Re: need more abstract AsyncCallback class
now it is working nearly perfect - only some raw type warnings remain
- how to get rid of them? my signature look now like this:
private class LoadMapsT extends Map implements AsyncCallbackT
i get 2 raw type warnings - one in signature. this one i can eliminate
by adding Map?,? but then target.putAll(result) isn't working
anymore. so how to distribute ? correctly?

customize CellTable css style
Hi,
I tried to customize gwt CellTable with no success. Am I missing something?
Here is what i did:
1) create custom resource interface:
public interface CellTableResource extends Resources {
public CellTable.Resources INSTANCE =
GWT.create(CellTableResource.class);
/**
* The styles used in this widget.
*/
@NotStrict
@Source(com/company/public/com/company/gbb/css/CellTable.css)
CellTable.Style cellTableStyle();
}
2) create css file in
src/main/resources/com/cayetano/public/com/cayetano/gbb/css/CellTable.css
(note: there are no images for gwt-image attribute, but still compiles with
no errors).
.cellTable {
border: none;
}
.firstColumn {
}
@sprite .footer {
gwt-image: 'cellTableFooterBackground';
background-color: #fffbd6;
border: none;
text-align: center;
color: black;
font-size: 11px;
font-weight: bold;
font-family: Tahoma;
}
@sprite .header {
gwt-image: 'cellTableHeaderBackground';
background-color: #fffbd6;
border: none;
padding: 0px 10px;
text-align: center;
color: black;
font-size: 11px;
font-weight: bold;
font-family: Tahoma;
}
.cell {
background-color: #fffbd6;
padding: 4px 10px;
border: none;
text-align: center;
color: black;
font-size: 11px;
font-weight: bold;
font-family: Tahoma;
}
.firstColumnFooter {
border-left: 0px;
}
.firstColumnHeader {
border-left: 0px;
}
.evenRow {
background-color: #fffbd6;
}
.oddRow {
background-color: black;
}
.hoveredRow {
background-color: #fffbd6;
}
@sprite .selectedRow {
gwt-image: 'cellTableSelectedBackground';
background-color: #fffbd6;
border: none;
text-align: center;
color: black;
font-size: 11px;
font-weight: bold;
font-family: Tahoma;
}
.cellTableLastColumnHeader{}
.cellTableHeader{}
.cellTableLoading{}
.cellTableSortedHeaderDescending{}
.cellTableFirstColumn{}
.cellTableFirstColumnHeader{}
.cellTableFooter{}
.cellTableKeyboardSelectedRowCell{}
.cellTableWidget{}
.cellTableSelectedRow{}
.cellTableLastColumn{}
.cellTableLastColumnFooter{}
.cellTableSortableHeader{}
.cellTableKeyboardSelectedRow{}
.cellTableKeyboardSelectedCell{}
.cellTableHoveredRowCell{}
.cellTableCell{}
.cellTableEvenRowCell{}
.cellTableFirstColumnFooter{}
.cellTableOddRow{}
.cellTableEvenRow{}
.cellTableSelectedRowCell{}
.cellTableSortedHeaderAscending{}
.cellTableOddRowCell{}
.cellTableHoveredRow{}
3) create cell table with overridden resources
CellTableTick historyTable = new CellTableUpDownBetView.Tick(5,
CellTableResource.INSTANCE);
Result: Default css style is not shown, in fact no style is shown.
Could you help please?
Regards.

Re: Is there a way to generate i18n property from Constants?
When you compile your project, pass the -extra argument with a folder path (e.g. -extra extras), GWT will generate the *.properties there.

Re: onKeyDown getting incorrect keyCode
key code != char code. Different keys have different (key) codes, even if they produce the same chars. You should only have to handle the KeyPress event (so, use a KeyPressHandler instead of the deprecated KeyboardListener). Note that you'd have to take special care to a few chars too: '0' (because Firefox fires KeyPress events even for keys that don't produce chars, such as the shift key) and '\t' (otherwise you'll prevent tabbing out of the field) at least, maybe '\n' too. I believe it's best to just sanitize the value on the ChangeEvent of the field (because the user could paste anything it wants into the field, for example), but YMMV (the rest of our team, and our client, disagree with me, so we're using a KeyPressHandler to filter keys upfront; but you still need to sanitize the value somewhere –ChangeEvent or getValue– to handle the paste use case) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: SuggestBox in Editor
It's hard to use a SuggestBox for anything else than a String value (believe me, we're struggling with it for weeks, regularly stumbling on a new edge case –well, we're asking our server for suggestions, and we need to dispatch ValueChangeEvents, so maybe it's a special use case–). If you can synchronously convert the String value into the type of value you need (and you don't need accurate value change events), then it should be quite easy: wrap the SuggestBox in a Composite, similarly to how ValueListBox wraps a ListBox. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Login security question
Hi According to article LoginSecurityFAQ, http://code.google.com/p/google-web-toolkit-incubator/wiki/LoginSecurityFAQ , I have a point that I really want someone to make it clear for me. From the article, Your server will then validate this login, and return a sessionID to your GWT app. The GWT app will store this sessionID in a static field. For every further request your GWT app makes to your server, include this sessionID in the payload of the request. (Either in the JSON data or the object you are transferring using GWT-RPC). I assume the server returns the sessionId by RPC to the client after validation. How can I include this sessionID in the payload of the request using GWT-RPC? How can I tell the sessionID is in the payload of the request or not in the payload? Thanks Ming -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: need more abstract AsyncCallback class
i got it - it is similar with collections:
private static class LoadMapsK,V implements AsyncCallbackMapK,V
{
private MapK,V target;
protected LoadMaps(TaskDoneEvent ev, MapK,V whereTo) {
target = whereTo;
}
@Override
public void onFailure(Throwable caught) {
Window.alert(caught.getMessage());
}
@Override
public void onSuccess(MapK,V result) {
target.putAll(result);
}
}
thx to both of you!

i am fairly new to gwt and struggling some how on correct/nice RPC
implementation (it is working but code becomes ugly). On my first GWT

to be used in combo boxes for instance).
so if i have a widget that needs 3 different lists (probably
ListString or MapString, String) i specify a service-method for
each list. the problem is to load all those lists, i have to implement
one class (...implements AsyncCallback) for each list.
but the only difference between this implementations is that they load
the result in different lists:
public void onSuccess(){
list1 = result
}
so how to implement an abstract callback class that could load its
result into a given list/object (- a field of mother class)
(if call by reference would exist in java i would giv list1 as an
parameter for constructor and onSucces would load the result into this
reference?!)
an optimal implementation would be if the result type could be a
generic type: A class lie this:
class GeneralCallbackT implements AsyncCallbackT{
public GeneralCallback(T target){
...
}
public onSuccess(T result){
target = result;
}
}
is it possible to get such an abstract callback class?

Yes, the declaration of your UiBinder interface is important for understanding the problem.

Re: suggestionBox backed with pairs value-text (id-ambiguous name)
Each suggestion can give a display text (what will be displayed in the suggestion list, would be the name+id probably in your case) and a replacement text (what will be used as the value, and displayed in the text box upon selection in the list of suggestions). For this, you have to provide your own SuggestOracle. If you don't want to implement your own matching logic, then you can delegate to a MultiwordSuggestOracle, where you'll put the display text, and then convert the returned suggestions to your owns, by matching the display text back to the replacement text (and yes, this means having no duplicate display text, but that's a given if you want your user to pick the right suggestion). In other words: - build a MapString,Suggestion from the display text to the suggestion (with the same display text, and the ID as the replacement text) - put all the keys from this map in a MultiwordSuggestOracle - delegate the call to your oracle to the MultiwordSuggestOracle, wrapping the callback to transform the result back to your suggestions; by looking up the text into the map you previously built and building a new response with the result. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT custom tree with styling.
Hi all Struggling a bit with styling a gwt tree to fit a design I got handed by some people who actually know this stuff. Posted a question on Stackoverflow: http://stackoverflow.com/questions/5623097/gwt-tree-styling For instance, how do I get the leaf images on the right side instead of the left side. And how do I make the leafs react to mouseover. It seems when you look at the HTML code generated by the GWT there's a lot of table elements and divs that you can access and style. Do I have to make my own renderer to get complete control of the tree layout If I get this working I will write a small tutorial about it since lots of people seem to struggle with styling and GWT. /x -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Cell List: add non-data rows
I need to add the following functionallity to a Cell List: - Grouping. Add a header for each group of rows. - Drop indicator. Add a placeholder to indicate that the drop is valid. My initial thought was to create a custom CellList and add extra rows (divs) for the group headers and drop placeholders as needed. The problem is that AbstractHasData works on a 1 to 1 relation between data items and rows. Adding extra divs for headers or placeholders messes-up the HasDataPresenter. I would like to know if someone has tryed to do something similar or has any recommendation on how I can achieve this.

Second part: Sending the session id via RCP must be done via a separate String in your RPC interface. So manually add a String to your RPC. Validating: Your server can then compare those two values.

Re: Login security question
Hi Leung, if you're realizing the log in and log out functionality within your GWT app and not with other mechanism (e.g. container based authentication), you just need to make sure that the log-in RPC call to the server returns an unique sessionID to your client. For the generation of the sessionID on the server you can use the UUID class and then just send uuid.toString() to the client. This token/sessionId needs to be send to the server with each RPC call to ensure the server-side check if the session is valid, so you also need to store it in your client app, as long as the user is signed in. On the server side you just need to keep track of all currently valid sessionId's.

TextBox - Prevent delete/backspace
GWT'ers, I have a textbox that I do not want to prevent the user from typing into entirely, but I do want to prevent the user from removing characters; i.e., I want the existing format to remain the same, and the user only be allowed to update each character in the textbox value individually.

Re: CellTable with only div's?
That is true. We are avoiding Vertical/HorizontalPanel. In fact, our idea behind using CellList is for the ability of use float:left (overriding CellList.Style) in even and odd cell styles. We couldn't to this with elements in CellTable because they are TDs (float:left and td are not very good friends) By the way, CellList with cells in float:left is an excellent way to create an Image Gallery for hundreds of images. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How does my servlet cleanly throw an exception
I'm trying to throw an exception from my servlet back to the client without breaking anything along the way, and having no success. First I was throwing an InvocationException, but this created an error it was an unrecognized exception. So I threw a ServletException. This is acceptable on the Servlet side, because doPost is specified to throw ServletException. But on the Client side it creates a problem, because ServletException is not IsSerializable. And I can't create a Shared Exception that IsSerializable and inherits from ServletException, because ServletException is not defined on the Client side. So, how DOES my RPC code pass an exception back to the client without generating any errors for the servlet code?

two questions about SuggestBox and formPanel
Hi Dear Google Web Toolkit members, I'm new in http://groups.google.com. And I have two questions please help me with that questions. Question number one: I'm using suggestion box for search. And I have an ValueChangeHandler on that SuggestBox. And I'm making an RPC call on each value have change and want to get from database several entities which current property value has substring of the word i typed. For example if I have an entity (companies) and my entity has a property called (name) and when I type app and also I've got Entity which property(name) value is Apple I want my query to return that entity. But as I can't send such query for example in RDB (Mysql) I was sending such query SELECT * FROM companies WHERE name LIKE '%app%'; So please suggest how can I make that google like suggestionBox And the second question: Why do we need using form instead of simple datasending to server using RPC I'm creating registration form and think.. what is the difference of sending data to the server using FormPanel or using RPC call. I noticed that for form I don't need to organize RPC and create two more classes But I think maybe there is more reason of using Form instead RPC Calls please tell me what other reason could be of using form. Мaybe it's because that with form we also can send some files ? Using FileUpload?

GWT Eclipse Plugin and Unit Tests
Hi, I'm following the MVP pattern and I'm writing many unit tests for the presenters. In order to also test the methods that are protected or have only package visibility I'm placing the unit tests in the same package as the presenters, however they are located in a different folder. I.e. I have the following folders: src/main/java/com/playground/client src/test/java/com/playground/client I'm using EasyMock 2.5 for my tests and Eclipse complains about the usage of the Capture class: org.easymock.Capture can not be found in source packages. Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly. Even if I explicitly remove the test classes from my GWT module ( source path='client' excludes=**/*Test.java/ ) Eclipse does not care about it. GWT compile works fine and I can start the application in the development mode, however, I do not get rid of the red error markers in Eclipse. Is there any possibility to tell the GWT Eclipse plugin (GWT version 2.1.1) that it shall ignore the src/test/java path?

Re: MVP vs PureMVC
We've been using PureMVC at organization for many years, and when I created our first GWT project, I decided to keep things consistent. So far, it's been smooth sailing, however I haven't done any memory profiling. Overall though if you've used PureMVC before, then you'll be able to dive right in and start building your project. GWT projects being no different than any of the other platforms PureMVC has been ported for.

GWT and CSS3 Gradient
Hi! I'm quite new to GWT (I'm a PHP developer assigned to do the front-
end of a Java application because of my CSS knowledge) and what I'm
trying to do is use CSS3 Gradient using a stylesheet imported via
ui:style src=main.css
On main.css I have
.custom-buttom {
background: -moz-linear-gradient(top, white, #72C6E4 4%, #0C5FA5);
background:-webkit-gradient(linear, left top, left bottom,
from(white), to(#0C5FA5), color-stop(0.03, #72C6E4));
}
But when I try to view via the Google Chrome plugin, it collapses the
whitespace within the parenthesis leaving me with
.custom-buttom {
background: -moz-linear-gradient(top, white, #72C6E44%, #0C5FA5);
background:-webkit-gradient(linear, lefttop, leftbottom, from(white),
to(#0C5FA5), color-stop(0.03, #72C6E4));
}
which breaks it, hence preventing the rendering of the gradient.
Is there another way to do this or maybe a way to prevent the
whitespace from collapsing.
Thanks.

GWT front end + Drools Expert in the business layer - anybody using it?
Hello, I have a problem that I need help on. I have a simple drools application that exposes a business method that takes in parameters and returns a value after invoking a some rules expressed as .drl files.

It appeared as if the rules hadn't fired at all. I have had no errors with respect to finding the relevant classes/rule files as I have made sure that the correct files (Drools binaries, .drl files) are available at the runtime classpath while testing this in the hosted mode.

How to use a ValueListBox with RequestFactory Editor?
I can't seem to find a single example of how to integrate a ListBox or
ValueListBox with an Editor.
I've put an VLB in my editor, and it sets the value, but if I add any values
to the VLB, it just tacks them onto the end (So I'll have two of the same
items in the list, one added by the editor, and the other added by me when I
add the VLB's acceptableValues.)
A UI has a list of MyProxy (which is a Thing), when a user clicks on a
thing, the editor is shown (via the workflow). The
item is retrieved and shown in the editor. The editor needs to load the
list of MySubProxy (SubThings) and set the selected item as provided by the
MyProxy (Thing) object.
Instead, the edit correctly sets all teh values, but appends the acceptable
values (ListMySubProxy) to the list which already contains the value set
by the MyProxy object.
Does anyone have an example of this working that they can share, or can you
point out what I'm doing wrong (code below)?
eg: (obviously, I've changes the names of the things to protect my
organization's model.. and added ... where code exists but is not needed
for the example)

Re: Editor doesn't display chained Entity
did you call request.with(*paths*)? Where *paths *is a list of strings

Re: MyEclipse GWT code gen
If you have a large DB (like we do) with lots of tables foreign key relationships, it will generate a BUCKET LOAD of code. You'll probably spend more time removing unneeded code then you would if you started from scratch. Plus it adds in jars to your pom/project that are used by MyEclipse, etc. (at least it did for me). You also get forced into doing things the MyEclipse way, which may not be compatible with your dev groups code style as it generates all the code, etc for you. It will generate queries/hql/sql for every conceivable field. (eg: getMyClassByFieldA, getMyClassByFieldB, etc...) I found it good to get an idea of how Editors Request Factory works since the docs from Google are so sparse. If you have a relatively small DB and tables with few relationships, it is probably a good way to jump-start.

Edit multiple properties of an object
Hello,
I want to edit multiple properties of my object in a second class (it is
messy otherwise).
I saw the following in the documentation:
class HasBagOfStateEditor implements EditorHasBagOfState {
@Editor.Path(state)
BagOfStateBiographicalEditor bio;
@Editor.Path(state)
BagOfStateUserPreferencesEditor prefs;
}
But it looks like it is editing multiple properties of a the sub element
state of the object, not on multiple properties of the object itself.
How can I edit multiple properties of the top object being edited ?
That would be something like that:
@Editor.Path(this)

What's the context of the code sample? For example, are you already in an

Getting Request Factory to work on the GWT-Eclipse environment
Hello! I'm trying to make Request Factory work on GWT plug-in (2.2.1) for Eclipse 3.6 and I've run into a dilemma. While I got most of the coding required done, not an easy task given that I had to go through a lot of references and head scratching, my real troubles began when I put persistence code which is supposed to be server-side only on my service/locator classes. I use the same persistence code framework that I normally use for RPC style services. Obviously, GWT would refuse to compile when code like that is present in the client or shared package. However, if I move the offending class to the server package, the GWT editor reports an impending build error because the class referenced by the @Service annotation in other classes is no longer included in the client/shared package. How can I resolve this? I've tried other sample code before but I have no idea how the others got them to work without getting past this. - Owen -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Which method of HandlerManager is ClickListenerCollection.fireClick(widget w) similar with ?
In gwt 1.5, I used ClickListenerCollection to manage listeners. But in
gwt 1.6 It has been deprecated, so I used HandlerManager.
public void onBrowserEvent(Event event) {
switch (DOM.eventGetType(event)) {
case Event.ONCLICK:
if(clickListeners != null){
clickListeners.fireClick(this);
}
break;
}
}
ClickListenerCollection = use method: fireClick(Widget w)
HandlerManager = which method is similar with fireClick? fireEvent ?
- And How to use

[gwt-contrib] Re: Trying to address issue 6234 (Support RequestFactory service inheritance on the client) (issue1411802)
Thanks for taking a look at this. - Let me address your second point first as it is much easier for me to talk to it (I hope I understood it correctly): You are correct. The generator needs to be changed. I forgot that in my little test app, I overwrote the RequestFactoryGenerator to acommodate for this. But it should be only a minor change to make the 'protocol' send the name of the inheriting interface (if there is one) instead of the declaring class. The change should be in RequestMethod, line 78. I am going to add a new patch with that change (again untested, had no time today to get a local GWT environment set up). - Your first point is much harder to address, since I am not sure what 'these' refers to in your sentence? The generic super request contexts or the inheriting request context? Why do they need an annotation and why should they not extend RequestContext? - Overall, I think I understand your hesitation to get this fixed in this naive way, since you indeed have a use case where this current behavior is beneficial. In my opinion (as someone who is just learning GWT) the current behavior is a little bit weird and not very intuitive. It also doesn't allow for generic Request Contexts which would be very useful for code reduction and avoidance of copy and paste. I was mostly just hoping that an easy fix could still make the 2.3 release. Thanks again.

[gwt-contrib] Improving TouchScroller to allow native document level scrolling when appropriate. If the scroll... (issue1410803)
Reviewers: pdr, Description: Improving TouchScroller to allow native document level scrolling when appropriate. If the scrollable widget is scrolled as far as it can go in a direction, and the user tries to scroll in that direction, then we defer to document level scrolling. For example, in the Showcase app (which is not a mobile specific app), if you scroll the menu bar to the bottom, then scrolling it again allows the document to scroll down, revealing the rest of the page. It isn't perfect because we cannot disable native scrolling in one direction (as in, allow native horizontal but disable native vertical), but its a drastic improvement and make Showcase usable on mobile. This change also fixes a bug in TouchScroller where it always busts the next click, even if Momentum has finished. The next click should only be busted if the user interupts momentum to stop it. Also, we cancel momentum on WindowResize (and by extension, orientation change) to account for the fact that resizing the scrollable widget will cause the contents to reflow, and the old scroll positions become stale.

[gwt-contrib] Re: Comment on CodeSplitting in google-web-toolkit
Comment by mohanam...@gmail.com: I believe GWT Team deserves a lot of credit for their contributions to the AJAX toolset. When we standardized on GWT, my vision/hope was that GWT would emerge as the #1 (top) toolset for AJAX development. Are we there yet? We designed our own frameworks on top of GWT for modular development and dynamic registration at onModuleLoad. But the initial download and the login screen takes about 40 seconds depending on the network bandwidth. Unless we supply some toys to play with, this is not acceptable performance. We have been looking for ways to optimize the initialization. The code spliting feature did sound promising, iniitally. I went through its documentation and examples for several times. I could be missing something here. But something does not look right. The GWT code splitting feature does not easily work our modular design. Too invasive - requiring insertion of GWT.runAsync calls in the code. (Hacking?) In my experience, well-designed features are highly intutive and extremely flexible. Unfortunately, the GWT Code Splitting is not even close. For example, can I simply designate an EntryPoint in module.gwt.xml to be loaded on demand? A simple onDemand=true/false in the entry-point tag could have been very elegant solution. Some people believe in simplicity. Any thoughts please?

[gwt-contrib] Re: GWT Private/Protected Members
I understand the cautiousness regarding what is public, but I also
believe that protected methods already have the protection necessary,
assuming that developers who are extending a class usually knows what
they are doing, and the source code is available so developers can
check, and maintain compatibility.
Even methods that are strict for infrastructure could have a suffix
( or prefix ) that indicates developer to use it with caution, and
that this method is not guaranteed to exist in future releases:
E.g:
//The current implementation for the private setNewSelection() method,
could be as follows
public class SuggestBox ... {
protected void setNewSelectionImpl(Suggestion curSuggestion) {
//code
}
}
This way gives developers a great flexibility to extend GWT classes,
and even introduce temporary bug fixes.
In a future release, GWt decides to expose this method as a concrete
implementation and could change to:
public class SuggestBox ... {
protected void setNewSelection(Suggestion curSuggestion) {
setNewSelectionImpl(curSuggestion); // this will maintain
compatibility, but is not required at all.
}
}
However, the method setNewSelectionImpl can completely disappear as it
is an draft and not part of the final API, therefore developers will

Anyways, just bouncing ideas. I also understand that if the standard
is overused, and never brought back to the GWT team so it can make
part of the API, it could create chaos among GWT developers.

Log: Cherry pick r9912 and r9914 to releases/2.3 (add
CSS_ATTRIBUTE_START to HtmlTemplateParser, and fix things it
broke). Someone didn't run the smoke tests on the relase
branch, ahem.

Re: [gwt-contrib] Re: GWT Private/Protected Members
We've tried to get better about that kind of thing over the years. The
widgets you listed are among our oldest.
The new widget family described at
http://code.google.com/p/google-web-toolkit/wiki/CellBackedWIdgets should be
better on this score. Re: Tree in particular, you might consider trying
CellTree instead.
When you bump into a particular spot that is thwarting you and see a way to
open it up without breaking existing apps, we're always eager to receive
patches: http://code.google.com/webtoolkit/makinggwtbetter.html

I understand the cautiousness regarding what is public, but I also
believe that protected methods already have the protection necessary,
assuming that developers who are extending a class usually knows what
they are doing, and the source code is available so developers can
check, and maintain compatibility.
Even methods that are strict for infrastructure could have a suffix
( or prefix ) that indicates developer to use it with caution, and
that this method is not guaranteed to exist in future releases:
E.g:
//The current implementation for the private setNewSelection() method,
could be as follows
public class SuggestBox ... {
protected void setNewSelectionImpl(Suggestion curSuggestion) {
//code
}
}
This way gives developers a great flexibility to extend GWT classes,
and even introduce temporary bug fixes.
In a future release, GWt decides to expose this method as a concrete
implementation and could change to:
public class SuggestBox ... {
protected void setNewSelection(Suggestion curSuggestion) {
setNewSelectionImpl(curSuggestion); // this will maintain
compatibility, but is not required at all.
}
}
However, the method setNewSelectionImpl can completely disappear as it
is an draft and not part of the final API, therefore developers will
be using it with caution.
Anyways, just bouncing ideas. I also understand that if the standard
is overused, and never brought back to the GWT team so it can make
part of the API, it could create chaos among GWT developers.
Cheers!
