DoubleBox cell decimals positions formatting
I have this in my uiBinder: e:ValueBoxEditorDecorator ui:field=importoEditor e:valuebox g:DoubleBox / /e:valuebox /e:ValueBoxEditorDecorator Declared as @UiField ValueBoxEditorDecoratorDouble importoEditor; in my code. It behaves correctly: 50 displays as 50.0. Now I want to display it as 50.00, since it is a currency euro value.

DoubleBox is simply a ValueBox using DoubleParser/DoubleRenderer; and DoubleRenderer uses NumberFormat.getDecimalFormat().

Re: Generating XML
Thank you both for your assistance. I will attempt to use the XStream library first, but the XML is not intended to to be parsed and objects re-built from it; rather the information will be used by another system. Thus, it depends how much I can customise the XStream output to suit the desired XML format. Karim, upon investigating the JAXB framework I discovered that this is the standard practise in the company I work for(student internship, hence why I was unaware) but as I have stated the simplicity of the objects and resulting XML may suit a simpler method. I had never considered manipulating the toString methods to my advantage, so if XStream does not suit then this is the path I will take.

How to center element containing CellTable?
I'm trying to center an element that contains a CellTable. The actual
centering logic works okay, but I'm having problems with all those
attaching/detaching events. Basically, I'm doing this in my container
widget:
@Override
public void onLoad() {
super.onLoad();
center();
}
However, it seems that `onLoad` on the container does not mean that all
children have loaded, so... the actual centering routine is called to
early and Element.getOffsetWidth/getOffsetHeight are both returning 0.
This results in the container being displayed with the left upper corner
in the center of the screen.
Same thing happens if I use an AttachEvent.Handler on the CellTable.
So... is there any event on CellTable, or on Widget or whatever that
allows me to trigger an action when the DOM subtree has been attached to
the DOM?
Thanks in advance.

Re: CellTable + Editor displaying only those rows based on a flag in the bean
You will probably use an AbstractDataProvider instance to fill the
CellTable. You have to create a helper method which retrieves the list of
beans based on the flag and sets it in the AbstractDataProvider (or
ListDataProvider).
Something like this:
final ListDataProviderUser dataProvider = new ListDataProviderUser();
ListUser listToDisplay = new ArrayListUser();
for (User user: userList) {
if (user.isActive())
listToDisplay.add(user);
}
dataProvider.setList(listToDisplay);
dataProvider.addDataDisplay(cellList);

Re: CellTable custom footer
Hi John I do have a question regarding redrawing the entire DataGrid/CellTable when new data is pushed in. I tried to implement a SearchTextBoxes in the ColumnHeader for filtering the data which is displayed in the CellTable. As soon as I type a character into the SearchTextBox in one of the column headers I filter the ListDataProvider and the CellTable is refreshed. However the refresh/redraw of the celltable causes the SearchTextBox input to lose its focus and currently in GWT 2.3 there is no way to specify that the SearchTextBox gets the focus back which leads to painful user experience (the user has to click into the SearchTextBox again to type in the next character). I have posted this question in Stackoverflow ( http://stackoverflow.com/questions/6422896/celltable-with-custom-header-containing-searchbox-and-focus-problem) but got no responses. https://lh5.googleusercontent.com/-QSUJ0kixSwc/TlIhZUqdDGI/AFs/o48fsjiC5Yc/celltable_search_header.png I solved this problem by creating another table above my CellTable, putting the Searchboxes there and trying to align them to my CellTable headers. But that doesn't seem to be a really good way to do it (check screenshot). Can this problem be solved with the new CellWidget API in 2.4 ? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

We have refreshed the view because instead of calling

By calling batchTable.setRowData() we are simply more directly
targeting both the display and only the row that has changed. (Rather
than all visible rows by calling refresh().)
As far as I can tell from the system, the DataProviders have no
knowledge of the internal column data and so they can't know if any of
the values of the rows have been updated. Only that the row instances
themselves have changed. (I have tested it now, just to be safe,
replacing setRowData() with refresh() with the same results.)
Our use case is not so uncommon that we should be struggling so much
with this intended functionality.
Thanks for your prompt reply.

There is no perceived change in behaviour.
I've tried wrapping the whole FieldUpdater.update() contents inside
the execute() action, but to no avail.
I'm not sitting in front of my GWT development machine,so I don't have

You've updated the backing list, but not refreshed the view (at least in
the sample).

Hello.
I've created a test case of my CellTable issue as a self contained
panel that can easily be imported into any project:
http://pastebin.com/zDLPKUNh
Basically I have two Date class fields in my row model, a startDate
and an endDate. Each Date has two columns in the CellTable (called
batchTable), one to display the actual date (a DatePickerCell) and
the other being a text input cell for the time.
When the FieldUpdater of the startTime or endTime is fired we parse
the value, save the new time and call batchTable.setRowData() with
the updated object and row index.
The problem is that when FieldUpdater is fired, the cells do not
update. I specifically edited the FieldUpdater of the endTime cell
to be an hour later than what it was set at.
I've checked as best as I can that all the gets and sets of the
respective startDate and endDate are in order, but I'm thinking that
there's something about CellTable I'm not getting.
Apologies if I've missed anything.
I'm running: GWT 2.3
I've tested it in the latest Chrome and IE9.
Regards, Julian
Try putting your update actions inside a ScheduleDeferred command.
The issue seems to be the coupling between the FieldUpdater and the
cellTable refresh logic. Running the FieldUpdate.update() action after
the browser's refresh loop seems to address this issue.

Re: Extend GWT-RPC protocol to support AMF3 protocol
Like Don said the Flex module in the gwt4air project is not ment for existing Flex projects written in Action Script. It s for new Flex projects and for Java Developers willing to use Flex as the UI technology of their projects. By leveraging GWT there is no need to use stuff like BlaseDS, GraniteDS etc... because one can directly use the powerfull GWT backend APIs (RF, RPC, Requestbuildere, etc..) 2011/8/21 Don Rudo carlosalbert...@gmail.com Thanks for the suggestion; I think gwt4air is for the client side; what we need is actually a way to make GWT RPC understand AMF3 requests from already implemented clients, the actual JEE implementation is done at GraniteDS but it would make no sense to have it running for GWT adding all this extra overhead just for the AMF compatibility, the another solution would be to leave JEE and go for AMFPHP. But a good chance would be to extend the GWT protocol in order to have an RPC which understands the AMF3 requests without adding extra complexity to the project itself. Best regards, Carlos.

Re: Controlling Size(screen) on Mobile Device
Well, the whole resolution independent web development is really cumbersome especially with GWT like web-application UI. Static web-sites either stick to the static (i.e. 960 grid system) or fluid/liquid (floating) UI design. With the static design the content size is always the same no matter of the resolution you are viewing the web-page. This is done because there is an optimal text length. If you expand text-content to the complete size of the display it becomes really hard to read with high resolution displays. So static web-pages tend to stick the fixed sized layouts. However there is also a move to liquid/fluid layouts where you resize the layout based on the viewport. Check out this articles for more information: http://coding.smashingmagazine.com/2009/06/02/fixed-vs-fluid-vs-elastic-layout-whats-the-right-one-for-you/ http://www.maxdesign.com.au/articles/liquid/ These two concepts work well in the desktop context where you can expect screen resolutions 1024px. However in the mobile context you have to expect lower screen sizes. So there are two solutions to that: You can either use liquid/fluid design. However this doesn't always work well because the sections in of your web-app will be to small and the user has to zoom in and out constantly. For example on a tablet it might be viable to have a navigation panel on the left side and a content panel on the right (DockLayoutPanel). However on a mobile phone it might be better to just have the navigation panel and on clicking an item the content panel is displayed. The second solution is to use different View implementations based on the UserAgent (device). There was a talk on the last Google IO conference on that and a sample project on how to implement it. http://www.google.com/events/io/2011/sessions/using-gwt-and-eclipse-to-build-great-mobile-web-apps.html http://code.google.com/p/google-web-toolkit/source/browse/#svn%2Ftrunk%2Fsamples%2Fmobilewebapp Developing a GWT web-app which works on all desktop resolutions as well as on mobile devices are real challenger. Actually it is difficult enough to achieve this if you only want to optimize for different desktop resolutions, especially if you use Charts which require explicit sizes. The MVP pattern can help to have different view implementations and still avoid redundant code. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Use Uploaded Image as Panel Background
As soon as your image is uploaded, you can have a link to it. something like http://my.site.com/images/uploaded_img.png Then, you only have to dynamically change the background of your element : myWidget.getElement().getStyle().setBackgroundImage( http://my.site.com/images/uploaded_img.png); The only trick is to upload the image, move it to a folder visible for your website users, and get the valid url associated. To help uploads, you can use gwt-upload project ( http://code.google.com/p/gwtupload/). Really easy to use. 2011/8/22 DarthG garyker...@gmail.com Hello, I have an AbsolutePanel that acts as a graphical workspace. The user should be able to specify a local image to upload and this image will appear as the background on the panel, for them to work on top of. I understand the background can be set using CSS, but how would one do this dynamically after the image is uploaded? Is there a simpler way to do this using an Image widget the same size as the panel and having the panel sit on top of this widget and set as transparent?

Re: Insane RPC Serialization Error.
Some days ago I had a similar problem. Development version worked fine, but the compiled version gave those errors. What I did to resolve them, was to build my project from scratch. At the end I had a compiled and working version, having the same codebase like before. In the progress of resolving the error I also changed some eclipse settings: - Google Plugin for Eclipse - Default GWT Version from 2.2 to 2.3 - Updated Maven Dependencies: GWT 2.2. to 2.3.0, GWT Maven Plugin 2.2 to 2.3.0-1 Finally I cannot say where this behaviour results from, but this is how I solved the problem.

Re: Insane RPC Serialization Error.
Well, actually It's a massive class definition.
There are 2 piece of that class that I suspect gives troubles...
1) a string with a json definition inside
2) This typed map: MapKeyItem, LookupRow where KeyItem and LookupRow are
other 2 objects with hashcode and equality methods defined properly...
I guess that there are some issues about the map due to the fact that firebug
report to me this stuff...
level = SEVERE { impl=SEVERE, castableTypeMap$={...}, $H=374}
msg = null
thrown = java.lang.ClassCastException { stackTrace=[72], $H=240,
castableTypeMap$={...}

I make a rpc call from GWT client to a server passing an object.
This pojo contain several data ... and a String with some JSON stuff.
The call in DEBUG mode works absolutely fine. Not only in debug mode, but

In production mode... the seralization fails!!! Nothing on server side. I
investigate the call in firebug... and the output is:

Re: Code Does not Compile
Everything to/from the client must be a valid emulated class so one way you can achieve this is to use a Data Transfer Object composed of classes that are valid for the client side. Write a server-side RemoteServlet to receive and translate this DTO into the calls you want to perform and then translate the results into something that you can send back to the client. That's the most straight-forward way I know if doing that you want to do. Others may suggest a different approach but I don't believe it's possible to make these calls directly because of the restrictions imposed by GWT.

Re: Insane RPC Serialization Error.
I had similar issues, all pointed back to some defensive coding. As all calls are aync , behavior will be some what unexpected in few situations. Here are some tricks I played to such errors. 1) try in different browsers. 2) Load the app instance, then try, meaning use once, and second, third, is problem persistent. 2) In your loginConfig file, if is client side code, check for nullability of the object you are casting, sure, what ever object , you are are casting to is null, depending, how implemented the call, async call might be delaying. One trick, test for null and throw Window.alert(blah blah object is null at line and class - till you resolve these issues. 3) I had the habit of coding this.variable=param - this thew null pointer exception in IE9, I removed all this.variable and named params with non-conflicting name. Obviously javascript is not as robust as java, so we have code very defensively. 4) I found, rather I coded more procedural way than forcing all OO concepts in to code, this gave small footprint and performance. GWT likes procedure code. 5) Client side, I did not spend much time but Window.alert is working great for me. These are the things I should not see, if shows, code broke some where, even I kept these in app engine uploaded, of- course I don't have 1000's of users right now. These are my experiences, You can experiment and find what works in your situation. -venu http:schoolk12.appspot.com On Aug 22, 6:48 am, Jambi michael.lukaszc...@googlemail.com wrote: Could you post the class contents?

How to show a User view in GWT app by typing in browser address bar
I have this gwt app which say, runs on http://mygwtapp.com/ (which is actually: http://mygwtapp.com/index.html) The application host a database of users, queried by searching usernames using the search view and results are shown in the user results view. Pretty useful enough. However I need to bb add a way that user view can be viewed by just typing http://myapp.com/user123 I am thinking that the question I have here, the answer is a server side solution. However if there's a client side solution, please let me know. One fellow here in StackOVerflow suggested that the format would be like this: mygwtapp.com/index.html#user123 however the format is important to be like: http://myapp.com/user123 I have tried using GWT Fragment Identifier approach well and works well when the app is in debug mode and when deployed in Tomcat it works when the main page has loaded already. This approach though it works the page is not bookmark-able, i.e. when users type http://myapp.com/index.html#user123 in the browser I get a blank page. Is there any way to achieve this kind of feature? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Aw: How to show a User view in GWT app by typing in browser address bar
You have to use redirect rules on your web server, e.g. nginx, apache, tomcat, etc. That way you can deliver your app's index.html for different URLs based on regular expressions. Once your server delivers your index.html you can do Window.Location.getPath() in your EntryPoint and then do whatever you have to do. The only downside is, that if your user names doesn't follow a specific pattern then you have to redirect nearly every request to your index.html (you would exclude your GWT-RPC/RequestFactory servlet URLs and in general all URLs that point to a file that really exists on your server). So you loose HTTP 404 errors on your web server because you can not decide if the request, that will point to a folder/file that does not exist on your server, e.g. /user123, is wrong and you should do a 404 or if its wrong but you have to redirect to index.html. If you want to keep 404's I think you have to change your desired URL to something like: http://app.com/u/username. That way you could redirect only if you receive a request that starts with /u/. A nice way to make your GWT pages bookmarkable is to use GWT's places framework. GWT Places uses the hash fragment of the URL to store information about the place (what place is active and what application state belongs to that place). -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Editor framework and polymorphic types.
Anyone have any tips on using polymorphic types within the editor framework? I have some paths of my object graph that hold polymorphic types, and their getters return the super type. How can I create the correct editor for these paths? Creating a ValueAwareEditorT where T is the super-type, and I can check what concrete type the object is in the setValue() method, and then... ? Or perhaps another way? Cheers, Aidan. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Try putting your update actions inside a ScheduleDeferred command.
The issue seems to be the coupling between the FieldUpdater and the
cellTable refresh logic. Running the FieldUpdate.update() action after
the browser's refresh loop seems to address this issue.

Re: Funny behaviour in CellTable.
We haven't tried it in compiled mode yet, but it definitely doesn't
work in dev mode for us.
What is your code that returns a value? Neither the
FieldUpdate.update() nor the ScheduledCommand.execute() expects a
value back so I'm a little perplexed as to your context? And what is
MyVariable?
Sorry if I've just lost the plot.

Aw: Re: Aw: How to show a User view in GWT app by typing in browser address bar
Well it would, but your problem is your URL requirement. With standard GWT Places your URL would look like: http://mygwtapp.com/#UserPlace:unique username or db id or if you customize GWT Places you could achieve URLs like http://mygwtapp.com/#/user/unique username or db id. So as you can see GWT places also uses the hash fragment of an URL to store information. So you should only use it if you can change your URL requirement to something that GWT places is able to give you. If you really need this URL requirement then your only chance is to configure your server side rewrite correctly so that your app starts and read the URL path from within your app. Your app then has to decide what to do when it sees the path userXYZ or something other. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

CellTree isLeaf() in practice
I'm trying to display a tree of Categories, following the basic
CellTree gwt examples.
What I am stuck at is determining the leaf condition of a Category.
A Category is-a-leaf when it hasn't children, right? So, here's my
Category (I am using Objectify for appengine persistence):
@Entity
public class Categoria implements Serializable {
private static final long serialVersionUID = 1L;
@Id
Long id;
String nome;
KeyCategoria parent;
public Categoria() { }
public Categoria(String nome) {
super();
this.nome = nome;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public KeyCategoria getParent() {
return parent;
}
public void setParent(KeyCategoria parent) {
this.parent = parent;
}
}
My TreeViewModel is based on AsyncDataProvider (which I pass from
outside):
public class CategorieTreeViewModel implements TreeViewModel {
private AbstractDataProviderCategoria dataProvider;
public CategorieTreeViewModel(AbstractDataProviderCategoria
dataProvider) {
this.dataProvider = dataProvider;
}
@Override
public T NodeInfo? getNodeInfo(T value) {
return new DefaultNodeInfoCategoria(dataProvider, new
CategoriaCell());
}
@Override
public boolean isLeaf(Object value) {
return false;
}
}
So here it is:
dataProvider = new AsyncDataProviderCategoria() {
@Override
protected void onRangeChanged(HasDataCategoria display)
{
updateTree();
}
};
private void updateTree() {
rpcService.getCategorie(new AsyncCallbackCategoria[]() {
@Override
public void onSuccess(Categoria[] result) {
dataProvider.updateRowCount(result.length, true);
dataProvider.updateRowData(0, Arrays.asList(result));
}
@Override
public void onFailure(Throwable caught) {
Window.alert(caught.toString());
}
});
}
The question is: since I don't have a leaf property on my Category
bean, how can I know if it has children or not? By doing a query
obviously, but the isLeaf method needs to return synchronously, how
can I make my rpc call?
Or I can retrieve that leaf information in the getCategorie() call,
filling the property at runtime, but this could be a performance
problem.
What can I do?

Re: Funny behaviour in CellTable.

We haven't tried it in compiled mode yet, but it definitely doesn't
work in dev mode for us.
Alright - at least that's better than what was happening on my side. The
problem was that in dev mode, the NPE exception was correctly caught in
the try/catch block.
In compiled mode, the NPE doesn't exist, it's caught as a
JavaScriptException.
My code example was intended to demonstrate that when MyVariable is
null, then the catch of the NPE doesn't happen in compiled mode.
I was hoping that you were seeing the same thing: the refresh() succeeds
in dev mode, but not in compiled mode because the NPE can't be caught in
compiled mode. The refresh() never got called because of the NPE.
In your case, it's not working in dev mode. In that case, what do you
see when the presenter does not refresh?
Also, is the celltable setup to allow focus to one cell? If so, does the
refresh occur if you set focus to a cell, the blur out of that cell? One
thing I was going to try before I figured out the NPE, was to subclass
CellTable, and start hooking into some of the protected() routines.
What is your code that returns a value? Neither the
FieldUpdate.update() nor the ScheduledCommand.execute() expects a
value back so I'm a little perplexed as to your context? And what is
MyVariable?
Sorry if I've just lost the plot.

Hi Julian,
I was too glib in my earlier reply.
I, too, am seeing this problem. I hadn't completetly tested this app
in production mode, and it fails miserably when compiled.
So, I will post updates to this thread when I get a solution that
works not only in development mode, but also when compiled.
The answer (at least in my case), was the following:
try {
switch (MyVariable) {
case 1: return 1;
case 2: return 2;
.
.
.
} catch (NullPointerException e) {
return 1;
}
In compiled mode, the try/catch doesn't, so the Javascript was failing
at the switch expression evaluation. So, the side-effect was that the
display was never refresh()-ing
Try compiling in PRETTY mode and checking for exceptions.

We have refreshed the view because instead of calling
ListDataProvider.refresh() which simply calls updateRowData() for all
the registered displays, we've done the following:
By calling batchTable.setRowData() we are simply more directly
targeting both the display and only the row that has changed. (Rather
than all visible rows by calling refresh().)
As far as I can tell from the system, the DataProviders have no
knowledge of the internal column data and so they can't know if any of
the values of the rows have been updated. Only that the row instances
themselves have changed. (I have tested it now, just to be safe,
replacing setRowData() with refresh() with the same results.)
Our use case is not so uncommon that we should be struggling so much
with this intended functionality.
Thanks for your prompt reply.

However, after wrapping the setRowData() in a ScheduleDeferred like
so:
Scheduler.get().scheduleDeferred(new ScheduledCommand() {
@Override
public void execute() {
batchTable.setRowData(index,
Collections.singletonList(object));

There is no perceived change in behaviour.
I've tried wrapping the whole FieldUpdater.update() contents inside
the execute() action, but to no avail.
I'm not sitting in front of my GWT development machine,so I don't have
this exactly right,but where are you calling the list.refresh() method?
You've updated the backing list, but not refreshed the view (at least in
the sample).

Hello.
I've created a test case of my CellTable issue as a self contained

Basically I have two Date class fields in my row model, a startDate

batchTable), one to display the actual date (a DatePickerCell) and
the other being a text input cell for the time.
When the FieldUpdater of the startTime or endTime is fired we parse
the value, save the new time and call batchTable.setRowData() with

GWT Date 'week of year' and 'day of week' problem
Hi! Due to the fact that the Java Calendar Class is (unfortunately) not compatible with GWT I’m having some problems: I need to generate a Date-Object out of the Information by “week of year” and “day of week”. With the Calendar-class my code looks like: Calendar cal = Calendar.getInstance(); cal.set(Calendar.WEEK_OF_YEAR, getComboBox_6().getSelectedIndex()+1 ); cal.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY); Is there any possibility to solve this problem by using the normal ‘Date’-class or ‘DateTimeFormat’ or any other suggestions?

GWTCanvas alternatives
I'm trying to create a chart using GWT. The chart has a grid and x and y axis labels and at least one line indicating status over time. The example code I got from a co-worker uses two classes the com.google.gwt.widgetideas.graphics.client package: GWTCanvas and Color. The documentation about GWTCanvas says to use Canvas instead, but Canvas has a very limited number of methods. How do I replicate these methods? - clear() - setFillStyle(Color color) - fillRect(double startX, double startY, double width, double height) - setLineWidth(double width) - setStrokeStyle(Color color) - beginPath() - moveTo(double x, double y) - lineTo(double x, double y) - stoke() Any help is appreciated.

Re: Insane RPC Serialization Error.
Try to reproduce the error with a small example. I would also recommend that. Are the classes KeyItem and LookupRow serializable? Do they implement an interface for serialization? Because they need to. check out this documentation: http://code.google.com/intl/de-DE/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideSerializableTypes -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

AutoBean with JSONP
Hi! I'm trying to use AutoBean framework to transfer data from server
to GWT App. GWT-RPC is not good for me, because i need to cache
responces.
So I'm trying to use JsonpRequestBuilder to fetch data and AutoBean
framework for encoding/decoding.
The simple (and not working) aproach is like this:
servlet's doGet() method ---
String json = AutoBeanCodex.encode(data).getPayload();
String callback = request.getParameter(callback);
PrintWriter out = response.getWriter();
try {
out.write(callback);
out.write(();
out.write(json);
out.write(););
} finally {
out.close();
}
--- client ---
JsonpRequestBuilder jrb; // = ...
jrb.requestString(url, new AsyncCallbackString(){
public void onSuccess(String result) {
AutoBeanDataType bean = AutoBeanCodex.decode(factory,
DataType.class, result);
DataType data = bean.as();
//
}
public void onFailure(Throwable caught) {
}
});
-
Unfortunately, this does not work, because returned data is not
actualy a String, it's a JavaScript object.
I've tried to escape json on the server to make it String:
---
out.write(callback);
out.write((\);
out.write(escape(json));
out.write(\););
---
This works, but in my case it increases responce size from 700kb to
3Mb which is really not good.
Any ideas what to with this?

Re: GWTCanvas alternatives
Generally you grab a Context2d object from the canvas, and most of the methods you identified are exposed there.

Re: AutoBean with JSONP
I've found a solution: it's possible to convert Object to String on
the client:
---
JsonpRequestBuilder jrb; // = ...
jrb.requestObject(url, new AsyncCallbackJavaScriptObject(){
public void onSuccess(String result) {
JSONObject jsObj = new JSONObject(result);
AutoBeandatatype bean = AutoBeanCodex.decode(factory,
DataType.class, jsObj.toString());
DataType data = bean.as();
//
}
public void onFailure(Throwable caught) {
}
});
-
But I don't know about performance: parsing this object 2 times on the
client may be slow.
May be there are some better solutions?

CellTree: is anybody working on fixing it?
Hello! In its current form, CellTree is unusable for anything but simplest use cases. For example, removing a selected node from its parent's ListDataProvider breaks the tree in the debug mode (the tree becomes unresponsive to the user); basically, almost any programmatic operation on a populated CellTree (via ListDataProviders) breaks it visually in some way. Is there an effort under way to fix this widget, or should we use the old widget, or something from a third-party?

Re: CellTree: is anybody working on fixing it?
I haven't tried CellTree myself, so I don't have an opinion on it one way or the other, but if it was me, I'd start by reviewing the list of open bug reports against it and starring the ones that seem to be affecting my app. http://code.google.com/p/google-web-toolkit/issues/list?q=CellTree http://code.google.com/p/google-web-toolkit/issues/list?q=Cell On Aug 22, 6:42 pm, ussuri michael.glas...@gmail.com wrote: Hello!

(perplexing + frustrating) CSS image not found
Hi, I have a compiled project deployed on AppEngine. Some .gif files are not found by GWT. I am perplexed. The CSS file is found. Other .gif images used by the CSS file are found. Looking at DevTools in Chrome, I see which ones are not found. Clicking on the link, the server finds them and shows them in my browser. Why can I directly access them using the url that it is being reported GWT can not find them at. I mean: /images/panel/top.gif --- is found /images/panel/bottom.gif -- is not found by gwt but can be accessed by using the link DevTools says GWT says it's not at. Dev mode shows the same things. It's just beyond crazy. If client bundle is the only way to use things, the docs should say that.

public Animal getAnimal() {
return new AnimalDao().get(keyAnimal);
}
public void setAnimal(Animal Animal) {
this.keyAnimal = new AnimalDao().key(Animal);
}
public void setAnimalTransient(Animal Animal) {
this.AnimalTransient = Animal;
}
public Animal getAnimalTransient() {
return AnimalTransient;
}
}
Class Animal :
public class Animal extends DatastoreObject {
private static final long serialVersionUID = 1L;
private String name;
public Animal()
{
// No-arg constructor required by Objectify
}
public void setName(String name) {
this.code = code;
}
public String getName() {
return code;
}
}
EntityProxy :
@ProxyFor(value = Owner.class, locator = ObjectifyLocator.class)
public class OwnerProxy extends EntityProxy {
void setname(String name);
String getname();
public AnimalProxy getAnimalTransient();
}
Interface AnimalProxy :

void setName(String name);
}
Interface OwnerRequest :
@Service(value = OwnerDao.class, locator = DaoServiceLocator.class)
public interface OwnerRequest extends RequestContext {
RequestOwnerProxy saveandReturn(animalProxy animalProxy);
}
Class OwnerDao :
public Owner saveee(Owner p) {
p.setAnimal(new AnimalDao().get(new Long(259))); // name is
Milou
p.setAnimalTransient(p.getAnimal);
this.put(p);
System.out.println(p.getAnimalTransient.getName()); It works
Milou
return p;
}
Appiclation Implementation :
OwnerRequest animalRequest = requestFactory.ownerRequest();
OwnerProxy ownerProxy = ownerRequest.create(OwnerProxy.class);
ownerProxy.setName(Jean de la Fontaine);
ownerRequest.saveandReturn(ownerProxy).fire(new
ReceiverOwnerProxy() {
// The problem is
here*
@Override
public void onSuccess(OwnerProxy response) {
System.out.println(My name is +
response.getValue()); // It
works My name is Jean de la Fontaine
System.out.println(response.getAnimalTransient().getName()); // It
doesn't work Error :
// Caused by: java.lang.NullPointerException: null
}
});
I can't use the methods getAnimalTransient() on client side,
animalTransient looks empty.
Thanks for your help

[gwt-contrib] Changes setters/clearers com.google.gwt.dom.client.Style to return Style instead of void (issue1530803)

No good. This defeats compiler optimizations big time. We don't like void returns either, but we like big fat slow apps even less.

Re: [gwt-contrib] Re: Changes setters/clearers com.google.gwt.dom.client.Style to return Style instead of void (issue1530803)
Just out of curiosity, does this have to defeat the compiler optimisations? Isn't it known at compile time that those setters will always return the same Style instance? In that sense, from the compiler's point of view, isn't the situation with the setter returning the Style the same as the situation with getStyle() returning the Style?

No -- it may be theoretically possible to analyze that all the methods called don't mutate the object, the current compiler doesn't do it. We have talked about producing better code for the builder pattern, but it is surprisingly difficult to get right in all situations. -- John A.
