Re: CellTable odd/even row styles

[Thomas Broyer]

The obfuscated names of the CSS classes are based on the return type of the 
ClientBundle method and the method name in the CssResource.
Here, because your SystemStatusResources uses CellTable.Style, it will use 
the same CSS class names as the default resources' style. This means that if 
you use CellTable with the default resources elsewhere in your app, you'll 
have a "conflict".
Declare an interface extending CellTable.Style and 
make SystemStatusResources return that type (return type covariance FTW), 
and now you'll have CSS class names specific to SystemStatusResources.
See http://code.google.com/p/google-web-toolkit/issues/detail?id=6144

Re: Programmatic manipulation of the style elements

[Thomas Broyer]

   
   - use different "style names" (using addStyleName/removeStyleName on a 
   widget) with different "top" values
   - or make the parent an AbsolutePanel
   - or use Element#getStyle().setTop(...), if you don't have a Widget but 
   an Element

What's the problem?

I had the same problem when I upgraded to 2.2 - I resolved it by
correcting the .classpath file in eclipse. There was still an entry
for the 2.1 sdk hanging around (above the 2.2 entry). I removed those
two entries (gwt-dev and gwt-user) and the problem resolved itself...

Programmatic manipulation of the style elements

[Simon M]

I need to position "absolutely" my div object depending of one field of my 
domain object. 

I mean:

if the field of my object is 2, then top should be 25% ( = 0.5 / 2)

if the field is 3, then top should be 16.6% ( = 0.5 / 3)

etc.

Programmatic update of styles is not allowed right now as specified here:
http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html#Runtime_substitution

Does someone have a workaround for that issue ?

Re: Status of IE9 support in GWT

[David Chandler]

We've started the release process for milestone 1, which has some but not
all of IE9 support. From this point, it usually takes 3-6 weeks to get
through the milestones, RCs, etc.

Re: CellTable odd/even row styles

[Yaakov Chaikin]

Ok, I did that and it's still showing the default styles.

To be clear, here is what I did:

SystemStatusResources.java
-
// import statements
...

public interface SystemStatusResources extends CellTable.Resources
{
   @Source ({CellTable.Style.DEFAULT_CSS, "systemStatus.css"})
   CellTable.Style getStyle();
}
-

The 'systemStatus.css' file sits in the same package as the
SystemStatusResources.java and looks like this:
-
.cellTableEvenRow {
   background: #ff;
}

.cellTableOddRow {
   background: #ff;
}

.cellTableOddRowCell {
   border: selectionBorderWidth solid #ff;
}

.cellTableEvenRowCell {
border: selectionBorderWidth solid #ff;
}
-

Inside the SystemStatusListView.java:
-
...
...
CellTable.Resources resources = GWT.create(SystemStatusResources.class);
CellTable> dataTable = new CellTable>(0, resources);
...
-

The end result is that the same default color shows up for the odd rows.

Any ideas what I am doing wrong?

Thanks,
Yaakov.

Re: How to compile selectively or avoid compilation of inheriting/implementing classes?

[Chris Conroy]

GWT speculatively parses anything you put on the source path. If you don't
want something to be included in your module, you need to explicitly say so
in your .gwt.xml.

Re: Is there a way to workaround GWT compiler/serializer/linker issue?

[Andreas Horst]

Do you use that abstract base class as a RPC parameter? If so, *of
course*GWT has to look for and try to compile all sub classes and
implementations
*since* they might get used in a RPC and hence need to be serializable and
compilable.

To avoid this you can either:
- refactor your RPC to use only the concrete types

*or* if you rely on using abstract classes or interfaces in RPC:
- you might want to configure your sub classes' packages to be part of a
module's client packages, so that the GWT compiler finds them (your "No
source found..." error indicates that this is not the case).

I personnaly think your problem is not the behaviour of the GWT compiler but
your project setup regarding separation into modules. Hope this can help
you.

Is there a way to workaround GWT compiler/serializer/linker issue?

[KD]

Lets say I have package : com.mycom.model

It has following classes

com.mycom.model.PlatformMessage (an interface)

com.mycom.model.AbstractMessage (an abstract class that implements
PlatformMessage)

com.mycom.model.QueryMessage (a concrete implementation of
AbstractMessage)

Now there is another package: com.mycom.app

It has the following class...

com.mycom.app.StreamMessage (a concrete implementation of
AbstractMessage)

ONLY com.mycom.model a GWT module.

Now when I compile com.mycom.model, why does it need to go and look
for all implementations of that abstract class AbstractMessage in
OTHER packages (as I later find with many No Source found..."
errors)?

It seems RPC serializer is trying to serialize/compile all classes
that IMPLEMENT an abstract class in my gwt module.

Is there way to workaround this?

Re: How to compile selectively or avoid compilation of inheriting/implementing classes?

[KD]

Ok let me rephrase this.
Say, there is an abstract class com.model.AbstractMessage and one of
its implementation are in same package called
com.model.ConcreteMessage.

Now another class in another package also implements the
com.model.AbstractMessage, lets call it com.api.ChangeMessage

Now when I compile the GWT module "com.model" why does it need to go
look at all implementations of the abstract class
com.model.AbstractModel in other packages? com.model is THE BASE
package, everything else extends it. What if I just want to make that
a GWT module and nothing else.

Is there is the way to stop it?

Re: One Session(HTTP) for multiple GWT-Modules?

[Juan Pablo Gardella]

But will it then be possible to make in each module a gwt-rpc-call
which checks, if the user is logged-in?

Yes, is possible.

Will the Session be the same, or will each call (from different
modules) deliver a different session-id?

I handle this with Spring security, is transparent. If you don't use Spring
security search other threads that explain this.

And what happens, if the users browser has cookies disabled? Is there
a way to rewrite the url like in JSP or Servlets?

I handle this with Spring security, is transparent.

Re: Development Mode quit unexpectedly while using libjava.jnilib plugin

The problem seems to have resolved itself more or less. I'm not sure exactly
what I did but the only thing I recall changing was including
gwt-servlet.jar into my class path.

GWT breaks on Java OSX 10.6 Update 4

[hellomaylo]

Anyone else seeing this?  When I apply the current Java OSX 10.6
Update 4, all of my GWT apps run from Eclipse crash java.  This
applies to either Eclipse 32 or 64bit.  My colleague and I found this
when we both got new MacBook Pros, I updated and he didn't, I was
broken and he wasn't.  Since I haven't found a way to rollback the
updates, I reinstalled OSX and life is good again.

Development Mode quit unexpectedly while using libjava.jnilib plugin

[Nick]

Just got a brand new mac book pro for work.
Installed the latest JDK (1.6.0_24), App Engine SDK(1.4.2), and
GWT(2.2.0)
Using intellij, created a new project and configured everything the
same way I've been doing for the last 6 months with no problems. Tried
to debug my GWT application and it crashed. Restarted my computer
thinking all the new SDKs might be worth a restart. It worked once and
then started crashing again. I think the new JDK is what broke this
cause I have an almost identical set up at home but I'm using and
older JDK. Please help me resolve this. Thanks.

ArrayList, size not changing when item is removed

[Sockmonster]

Hi, I'm having a problem with an ArrayList in GWT. Adding items to the
ArrayList works as expected (ie size increments by the number of items
added). However, when I remove an item from the list the size does not
decrement. For example if I add 5 items to a list and then remove an
item, the size remains 5.

I assume this is because the ArrayList is actually implemented using
an Array (as in Java) that doubles in size when it's capacity is
reached, but doesn't shrink when items are removed. But unlike Java,
calling size() returns the size of the array rather than the number of
elements it contains?

Has anyone else encountered this? Am I far off the mark?

Many thanks.

GWT compiler/serializer/linker issue?

[KD]

Lets say I have a class

com.mycom.app.AbstractMessage

There is another class in

com.mycom.model.QueryResponse

QueryResponse extends AbstractMessage and notice they are in different
pacakges

com.mycom.model is a GWT Module and in the module XML

When I compile model there are errors. However when I try to use
QueryReponse in another GWT module, I get runtime errors

"No source code is available for type com.mycom.app.AbstractMessage;
did you forget to inherit a required module"

This lends me to believe that AbstractMessage was not compiled/
compiled right to begin understandably because I DO NOT WANT to have
"app" package be a GWT module

In other words, I only want to compile all classes in "model" and not
any super classes. How can I tell the GWT compiler/rpc/linker/
serializer etc not to do so?

I am doing this a source environment where we have a lot of packages,
most of them depend on MODEL only and I DO NOT want to make a GWT
module out of every package, just so it compiles.

Thought anyone?

Status of IE9 support in GWT

[David Chandler]

In keeping with the GWT philosophy of making it possible to write
no-compromise AJAX in any modern browser, GWT 2.3 (in progress) will support
IE9. We're adding a new user.agent property "ie9" and the notion of fallback
properties, so any browser-specific bindings not yet implemented in ie9 will
fall back to ie8 and show a compile-time warning that a fallback impl was
used.

In the mean time, you can tell IE9 to behave as IE8 by inserting the
following in the head section of your GWT host page:


Assuming that IE continues to maintain backward compatibility, you may want
to insert the equivalent tag for IE9 once GWT 2.3 ships in order to make
your app somewhat future-proof for future IE versions. For more information
on document compatibility in Internet Explorer, see
http://msdn.microsoft.com/en-us/library/cc288325(VS.85).aspx

The IE9 dev mode issue reported back in Dec is fixed in GWT 2.2.0:
http://googlewebtoolkit.blogspot.com/2010/12/support-for-gwt-dev-mode-in-ie-9.html

You can follow the status of known IE9 issues here:

Re: GWT app only displays a blank page when run in ie9

[TBirch]

I have been able to get my sites to work by changing the setting in
ie9 to "internet explorer 9 compatibility view". What do I need to do
to the code for my sites for them to work in normal ie9 view?

GWT app only displays a blank page when run in ie9

[TBirch]

I downloaded ie 9 today to my windows vista pc. All applications that
I have that run fine under ie8, firefox, chrome, etc. only show a
blank page in ie9. I've searched but do not see any posts noting
problems running in ie9.

Re: One Session(HTTP) for multiple GWT-Modules?

[Johannes Stein]

Yes, thats right.
But will it then be possible to make in each module a gwt-rpc-call
which checks, if the user is logged-in?
Will the Session be the same, or will each call (from different
modules) deliver a different session-id?
And what happens, if the users browser has cookies disabled? Is there
a way to rewrite the url like in JSP or Servlets?

Re: ValueProxy containing EntityProxy

[fclaeys]

Thank for your answer Jake.

I try with with(...) But it does not work.

I think with(...) is useful for relationships between EntityProxies but not 
for ValueProxy because ValueProxy haven't relationships.

One Session(HTTP) for multiple GWT-Modules?

[Johannes Stein]

hello,

im implementing a little online-game with gwt.
this game contains two modules - one ui for the game itself and a
seperate user-area.
if a user is logged-in into the user-area he should be able to write
comments etc. in the game-gui (the other module).
is it possible to share a http-session between the modules? what could
be a solution?

thanks for any help!

Re: CellTable odd/even row styles

[Jeff Larsen]

You'll notice in CellTable there are some inner classes. One of those 
classes is Style and the other is Resources. 

Style is the class that has the styles which are used, Resources maps that 
class to its css value.

Inside Style you'll notice two methods called cellTableEvenRow and 
cellTableOddRow. Those are the two classes you're going to care about. 

If you want completely different styles, you can implement your own style 
sheet (just copy the Style.css from com.google.gwt.cellview.client package 
and change the values inside the classes). Or if you just want to override 
the alternating views you can do something like.


public interface MyResources extends CellTable.Resources{

@Source({CellTable.Style.DEFAULT_CSS, "MyCssFile.css"})
CellTable.Style getStyle();
}


and in MyCssFile.css just implement .cellTableEvenRow and cellTableOddRow.

Then make sure to pass in MyResources into the constructor of the CellTable 
and you should have the styles you're looking for.

Re: CellTable odd/even row styles

[Raphaël Brugier]

The good way to override the style of a cellTable is to pass a Ressource to 
the constructor.
See the Expense 
example

Re: Proxy hell

[jhulford]

I'm not familiar w/ a jetty setup, so I suppose you could have done
something in your global configurations, but you have no servlet-
mapping set up in the web.xml to handle the base URI for your web app
(which is presumably deployed to the proxytest path?).   The
DefaultServlet is then what will be handling a request to /proxytest
request due to you not having a specific servlet set up for the
request path and all that is going to do is look for a welcome file
since you don't have any actual file specified in your request path.

It also looks like you don't have a Test.html, set up under the web
app either, or it's in the wrong directory, otherwise the jetty
DefaultServlet should have returned that.

What file are you expecting to be returned or what servlet invoked by
a request to http://localhost:8080/proxytest?

CellTable odd/even row styles

[Yaakov]

Hi,

Is there a way to override the default odd/even row styles in a
CellTable?

I've tried to do this through CSS rules, but it seems like something
deep down in the code is overriding it or wiping my style altogether
to be more accurate.

I tried this (keep in mind that I have a SimplePanel wrapping the
table with a style applied to the SimplePanel called
'tablePlaceholder');

.tablePlaceholder thead tr {
background: none repeat scroll 0 0 #FF !important;
}

.tablePlaceholder thead tr td {
border: 2px solid #FF;
}

When I use Firebug to see what styles got applied, those styles are
gone, something wiped those styles and replaced it with:
on :
background: none repeat scroll 0 0 #F3F7FB;

on a :
border: 2px solid #F3F7FB;

Any help would be appreciated!

-Yaakov.

Re: Stop keyboard events

[Achilli]

Only if u kill the user before he does that!  :)

But if u are satisfied with filtering what's being pressed you can do
like this (example uses uibinding syntax):

@UiHandler("inputValue")
void onInputValueInserted(KeyUpEvent e) {
if(!inputValue.getText().isEmpty()) {
if(!inputValue.getText().matches("[1-9]\\d{0,}")) { // I want to
filter out what's not a number and those numbers starting with 0
inputValue.setText(inputValue.getText().subSequence(0,
inputValue.getText().length() - 1).toString()); // remove the last
char
}
}
}

I have my code like this

 service = (SessoesAsync) GWT.create(Sessoes.class);
 ServiceDefTarget endpoint = (ServiceDefTarget) service;
 endpoint.setServiceEntryPoint(GWT.getModuleBaseURL() + 
"sessoes");

final AsyncCallback > callback = new
AsyncCallback >(){

@Override
public void onFailure(Throwable caught) 
{
Window.alert("Communication 
failed");
 
Window.alert(caught.getLocalizedMessage());

}

@Override
public void onSuccess(ArrayList 
 result) {
  if (result != null) {
  for (int i = 0; i < 
result.size(); i++) {

System.out.println("\t"+ i+"-" + result.get(i));

}
} else {
Window.alert("Account Empty");
}

}};


public interface SessoesAsync{

  public void  login(String Id,String Pass,
AsyncCallback> callback) ;
}



@RemoteServiceRelativePath("sessoes")
public interface Sessoes extends RemoteService{

  public ArrayList  login(String Id,String Pass) ;
}


public class SessoesImpl extends RemoteServiceServlet implements
Sessoes{

SpreadsheetService service = new SpreadsheetService("SpreadSheet
demo");
ArrayList lista=null;
@Override
public ArrayList  login(String Id, String Pass)
{Mycode(Doesnt really matter for this)}


}


And my Web.xml is like that

You don't need an older appengine/gwt. You need an older JDK.

Ah I read it wrong, yes... The JDK is also up to date. Is it possible
to downgrade?

Yep, everything is up to date. Is there a repository where I can get
older appengine versions?

DevMode server in AppEngine projects stops immediately after starting the server

[Jambi]

Hey guys,

I got a strange behaviour with my AppEngine projects. The Server in
DevMode stops 2-4 seconds right after starting the Server. But there´s
no exception or any error message. I´m pretty sure that it´s not an
issue with my own project because the same failure occurs when I
create a new GWT project with the sample app. One other weird thing is
that it worked one time in the last hours. The project is working fine
when it´s hostet on AppEngine.

the console is giving me this:

2011-03-16 16:33:53.675 java[4580:a07] [Java CocoaComponent
compatibility mode]: Enabled
2011-03-16 16:33:53.693 java[4580:a07] [Java CocoaComponent

Successfully processed /Users/michael/Documents/Development/workspace/
test/war/WEB-INF/web.xml
The server is running at http://localhost:/

---
After this the server stops...
Any Idea?

Re: java.lang.ClassCastException: org.mortbay.jetty.nio.SelectChannelConnector$RetryContinuation cannot be cast to org.mortbay.util.ajax.Continuation

[Juan Pablo Gardella]

I think the problem is here:

javax.management.ObjectName is a restricted class. Please see the Google
 App Engine developer's guide for more details.

This class isn't in
http://code.google.com/appengine/docs/java/jrewhitelist.html

I suppose you can't use that. ActiveMQ use this class.

…and use the -noserver mode of the DevMode: 
http://code.google.com/webtoolkit/doc/latest/DevGuideCompilingAndDebugging.html#How_do_I_use_my_own_server_in_development_mode_instead_of_GWT's
 
I'd go with option #3 if possible, and option #1 otherwise.

Re: Development mode and Requests(Ajax)

[Sachin Dole]

You are being blocked by sop. Single origin policy.

To go around u have 3 options.
1. Setup a redirect servlet in ur UI app that fetches remote data and serves
to client.
2. Write native js in gwt to dynamically write out a script tag on your
HTML. This is like jsonp.
3. Deploy the online app - ur data source - on your dev environment.

Re: ValueProxy containing EntityProxy

[Martín]

i have the same problem, but the solution that i have found is:

// This method goes on the entity
public String getValue(){
   return this.pk.getValue(); // the primary key is my ValueProxy
variable
}

and delare:

public String getValue()
on the proxy entity

i´m very new on this framework, if someone have a better answer,
please show us.

Development mode and Requests(Ajax)

[Kari]

Hey all,

I am writing a UI which makes asynchronous calls to a server. That
server is actually the server on which the UI will be deployed.
However, since I am in dev-mode my domain is 127.0.0.1: and the
requests are sent to another domain (online.) Unfortunately, I am
getting the "Access-Control-Allow-Origin" message and no date.

My guess is that I am missing something since this sounds like a
typical case but for some reason I haven't found an elegant solution.
I thought that something like that would be already part of GWT. I
have found about "add-linker" but it didn't seem to work. In the very
worst case, how could I do everything locally; would the server code
and client code have to be on the same port, and how could that be
done if any different from being on a different domain?

Thanks all

Future of AbstractScrollTable in Incubator and EnterpriseCellTable functionality

[Bappy]

Hi there,

I currently use AbstractScrollTable from the incubator. I'm aware that
the incubator won't be maintained in future so obviously I'd like to
move away from using it in my implementation. I've heard this
EnterpriseCellTable will appear at some point, will this provide the
same functionality? Basically I need a scrolling table widget that
supports fixed headers, sorting etc (not too fussed about paging!).
Before I start implementing this myself I was wondering if this
EnterpriseCellTable will provide this functionality.

Cheers!

Bappy

You can generate an URL to make the report and use

How to automatically download image to client from server when button clicked

[azuniga]

I am having the user click a button that will generate a report on the
server side. The report has embedded charts and graphs but since the
report is generated server side with BIRT libraries, when I return the
report as an HTML string, the images aren't displayed. What I'm trying
to do is have those images downloaded to the user's machine
automatically and then adding an image widget to the panel to display
the charts and graphs. Is there some sample code I can use to do this?
I have the server side servlet code I found from and example and
modified it for my code. I am missing the client side code. Can anyone
help? Also, I'd appreciate any suggestions or advice if I'm not doing
this correctly or if there's some better way to do this.

Server side:
public class FileServlet extends HttpServlet {
protected void doGet(HttpServletRequest req, HttpServletResponse
resp) throws
ServletException, IOException {

// set the responses content type
resp.setContentType("image/svg+xml");

// set the header for the response
resp.setHeader("Content-Disposition", "attachment;
filename=image.svg");

// get the output writer
PrintWriter out = resp.getWriter();

// display a simple message
out.println("This is the output content");
out.println("Probably something dynamic should go in here");

}
}

Client Side:?

Re: empty "ghost" place token getting created

[Christopher]

I figured it out - I was using a Hyperlink widget without having set
the targetHistoryToken. I also had a click handler for the widget that
attempted going to the place; which it did. However because there was
no targetHistoryToken the default place was being navigated to after.

My link now looks like:

ValueProxy containing EntityProxy

[fclaeys]

Hello,

I use RequestFactory for communication with the server, in one 
case, I have to call the request with a ValueProxy containing some 
EntityProxy, but when I retrieve the object corresponding to the ValueProxy 
on the server, the fields for EntityProxy are null.

Is it possible to use ValueProxy this way?


Thanks in advance.

Re: Compiled GWT JS size > handwritten JS size?

[ss.require]

Thanks for replys. Actually, I'm developing an application with a
design that is the same as Facebook has. This design implies that all
pages in the app are loaded by AJAX not by a traditional url-site
navigation and the application should have js-file for every
pagelet(some unique area of functionality) that is lazily loaded
during site navigation. At the beginning I thought to create a single
module and load additional pagelets through "code splitting" feature.
But now I think this is not the case for GWT due to 2 reasons:
1)Pagelet usually has a simple functionality(10-20 lines of JS) but an
exclusive fragment that GWT generates for such a pagelet is much
larger about 15Kb due to JRE's base and maybe something else.
2)I think a compiler will not be able to generate clever 100 js small
files as I can by handwritten js-files.
3)Every pagelet should be loaded from a single module. It's also a
problem how to navigate to 100 pagelets from a single module.

The speed of page's loading is very important, every pagelet should be
loaded instantly, I can't wait while a big js load.

So now I think to use a single GWT module for some very interactive
components(pagelets) but use simple handwritten js for simple pagelets
due to gwt's performance overhead.

What do you think about that? Any ideas?
