Hi,
I have thought about similar solutions too and your example is very
interesting.

Re: Two generator questions

[PhilBeaudoin]

Yeah, well... Method injection didn't work either, the method just
never got called (as expected...)

I finally was able to make it work using the technique you proposed by
initializing the generated classes after the injector is created.

Just to give a bit more details to anybody else interested in this...

Here is how you define a configuration property in your
project.gwt.xml:
  
  

Here is how you access this property in your generator:
  String ginjectorClassName =
ctx.getPropertyOracle().getConfigurationProperty("gin.injector").getValues().get(0);

Now if you want an injector in the source code you generate you do:
  writer.println( ginjectorClassName + " injector = GWT.create(" +
ginjectorClassName + ".class);"  );


Thanks again Gal. This is a neat trick!

Re: Two generator questions

[PhilBeaudoin]

One last update:
I don't think its a good idea to GWT.create() the ginjector multiple
times. I got rid of this by creating it once in a static field in my
entry point class, and then accessing that field within my generated
class. This brings me to another question:

To find the name of the entry point class, I had to create a
configuration property. Is there a way, within a generator, to access
the entry point class defined in the module:

How do I use GWT-Ext 2.0.6 widgets with GWT 2.0?

[Dan]

Hi all,

I am trying to find a tutorial on how to use GWT-Ext 2.0.6 widgets in
a GWT 2.0 project.
Only found a couple, but if I follow them and try to include the
widgets here http://www.gwt-ext.com/demo/#multipleFieldForm I always
get an error

com.google.gwt.core.client.JavaScriptException: (TypeError): Cannot
read property 'StatusBar' of undefined stack: TypeError: Cannot read
property 'StatusBar' of undefined.

Is there any step by step guide to integrate GWT-Ext 2.0.6 with GWT
2.0?

The results returned are GWT-Ext, EXT-GWT and Ext all mixed together,
so can't see a specific one.

Thanks, Dan

In fact this solution is very clean. Use uibinder as much as you can.

Re: DockLayoutPanel blank

[Jaan]

Layout panels must be added into to the RootLayoutPanel, not
RootPanel.

So change
 RootPanel.get("zodiacEntryPoint").add(lol);
to
 RootLayoutPanel.get("zodiacEntryPoint").add(lol);

and everything should work.

We do not use GWT-RPC in our apps, but I've built a proto recently (to
get a coworker started on a new project) that uses GWT-RPC (and I'll
probably use it in another new app), and I've put the interfaces in a
"shared" package, along with the classes that are passed through GWT-
RPC.

Re: update widget on panel

[JD]

I just tried something with interesting results.

In the updateButton anonymous clickhandler class, I tried a
Window.alert attempting to output the index of the widget object w on
its containing panel. It came back -1, meaning w is not to be found.
Does this have something to do with how anonymous inner classes use
the external classes objects? Maybe a clone or something? If so, how
can i handle this?

thanks.

Re: How do I use GWT-Ext 2.0.6 widgets with GWT 2.0?

[Dan]

Yes, I know it's dead... But at work they have found that particular
date and time pickers that they like and were wondering if it's still
possible to include just those two widgets in the project.

I don't mind doing some research myself as long as somebody can
confirm it's still possible to use GWT-Ext in a GWT 2.0 application?

Thanks for your answer anyway :)

Re: DockLayoutPanel blank

[zggame]

A small typo.   I think RootLayoutPanel only has get(), not get(String
element).  So there can only be one RootLayoutPanel, which anchors on
.  Generally, I found it is better not to mix  *layoutPanels and
old panels.  Things are easily screwed up.  I once put a simplePanel
in a DockLayoutPanel and that one disappears from time to time.  I
change the simplePanel to LayoutPanel and it works fine since.

Re: gwt-dispatch, gwt-presenter, mvp4g

I second that idea.  I start to really understand the gwt-presenter by
reading its code.  It is actually not that complicated and teach me
some really nice lessons.  And you also see a few short-coming of it.
It is open-source under BSD.  So you can do whatever to fit it for
your purpose.

Re: gwt-dispatch, gwt-presenter, mvp4g

[Jamie Gennis]

I'll take this opportunity to insert a shameless plug for
gwt-remote-action as an
alternative to gwt-dispatch.  The idea behind gwt-remote-action is that it
enables use of the command pattern using the same RPC interface as
traditional GWT RPC.  This means you don't have to build your app from the
ground up with the command pattern in mind, but rather you can just use
normal GWT RPC and then augment it later when you need caching,
transactions, undo, or any other command pattern goodness.

You can also check out
gwt-remote-action-extension
for
a library than enables the use of Gilead with gwt-remote-action as well as a
demo app.

Best,
Jamie

JsonpRequestBuilder and JsArray

[A. Kong]

Hi, all,

I am still encountering some problem with JsonpRequestBuilder. I hope
anyone may point out what's why with my code.

Basically I have a json server which emits the following data:



[{'Article': {'title': 'Main test2010-03-17 19:21:54.865390'}},
{'Article': {'title': 'Main test2010-03-17 19:25:19.773520'}}]




On GWT front, I have




public void onModuleLoad() {

JsonpRequestBuilder requestBuilder = new JsonpRequestBuilder();
requestBuilder.setCallbackParam("callback");
requestBuilder.requestObject(SERVER_URL, new
MyTestRequestCallback());

}

class MyTestRequestCallback implements
AsyncCallback> {

@Override
public void onFailure(Throwable caught) {
Window.alert("Failed to send the message: " + 
caught.getMessage() +
" " + caught.getStackTrace()[0].toString());
}

@Override
public void onSuccess(JsArray result) {
Window.alert(result.get(0).getTitle());
}




And here is my definition of Article class



public class Article extends JavaScriptObject {

protected Article() {};

public final native String getTitle() /*-{ return this.title; }-*/;

}



The problem is: the result of "result.get(0).getTitle()" is always
null.

Setting the break point in the onSuccess() does not help much. The
content of the valuable is a 'ref n' where n is a number (in the debug
perspective of eclipse)

My questions are
1) What is the likely cause of the failure of capturing 'title'? Any
obvious error in my code?

2) I tried to debug in firebug, but failed to locate where the parsing
of json occurs. When I compiled the project, I used "output style" =
detailed. When I search for ".title" i could not find anything.
Shouldn't the native code be captured in the generated gwt code
intact?

Re: MVP related question

Good point to place any class that are passed through wire to shared. And I
think its natural
to put RPC interfaces  there too.

Re: Two generator questions

[Gal Dolber]

You don't need to do that, you can just put a static instance of the
Injector on the injector interface.

Re: Two generator questions

[Philippe Beaudoin]

Yes. Much simpler indeed. Would you believe I didn't even know you could
have static instances attached to interfaces... I'm still relatively new to
Java. :)

Your code does the JS equivalent to "the_array[0].title" while given
the data snippet you gave it should be the_array[0].Article.title.

There's no "JSON parsing" with "JSON-P" as it's just JavaScript, not
JSON at all. IMO, you should find ".title" but maybe it has been
rewritten as the_obj["title"], with the String "interned" in a
"global" variable. Search for ".alert" instead ;-)

Re: JsonpRequestBuilder and JsArray

[A. Kong]

Hi, Thomas,

Thanks very much for the quick reply!

I am away from the workstation where the work is, so I cannot give
your suggestion a go yet.

But I have a question about the remedy you suggested, namely to access
the 'title' field using '_array[0].Article.title'

In my case, I would have expected GWT to be able to understand the
JSON "[]" representation as an array. GWT should be able to dispatch
each individual element in the array to Article class, which will use
native methods to map out individual attributes. That's why I assume
"this" in "this.title" correspond to "Aritcle:{...}"

Now let's say I changed the native code to 'array[0].Article.title'.
Then what will happen if i use another server interface that returns a
single Article? The callback will now become AsyncCallback
and array is not present in the json data.

I hope I did not sound too confusing. Maybe there is a gap in how I
understand the JNI works

Cheers

it values from in the line  food.getFoodFans().add(getKey()); Could
some please explain. Thanks.

[Jim]

I want to create a Google Application Project from Java Code instead
of IDE. How can I do it? Is Google Eclipse Plugin for GWT open source?
I know how to create a Java project through Java code like:

final IProjectDescription description
= project.getDescription();
description.setNatureIds(new String[] 
{JavaCore.NATURE_ID,
ProjectNature.NATURE_ID});
description.setLocation(null);  //default 
location


I do appreciate it if you can show me how to download the source code
if it is open source and how to use Google Eclipse Plugin in java
code.

what event does the PopupPanel use to autohide?

[Tristan]

Hi,

I'm trying to automate my testing via Selenium. When I do it myself by
hand, the popup panel hides when I click outside of it (ie.. it works
as expected), however when I use selenium.click or clickAt or
fireEvent blur or mouseDownAt, etc... i cannot get the popup panel to
hide and my test fails. Is there a specific event that PopupPanel
listens to? I'm using selenium rc and safari browser.

Cheers!

Tristan

Re: GWT 1.3 and firefox 3.6

[Roland]

Yes, after paying more attenition, discovered that
$doc.getBoxObjectFor is not a function was thrown.

Got it fixed following this:

http://www.mail-archive.com/google-web-toolkit@googlegroups.com/msg36310.html

But I'd like to know whether this is a failure only for gwt's earlier
versions or not?

gwt for a servlet / jsp guy....

[JayUnit100]

Hi guys I'm trying to wrap my head around GWT.  I want to bundle
it into a simple FrontMan based web app, with a controller and some
jsps.

However, I'm realizing that maybe I need to "think"  a little
differently with GWT.  That is, so much stuff about web app
development that we take for granted is BASED on the idea that there
is a client and a server.  With GWT, I'm not sure what variables I
should put in  my "client" classes, and what I should do on the server
side.  Also I dont know where to handle the "M" in MVC.  Im not
interested in downloading an immature GWT-MVC extension framework ---
Id rather work with GWT as is, and create my own MVC.

Any thoughts on these issues ?

[Newbie] "java.net.SocketException: Invalid argument" when running devmode

[Chihab Otmani]

Hi all,

I've got the following errors when running the development mode code
server as described in this tutorial: 
http://code.google.com/webtoolkit/doc/latest/tutorial/create.html,
either using eclipse or webAppcreator ant.

When using Eclipse, the following message is displayed in the
console :
"Could not connect to remote UI listening at localhost:52134. Using
default UI instead."
The GWT development Mode window is displayed. According to the Web
Server tab, AppEngine seems to be started. The Development mode tab
shows a Communications error -- exception SocketException the detailed
trace is :

* Java version "1.6.0_16" (Java HotSpot(TM) 64-Bit Server VM (build

GWT + SPRING SECURITY

[larry]

Hi all.
I'm new here. I'm currently using gwt 1.7 gwt-ext 2.0.x, spring 2.5
and spring-security 2.0.4. I met a problem that I have tried to get a
solution for two days with no answer yet. The problem is that any
unprotected gwt pages return blank with an error message "Line: 2
Char: 1 Error: Syntax error Code:0". But if user was authenticated and
redirect to those pages they return fine.
I know this is because of spring-security added on. What I did is
trying to create a gwt login form to replace my old JSP login page.
But this gwt login page is returned with above error. I changed my
security configuration settings in many ways but none of them work.
Here is my configuration:

http://www.springframework.org/schema/
security"
xmlns:beans="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
   http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security-2.0.4.xsd";>



  
  
 


 
  












..

I even just put a "Hello word" in my Login page it still doesn't work.

Please if anyone has the experience of this let me know. Thanks

Tree and Composites

[Talmge]

When I add a simple Widget to a tree (Such as a checkbox or call
addItem with a string) I can select the item -- that is, if I click on
it the blue background appears around the text showing me that I
selected that node in the tree.

With other widgets such as labels or composites that blue background
does not appear around the selected node, and I have no way of
visually knowing it was selected. I imagine this is me not
understanding how the click events are not being handled and was
wondering if someone could indicate the right way to accomplish this?

public class MyTest implements EntryPoint
{

public void onModuleLoad()
{


Tree editTree = new Tree();
editTree.setWidth("98%");

TreeItem treeRoot = new TreeItem("Tree Root");

treeRoot.addItem("I can Be Selected");
treeRoot.addItem(new Label("I can't Be selected"));
treeRoot.addItem(new CheckBox("I am a checkbox, and I can be
selected as well."));
treeRoot.addItem(new SomeComposite());

editTree.addItem(treeRoot);

RootLayoutPanel.get().add(editTree);

}


public class SomeComposite extends Composite
{

public SomeComposite()
{

super.initWidget(new HTML("I am a composite and I can't 
be selected
either."));

}

}
}

Problems with Eclipse Plugin

[moe]

Hey,

after installing the GWT Plugin, I want to change the directory of
Eclipse - it was in my downloads folder.
But now the Google SDKs aren't found any more by Eclipse.
To change the directory first and then install didn't work either.
I use Mac OS X 10.6, Eclipse 3.5.2 (64 bit) and GWT 2.0.3.

Thanks for any help!

HorizontalSplitPanel children

[TM]

Hi, I'm having quite a lot of trouble with panels and layouts. My app
currently consists of a DockPanel containing a HorizontalSplitPanel,
which in turn contains various widgets either side of the split.

However, when the HorizontalSplitPanel splitter is moved nothing
happens to the sizes of the child widgets. I have set their widths to
100%, so I was expecting them to fill the available space.

I already have added a custom resize handler to make the DockPanel
fill the client area when the browser is resized. Would I have to do
something similar for every other panel that might resize?

Thanks
