Security while deserializing/constructing object on server side for a POST request
Hi There,
While i was looking at a POST request on a sample application i observed
that the POST request is carrying the following piece of text in the body
java.lang.String/2004016611|N
Here, my question is, is GWT deserialization process is using this
representation to construct a String object like below?
java.lang.String("N")
If so are there any preventive measures implemented to
avoid instantiating arbitrary object being constructed to avoid any attacks
by a hacker? Now imagine the attacker
constructing a FileOutputStream("/etc/passwd") - depending on the user
the application server is running, this would create a huge security risk.
Your suggestions are very much appreciated.
Regards,
bala.

Yes. Deserialization is based on a white list (see
SerializationPolicy), computed at the time you compile your GWT app (a
*.gwt.rpc file). You can customize this by overriding
RemoteServiceServlet#doGetSerializationPolicy (which by default reads
the *.gwt.rpc file following a naming convention).
Also note that in latests versions of GWT (starting with 2.0 ? maybe
only 2.1, dunno) you can have type names obfuscated.

Even if he could create it, he would still need a mean of reading its
content and have it returned on the wire.

Even better would be using so that when the text is clicked
the radio button is selected.

I believe the idea is that you use a "request scoped" transaction/JPA-
session (or whatever, I'm not used to JPA/JDO and all that stuff).

Simple question about jars
Hi community members, I am using classes which are part of org.w3c.css.sac. They are located inside the GWT development jar "gwt-user.jar", which means I don't have to add external jars during coding. However if I run my GWT project I am getting the error java.lang.NoClassDefFoundError: org/w3c/css/sac/InputSource If I now download the corresponding sac jar file and put it into war/ WEB-INF/lib, it works. My question is now the following: is this a bug or a feature? Shouldn't the usual development classes also be located inside the lib directory on default.

GWT client-side thread or asynchronous call ?
Is there anything similar to using java threads that I can use in my client side code ? In my application a user types a search term into a Text box. For every character typed in my code goes and searches in a dataset for results containing the search string. These results are then returned and displayed in a List. But the problem is that because my search + display code is so slow, it makes the typing in very sluggish for the user (i.e. they can’t type the next character in until the search + display code has returned). Ideally I’d like to run the search+display code in a separate thread – so that the user can continue to type in the Text box. But I understand that threads are not supported in GWT client-side coding ? Or is it possible to have the search + display in an only client-side asynchronous call ?

Re: GWT client-side thread or asynchronous call ?
Your ajax calls should be asynchronous so your client-side ui shouldn't be slowed down by making the calls to the servlet to handle the lookup. Are you sure you aren't making synchronous calls to the server? Also, use direct dom manipulation over the widget supplied methods; get a widget's dom element via its getElement method.

css background image usage with UiBinder
Hi All.
First of all, i looked through mail archive, but subject
still not clear for me.
So, he is my code:

public interface Resources extends ClientBundle {
public static final Resources INSTANCE = GWT.create(Resources.class);
interface Style extends CssResource {
String myStyle();
}
@Source("res/backgroung.jpg")
ImageResource backgroundImg();
@Source("res/common.css")
Style style();
}
res/common.css:
@url backgroundImg backgroundImg
.myStyle {
background: url(backgroundImg) left top repeat;
}
SomeWidget.ui.xml:
SomeWidget.java:
public class SomeWidget extends Composite {
//...
static {
Resources.INSTANCE.style().ensureInjected();
}
public SomeWidget() {
initWidget(uiBinder.createAndBindUi(this));
}
}
when im launching app there is no background image, any comments ?
Thanks

If you can target just HTML5, then you could use WebWorkers: http://www.whatwg.org/specs/web-workers/current-work/ At the moment, you'll have to hand roll the JSNI to access them, but GWT proper will be supporting HTML5 soon-ish.

Re: GWT client-side thread or asynchronous call ?
Hi, Traditional javascript (to which gwt java gets converted) architecture is basically mono-thread in terms of real concurrent execution: so, gwt has to stay mono-thread also. The only possibility that I see to get muti-thread (in a standard manner) with JS is HTML5 bu to my knowledge GWT doesn't (yet) take advantage of the new html5 workers as described in http://www.ajaxwith.com/JavaScript-Worker-Threads.html I wonder if there is a roadmap to html5 workers for GWT. regards didier On Nov 18, 3:41 pm, MickeyR wrote: > Sorry, I probably was not clear.

Building First Web App with GWT
I was wondering if anyone could offer me help in finding resources for creating my first web application with GWT. I have the basic idea and functionality that I would like the site to start with but thats about it. I am a mid level developer with little experience actually planning a robust application. The basic concept behind my application is that it is a book study club with a corresponding workbook. Users have to read certain text and then answer information based upon the weeks text. Their answers are saved and can be reviewed at any time they can have thier answers emailed to them or printed from the screen. I want to create the functionality that allows users to discuss the weeks topics with other users. I want everyone to be reading the same thing at the same time. Also I want to add in the ability for users to invite others. It will be a 13 week course run 4 times a year and before the beginning of each course I will send out email invites with a required date to get signed up by so everyone can be on the same page. I would like to build this application through 2011 and hopefully launch Jan 1,2012. Basically its an extremely focused course study. Any thoughts on how to get started with this? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: UiBinder fails after upgrading to gwt 2.1.0
I have just spent the last few hours struggling on a similar problem
of
java.lang.AbstractMethodError:
org.apache.xerces.dom.ElementNSImpl.setUserData(Ljava/lang/
String;Ljava/lang/Object;Lorg/w3c/dom/UserDataHandler;)Ljava/lang/
Object;
at
com.google.gwt.uibinder.rebind.W3cDocumentBuilder.startElement(W3cDocumentB
uilder.java:
130)
turns out that it has indeed something to do with xerces. It has
to be version 2.9.1
Hope that helps,

Re: Editor and enumeration or object cast
Hi.
Here is my EnumEditor implementation based on a ListBox. It should
give you an idea of how to implement it using option buttons:
package com.leasingsaas.client.ui.widgets;
import java.util.HashMap;
import com.google.gwt.editor.client.LeafValueEditor;
import com.google.gwt.user.client.ui.ListBox;
public class EnumEditor> extends ListBox implements
LeafValueEditor {
Class clazz;
HashMap index = new HashMap();
public EnumEditor(Class e) {
super();
this.clazz = e;
int idx = 0;
for (T t : e.getEnumConstants()) {
this.addItem(t.toString());
index.put(t, idx);
idx++;
}
}
@Override
public void setValue(T value) {
if (value == null) {
setSelectedIndex(-1);
} else {
setSelectedIndex(index.get(value));
}
}
@Override
public T getValue() {
int idx = getSelectedIndex();
if (idx == -1)
return null;
else {
System.out.println("Returning value of: " +
getItemText(idx));
return Enum.valueOf(clazz, getItemText(idx));
}
}
}

Re: Sample App using DI/Gin, MVP, UiBinder, etc
Ashton, The example is very cool and helpful. Thank you. One thing I am struggling with is the ActivityManager. I am trying to manage a composite through the activity manager. I was hoping that you had figured it out but I see that you also pass a SimplePanel mainActivityManager.setDisplay(shell.getContent()); Do you know what I need to do so that ActivityManager.setDisplay function doesn't force me to pass an "AcceptsOneWidget" object? For the sake of the argument, I want to be able to pass the whole shell, like this: mainActivityManager.setDisplay(shell); Thank you.

newbie to gwt - trying to get publish/subscribe working
Hi,
I've recently just started looking into GWT, and am looking for a way
to make a project/package subscribe to channels that other widgets are
publishing. I just tried to get some simple code to work (pulled
partially from a site somewhere), but have no idea if I'm even on the
right path.
public native void tryJS()/*-{
$wnd.createJS = function () {
console.log("we've reached the tryJS function!");
};
}-*/;
public void onModuleLoad() {
tryJS();
...
To my knowledge, a function called "createJS" is created, which I'm
not even sure how to trigger, though preferebly I'd like to just
implement some javascript that equates to
dojo.subscribe("channelName") or something... Can anyone point me in
the right direction or let me know what I should be doing?
Thanks,
Moiraine

"Illegal argument type for number format" error during gwt compile when trying to use {0,number} or {0,number,integer} in a message bundle properties file
The offending message in Messages.properties looks like this:
widget_recordEditor_info_recordsDeletedConcise = {0,number,integer}
{1} deleted.
And here's the output from the gwt compiler:

I have tried a bunch of other variations too (e.g. {0,number,#,##0})
to no avail. Is there any way to specify a message parameter is an
integer for formatting purposes (and so the generated method takes an
int, rather than String, parameter), or is it just not possible? I'm
using gwt 2.0.4 and the gwt maven plugin to invoke the gwt compiler.
Thanks,
Ian

[ERROR] Invalid version number "2.0" passed to external.gwtOnLoad(), expected "2.1"
We're migrating our GWT 2.0.4 application to GWT 2.1.0. I've therefore upgraded my Google Plugin for Eclipse to GWT 2.1.0. When I try to run our application in the GWT debugger in Eclipse (Debug as web application, go to its URL in Firefox) I get the following message: Connection received from localhost:47526 [ERROR] Invalid version number "2.0" passed to external.gwtOnLoad(), expected "2.1"; your hosted mode bootstrap file may be out of date; if you are using -noserver try recompiling and redeploying your app Recompiling doesn't resolve the problem. Also changing the version from 2.0 to 2.1 in the line var $hostedHtmlVersion="2.1"; in the files hosted.html in the war directory doesn't resolve the problem. I cannot find any explicit instructions to migrate from GWT 2.0 to 2.1. My environment: Ubuntu 10.04 LTS Firefox 3.6.12 with Google Web Toolkit Developer Plugin for Firefox 1.0.7511 Eclipse Helios with Google Plugin for Eclipse with GWT version 2.1.0. Any suggestions how I can resolve this problem? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Java Exception lost in 2.1.0 works in 2.0.4
Hi All,
I have a web app where I exposed a class's static method using JSNI,
as in the JSNI example. I execute the method from the native event
handler.
Within the method, I try and catch, and return any exception's message
as the method's return value.
The method works properly in 2.0.4, but in 2.1.0 it only works in
devmode
In 2.1.0 production mode any exception I get returns "Index:-1, Size:
0" and is always in the Throwable catch. With no Throwable catch, the
browser states "object error".
public static String parse(String script) throws ParseException{
try {
CLBParse parser = new CLBParse(new
MyStringReader(script));
SimpleNode root = parser.Input();
return "";
} catch (ParseException e) {
return e.getMessage();
}catch( Throwable e) {
GWT.log("something bad", e);
return e.getMessage();
}
return "";
}
public native void export() /*-{
$wnd.TryParse =
$entry(@com.test.app.client.CalcScriptReformatter::parse(Ljava/lang/
String;));
}-*/;
I've tried with and without the $entry wrapper.
Is this a bug in 2.1.0, or should I be doing something different?
Thanks,
-Rob

Re: Request order
Hi, > batch them (the requests) from client and push them in same http > request :) Allready done, however, this is a little optimization but no solution. It does not disable a user to click 4 times on the same button. After the first one I don't have any idea whether 3 other clicks will follow or not. When there is no easy feature to support this, than the easiest thing is to number any requests from client and execute them only in order.

Setting aside transaction semantics (commit/rollback) since you're probably not interested in implementing that, undo/redo can be performed by attaching a sequence number per write to the server, keeping that SN in undo/redo stacks on the client, manipulating the stacks as appropriate. replay requires a keystroke logger.

Re: GWT client-side thread or asynchronous call ?
I understand now & sorry for the confusion. It might actually be faster to do an ajax call to do the look-up because it will be asynchronous and have little impact on your ui. If for some reason you can't do that then use SpeedTracer to analyze where you client side code is getting bogged down. It is a great tool and can provide numerous insights as to where you need to focus your attention. Jeff On Thu, Nov 18, 2010 at 9:41 AM, MickeyR wrote: > Sorry, I probably was not clear.

Re: cannot create servlet in Eclipse helios
I don't know if this is related but there has been a problem with the dtd the web.xml file uses. It isn't available and Eclipse marks the file as having errors.

Re: GWT MVP and RequestFactory
Thanks, you got me on the right rack. I didn't realize that more information on the exceptions was available in the dev mode console of eclipse. My domain entity objects had some Boolean accessors which I had named isProperty() instead of getProperty(). I changed all of those, and also made the domain service methods 'static' like you suggested. Now the application is running, but when it fires a request for UserInformation, I get a null pointer exception. After debugging, it gets into AbstractRequestContext.doFire(receiver) method, which attempts to call requestFactory.getRequestTransport().send(...). requestFactory.getRequestTransport() returns NULL so it throws a Null Pointer Exception. Do I need to configure the transport somewhere? I didn't see anything in the documentation or the Expenses sample app. The portion of my code that is initiating this is (~ line 60) in: http://code.google.com/p/eatright/source/browse/trunk/EatRightApp/src/com/eatrightapp/publicweb/client/activity/UserAccountsActivity.java On Nov 17, 6:28 pm, Thomas Broyer wrote: > On 17 nov, 21:06, Nicholas wrote: > > > > > > > > > > > I am working on a small GWT app (I have used GWT in the past but it > > was a while ago), trying to learn the new MVP and RequestFactory.

Re: Request Factory Entity Relationships Lazy Loading
The problem with this is you will end up writing a lot of code to get
the whole object back. It makes a complex Data Access layer and makes
me wonder is it worth using a relational database. If I have to fetch
relationships separately (in either layer) why not use a key store
database.

If I understand you correctly, you'd like to have a glasspanel above
the "previous activity" while the "new one" starts? (until it calls
AcceptsOneWidget#setWidget to "reveal" itself) ?
IMO you should do this on your AcceptsOneWidget itself, not from
within your activities:
final SimplePanel realDisplay = new SimplePanel();
myActivitymanager.setDisplay(new AcceptsOneWidget {
public void setWidget(IsWidget w) {
if (w == null) {
// show a glass panel
} else {
// hide the glass panel, then:
realDisplay.setWidget(x);
}
}
});

Re: GWT Hosting
Hi You really should give a second chance to GAE: - space can go very high if you are willing to pay as you go - document upload is possible via BlobStore (I do it in one of my apps) - I would emphasize extremely detailled monitoring for which i know no equivalent by other hosters. Then, you will get scalability for free. The feature that is the most unsual at beginning: the datastore.

Manipulating UiBinder backed DockLayoutPanel regions with Java code
Hello Everyone, I have a DockLayoutPanel declared in UiBinder, with a corresponding Java view class. Is there anyway to manipulate DockLayoutPanel's regions from within Java code ? DockLayoutPanel UiBinder has regions: ... from Java code I want to access WEST region and manipulate it : (hide it/remove it) the only way i can think of is to write the entire DockLayoutPanel in Java code (no UiBinder). because DockLayoutPanel Java API has a lot of methods for dealing with regions, but it doesnt appear to be the case with UiBinder.

@UiField SimplePanel westPanel; westPanel.getWidget().setVisible(FALSE); But, this may not behave as you intend. Maybe I'm missing something in your question...

Re: Manipulating UiBinder backed DockLayoutPanel regions with Java code
I tried that, but it appears although westPanel becomes hidden (as expected setVisible(False)), the west region still takes up space. My guess is since in UiBinder regions must be explicitly sized, eg: hiding/removing a SimplePanel within a region does not mean the region itself is hidden//removed ? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Request Factory Entity Relationships Lazy Loading
IMO, this problem is not really GWT related but standard hibernate/jpa behaviour. Either you define your relationships as lazy, which means that they are not loaded when the parent object is loaded, or you define the relations as eager fetch. The best practice is lazy load and then load the needed relationships on a adhoc basis using Hibernate.initialize(donor.getDonations()) to fetch them. So you want the donations to come with the donor, initialize that relation during the transaction. Outside the transaction, any relation that was not loaded will throw a lazy load exception when you read any out of these related objects. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: application gets reloaded
Just to add further, it works fine in IE8 but not in IE7, so after
implementing the solution, it only reloads the application if
after that action I redirect it to another page e.g.
My Account
on action if I redirect it to say another page e.g.
History.newItem("login");
view changes to login without any reload and then automatically it
changes token back to my Account and reloads the application at this
stage.
Any suggestions?
Thanks.

Re: Manipulating UiBinder backed DockLayoutPanel regions with Java code
>From http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html#Design (scroll down to "Child Widget Visibility"): The Layout class has to wrap each of its child elements in a "container" element in order to work properly. One implication of this is that, when you call UIObject.setVisible(boolean) on a widget within a LayoutPanel, it won't behave quite as expected: the widget will indeed be made invisible, but it will tend to consume mouse events (actually, it's the container element that is doing so). To work around this, you can get the container element directly using LayoutPanel.getWidgetContainerElement(Widget), and set its visibility directly: LayoutPanel panel = ...; Widget child; panel.add(child); UIObject.setVisible(panel.getWidgetContainerElement(child), false); Hope that helps!

That was my point about it "not working as expected" 1. You might want to consider the splitter-type panels. 2. Maybe you want a different widget as a child of the SimplePanel, maybe an accordion? 3. You may want to implement a mix of Horizontal and Vertical panels as children of an HTMLPanel. Child widgets in those panels will show/hide as you want. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: design pattern for common functionality between Activities
Hello Koen,
I never used Requestfactory so I do not know if it is similar to RPC. In my
case, all my RPC Services can send a ServiceRemoteException (declared in
Services interfaces). (ServiceRemoteException is a custom exception that I
extended for my needs)
@RemoteServiceRelativePath("GWT.rpc")
public interface MyRemoteService extends RemoteService {
public void myRemoteMethod() throws ServiceRemoteException;
}
When There is a security exception (I am using a framework to manage
security checks called Shiro. http://shiro.apache.org/. I plugged it over
Guice and its AOP mechanism. Like this I can use special annotation on my
methods like @RequireAuthentication, @RequiresRole("role"), @RequiresGuest,
... and every time that a user try to access a method without the correct
permissions, a shiro exception is thrown.)
All Security Exception are caught by a global server exception catcher. (I
extendend the method processCall of the RemoteServiceServlet class for
this).
When a Shiro Security Exception is caught, I create a new
RemoteServiceException with some extra parameters that contains the security
exception type for the client.
Now, on the client, with RPC call, you calls methods with something similar
to this :
myService.myRemoteMethod(new AsyncCallback() {
@override
public void onSuccess(Void v) {
}
@override
public void onFailure(Throwable t) {
}
}
When a security exception occurs, the client code will execute the onFailure
method. Here you can manage how to handle your exception
onFailure(Throwable t) {
if(t instanceof RemoteServiceException) {
ExceptionType type = ((RemoteServiceException) t).getType();
if(type == SECURITY_AUTHENTICATION) {
placeController.goTo(new LoginPlace());
}
}
}
Now, maybe that you do not want to write this code in every onFailure(), so,
you can extends AsyncCallback class.
public abstract class ManagedAsyncCallback extends AsyncCallback {
@override
public void onFailure(Throwable t) {
// .. write your common security exception management here
}
}
then, when calling a service, you only have to override the onSuccess() in
quite every case, except in special situations.
myService.myRemoteMethod(new ManagedAsyncCallback() {
@override
public void onSuccess(Void v) {
}
}
I hope that it can help you :)
I do not know if RequestFactory is using somethig similar (onSuccess,
onFailure).
Thanks.

Re: GWT client-side thread or asynchronous call ?
If you really want to stick with the client side and want to have an async-like experience you could also use a Timer to trigger the search. Schedule the Timer as soon as the user begins to enter his search and cancel + re-schedule it on every key hit. This way the blocking search will only start as soon as the user has stopped typing for a specific amount of time. You will have to try and check what is a reasonable schedule time. This should work I think.

Re: GWT MVP and RequestFactory
I am having a very similar problem - NullPointerException when I call
fire() (the NPE is in AbstractRequestContext.doFire()). So I am
wondering if you have found a solution to your problem.
The code with the fire() is:
CommitmentSystemRequestFactory requestFactory =
GWT.create(CommitmentSystemRequestFactory.class);
requestFactory.commitmentRequest().countCommitments().fire(
new Receiver() {
@Override
public void onSuccess(Long response) {
Window.alert("Done!");
}
});
My CommitmentRequest class has:
@Service (Commitment.class)
public interface CommitmentRequest extends RequestContext {
Request countCommitments();
My Commitment.java class has:
public static long countCommitments() {
}
Some other notes...
* I have also been going through the Expenses sample app, both the
description at:
http://code.google.com/webtoolkit/doc/latest/DevGuideRequestFactory.html#proxies
and the sample code.
* I am NOT using JPA. My first learning project for GWT/GAE was with
JPA, but now I wanted to try the RequestFactory and then add
Objectify.
* I am NOT using MVP. I just don't yet have the critical mass of
brain cells necessary.
Thanks for any updates or advice...

Re: GWT MVP and RequestFactory
As is typical - after working on this for hours, I think I found my
problem 10 minutes after posting. Since I am trying to avoid MVP (for
now, until the brain cell count improves), I had not initialized my
RequestFactory. Adding:
final EventBus eventBus = new SimpleEventBus();
requestFactory.initialize(eventBus);
has moved me past my NPE. Into other errors of course...

Which the same as returned by JsDate.toLocaleString()
or plain JavaScript :
var datum = new Date();
document.write(" locale string = "+datum.toLocaleString());
All findings are also the same when using IE8 instead of Firefox.

Re: All I Want for Christmas is a powerful Widget Library from Google !
Thanks all for your support of GWT. We're really glad that what you've seen so far makes you want even more, and let me officially acknowledge here that the GWT team very much understands that you want a powerful widget library. That's why we created the powerful new CellWidgets in 2.1 (in time for Christmas, you may note) and are dreaming up new widgets for future releases also. Having said that, the GWT team at Google generally chooses to focus on the really hard problems such as compiler optimization and new features like RequestFactory while leaving the easier problems such as Widget creation (which is easy, in part, because of our focus on the hard problems) to the open source community. This is not even so much about the effort required to create new widgets as it is about the effort required to support them since that's where browser differences tend to be the greatest. In many cases, Googlers have contributed open source projects like gwt-dnd for drag and drop support (Fred Sauer) and GQuery (Ray Cromwell). But we don't think it's too much to ask everyone to put in a little effort extending and styling widgets in exchange for totally free, open source software that lets you run no-compromise AJAX on all modern browsers. Please do continue to share your Widget creations via the various GWT galleries on the Web! /dmc David Chandler Developer Programs Engineer, Google Web Toolkit http://googlewebtoolkit.blogspot.com/ On Sat, Nov 13, 2010 at 1:48 AM, zixzigma wrote: > GWT with its powerful set of features, make Large Scale Ajax software > development possible. > > from Java to JS compiler, all the optimization, code splitting, MVP, > Guice and Gin, new data binding features, > and one can go on and on ... > > However one important aspect seem to be neglected for years and not > aknowledged by GWT team is > the absense of a powerful Widget library. > > The widget set provided by GWT is very basic, and does not include > many many widgets needed to make more complex UI interaction possible. > > Drag and Drop (Tree for example or Grid, Filter), Calendar, Combo Box, > Complex grids (sort, filter, etc) to name a few. > > All the effort that goes into crafting a well architected and tested > app goes unnoticed unfortunately cause its about First Impression most > of the time ! > if you invest hours and hours to get the basic browser history > working, all the design for testability etc, > but dont have a pretty looking front-end, its just not fair ! > > We often see posts here and on other forums from developers requiring > more advanced widgets to develop their apps. > > there are alternatives out there, SmartGWT, Ext-GWT. > They are great, lots of eye candy, but they encourage a more desk-top > style apps on the web, > which goes against Google best practices that says not to turn web > apps into desktop-like apps). > also third-party libraries dont fit well with MVP, API inconsistency, > they are also are hard to customize beyond the provided themes. and > some of the other open-source ones are too experimental. > > You can argue that well go create your own. but that does not make any > sense at all. > if GWT is for Large Scale applications, does it make sense that > developers spend their time experimenting with where to position close- > icon on a Tab ?! or adding maximize/minimize to a dialog ? > what about these ubuquitous Callout Tooltips ? or implement drag and > drop on a tree which is going to be a maintanance nightmare down the > road ?! each project creating their own in-house widget library ?! and > test it ? > > > an alternative could be to use GWT along-side JQuery/YUI, because > there are hundreds if not thousands of variation for each plugin you > can think out there. but does it make sense to do all the optimization > in GWT, only to load additional JS Libraries to use plugins on top of > them? > > Google acquired Instantiations(GWT Designer) a while ago, which was > great news, > although many are waiting for them to add UiBinder feature(still in > beta), it was a great move by Google. > > I was thinking if Google Team is busy with the architectural aspect of > GWT, why not invest in or acquire a company to work on a powerful and > complete Widget Library to put others to shame.

CellList -- is prefilled sizing possible?
Hi there, I've been using the SmartGWT library mainly for the ListGrid (which is similar to the CellList). The problem is, the SMartGWT library comes with a massive footprint (even when it is gzipped). The performace of our site has been terrible ever since we introduced the ListGrid, but on the other hand, it is pretty much a requirement. I was very excited to see the CellList Widget bundled with the 2.1 release, but looking at the samples, I find the fetch behavior a little awkward. First the List may fetch, say, 50 rows. The scrollbar will represent a list with 50 rows. When you scroll to the bottom, new rows are fetched and the scrollbar contents area increases to accommodate the new rows. This variable sizing seems awkward. I know the total number of rows my list can have. Is there any way I can pass this information on to the CellGrid and have it prefill the unseen areas with blank space and update them when they are scrolled to?

Re: CellList -- is prefilled sizing possible?
The scroll bar is separate from the CellList. Its actually an implementation of a pager and is more a proof of concept until we have a proper infinite scrollbar. You can prepopulate a CellList with nulls or default values until you have data available. As far as populating them when you scroll into view, you would need to implement your own scrolling pager to figure out which data should be visible, but you can push data into a CellList at any time. At some point we will probably implement an infinite scrollbar, but it isn't on the agenda in the near term.

Re: CellList -- is prefilled sizing possible?
Thanks for your quick (and detailed) response; I really appreciate it. >From what I can tell looking at the API, the pager is built right into the CellList (as opposed to being a separate widget that can be optionally provided). Am I missing something? I don't mind mucking around with the source code (I've done it already with SplitLayoutPanel, which has a hardcoded splitter width/height that I needed to change). I just want to make sure that I go about this the right way. I am fairly determined to get rid of external dependencies to SmartGWT for many reasons. So it is very likely I will need to implement some form of infinite scrollbar. Thanks, Andrew Arnott On Nov 18, 4:02 pm, John LaBanca wrote: > The scroll bar is separate from the CellList.

Re: GWT Obfuscation crashes iPad Safari browser
One thing I would highly endorse with such a large compiled project is to gzip it if you are not doing that already. You might find that doing that also fixes the iPad Safari issue (if it is line length, the zipping might allow the iPad browser to look at the file in a different way). --Andrew Arnott On Nov 16, 3:03 am, tbb wrote: > Hi all, > I discovered a strange problem with a pretty big GWT application.

The GWT compiler already only compiles JS that's reachable from your program, but you can sometimes find ways to use more common code: i.e., if you're doing something with java.util in one class, do it that way consistently everywhere in all classes so you get the max benefit of the downloaded java.util bytes. > thanks for looking :) You're welcome.

Re: CellList -- is prefilled sizing possible?
The scrollbars are a separate widget called ShowMorePagerPanel. CellList doesn't have scrollbars by default. http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/showcase/src/com/google/gwt/sample/showcase/client/content/cell/ShowMorePagerPanel.java If you look at the constructor, you'll see that we add a ScrollHandler that modifies the visible Range when the user scrolls. If you want to implement an infinite scrollbar, you would need to do something similar, which means you need a way to map scroll position to row indexes. It can be pretty tricky to get it right, but you can probably find a lot of examples online.

This looks like a good example for a basic dialog not a separate
activity that needs to be render its view in a glasspanel. So let me
try an give a better example.
There are actually two scenarios which I believe the invocation of
showWidgetr(null) in myActivityManager.onPlaceChange(.. ) trips me
up.
Scenario 1) Consider an app with a dozen or more independent
Activities. Let's say one of these independent activities will
manifest in a popup ( layer.. glasspanel... ). This is not a simple
dialog but an independent activity and it may appear above any of the
other activity places in the app. Using the pattern described in MVP
part I or part II this was fairly straightforward because the widget
representing the container was not touched until the Presenter
responsible for rendering itself as a glass panel was ready to
initialize its view.However with the latest mcv 2.1 framework ,
the container is cleared as a result of the request to go to the new
place . See show showWidgetr(null) in
myActivityManager.onPlaceChange(.. ) . As a result, the glasspanel
renders over a blank page.
Scenario 2) Consider View1 in Activity1 with a goToActivity2
button. Activity2 makes a fairly long , albeit async, rpc call so
a progress indicator is required. In addition , the View2 served by
Activity2 has nothing interesting on it except for the data coming
back from the async rpc call.Therefore it would be better to show
the progress indicator on View1's goToActivity2 button. Using the
pattern described in MVP part I or part II one would simply call the
container.setWigdet(view2) in the onSuccess method of the RPC
call. However with the latest mcv 2.1 framework , the container
is cleared as a result of the request to go to the new place . See
show showWidgetr(null) in myActivityManager.onPlaceChange(.. ) . As a
result, View1 clears immediately and an blank page is shown until
the rpc comes back in Activity2.

webappcreator with -maven and Eclipse: output directories don't match

I'm quite new to all this so hesitant to say it's wrong but it looks like it is. I see 2 problems. First there's the duplication of .class files which wastes resources. Second is the possibility of them getting out of step and the feedback in the Eclipse editor of problems with the source might be wrong.

Hey Chris, A few questions: -what operating system are you on? -I noticed that you have the gwt-user.jar and gwt-dev.jar explicitly on your build classpath. Did you add those entries?

The gwt-*.jar dependencies were automatically added after - to answer your last question - I configured the 2.1.0 SDK in project properties after upgrading the SDK/ plugin. I'm fairly certain gwt-dev.jar shouldn't be a compile-time dependency, right? In any event, building/GWT-compiling work just fine, the only problem is starting up dev mode. I think I can reconfigure maven to explode the resources zip file to src/main/webapp instead of target/ before compilation so this likely won't be a long-term problem, but its still a change from the behavior using the 1.3.3 plugin.

Re: GWT MVP and RequestFactory
Richard, I was missing that initialization to requestFactory as well.
I had to add that, and I had to add the following sections to my
web.xml:
requestFactoryServlet
com.google.gwt.requestfactory.server.RequestFactoryServlet
remoteapi
com.google.apphosting.utils.remoteapi.RemoteApiServlet
remoteapi
/remote_api
requestFactoryServlet
/gwtRequest
In addition, I added the appengine-tools-api.jar files to my web-inf/
lib folder.
I had to add the following to my apps gwt.xml file:
Finally, I added json.jar to my web-inf/lib folder. I'm not sure
where this file originated, but I finally tracked down a copy at:
http://google-web-toolkit.googlecode.com/svn-history/r7687/trunk/bikeshed/war/WEB-INF/lib/json.jar
Now the app seems to be running without any errors. I think some of
this needs to go into the RequestBuilder/MVP documentation. If it's
there I completely overlooked it.

Re: GWT MVP and RequestFactory
One more thing I forgot to mention. You have to add an init-param to
the requestFactoryServlet to identify your implementation class for
the user information class. (This is in your web.xml). Mine looks
like this.
requestFactoryServlet
com.google.gwt.requestfactory.server.RequestFactoryServlet
userInfoClass
com.eatrightapp.server.domain.GaeUserInformation
Without that specified, your login widget will always show the user as
"Dummy User" and the logout link will not be functional. Now that all
this is in place, mine is completely working as expected.
Thanks,
Nick
