not applied.

I use the very same ClientBundle to display an icon, and it works.

I have put the style.css file within the same directory as
MyResources.java clientbundle,
they are in the same package(com.myapp.client.ui.xxx).

this style.css is not included in main html file and is not in webapp
directory.
do I need to put this css file in a webapp folder ?

below is the code:

public interface MyResources extends ClientBundle {

  @Source(style.css)
  Style style();

  @Source(home.png)
  ImageResource homeIcon();

  public interface Style extends CssResource {
  String homeLink();
  }
}

style.css:

.homeLink {
color:red;
font-size:20px;
font-weight:bold;
background-color:green;
}


MyWidget:

public class MyWidget extends Composite  {

FlowPanel panel = new FlowPanel();

private final AppResources resources;


@Inject
public RolloverListWidget(MyResources resources) {
initWidget(panel);
this.resources = resources;

Hyperlink homeLink = new InlineHyperlink(Home, home);

homeLink.setStyleName(this.resources.style().homeLink()); //
link is NOT styled : (

   //
I tried addStyleNames, etc

  //
still didnt work

Image homeIcon = new Image(this.resources.homeIcon()); // I
can see the icon
panel.add(homeLink);
panel.add(homeIcon);
}
}

what I am doing wrong ?
do you know how I can correctly style homeLink using ClientBundle
technique ?

Re: is it possible to develop custom reusable widgets using UiBinder ?

I was thinking pure Java code might have been better,
because everything would be encapsulated in single file, and
properties can be set programmatically.

when developing re-usable components with UiBinder,
do you find yourself using MVP ?

for example having a
- Wdiget Interface
- WidgetImpl java code
- WidgetImpl.ui.xml uibinder file
- and a WidgetPresenter ?

you need to create one:
if you use GWT Eclipse file, it creates one for you.

Re: is it possible to develop custom reusable widgets using UiBinder ?

I use

Widget
Widget.Presenter (nested interface)
WidgetImpl
WidgetImpl.ui.xml

WidgetImpl does not look nice, but at least it's consistent with the MVP 
pattern.  

Having Widget.Presenter nested is also not necessary.

Even though the MVP-based WidgetImpl's are re-usable, I'm not embedding them 
into other UiBinders.  They are created by Gin and plugged into 
AcceptsOneWidget's in Activity.start()

You might have forgotten to call ensureInjected() on your style (the one

This might not suit your team well, but the ability to run plain JUnit is

  Of course at first its good to have a working application, right after

Re: Server Log

2011-01-13 Thread Sripathi Krishnan

The correct way is to override doUnexpectedFailure(Throwable
e)http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/server/rpc/AbstractRemoteServiceServlet.html#doUnexpectedFailure(java.lang.Throwable)in
your custom RPC Servlet. That way you won't have to change GWT's code.

   I just think, I changed the return-value of an existing function and

   the firebug console, I see that my post-request fails, but I

   know...
   But I would need a stacktrace to be logged like method bla doesn't
   support correct return type - TargetInvocationExcaption: Stacktrace
   in such a case. But I don't know how to log those things.
   In development mode, yes, then I see any stacktrace like this. But
   unfortunately there it works and I need to know what goes wrong with

   Is there any way to configure log4j to log those exceptions?

Re: is it possible to develop custom reusable widgets using UiBinder ?

I don't think there is any advantage to having everything in a single file.
In fact it sort of goes against the grain of Java development if you think
about it. At least that's the way I see it. Besides, complex composites
might use composition, using other widgets and composits. Surely these can't
be all in the same file also.

Regarding MVP, no, I don't really use it but I do use parts of its
supporting infrastructure such as GWTEvents, the SimpleEventBus, etc. I also
pay close attention to widget lifecycles which is critical to successful
implementations of widgets that get attached, detached and reattached and so
on and so on.

I guess I just haven't been won over by MVP yet. I find most of the MVP
frameworks I've looked at quite verbose and way too complex for something
that needn't be. Most of what I have seen seems to be code that should
really be hidden deep in the bowels of a framework's internal packaging and
not exposed as a public api. I want to write applications and right now I
just don't see how MVP can make that any easier for me.
