Re: GWT vs GWT-Ext
Hi All, For the pure-JavaScript side, I personally love Dojo Toolkit for various reasons: 1) Maturity of the toolkit over last few years 2) License (See: http://dojotoolkit.org/license) 3) Out-of-the-box Widgets 4) Features: Support for template-based widget, Django-templates, Offline support using Google Gears etc. Just fantastic. 5) Support (See: http://dojotoolkit.org/foundation) If you're looking for something on GWT -- you may have to wait. DWT - Dojo on GWT - is something that I am currently working on. But it's only a few weeks old, may take at least 3-4 months to have only the "Widgets" ready. -- Happy Hacking, Gaurav http://sf.net/projects/dwt http://eduzine.edujini-labs.com http://blogs.mastergaurav.com -- On Aug 28, 12:07 am, bwarner <[EMAIL PROTECTED]> wrote: > I would recommend steering away from GWT-Ext.

Re: GWT vs GWT-Ext
My experience is different, I used GWT-EXT with GWT extensively, You can check this example www.sample.gwt4enterprise.com. There were few issues with gwt-ext but current version is very stable, and it covers mostly all types of widgets. EXT-GWT is still in its initial versions and yet to add more widget. -Vivek --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Dynamic Evaluation
Hi Walden, > Sorry to disappoint. I'm not sure how or why you would port that to > GWT. Maybe someone else on the list can be of more help to you. If your query is as to why I would like to port Dojo for GWT, then there's a valid case for it. 1- I'm try to combine the power of GWT and Dojo. 2- I saw an initial interest in the community for this project. For instance, have a look at http://turtle.dojotoolkit.org/pipermail/dojo-interest/2008-July/032549.html 3- It opens up another option for Dojo users. Why not use Eclipse or Netbeans or any other Java IDE to develop Dojo based applications. Regarding the "how" of dojoAttachPoint, I think I've got a solution.

Re: GWT vs GWT-Ext
you could also give a shot to a couple of other pure GWT libraries: 1) ItMill (http://www.itmill.com/) 2) Ext GWT or GXT (http://extjs.com/products/gxt/) both are a bit less mature than the javascript-based ExtJs, but are quite decent. GWT 1.5 on its own is also starting to catch up in terms of widgets. Also projects like gwt incubator also provide a number of features that are missing in GWT core.

Re: how to send a dom document to a server
Hi,
To actually send the document:
try {
rb.send();
}
catch (Exception e) {
throw new Exception(e);
}
Again, the above assumes a CGI environment, not Java RPC. You'll need
machinery to handle the asynchronously handle the POST response. See
the GWT docs.

Re: Query : Synchronous calls in GWT
You can emulate synchronous behavior by following these rules:
1. Any RPC or other call has to be made at the end of a method/
function. Theoretically, the call may return before the method has
finished. Don't put any other code at the end.
2. Don't use Timers or make sure all Timers have stopped.
3. Disable all widgets or at least those that have listeners attached
to them. Re-enable them in a function that is called by onSuccess()
and onFailure().
If you stick to these rules I'm fairly certain that your application
state will not change while the RPC is being run, but you can still
use your browser for other things. Also, synchronous calls may look
like an option to you now, but you may want your app to do other
things in parallel in the future. That is not uncommon, believe me. By
then switching to async calls may be exponentially more difficult.
I recommend you put Thread.sleep(5000); in each of your
RemoteServiceServlet methods. Then you will see how grateful your
users will be if you use asynchronous calls right from the start.

Re: how to send a dom document to a server
Hi,
The following assumes regular CGI usage. If you're using Java RPC,
you'll use a different technique.
First, you're going to parse the source document via
XMParser.parse().
Document docQuestionnaire = XMLParser.parse(xmlData);
You may have more machinery around the above call whose purpose is to
put an XML string into a variable. See the examples in the GWT docs.
I don't address modifying the source document in this post.
To send the result, simply use the modified .parse() result:
RequestBuilder rb = new RequestBuilder(RequestBuilder.POST,
URL.encode(theHost));
rb.setRequestData(docQuestionnaire.toString());
rb.setHeader("Content-Length",
String.valueOf(docQuestionnaire.toString().length()));
Again, you will have more machinery around the above code.

Re: Query : Synchronous calls in GWT
Synchronous calls could make sense when one builds a standalone
application with a browser. Synchronous calls in such use cases could
be a useful tool. For example, pre-AJAX database lookups had to
preserve state in addition to returning query results. The resulting
calls either had to fail or complete in a finite time determined
entirely by the browser environment, not user code. Either way, the
application stopped while the query was in flight. In my experience,
such code is quite difficult to maintain.
Your application design may be such that data entry in conjunction
with an in-flight database lookup doesn't make sense. Nevertheless,
it's entirely possible that the reliability and maintainability of
your application will improve by designing it using asynchronous
techniques.
The "A" in AJAX is there for a reason. There's not much point in
trying to design around it.
There are other constraints, which are designed to handle the halting
problem (?), to such synchronous remote calls as you request.

Re: GWT vs GWT-Ext
I would recommend steering away from GWT-Ext. After working with GWT and GWT-ext for the past 6 months, my reactions are mixed. GWT-Ext does provide some very useful gadgets out of the box, but it is buggy, and I found it hard to work with. In addition, it does not seem to mesh well with the base GWT objects. Unfortunately, there is not much else out there. I have developed my own customer widgets to serve my own purposes, and used GWT-ext only when needed. Another GWT widget library I found useful was: http://gwt-widget.sourceforge.net/ - Bryan On Aug 27, 2:18 pm, "Dru Devore" <[EMAIL PROTECTED]> wrote: > Is there something else you are using instead of the ext stuff?

GWT-Ext is a very pretty toolkit. That licence change is an impact that hits me during my decission phase (which GUI i should use for my projects). We dont want to start to write our own widgets.

It sounds like the box isn't getting focus. You might want to attach
a FocusListener to monitor that. You could also try tabbing to the
box and see if that makes a difference. Also, do you have any

Hi, GWT is the official toolkit released by Google. It provides the java->javascript compiler and some basics widget. GWT-Ext is a wrapper around the Extjs javascript library, that use the GWT compiler. It provide similar widget to GWT and some others that don't exist in GWT. I personnaly stop using GWT-Ext because it's supported by a few developpers (so it takes time to fix bugs), and due to Extjs licence change, I'm not sure it will continue to be supported.

Re: Getting the generated RPC POST payload in the client
Julien, By "large RPC call" do you mean that you would like to post a large body of data to the server? Sniffing around your question a bit, it seems like you may not be aware of GWT-RPC, because sending arbitrary amounts of data to the server using that involves no programming gymnastics at all. Can you clarify a bit where you are and how you got there?

Re: How to make an Emd to End application in GWT ?
You can have more than one entry point in an application and it will make no appreciable difference to the compile time, caching, compression, reuse or deployment time Same goes for splitting your application into different modules. What *will* make a difference is if you produce different versions of the application for different situations Ian 2008/8/27 jhulford <[EMAIL PROTECTED]> > > On Aug 27, 7:49 am, walden <[EMAIL PROTECTED]> wrote: > > Sam, > > > > It's possible (and documented in the archives of this list somewhere) > > to use a single EntryPoint to instrument multiple HTML pages with > > GWT.

Re: How can i work with 2 Window
In the help window, you call a JSNI method to set up a functuin which
calls the GWT method in the ordinary JSNI way ('@' -signs <'@'%20-signs> and
'Ljava/lang/String' and all the rest), then in the owner of the help window
just use helpwindow.myMethod(parm1, parm2,...)
I've just tried it (after a bit of faffing about) and my popup blocker
didn't block it (since I clicked a button, I suppose) but it does open up in
another tab, which probably isn't what you want. And if you open a new
window, then working in the original window means the help window gets
covered. Unless the two don't overlap (but in that case, you have room to
resize the window for a dialogbox or splitpanel)

GWT vs GWT-Ext
Hi, I'm a new to this platform. While browsing on net I could see GWT and GWT-Ext. Is each a standalone development environment? Is GWT needs to installed before using GWT-Ext?

problem with keyboard listener on textbox
I'm trying to create a widget that will always enter the current time
whenever the user types 't'. My problem is that the keyboard listener
does not fire the first time the user clicks on the textbox with the
mouse, and then presses a keyboard button. If the textbox is clicked
on a second time, the listener will fire when the user presses
keyboard keys
Below is some sample code that I'm trying. Any help would be greatly
appreciated.
public class Testbox extends TextBox {
public Testbox() {
this.addKeyboardListener(
new KeyboardListenerAdapter(){
public void onKeyDown(Widget sender, char keyCode, int modifiers)
{
GWT.log("pressing a key in testbox", null);
}
}
);}}

Getting the generated RPC POST payload in the client
Hi all, My company started using GWT for a project a few weeks ago and I must say we all enjoy working with it. I am currently running into a small problem and thought some of you guys may be able to give me a few advices. I would like to perform a large RPC call using a nested IFRAME. In order to do that, I'm trying to encode the call as a GET request (by passing the payload as a parameter) so that I can modify the URL of the IFRAME. I've successfully modified my servlet to decode the call, but I have trouble modifying the client. I know that I won't be able to get the nice "method call" syntax, but I was hoping to be able to reuse parts of the serialization logic. Given a proxy for the remote service, the name of the method and a list of parameter types and values, is there a way to generate a string containing the payload? I tried to use createStreamWriter() of RemoteServiceProxy but the returned writer doesn't seem to encode the payload with the same data as usual calls.

HistoryListener Delay in IE
I am noticing some strange behavior in IE7 with the HistoryListener. It seems that when I click on a hyperlink in my application using IE, there is always a 2-3 second delay before the onHistoryChanged method is actually called. I have tested this with Window.alerts() in the beginning of the onHistoryChanged method, and it is consistent across all my pages. When I test my application in Mozilla (2.1 & 3.0), there is no lag, and the onHistoryChanged method is immediately called (making a very more responsive application). I have been developing an application with GWT for the past 5 months, so the Javascript is quite large (~1.1 MB OBF). I have many modules (30-40), and for now, I have them included all under one entry point. I could break them out into 3 entry points, but I wanted to get some feedback on what might be the possible problem. Is having one entry point (and thus a large JS file) the culprit in IE? Or is it just a browser problem? From what I understand, events bubble up in IE, and thus there could be a delay before the onHistoryChanged handles the event. Has anyone else noticed similar behavior? It just seems annoying because it makes the application seem very unresponsive in IE. Whatever feedback would be appreciated.

Re: Query : Synchronous calls in GWT
GWT is a powerful framework, and it is certainly possible to create a
Synchronous XHR with it, but it is such an epically bad idea that 1)
it is not available by default, 2) everyone who is familiar with GWT
development is warning you against doing it, and 3) we sure aren't
going to go through the effort to write the code to do it for you.
As for the code clarity, argument, my async code is quite clear and
maintainable. The request type really has nothing to do with how clear
or readable your code is.
That said, if you really want to create synchronous requests then
you'll need to look at the request builder code to see how the Async
requests are done, then do a google search on javascript
XMLHTTPRequest and see how to make the request synchronous. then
extend request builder (or create a parallel class) to do that.
But remember this is the programming equivalent of designing a wall
heater with the express design decision to start the consumers house
on fire. It really is that bad!

Re: How can i work with 2 Window
As long as the new browser window was initiated by your app, there shouldn't
be a problem communicating between the two.
You'd have to write your own JSNI functions to control it, but it's quite
possible.
Window.open("help.htm", "helpwindow",
"location=0,status=0,scrollbars=1,width=150,height=200");
Then in JSNI just refer to it as 'helpwindow', as in
helpwindow.moveTo(0,0);
The only problem you'll hit is that most people will have popup blockers
which will stop it showing, whereas the minimisable dialogbox will always be
allowed or course.

Re: Query : Synchronous calls in GWT
al0, No, actually it's not a workaround. Its an even better user experience, because if the controls on the page still look like they are active (but they're not because the browser is locked up), then the app is lying to the user, whereas if the controls are explicitly inactive, then we're telling the truth. Your point about code clarity is valid. But consider this tradeoff: Option A: your code is clear, but your user is confused and frustrated trying to use your site Option B: your code is spaghetti, but your user is delighted and keeps coming back Sure, these are extremes, chosen to make the point, but which do you choose?

You're not going to get the full benefit of caching / compression / re- use by doing that though. Each different entry point / module will result in a separate set of javascript files. There's definitely a trade-off in that 1 separate module per page is easier to maintain, but using 1 monolithic module will more than likely get you a better user experience. You'll also increase your deployment compile times quite a bit doing many different entry points. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Query : Synchronous calls in GWT
ping2ravi,
It's true that good and poor are relative terms, and it's also true
that design can be viewed as a matter of selecting among tradeoffs.
The reason you (and others) receive so much flack on this list for
stubbornly insisting on a synchronous RPC mechanism is that it trades
off user experience so horribly that it couldn't ever possibly be the
right thing. Whether or not you buy into that worldview, please
realize that it is the position of the GWT founders (specifically:
user experience comes first), and is unlikely to change.

Re: Could not find a native method with the signature fireOnModuleLoadStart
Hi I created a GWT project from one computer, and it was tested OK with hosted mode. Then, I simply copied the entire GWT project folder to another computer and this will cause the same exception.

Apparent content size inflation with GWT RPC - the cure?
Recently, I was researching a way to get rid of an XML document we use in our Web based app for state communication. The hope was that JSON/GWT RPC would crush out all the tag and attribute noise we had in the document. For smaller sets of data, this seemed to be true, though the savings was only 30% reduction and the time cost on the client side kind of made that iffy.. it was smaller. However, when I ramped up the testing from a 3K XML document to a 34K one... ouch. The content-length of the posted data inflated to 54K? Basically I have a simple set of DTOs, one is an xml node that has name and text fields, an array or 0 or more node children, and a reference to attributes. Our XML follows a pattern and this pattern seemed most simply captured in this structure. Now, I have tried hashtables for the attributes and the size seemed to be a little more for that. I also tried a List for the child nodes.. no improvement. (FYI - Of course, I did the gwt.argType annotations). The HEX dump using Fiddler shows a lot of encoding, the content header seems to indicate utf-8 encoding. Now, I know in some cases UTF-8 can inflate string length (if I recall for non-ASCII chars). however, this is all ASCII in this test. A co-worker looked at the hex stream and suggested some binary data is being encoded using Base64. Hmmm? What binary data? All the content of my DTOs is String or it is null. Is there some explanation of this phenomena I can read? My searches so far turn up nothing. It just seems counter intuitive that a chatty XML file is more efficient than a lean JSON DTO. - John --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How can i work with 2 Window
My case is :
I have a page that have a textbox and a button. This button will open
another window that have many options for the content of the textbox,
like a list of picture to be selected. I can't solve this problem,
putting a combobox. I still need to put another window. if a click in
the picture, this action will set the text of textbox ( from the first
page ) to the path of the picture.

Re: Text Area autosize
Positioning things in a textarea is at least close to impossible...
thats why I started my project http://code.google.com/p/axedarea/
first place, it is useable to a certain degree, but you yet won't find
you being truely happy with it, as especially on the WYSIWYG quite
some front stuff is missing. As pure Texteditor with a lot of
additional awareness (like size, where each line/letter is positioned,
copy/paste events, keyboard events) it works already quite nice... And
AFAIK it has currently the best online VIM emulation avialable.

Re: VerticalSplitPanel setSplitPosition fails
@gregor If you have two (GWT) pages and page A has a tabpanel and the tabpanel has a splitpanel, then if the splitpanel is not showing and you go to the other page and back, then click the splitpanel tab, it will have gone awry again. It also assumes that the tabpanel is aware that the tab contains a splitpanel. If the splitpanel is created on the fly depending on the situation of the user/data/time-of-day/whatever and if the tabpanel might get hidden, and/or if a disclosure panel is involved, then it all gets rather complicated @loott I don't think adding it to the rootpanel will be easy since you will have problems trying to line it up/resize it with a window resize and so on. I'm sure the GWT team didn't intentionally design it this way. They are very focused on functionality and cross-browser support but seem to have a bit of a blind-spot (maybe lack of resources for testing) when it comes to how things might be used (or even how things *are* being used). I expect they will fix it eventually - how fast is anyone's guess. There are some seemingly simple fixes that fix problems which are obviously wrong which have been around for ages. Others get sorted almost immediately. Their priorities are different to ours. Well, it's their product... Gregor's workaround should be OK if you aren't going to swap the tabpanel (or a parent) out of the DOM and back again.

Re: How to make an Emd to End application in GWT ?
Sam, It's possible (and documented in the archives of this list somewhere) to use a single EntryPoint to instrument multiple HTML pages with GWT. The mechanism is to have the EntryPoint code discover which HTML document it is running in, and then switch on that. But that's probably premature optimization in your case, and I would avoid it for now. Simpler to create an EntryPoint/Module for each page you currently have, and use Module inheritance to reuse code. Keeping your current page structure is antithetical to using "DOM manipulation"; you do one or the other or some mix of each, but it's an architecture decision to subsume what are now two HTML pages into a single HTML page with richer DOM control. As Len says, you are looking down a path now where it will be key to discover pages that should be combined like that. Call it Document Refactoring: moving the boundaries of pages for a richer web experience in an evolutionary way. Get Martin Fowler involved; co-author a best-seller :-).

EnumMap and RPC serialization
Hi everyone
I'm using GWT 1.5.1, I have:
public enum EnumAppState implements Serializable {
currentModule,
currentWindow
}
public class AppStateContainer implements Serializable {
private HashMap map;
public AppStateContainer() {
map=new HashMap();
}
/* other methods */
}
and class AppStateContainer goes throught RPC serialization fine, but
when i change HashMap to EnumMap like this:
public class AppStateContainer implements Serializable {
private EnumMap map; /* causes compilation
ERROR*/
public AppStateContainer() {
map=new EnumMap(EnumAppState.class);
}
/* other methods */
}
GWT give mi compilation error: "[ERROR] Type '(..).AppStateContainer'
was not serializable and has no concrete serializable subtypes"
EnumMap is emulated by GWT, why serialization won't work? Are any
performance differences in implementation between EnumMap and HashMap
in GWT emulation?

Re: Query : Synchronous calls in GWT
Hi group, First of all, Ian, when I sent your wife for beer 7 years ago, she returned immediately with the cold ones. I'm not sure what happened in your case, maybe something in your environment [you?] that accounts for the different result. It occurs to me [being serious now] that when newbs ask about synchronous calls in GWT, what they really want to know is how to create a localized synchronous experience, not how to lock up all browser resources. A localized synchronous experience is simply one where all of the controls in the immediate UI are disabled, where "immediate UI" is subject to definition on a case-by-case basis. I could be just one sub-panel in the UI, or the entire tab, etc. Nevertheless, the *intent* is to communicate to the user "not ready". I think we've all erred on the side of thread theoretics too much in answering this question when it comes up. The recent mention of glass panels and otherwise disabled UI controls is a step in the right direction.

Re: Query : Synchronous calls in GWT
Ravi,
You can't give developers all options to design their own way. JavaScript
doesn't do all options, therefore you can't have all options in GWT.
The only thing a synchronous call does which an async call doesn't, is to
lock up the user's browser - all tabs, not just yours.
This is, relatively speaking, bad, when compared to allowing the user to
continue to use his/her computer while your application goes and does
something. And it may be a generalisation, but nevertheless, I think it's
true to say that bad things are not good.
Say I have two tabs, your app and Google search. Can you give me one (just
one) instance where you need (let alone have the right) to stop me using
Google search while your application is off doing something?
And how would you stop me if I had two browser windows open?
Synchronous calls are bad relative to the alternative.

Re: do somebody know how to access private field and method in gwt widget using jsni from custom class ?
Just access it. In JSNI, 'final', and 'private' do not exist.
You'll need to read up on JSNI. Here's an example:
public static native callGetSplitElement(HorizontalSplitPanel panel) /
*-{
[EMAIL PROTECTED]::getSplitElement()
();
}-*/;
Note the double ()(). The first () is part of the getSplitElement
signature (namely, the parameter list). The second () is the actual
parameters. In this case, getSplitElement has no parameters, so it's
just ()().
Also, you're still using private parts of an API. If you use these
tricks, your code is most likely not going to work with the next
version of GWT. Even a small point release might change things around.
You've been warned!

Re: Sending a variable between embeded HTML and GWT?
I have the same problem and I thought of using JSNI to fix it, but I
didn't try it until now.
You have to write a JSNI-Method, which defines a JavaScript-Method
that calls the Java-Code you want.
Something like that:
public native void initJavaScriptCall() /*-{
$wnd.callJava = function() {
[EMAIL PROTECTED]::functionToCall()();
}
}-*/
public void functionToCall() {
//TODO...
}
and then call the JavaScript-Function with the Hyperlink:
Link
Hope this works! Jakob

application are nothing but hyperlinks with background image.
when you select the link(or tab) it shows selected image as
background. Otherwise it shows unselected image as background.
my code is:-
hLink_.setStyleName("evpn-tabbedButton");
and css is:--
.evpn-tabbedButton a:link
{
font-size: 12px;
font-family: Arial;
color: #ff;
text-align: center;
white-space: nowrap;
background: no-repeat center top url ('/
com.infovista.vistamart.evpn.Home/resources/images/
tab_unselected.gif');
width: 79px;
height: 17px;
}
.evpn-tabbedButton a:active
{
font-size: 12px;
font-family: Arial;
color: #ff;
text-align: center;
white-space: nowrap;
background: no-repeat center top url('/
com.infovista.vistamart.evpn.Home/resources/images/tab_selected.gif');
width: 79px;
height: 17px;
}
But in my application, tabs are working completely like links
(not like tabbed buttons). If I select a tab(menas hyperlink) then it
is appearing like selected tab(means background is selected image).
but if i click any where on the browser then the selected tab(link) is
appearing as if it is not selected(because background image is
changing to unselected image).
How can i implement the code in such a way that hyperlinks should work
as tabs with selected. unselected, and hover style sheets.

Re: VerticalSplitPanel setSplitPosition fails
Hi Loott, You should be able to get the split panel to position it's splitter when its tab opens using a TabListener and calling sp.setSplitPosition(..) from onTabSelected(). You only need to do this once, I believe. After that the split panel will remember its splitter position and re-open properly. Clunky because you'd have too keep some boolean variable to indicate the SP has been opened, but I think it would work. If I'm wrong and it doesn't remember, then you could save the percent split position value and use it for repeated calls from onTabSelected(..). I had a look at the source for the split panels the other day when Ian posted about this, and as I recall the root of the problem is that HSP/ VSP have a onLoad() method that issues a DeferredCommand to size the left and right containers and set the split position. If the Sp is not visible it has no height or width to work with, so split position is always zero. I can't find an issue raised for this on the issue tracker, although I think it is briefly mentioned on issue 1599 http://code.google.com/p/google-web-toolkit/issues/detail?id=1599&q=split%20panel regards gregor On Aug 27, 9:02 am, loott <[EMAIL PROTECTED]> wrote: > Hello Ian, > > thank you for your answer.

Re: Query : Synchronous calls in GWT
Jason,
I think any framework should give all options to developer to design
his own way, and poor design and good design are all relative terms,
so cant do generalization of that.
But thanks for sharing your thoughts.
cheers,
Ravi :)

Re: How we can stop control until we receive complete response from GWT
He Feroz, Just another idea to stop-and-wait which I use: I use events everywhere across my app to control what should happen, like app-init, start-..., etc.. The events are catched by pieces of code that can indicate in the received event, that it must wait further dispatching any event (= stopping the app). When the response is received, I inform the event that it can continue, such that the central dispatcher will start dispatching all events that it had received after the wait request. I use this mainly during startup to load some CMS files. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: How can i work with 2 Window
Interesting discussion, something I still have to solve as well. In my case (not exactly the same as the starter of this discussion) I have a GWT help window (looks like the MS help) that I want to control from within my main GWT application. That is: if someone clicks the help button next to some item on the main GWT application (window) I want to open (if it wasn't open already) the help GWT app in a separate window and control the information it shows. The help window doesn't need to know anything about the main app, except that it would be nice if it can report that it was closed. I would like the help to be in a separate window such that the user can put it anywhere he wants. How is it possible to control the help GWT app (controlling the information that is shown) from within my main GWT app (that contain the help "pointers")? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: VerticalSplitPanel setSplitPosition fails
Hello Ian, thank you for your answer. It's disapointing to know i can't add a SplitPanel inside a TabPanel :( as it's a very common user interface case. I suppose i will have to add the splitpanel to RootPanel for example and make it visible or invisible when the tab is clicked or use the deferred commands as you say or something like that... It's not a good solution concerning the design of the application, do you know any other cleaner solution? Do you know if there's a interest in GWT to allow this or is it assumed that this should be the behaviour of SplitPanels?
