SimpleRadioButton getValue() ?
Greetings,
I have the following snippet :
SimpleRadioButton r1 =
SimpleRadioButton.wrap(DOM.getElementById("radio1"));
r1.getValue(); // expected method does not exist.
DOM.getElementAttribute(r1.getElement(), "value") ; // This works
fine.
My question is : is this the intended way to use SimpleRadioButton ?
Why not r1.getValue() ?

FF, LayoutPanel and
Hi, FF has a defect regarding absolute positioning while using (e.g editbox) or . I found a workaround. When you are affected by this bug and don't want to wait until Google put it into an official release, add the files of issue 4338 to your own build of gwt and recompile. http://code.google.com/p/google-web-toolkit/issues/detail?id=4348 Stefan Bachert http://gwtworld.de -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Found bug in PopupPanel in IE6/7/8
People, I reported a new issue on GWT in IE (6/7/8) where I no longer get keyboard events when closing down a PopupPanel by clicking on a textbox. In case somebody is bored and wants to fix it ?

GWT+Spring
Hi all I am working on an Simple Spring app just an index page which takes the username and password and responds with an success or failure page... If successful I have given a href there in other words an request which takes me to the index page of the GWT app. After combining both of these Spring and GWT the Spring part is working fine but I am facing some prob with GWT. I can see that the folder structure is correct. When I do a GWT compile I see that all the files sit in the right position just as when we do a GWT compile for a normal GWT app. I see the static contents of the GWT index page but I dont see the dynamic content (java converted javascript). The id nameFieldContainer is used in the entry point class which after the GWT compile should be present in one of the cache.html whose mapping should be there in nocache.html. Only if I can retrieve this, this will change into the text box or button as mentioned in the GWT entry point class. This is not happening. Can some one here tell me where I am going wrong.. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: What's the best/easiest way of doing server-side persistence with GWT?
Ah yes! Except that I want to be able to get persistent things onto my client side without too much conversion or trouble (i.e. the same objects client-and-server-side using the same language, and the same class definitions). What are my full range of options for this, anyway? And which is the best one for the purposes I've mentioned?

Re: What's the best/easiest way of doing server-side persistence with GWT?
Although your question has (almost) nothing to do with GWT... we're working on a GWT + JavaEE application, and evaluated several alternatives regarding this problem. We had two winners, both of them using of course JPA with Hibernate provider: 1. Use Gilead to transform your persistent entities and send them to GWT 2. Use DTOs, and use Dozer to transform from / to domain objects / entities In our case we chose DTOs / Dozer over Gilead because we favoured layer separation, encapsulation and security over development ease. YMMV Best regards José On 20 mayo, 10:54, Navigateur wrote: > Ah yes!

Performance issue with large object model
Hello
On our current project we have a fairly large database model mapped
thru Hibernate JPA annotations: around 150 entities.
Those JPA entities have a lot of @ManyToOne, @OneToMany, @ManyToMany
inter relations.
On the server side Hibernate lazy loading is active and managed
correctly so that no extra unneeded collections are fetched to the
client.
I’m using Gilead in stateless mode with all JPA entities extending
java.io.Serializable and net.sf.gilead.pojo.gwt.LightEntity
So back to the client side, I created a simple RPC Service
@RemoteServiceRelativePath("country.rpc")
public interface CountryService extends RemoteService
{
Country findCountry(String countryId);
}
public interface CountryServiceAsync
{
void findCountry(String countryId, AsyncCallback
callback);
}
The Country type has several Collection fields whose type have as well
their own relations. But, again, thanks to lazy loading, those
collections are empty.
Problem arise when I try to create the service using Development Mode
(Run As Web Application in Eclipse)
CountryServiceAsync countryService = GWT.create(CountryService.class);
GWT.create()'s goal is to create a client proxy for the remote
service's server side implementation.
Extract from the "Development Mode" console:
12:30:18.664 [DEBUG] [project] Invoking
com.google.gwt.dev.javac.standardgeneratorcont...@904576
12:30:18.664 [DEBUG] [project] Generating client proxy for remote
service interface
'com.company.project.client.services.CountryServiceClient'
12:30:18.664 [DEBUG] [project] Analyzing
'com.company.project.client.services.CountryServiceClient' for
serializable types
12:30:18.664 [DEBUG] [project] Analyzing methods:
12:30:18.664 [DEBUG] [project] public abstract
com.company.project.server.dom.Country findCountry(java.lang.String
countryId)
12:30:18.664 [DEBUG] [project] Return type:
com.company.project.server.dom.Country
12:30:20.648 [DEBUG] [project] com.company.project.server.dom.Country
12:30:20.648 [DEBUG] [project] Finding possibly instantiable subtypes
.
.
.
Then a huge tree a dependent subtypes that qualify for serialization
is built.
At this point, GWT.create method returns after around 5 minutes !
Nothing mentions in the documentation that Serialization performance
depends on the number of imports of a types, including imported types
of its children:
http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.html#DevGuideMakingACall
If you read this link:
http://sinnema313.wordpress.com/2008/11/16/performance-tuning-a-gwt-application/
It mentions that "Serialization is slow: (...) Serialization
performance appears to be proportional to the number of objects, not
just to their total size."
I see 2 possible solutions:
- Cache serializable types (gwt.rpc file) and load them with the
module, but I don’t know if it's feasible with current GWT API
- Use DTOs and Dozer to drastically denormalize our model object and
limit the number of inter relations between types.
Did any of you already faced this performance problem ?
Thanks
Fred

Re: Performance issue with large object model
I'd recommend using DTO's. Whether you use Dozer or not is secondary.
The motivations for this approach are in this thread -
http://groups.google.com/group/google-web-toolkit/msg/f9290388bbf5a5f8. In
general, you want to keep your UI Model (i.e. DTO) separate from your Domain
Model (hibernate entities). And Performance is not the only reason for this
- there are going to be times when you don't want to some information to the
client due to security/privacy concerns.

Client side dynamic configuration/properties
Hi, What is a good way to get dynamic configuration information to the client? I've an application that has some configuration parameters that we need client side, which include: - Configurable dates fetched from a database. - Certain interface heights/widths, preferably configured in some easy .properties file. - Labels for weeks fetched from a database. Looks like the Constants interface is not a good match for this since a recompile seems necessary on every change. I was thinking about creating some Configuration object that gets fetched on application start (server fills it with the necessary data), and which is then available through some singleton/static variable construct. Disadvantage is of course that singletons are sometimes discouraged, and that it's more work to code than an out of the box solution. Any thoughts on this? -- Regards, Mike Noordermeer m...@normi.net -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Client side dynamic configuration/properties
You would simply write out, server side, a Dictionary JS object and then pick that up in the GWT code. See http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/i18n/client/Dictionary.htmlfor more details.

Re: Client side dynamic configuration/properties
You need to create some .properties file on the server side. And every client must make request for it. If it is on the client side it could be loaded as TextResource, but on every change the gwt project must be recompiled, which does not make it very dynamic. I recommend you to use server side .properties file and load it as map or something. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

How can I clone an object in GWT?
I tried to use History class to manage the handling of the back/forward
functioning of the browsers. In order to do that, I need to save the screens
with state to a collection, such as a HashMap, hmap.
For example, the screen is represented by a Composite object, compObject,
which contains a widget object: wgtObject. Every time when I said that the
screen was changed, it implied that the only the wgtObject was changed. When
I used the History to do that, the code is like,
Hostory.newItem(screenName);
hmap.put(screenName, compObject);
However, since the compObject is the same instance, on the onValueChange()
public void onValueChange(ValueChangeEvent event) {
String screenName = event.getValue();
Composite composite = hmap.get(screenName);
if (compObject != null) {
RootPanel slot = RootPanel.get("mainPanel");
slot.clear();
slot.add(composite);
}
}
even the code turned to different screens, the same screen remained
unchanged. The reason is that the compObject rather than wgtObject is saved
to hmap!
But I need to save compObject with its state to hmap. So I need to clone the
compObject before saving it to hmap. Since there is no Object.clone()
available for GWT, how can I do that?
Thanks,
Mike J.

Re: What's the best/easiest way of doing server-side persistence with GWT?
Thanks José! But don't they still require you to do the "hibernate- mapping" xml thing? Isn't this cumbersome for complex object structures? Or is there a way of being able to play with your object structure without having to change the hibernate-mapping xml every time (i.e. a default automatic behaviour for all objects, which also updates the data-store to reflect object-structure changes in the code)?

Re: What's the best/easiest way of doing server-side persistence with GWT?
You could try OpenJPA, which can now largely be done using annotations rather than xml, or if you are not needing to use SQL DBs you could try one of the object dbs like db4o.

Re: What's the best/easiest way of doing server-side persistence with GWT?
JPA/Hibernate supports annotations, so you don't have to fiddle with xml files any more; and JPA/Hibernate has adopted the "sane defaults" and "convention over configuration" policy, so unless you want to take control of your mappings (something you should do if you're doing anything serious) most of the times it's enough to annotate the persistent class with the @Entity annotation. Anyway, if you're handling complex object structures, it's way more cumbersome to handle persistence by hand, instead of using a ORM framework. If you want to have automatic update of the database, Hibernate tools is able to generate the database schema from your mappings. I suggest to take a look at Maven, Maven Hibernate plugin, JBoss Tools, and Spring Roo. Haven't worked with the later, but GWT has just made a coordinated release with Spring Roo and I think it may be quite interesting for you. I hope this isn't getting too much OT...

Re: How can I clone an object in GWT?
In general, trying to store the application state by storing the
widget itself is a bad idea, would be very expensive and of course
with no deep clone doesn't even work. Better is to extract just the
data needed to reconstruct the widget state and store that, then
reconstruct the state on history changes. Depending on your app
design you may already have methods to do this, ie to build the
initial widget contents or to send them back to the server.
Also as an aside, note that History.newItem() will actually call the
history change event, which in this case would immediately try to
reconstruct the widget with the data you just captured (or are about
to capture). Be sure to add a flag or something so your change
handler does not do this unnecessary restore when you are manually
adding history items.

Re: How can I clone an object in GWT?
Understand what you suggested. Thanks.
The reason for doing this way is based on the following considerations,
1. The screens are saved as objects completely on the client side. No
client-server networking traffic issues during the storing and reloading
process. Even in multiple concurrent client environment, it would not cause
problem on server side. the only expense is on the individual client ;
2. Extracting the data and saving the data only would be a good idea, just
like sending bare data rather than sending a serialized object as a whole
with overhead across the network. The problem is that reconstructing the
screen is not a simple job, especially for a rich component screen. Thus I
would like to borrow the idea of the object serialization scenario.

Re: What's the best/easiest way of doing server-side persistence with GWT?
Wow, thanks José and David! I'm new to "tools" so I'm a bit nervous about using them (although I probably shouldn't be) whereas db4o offers straightforward code for persisting objects. Are there any disadvantages to using db4o instead of ORM with tools? db4o seems intuitavely the best option for me right now, but could I be wrong? I thank David for bringing it to my attention, it looks VERY interesting, and under active development, although the queries are currently reportedly slow, but when that is fixed, is there a reason why it shouldn't supercede RD and ORD for new projects?

Re: What's the best/easiest way of doing server-side persistence with GWT?
Although you could think they're the perfect solution for persistence in OO languages, object databases haven't taken off, so if you're doing anything serious I would be cautious about using them. I don't know of any big application in production with an OODB. Maybe we're too used to relational databases... Take a look at Spring Roo, I think you will like it.

Be advised that Gilead used to be called hibernate4gwt and still supports only hibernate.

Re: How can I clone an object in GWT?
Well of course there's no need to send the state to the server, just capture it and maintain it on the client (of course the user can't copy the link to send to someone else, just use it locally). Just mentioning that if you already do send the data to the server for other reasons, you already have the capture state methods done. As for reconstructing, I don't know your app but would be surprised that it would be too difficult - I've done this lots on various complexity of widgets, and while a little tricky in some cases, once done it makes the programming model much easier.

AuthSub vs. history tokens
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
I'm trying to log in to a Google service by using AuthSub. This works by
redirecting the user to a Google login page, which then redirects back
to my app after login with a cookie in the #... section of the URL.
Unfortunately this appears to conflict with my app's use of hisotry
tokens, which are *also* stored in the #... section of the URL. So when
my app reloads I don't know what page the user was previously looking at.
It would appear that traditional Javascript apps don't have to worry
about this as AFAICT they don't use history tokens in the same way as GWT.
Does anyone have experience of using AuthSub with GWT, and how did you
work around this?

GWT StockWatcher tutorial app with JSON runs on Firefox but not IE
I have completed the GWT JSON tutorial (http://code.google.com/ webtoolkit/doc/latest/tutorial/JSON.html) but ran into trouble. The servlet class coded therein (JsonStockData) works fine in Firefox (v 3.0.18) but in in IE (v 7). The tutorial directed me to run the servlet directly from the address bar in the browser, as follows: http://localhost:/stockwatcher/stockPrices?q=ABC+DEF. When I do that in Firefox, it generates a JSON script including stock price and change information for fictitious stocks ABC and DEF. That proves that the servlet will work correctly when invoked from the GWT code in the StockWatcher class. And indeed it does work - when I type in any fictitious stock symbol, the servlet generates quasi-random stock price data and returns it in a little JSON file which is then included in the output data. However, when I try both of those things (running the servlet separately and running it as part of the StockWatcher application) I get "HTTP method GET is not supported by this URL" messages displayed. That's an HTTP 405 error. I've looked up that error on Google, and the concensus seems to be that it occurs when the doGet() method is not defined in the servlet. I'm sure that would be applicable if there was no doGet() method, but I do have a doGet() method, copied in from the tutorial code. I have not tried this with any other browsers. Any idea what's wrong? Is there some setting in IE7 that is preventing the GET method from running? I'm not posting any code here because it's all taken from the tutorial. However, is if there is any specific thing you want to see, let me know and I'll post it.

Problems w/ Switching Off App Engine
I'd been using App Engine since that is the default setting. However, I need to turn that off because I need access to local file storage on the server side and I will be moving to a physically secure environment. I should also note that I'm a newly minted GWT user. My steps to the error are: 1.) In Eclipse right click project->properties->Google->App Engine- >Uncheck Use Google App Engine 2.) Click run debug button 3.) Window pops for debug view. I click Yes 4.) In DevModeBase.class process is halted at "shutDown" in method "run()" 5.)

suggest box - how to override default behavior
Hello Team, I cant find my initial post on this topic, so this might be a re-post for some of you. I have a SuggestBox in my gwt app that needs to add an additional parameter to the request that is sent to the server for auto- completion. How can i do this? There is no method to add additional parameters to the SuggestOracle. I tried sub-classing the SuggestOracle, but most of the methods in that class are default access and if I sub-class the SuggestOracle.Request class, the RPC mechanism fails to make the request... The only other way is to modify the query in the requestSuggestions method... but that does not sound clean to me... sounds like a hack... So, what is the best way to add parameters to an ajax request made by the SuggestBox?

Help integrating GWT with existing Eclipse J2EE Tomcat project
Using the Eclipse plugin I created a new GWT project. I was able to run it in development mode (via the 'Run As Web Application' command. I was able to run the auto-generated test app successfully. Note that I named the test project testGWT. I have an existing project in Eclipse which uses Tomcat. I need to integrated GWT into this project. I followed the instructions here... http://code.google.com/eclipse/docs/existingprojects.html I then copied the source code, html and css from the test project into my project. I also copied the servlet entry into my web.xml. I restarted Tomcat and noted that the /testgwt directory was created/ I then tried to hit http://127.0.0.1:8080/TestGWT.html?gwt.codesvr=127.0.0.1:9997 in my browser, which returned... "Plugin failed to connect to hosted mode server at 127.0.0.1:9997" (I tried changing 127.0.0.01 to localhost, which did not help.) At this point I thought I would simply compile to Javascript and test that way. I right clicked the project Google > GWT Compile. I get the dialogue which shows my entry point class. When I click ok I get the error "GWT compilation failed" with no details as to why. I confirmed that the gwt-servlet.jar file is on my classpath and Eclipse is notifying me of no compilation problems prior to the GWT compile attempt. I think I must be missing something fundamental.

Applet integration
Hi
We are designing an application that needs client-side digital signatures.
This is going to be accomplished via a signed java applet.
I know I can add the applet code instantiation via
HTML applet = new HTML();
applet.setHTML(createHTMLApplet());
RootPanel.get().add(applet);
This works well but as this is our first GWT app we have some questions:
- The applet, after being initialized calls some javascript methods to notify
it has been loaded, and do the same after client-side signature has finished:
function onInitOk(){ ... }
function onSignOk(signature) { }
function onSignCancel() { }
function onSignError(erorr) { }
How can I accomplish this? JSNI? JavaScript Overlays?
- It would be really interesting to comunicate directly with the applet via
javascript, f.i., leaving in some javascript variables the data to be signed
and retrieve the signed data when the applet calls the onSignOk function
This is also possible?
Thanks

FileUpload Look-And-Feel
I understand that the FileUpload widget only wraps the HTML tag and that I can't control how it looks. The problem I'm having is that the look-and-feel I'm getting is not that of the tag. I'm using IE 8. If I build a HTML form like this: The widget on the page will not allow text entry. If I create a GWT FormPanel with a FileUpload Widget (such as the one in the Showcase) it does. So somehow GWT behaves differently. I even tried creating my own custom widget, using DOM.createElement() to build the input tag, and I still got the non-standard behavior. Why? And is there a way to have the widget behave the way the inherent HTML widget does? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

suggest box - how to override default behavior
Hello All, I am learning GWT and loving it too. In my app, I have a suggest box that needs to query the server for its suggestions. I have it working great when the query to be sent to the server is the text in the input box alone... however, i dont see any way to tack on an additional parameter to the query. Even if i sub- class SuggestBox, the method visibility in SuggestBox is all default which means i need to be in the same package as gwt. Also, in the sub- class for SuggestOracle, there is no clearly specified way to add query parameters to the query... there seems to be an opportunity to much with the request in SuggestOracle#requestSuggestions(Request request, Callback callback)... is that what is expected? If not, how is this done? Any pointers/help will be highly appreciated. Thank you!

Help with DatePicker
Hello everyone,
I am using GWT 2.0 and having trouble with the DatePicker. There is a
lot of conflicting information on the web about the GWT DatePicker
object, and I suspect most of it was written for GWT 1.6.
I am trying to implement a simple DatePicker (I was thinking something
along the lines of Expedia.com or Travelocity.com). I have it kind of
working--my DatePicker can populate my TextBox with the selected date.
However, if I click on the SAME date as selected, the DatePicker will
not disappear:
final DatePicker datePicker = new DatePicker();
final TextBox dateLabel;
dateLabel = new TextBox();
datePicker.addValueChangeHandler(new ValueChangeHandler() {
public void onValueChange(ValueChangeEvent event) {
Date date = (Date) event.getValue();
String dateString =
DateTimeFormat.getMediumDateFormat().format(date);
dateLabel.setText(dateString);
datePicker.setVisible(false);
}
});
datePicker.setVisible(false);
dateLabel.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
datePicker.setVisible(true);
}
});
// Set the default value
datePicker.setValue(new Date(), true);
searchTable.setWidget(0, 0, dateLabel);
searchTable.setWidget(0, 1, datePicker);
Since clicking the same date will not fire a ValueChangeEvent, the
picker stays. It seems to me there must be an easier, more standard
way of implementing the datePicker. I was thinking something like
what's already implemented in http://datepickerdemo.appspot.com/,
although I was unable to find/figure out how they implemented, or at
least more useful information on the DatePicker object in GWT 2.0.
Thanks so much in advance,
Pedro

Re: Applet integration
For the GWT-to-Applet communication, JSNI is probably all you need.
For the other side of the conversation you could do it with JSNI, but
an easier way may be to look at the gwt-exporter project and build an
'exported' API that the applet can call in native JS.
http://code.google.com/p/gwt-exporter/
The project site is sparse on doc, but the author's blog should help
you get started: http://timepedia.blogspot.com/search?q=exporter

Re: MVP Framework in GWT 2.1 M1 ?
Its actually quite a bit different than what they have talked about in the past. From a quick look I had, it appears to incorporate a bunch of scafolding code generation, dynamic binding etc.You can take a look at the bikeshed project in svn.

Re: MVP Framework in GWT 2.1 M1 ?
I think, the whole MVP with GWT thing is actually inspired by the talk given by Ray Ryan on last year's Google IO (see http://www.youtube.com/watch?v=PDuhR18-EdM). Currently, there are implementations available that do provide an MVP infrastructure and implement other patterns as well: - http://code.google.com/p/gwt-presenter/ - http://code.google.com/p/gwt-dispatch/ - http://code.google.com/p/gwt-platform/ However, it would be nice to see these features integrated into GWT directly, therefore I'm really interested in how Google itself implemented the patterns :-) I know that the announcement was just yesterday but it would be great to get more detailed information on the new features introduced in 2.1 (especially the new widgets and mvp). Regarding the demo given during the keynote, I'd also like to know how the automatic resizing for mobile screens takes place.

Are you posting to a different port on the same host? AFAIK, IE allows you
to post to the same port, but other browsers consider it a violation of same

Re: MVP Framework in GWT 2.1 M1 ?
Thanks for the link Paul - I'm afraid my answer overlapped with your first reply. I think we talk about two different features in 2.1: first, there is the data binding stuff that was shown in great length during the keynote and I agree that it seems to be originating form the link you posted. The other feature is the MVP infrastructure. To my mind, the MVP framework has nothing to do with the server side but is intended for a clean separation of concerns within the client layer. As far as I understand MVP, it essentially decouples the actual view code from the logic that handles the data (the Presenter), making the logic part a lot easier to test. Regarding the data binding part, there are some new classes that also appear in the javadocs of M1 (Cell-Classes, ListView, Pager etc.) but I haven't found anything regarding the MVP-Framework.

Compiling classes that refer to uncompilable classes
Hi, currently I create modules in order to access server-side classes
in my GWT client code. Until now all these classes have not referred
(directly or indirectly) to classes outside of the GWT JRE emulation.
However, now I need to be able to compile a bean with a reference to
javax.xml.namescape.QName. And in general I see how it might soon be
needed to compile classes with references to uncompilable classes
either because it's a third party class and we don't have the source
available, or it's a JRE class for which there's no emulation yet,
etc.
So I'm wondering if there's a way to use deferred binding to provide
the compiler with a "client-side specific" implementation of those
classes. The caveat of course is that the class containing the
offending reference to uncompilable code should not be changed. For
example:
class MyBean {
QName q;
MyBean(QName q) {
this.q = q;
}
}
Maybe something along the lines of ...
For what I read nothing of the like is possible, since for starters
the deferred implementation has to go through GWT.create(), but I'm
hoping there's another way I haven't thought about.
Thanks

I don't want to have strange bugs or other problems that will slow down the development... thank you. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: LayoutPanel
Be sure to read fully through http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html for various caveats and restrictions. In particular, if a layout panel is not directly parented by a widget that implements ProvidesResize, you must explicitly set its size (see "Using a LayoutPanel without RootLayoutPanel") Also there is an issue with TabLayoutPanel, but IE related: http://code.google.com/p/google-web-toolkit/issues/detail?id=4694&can=5 On May 20, 3:29 pm, Blessed Geek wrote: > I cannot get contents of LayoutPanel to display after > placing it inside a verticalpanel which in turn is > placed inside a TabLayoutPanel, > all thro UIBinder. > > Chrome would display a little bit but contents of LayoutPanel is all > blank for FF. > In standards mode. > > Any one else have trouble with LayoutPanel? > > Is LayoutPanel problematic and buggy and should not be used? > Any alternative? > > -- > You received this message because you are subscribed to the Google Groups > "Google Web Toolkit" group. > To post to this group, send email to google-web-tool...@googlegroups.com. > To unsubscribe from this group, send email to > google-web-toolkit+unsubscr...@googlegroups.com. > For more options, visit this group > athttp://groups.google.com/group/google-web-toolkit?hl=en. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: MVP Framework in GWT 2.1 M1 ?
There is the data bound cell based list and tree widgets they talked about. These are really independent of any mvp framework. However, there is also server/client side data binding support that is part of their new business application framework. The expenses application is very different from the mvp stuff shown to date. If you look at the bikeshed project in the 2.1 branch you can see the expenses application code.

Re: Is switching to GWT 2.1 safe?
I have a fatal compiler issue when trying to compile my application. They are working on tracking it down. Dev mode works OK. The only reason I am on it is because I want to try out the new cell views. I would hold off for a while if you can.

Re: Problems w/ Switching Off App Engine
Not to be crass, but doesn't that defeat the purpose of having a setting if I have to do that manually?

Re: Problems w/ Switching Off App Engine
Not a thing you'd be switching back and forth on frequently - either you're using GAE as your backend or not. In any case having the jars there shouldn't cause any problem, more likely something wasn't recompiled when switched - maybe try a clean build after turning off GAE.

Re: Problems w/ Switching Off App Engine
Clean->Compile->Run Debug Causes the exact same error. Another compatriot just chuckled at me for using GAE in the first place rather than disabling it right away.

There are some javadoc comments on the new classes.

Re: RequestBuilder.POST to PHP works in IE, FireFox, but not Chrome Response Status = 0
I'm not explicitly asking it to post to any specific port to my
knowledge. My url is http://www.mydomain.com/testing/login.php. The
site.html file and accompanying folder are in the same directory
"testing" as the php file.
I've seen alot of things about SOP, but I thought if they were on the
same domain I should be fine. Would each folder be a different port?
Also, I noticed its not a problem unless I navigate to the page with a
history token. i.e. (mydomain.com/testing.html#initialLogin) fails,
but mydomain.com/testing.html works.
Thanks for all your help.

Table Row Gaps
When creating a Grid, FlexTable, VerticalPanel, or any other type of table, I couldn't get rid of the gaps in the rows. The gaps would only appear in Chrome and FF, but not in IE6. They were very small gaps (about 3 pixels high). Nothing seemed to work, setCellPadding, setCellSpacing, css with padding, margin, border-collapse, ... Finally figured out changing the "doctype" solved it. The default was: When I changed it to: The row gaps disappeared! If there is a better way, please post.
