I'm only just starting to dive into GWT internals but I believe to do
this you will need to create a Parser for your widget to be recognized
internally by UiBinder.

http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/uibinder/elementparsers/TabLayoutPanelParser.java

The method error your getting is from the fact that GWT is magically
trying to map the attribute which it has failed to deal with in any
meaningful way to a method in your class which of course doesn't
exist. You'll notice within that parser that barHeight and barUnit are
being consumed by the parser.

And of course the rest of the parser is about dealing with the child
tags that it supports as special.

Given the absence of a vertical TabLayoutPanel in GWT, I was trying to
patch the TabLayoutPanel code in my local space by copying the
TabLayoutPanel source code and modifying it. However, when I use
UiBinder to construct my UI, I run into a problem that makes me wonder
how UiBinder works behind the scene.

First I have my locally modified TabLayoutPanel class, which I name it
MyTabLayoutPanel.
Then I use it in a UiBinder template like this:
...
g:MyTabLayoutPanel barUnit='PX' barHeight='35'
g:tab
g:header size='7'ABC/g:header
g:LabelThis is a test/g:Label
/g:tab
...
/g:MyTabLayoutPanel

When running the program, I ran into the following issues:
- Class MyTabLayoutPanel has no appropriate setBarUnit method...
- tab not found, obviously UiBinder doesn't recognize the g:tab
thing

If I switch MyTabLayoutPanel back to the standard TabLayoutPanel,
everything works. In fact, to trouble-shoot my problem, I merely copy
the original GWT TabLayoutPanel to my app code space and rename it
MyTabLayoutPanel without any other modification.

When I look at TabLayoutPanel code, I notice the constructor takes a
barUnit and a barHeight as arguments. I wonder why widgets in
GWT's own SDK do not need to follow the rule of providing an empty
constructor or using things like @UiConstructor. Also, if I want to
natively write my own widget to support things like g:tab,
g:cell etc in UiBinder, how should I do it?

Any advices would be highly appreciated.

Re: Does a private variable in Java stays private when compiled to javascript?

2010-06-22 Thread Shedokan

I want to allow people to add javascript extensions to my app using an
API I'll make with GWT, so I don't want them to be able to be able to
access private variables my app uses.
The problem is that GWT does symbol obfuscation so there is no way to
have a list of unallowed variables.

There is a GWT module you can include that might make life a bit

and how it works.

Hi again,

So, your list responds to clicks...

Re: MVP Framework in GWT 2.1 M1 ?

The one half of Expenses isnt even MVP. The one you access via
Expenses.html is a hard-wired app. That is the one they were showing
at Google I/O.

The other part, the Scaffold app I believe is what Roo spits out found
under Scaffold.html. I'm not sure as to just how much of that has been
hand tweaked and how much is straight up codegen. Of course, all of
that stuff is still under heavy development.

I'm certainly not the best developer/architect going round, but I like

This expenses example is a nightmare to follow. The bindings/wiring

I sure hope Spring Roo can generate an excellent CRUD starter
application for me based off my domain objects and their
relationships, cause there is no way in the world I could have come up

Re: Million access to GWT Appl ??

Your essentially asking the wrong question. I think its better to
think of by how much will GWT or products similar to GWT reduce the
load on a server.

You have to consider the fact that every user accessing a traditional
website backed by a templating engine involves alot of resources for
each and every request for new information.

Take a web forum for example. I think they are probably one of the
least effecient communication mediums and would be very interesting to
see a GWT implementation of one. With the status quo web forum you
have full page loads happening every single time a user wants to move
around on the forum. And if the user wants to see what is new on the
forum... you guessed it, full page load.

Now, if you consider all the ways that having most of the web forum on
the client side and using much more lightweight RPC calls to get new
info (and ONLY new info) there would be quite large improvements. I
wouldnt be suprised if the resource requirement of a GWT based web
forum dropped the load on even the most highly active forums by
upwards of 80%, and probably more if you really took the care to setup
some proper caching. But regardless of how the server resource load
would drop, just the bandwidth drop alone would be a 100% win.

Re: Theory behind UiBinder that makes TabLayoutPanel work

Re: Dynamic Module Loading

If your need is only to define new view (with few logic), maybe using
a descriptive language will be better. You can write a templating
engine using GWT like a XUL interpreter or something like that. This
is not the best approach for optimized JS (file size, speed...) but
may be the best compromise. I think GWT compilation is too heavy to be
done on server, and worse, on the fly.

Re: Dynamic Module Loading

2010-06-22 Thread rudolf michael

Well this is similar to the Generator/Factory concepts.

They don't want to go with this approach although i was able to load the
Factory/Generator class from the server and use it in the client code to
generate my UIs from the definitions POJOs.

Since they have a flash background, they want to load an INSTANCE of a UI
View from the server and plug it in its appropriate location. I have already
told them that my UIObjects are not serializable and i cannot get them from
the server but then this might be feasible with native js and static html.

I am having hard time to convince them that the Generators are not bad.

Why appear OPTIONS instead of POST in my RPC calls?

2010-06-22 Thread enTropy Fragment

Hello

Here is my problem:
When I call my rpc from inside the war everything works well, but when I
call the same rpc calls from the same GWT javascript client stuff but
injected into an external web site the rpc makes the call with HTTP OPTIONS
instead of HTTP POST method.
I'm very interested in calling the rpc this way...

How can I make this work?

Not the parent object. Your class is erp.client.Test but the class
of u is erp.client.Test$1. $1 means the first anonymous class of
Test. This is a Java behavior.

Re: Dynamic Module Loading

I don't know the full story, but maybe the problem is not a technical
one. You can't change technology (Flash = GWT) without doing some
change in your architecture... If they don't want to explore new way,
they must keep their technology.

incubator SCrollTable scroll position.

2010-06-22 Thread Subhrajyoti Moitra

Hello Folks,

I am using incubator gen2 ScrollTable. I have a use case, wherein i have to
detect that when the user has scrolled to the last row (or somewhere around
the last row), then load a fresh set of rows in the table, via a rpc call.
TO achieve this i have extented ScrollTable and implemented
HasScrollHandlers.

public class UbqScrollTable extends ScrollTable implements HasScrollHandlers
{

public UbqScrollTable(FixedWidthGrid dataTable,
FixedWidthFlexTable headerTable) {
super(dataTable, headerTable);

}

public HandlerRegistration addScrollHandler(ScrollHandler handler) {

return addDomHandler(handler, ScrollEvent.getType());
}

}

And later in some other view i am setting up this table, and the initial
data to go along with it.
When trying to get the scroll position, i do this. st is the scrolltable.

st.addScrollHandler(new ScrollHandler() {

public void onScroll(ScrollEvent event) {
int top=event.getRelativeElement().getScrollTop();
int
scrollHeight=event.getRelativeElement().getScrollHeight();
int left=event.getRelativeElement().getScrollLeft();
int width=event.getRelativeElement().getScrollWidth();

GWT.log(Scroll data: top: +top+, scrollHeight:
+scrollHeight+, y: +event.getNativeEvent().getScreenY()+, x:
+event.getNativeEvent().getScreenX()+, left: +left+, wiodth: +width+,
class: +event.getSource().getClass().getName());
GWT.log(Top:
+st.getDataTable().getElement().getScrollTop());
GWT.log(Height:
+st.getDataTable().getElement().getScrollHeight());
//st.getElement().setScrollTop(50);
}
});

All the values top, height, left, width are all constant and not changing. I
know there is something wrong with my understanding. Please help.

How do i get the scroll position, or Detect that the user is viewing the
last few rows of the scroll table so load new rows from backend?

Please help.

Thanks,
Subhro.

 Use a @uihandler annoration in the java class to

Re: Implementing login and maintaining sessions

Thanks for the response... A few questions come up:

1. I'm using an HttpServlet for authentication, along with
RemoteServiceServlets for GWT-RPCs. But if I create an HttpSession in
my authentication servlet, I cannot seem to access it on the
RemoteServiceServlet... How am I supposed to access it? Example:

// In authentication HttpServlet
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
  // ...
  req.getSession().setAttribute(user, new User(testUser)); //
creates a session if it didn't exist beforehand
  // ...
}

// In GWT RPC servlet
public ListOffer getOffers(int productId) {
  // ...
  User user  = (User)
getThreadLocalRequest().getSession().getAttribute(user); // returns
null
  // ...
}


2. Why are you using a MainSession singleton object? I don't see it...
Wouldn't it also fail once you have multiple users logged in at the
same time?

3. In your Main page, you're doing 2 sequential RPC calls before you
render anything: one to check logged in status, and one to load page
contents. Is this advisable or could it be avoided somehow? For
example, the server could set up a cookie with 'loggedIn=true' so that
you can skip the first RPC at least. And whenever you actually have to
fetch private content, the server can fail with a
AuthenticationException if the user is in fact not logged in. So if a
malicious user fakes the cookie to say he's logged in, the most he'll
ever see is a 'Logout' button when there shouldn't be one. Any other
place that needs to show user-specific information would still be
protected at the server. Does this make sense? What are the drawbacks
of this?

4. I assume the SessionTimeoutControl() object just sends an RPC to
the server every x seconds to check if the session is still alive or
not, correct? How do HttpSessions work across tabs and browsers? If my
user has 2 tabs open at my site, does he have 1 or 2 sessions? If it's
2 browsers?

Thanks!

         Person person = null;

         try {
             ManageLogs.info(Try to login for user: +username);

Re: Implementing login and maintaining sessions

Ok I just answered 1.5 of my questions:

#1- It actually does work, using getThreadLocalRequest().getSession().
My test had failed for an alternate reason.
#4- (second half) Sessions are per-browser, so multiple tabs in the
same browser share sessions, but cross-browser tabs do not.

The other questions remain...

 2. Why are you using a MainSession singleton object? I don't see it...
 Wouldn't it also fail once you have multiple users logged in at the
 same time?

 3. In your Main page, you're doing 2 sequential RPC calls before you
 render anything: one to check logged in status, and one to load page
 contents. Is this advisable or could it be avoided somehow? For
 example, the server could set up a cookie with 'loggedIn=true' so that
 you can skip the first RPC at least. And whenever you actually have to
 fetch private content, the server can fail with a
 AuthenticationException if the user is in fact not logged in. So if a
 malicious user fakes the cookie to say he's logged in, the most he'll
 ever see is a 'Logout' button when there shouldn't be one. Any other
 place that needs to show user-specific information would still be
 protected at the server. Does this make sense? What are the drawbacks
 of this?

 4. I assume the SessionTimeoutControl() object just sends an RPC to
 the server every x seconds to check if the session is still alive or
 not, correct? How do HttpSessions work across tabs and browsers? If my
 user has 2 tabs open at my site, does he have 1 or 2 sessions? If it's
 2 browsers?

Re: UIBinder Benefits?

2010-06-22 Thread Andrew Hughes

Almost all of the problem's listed below are bad advice and I suggest you
disregard them. Except for the it's a graphic designer mindset - this
statement is correct. Thankfully we no longer need to code our layout and
style in java!

The main problem I have with UiBinder is that when you try and use it with
the MVP architecture best practice, you have to boilerplate all the
parent/child (view) widget's. Which means you'll see a lot of.

@UiField(provided=true)

You then need to programatically decide/code when the uibinder should be
called.

I would still recommend it.

On Mon, Jun 21, 2010 at 11:47 PM, Stefan Bachert stefanbach...@yahoo.dewrote:

Hi,

I don't use UiBinder in general. It may be nice for some hacks.

UiBinder has a lot of problems
* a further language. No way to debug it

* limited to a set of widgets
* it is a graphic designer mindset (we do this app, the app is our
concern) not a developer mindset (we do this class of apps, we
separate concerns)
* no clear separation, no SoC. A big bunch of widgets and css-styles.
* no separation of theme/skin

When you watch the video with Ray Rian (gwt wave, discussion) you
clearly read between the lines that he doesn't like UiBinder, too.

The only advantage I see, it is faster to create a fragment of HTML
code than to build it via java/javascript code. But how often you will
create a html-structure? In a good design this will rarely happen.
And performance is one but the only design goal.

Re: Error: Permission denied for domain2 to get property Location.href from domain1.

Actually since my application has multiple segments, I cannot use
cross site linker.

PageA really has nothing to do with the script, but it seems GWT
hosted.html tries to get Location.href from the parent window rather
than the iFrame.

Re: Million access to GWT Appl ??

2010-06-22 Thread Stefan Bachert

Hi manish,

the opposite is true.

An AJAX/GWT-approach reduces dramatically the load from the servers.
I showed in an estimation that with GWT/AJAX a server is able to drive
10-50 times more clients, compared to classical web technology like
JSP, JSF
So using GWT is also a green IT topic.

The german reading audience may look at
http://gwtworld.de/bin/Offen/Strom%20sparen%20mit%20GWT

Till now I do not see any technology which is using energy and
performance more efficient and responsible than GWT.

I dont know exactly how many users are using Google wave. Google wave
is a GWT application, it is fast, and I guess it has millions of
users.

When you are really going to develop an applications for millions of
users, you urgently should use GWT.

Re: Implementing login and maintaining sessions

Not sure if I understood your question.. But yes, the cookie is
accessed both at the client and at the server. So the server would set
it to 'loggedIn=true' upon a successful login, and clear it whenever
the user logs out OR if the server gets a request for private
information but the Session indicates that the user is not logged in..
In that case, it clears the cookie and fails with an
AuthenticationException. The client redirects the user to login
whenever an AuthenticationException is received.

Thus, the usage of the cookie allows the client to save some RPC calls
to the server. If a page doesn't contain private user-specific
content, but should still look different based on whether the user is
logged in or not, then the client can go off the cookie's information
and decide whether to display a 'Login' or 'Logout' button, for
example.

Re: Error: Permission denied for domain2 to get property Location.href from domain1.

It shouldn't violated SOP since PageA really has nothing to do with
PageB.

PageA just displays PageB in an iframe.  PageB scipts should do their
work in the context of host page B.  and I have no intention to
violate SOP.  But I don't know GWT bootstrap well enough to understand
what hosted.html gwtOnLoad function is doing that causes the
violation?  Feels like a bug.

Did I misunderstand SOP?

Ok I confirmed it's not SOP violation in my design.  The script runs
fine in web mode.  It's only considered a violation in host/
development mode.

I am not sure how to configure the DevMode to get around the
violation.  Any thoughts would be appreciated.

Re: Error: Permission denied for domain2 to get property Location.href from domain1.

2010-06-22 Thread Jeff

Actually, if i'm not wrong, the JavaScript that your client recieves
comes from page B, on domain 2.

Well, you got this error :

Permission denied for Domain2 to get property Location.href
from Domain1.

It looks like you're trying to use something situated on domain 1
(Location.href) from domain 2. This is very likely to be a SOP
violation. But i'm not considering me as an expert so if we could have
confirmation from someone more experimented... ^^

It's this line on hosted.html in GWT bootstrap process that causes SOP

is no violation in web mode?

Re: Implementing login and maintaining sessions

Hey,
I try your approach with cookies and seems to works fine!

Thanks :)

On Tue, Jun 22, 2010 at 3:07 PM, Rodrigo ipi...@gmail.com wrote:

 Not sure if I understood your question.. But yes, the cookie is
 accessed both at the client and at the server. So the server would set
 it to 'loggedIn=true' upon a successful login, and clear it whenever
 the user logs out OR if the server gets a request for private
 information but the Session indicates that the user is not logged in..
 In that case, it clears the cookie and fails with an
 AuthenticationException. The client redirects the user to login
 whenever an AuthenticationException is received.

 Thus, the usage of the cookie allows the client to save some RPC calls
 to the server. If a page doesn't contain private user-specific
 content, but should still look different based on whether the user is
 logged in or not, then the client can go off the cookie's information
 and decide whether to display a 'Login' or 'Logout' button, for
 example.

   RemoteServiceServlets for GWT-RPCs. But if I create an HttpSession in
   my authentication servlet, I cannot seem to access it on the
   RemoteServiceServlet... How am I supposed to access it? Example:
 
   // In authentication HttpServlet
   protected void doGet(HttpServletRequest req, HttpServletResponse resp)
   throws ServletException, IOException {
// ...
req.getSession().setAttribute(user, new User(testUser)); //

User user  = (User)
   getThreadLocalRequest().getSession().getAttribute(user); // returns
   null
// ...
   }
 
   2. Why are you using a MainSession singleton object? I don't see it...
   Wouldn't it also fail once you have multiple users logged in at the
   same time?
 
   It works fine for multiple users  because for each new request a new
 
  different session ID will be
  generated, and so a new session.
 
  3. In your Main page, you're doing 2 sequential RPC calls before you
 render anything: one to check logged in status, and one to load page
   contents. Is this advisable or could it be avoided somehow? For
   example, the server could set up a cookie with 'loggedIn=true' so that
   you can skip the first RPC at least. And whenever you actually have to
   fetch private content, the server can fail with a
   AuthenticationException if the user is in fact not logged in. So if a
   malicious user fakes the cookie to say he's logged in, the most he'll
   ever see is a 'Logout' button when there shouldn't be one. Any other
   place that needs to show user-specific information would still be
   protected at the server. Does this make sense? What are the drawbacks
   of this?
 
   I need those 2 because I can olny load the content if the
 authentication
 
  was successful,
  and when that happens on the server side, the http session is created and
  also the user
  information is loaded.
  An only after this is possible to load the content.
 
  With a cookie, then on the client side I need to access to that cookie...
  actually I didn't check that,
  but the access to the cookie is not done on the server side, also ?
 
   4. I assume the SessionTimeoutControl() object just sends an RPC to
   the server every x seconds to check if the session is still alive or
   not, correct? How do HttpSessions work across tabs and browsers? If my
   user has 2 tabs open at my site, does he have 1 or 2 sessions? If it's
   2 browsers?
 
   The session time out control actual do more than that it uses the gwt
 Timer
 
  to  initialize an schedule in a new thread
  for a defined period of time, and the alert the user when the session is
  about to expire,
  if there the user do any event it will send a keep alive and
  re-initialize
  the schedule, otherwise invalidate session
  e redirects to Login page.
 
  Across tabs will keep the same session until the user logout or the

  Across browsers a new session is nedded.

Re: Need to build a WYSIWYG XML editor

2010-06-22 Thread aliman

Hi, I'm not sure this answers your question, but GWT does have an XML
API, see [1].

FWIW I did do some work previously with GWT and XML, but the lack of a
createElementNS method was a real blocker. You can seach an XML
document in a namespace aware manner, because the Node interface has a
getNamespaceURI() method, but you cannot build an XML document with
namespaces, except by constructing the document as text, then calling
XMLParser.parse(). If you want to create a code editor, that may be a
valid workaround for you. I did write some convenience code to work
around this a while ago, see [2], however this is a bit of a hack, and
I've since moved away from GWT to using XForms and Orbeon [3] for that
particular project, because of the much better XML support.

Re: Modify Java source file at compile time, possible?

Kevin,

It depends one the which generator can know which interface.

If the generators can know both interfaces, you can create only one
generator. All code generator is pushed to sub classes like
IntrerfaceAWriter and InterfaceBWriter. The generator looks for
several interfaces from the marker interface and call the
corresponding writers.

If one generator (generatorB) can know the other interface (intefaceA)
but not the reverse, it can add a field like:

private InterfaceA wrapped = GWT.create(InterfaceA.class);

Then it implements all InterfaceA's methods and forward call to the
wrapped field.

If none of them can know the other interface (like generators from two
frameworks), you can create an InterfaceC that extends InterfaceA and
InterfaceB. You add a generator that proxy all call to some wrapped
field like in the previous case, but for the two interfaces.

Do you like it?

Hi Kevin,

You can rewrite your Foo class as:

}

Then, associate a generator for sub-types of MagicClass and use
GWT.create to instantiate a new Foo.

GWT.create(Foo.class);

So your generator will be called. It can generate a FooImpl class that
extends the Foo class and override the bar method as follow:

public class FooImpl extends Foo {
 public void bar() {
   Log.log(begin of bar);
   try {
     SecurityContext.checkAuthorized();
     super.bar();
   }
   finally {
     Log.log(end of bar);

}

Where Log.log print some logs and SecurityContext.checkAuthorized
throws an error is the user is not authorized. This could be funny and
not really hard to do.

some
 annotations, I want to have the ability of injecting code at compile
time.

 e.g., with the class below

 public class Foo {
   @Log
   public void bar() {
     @CheckPermission
     dosomething();
   }

 }

 At compile time, I want to have the ability to get the annotations
available
 on items, and inject code according to my application logic. So here,
  the
 compiler should see:
 public class Foo {
   public void bar() {
     log(begin);
     if (hasPermission()) {
       doSomething();
     } else {
       error();
     }
   }

 }

 with the extra code being injected. I'm wondering if anything in GWT
allows
 me to do that?

cursor while server processing

2010-06-22 Thread Iván Navarro

hi,
is there any way to change the cursor (doesn't matter its position on
screen or if it is over certain widget) during an operation in the
server side?

I've tried adding a cursor style to the main panel with addStyleName
method, but it doesn't work. I don't know if it is for the server call
(in other situations it works properly) or because I only change the
cursor for the main panel.

Thanks in advance!

Re: Safari 5 - (RangeError): Maximum call stack size exceeded

2010-06-22 Thread pash7ka

There is an Issue 4393 about this bug.

I've applyed dunhamsteve's patch and also in all binarySearch()
functions in Arrays.java and Collections.java changed:
-  final int mid = low + ((high - low)  1)
+  final int length = high - low;
+  final int half = length  1;
+  final int mid = low + half;

and just repacked gwt-user.jar replacing those files.
This worked for me.

Re: cursor while server processing

2010-06-22 Thread Andreas Horst

Try applying the style to a Widget the mouse cursor will certainly hover
above and that is not covered by other Widgets, for example a Button. Make
sure you place the cursor above that Widget.

I'm not sure if this will help, but in case the Style is properly changed on
that Widget it should also be changed on the RootPanel. In that case it may
simply be completely covered and MouseEvents are not propagated to the
RootPanel. I had a similar problem regarding MouseEventHandlers. Anyway I'm
not sure if browser side changes to the cursor icon are based on MouseEvents
so it really is just a suggestions. Give it a try though.

 On Tue, Jun 22, 2010 at 3:07 PM, Rodrigo ipi...@gmail.com wrote:

 Not sure if I understood your question.. But yes, the cookie is
 accessed both at the client and at the server. So the server would set
 it to 'loggedIn=true' upon a successful login, and clear it whenever
 the user logs out OR if the server gets a request for private
 information but the Session indicates that the user is not logged in..
 In that case, it clears the cookie and fails with an
 AuthenticationException. The client redirects the user to login
 whenever an AuthenticationException is received.

 Thus, the usage of the cookie allows the client to save some RPC calls
 to the server. If a page doesn't contain private user-specific
 content, but should still look different based on whether the user is
 logged in or not, then the client can go off the cookie's information
 and decide whether to display a 'Login' or 'Logout' button, for
 example.

   RemoteServiceServlets for GWT-RPCs. But if I create an HttpSession in
   my authentication servlet, I cannot seem to access it on the
   RemoteServiceServlet... How am I supposed to access it? Example:
 
   // In authentication HttpServlet
   protected void doGet(HttpServletRequest req, HttpServletResponse resp)
   throws ServletException, IOException {
// ...
req.getSession().setAttribute(user, new User(testUser)); //
   creates a session if it didn't exist beforehand

User user  = (User)

// ...
   }
 
   2. Why are you using a MainSession singleton object? I don't see it...
   Wouldn't it also fail once you have multiple users logged in at the
   same time?
 
   It works fine for multiple users  because for each new request a new
 
  different session ID will be
  generated, and so a new session.
 
  3. In your Main page, you're doing 2 sequential RPC calls before you
 render anything: one to check logged in status, and one to load page
   contents. Is this advisable or could it be avoided somehow? For
   example, the server could set up a cookie with 'loggedIn=true' so that
   you can skip the first RPC at least. And whenever you actually have to
   fetch private content, the server can fail with a
   AuthenticationException if the user is in fact not logged in. So if a
   malicious user fakes the cookie to say he's logged in, the most he'll
   ever see is a 'Logout' button when there shouldn't be one. Any other
   place that needs to show user-specific information would still be
   protected at the server. Does this make sense? What are the drawbacks
   of this?
 
   I need those 2 because I can olny load the content if the
 authentication
 
  was successful,
  and when that happens on the server side, the http session is created
 and
  also the user
  information is loaded.
  An only after this is possible to load the content.
 
  With a cookie, then on the client side I need to access to that
 cookie...
  actually I didn't check that,
  but the access to the cookie is not done on the server side, also ?
 
   4. I assume the SessionTimeoutControl() object just sends an RPC to
   the server every x seconds to check if the session is still alive or
   not, correct? How do HttpSessions work across tabs and browsers? If my
   user has 2 tabs open at my site, does he have 1 or 2 sessions? If it's
   2 browsers?
 
   The session time out control actual do more than that it uses the gwt
 Timer
 
  to  initialize an schedule in a new thread
  for a defined period of time, and the alert the user when the session is
  about to expire,
  if there the user do any event it will send a keep alive and

  Across tabs will keep the same session until the user logout or the

Re: JSNI reference in iframe

another iframe

The setup is like this:
domain1/page1 has an iframe that loads domain2/page2
domain2/page2 has the GWT module.

In other words DOM looks like:
domain/page1
iframe (domain/page2)
iframe (gwt)

The module has the JSNI code that is intended to register a function
in page2 so other none-gwt components (again in page2) can use,
something like

$wnd.myfunc = function() {...}

And in my HTML, I do

input type=button onclick=myfunc()/input



I know it feels like I am trying to some cross site stuff between
page1 and page2, but I am not.  Page1 is simply a wrapper for
displaying page2.  All GWT and JSNI codes are intended to use within
Page2 alone.  That's where I am having problem.  I think because GWT
itself is in iframe and $wnd is intended to get top window, it works
in most cases when the host page is in the top window and on the same
domain.  But my hostpage is an iframe and different domain.

Right now my workaround is to declare a new javascript object on
page2, like

var myfuncHelper = new Object();

then my JSNI looks like

$wnd.myfuncHelper.myfunc = function() {...}

and the onclick=myfuncHelper.myfunc()

That works.  I am wondering if there is better implementation though.

[gwt-contrib] Re: UiBinder. Code style for constant parsers.

2010-06-22 Thread Konstantin.Scheglov


 Pretty much everything we've done so far has been limited to automatically
 exposing the Java-level APIs in all their ugliness. The h/v alignment values
 are implemented somewhat manually, but for things like enums I really like
 the idea that they can be exposed completely automatically.

 On the other hand, it would be nice to have prettier names. Perhaps we could
 find some sort of convention for exposing prettier names for [pseudo-]enums.
 What about a shortName() method on the enum itself?

  Hm...
  Yes, I think that it is possible to create some generic parser for
enum-like constants.
  However because they are not real enums, following things come to
mind:

1. During registration in AttributeParsers we will need to pass list
of values;
2. To check for shortName() using reflection;
3. To test that each such constant parser instance works correctly, I
would write special ui.xml file.

  Also one more thing worries me. Do you think that it is OK to add
into GWT classes on this level information which is used only by some
presentation of GWT? I mean that parsing ui.xml files is part of
UiBinder, so it should be problem of UiBinder how to parse it.

I think we need a few more tests to be sure that sublists are working as
intended.  If things are problematic after adding more tests, another
approach that might help would be to move the fromIndex and toIndex
fields into AbstractList -- then fix every list operation to respect
those bounds rather than using 0 and array.length or whatever.  Then
sublist becomes trivial.

My concern is that since there is no overriden version of
remove(Object), the superclass version won't respect fromIndex and
toIndex, so it will remove the element from the base list even though it
is not part of the sublist.

It's possible that this works fine -- I haven't tried to examine all the
superclass code -- but in any case I would like to see it as part of the
test case.

OK, I see that the implementation uses iterators for these operations,
which will respect the list bounds.  So I'm not as concerned although
more tests would still be a good thing.

Does this mean that once a sublist view is defined, and the

I would

say yes, but would like to hear other comments as well. I tried this

on sun jdk

and once I modified the underlaying list and afterwords tried to

access and/or

modify the sublist view I got exceptions thrown.


Yes, it means if you modify the underlying list in a way that would
invalidate iterators on it (such as adding an element), the behavior of
the sublist is undefined.  That means it could work properly, it might
throw exceptions, or it might totally destroy the underlying data
structure.  In general, the Sun JRE detects such conditions and throws
exceptions, but we don't do so in our JRE - the overhead would be rather
large.

[gwt-contrib] Early feedback on PlaceController/ActivityManager

2010-06-22 Thread Thomas Broyer

Aside from not being plugged with the History (yet), the one thing
that bothers me (a little), something that I have in my current (very
own) PlaceManager that isn't in PlaceController/ActivityManager, and
contrary to History-binding has an impact on the API, is plumbing
between PlaceController and WindowClosingEvent.

As it is done now, a PlaceChangeRequestedEvent can be rejected,
which prevents a PlaceChangeEvent from being fired subsequently. At
the Activity level, the current activity can refuse to
stop (willStop() returns false).

I suppose the intended use that the PlaceChangeRequestedEvent handlers
(or the current Activity) eventually displays a Window.confirm(...) to
condition the call to reject() (or the return value of willStop()).
All is well, but what happens when the user closes the browser window/
tab?

In my PlaceManager, the PlaceChangingEvent is very similar to the
WindowClosingEvent, i.e. you can cancel the action, but you have to
give a message to be shown to the user. The Window.confirm(...) call
is done in a ConfirmationCallback given to the PlaceManager. What it
means is that on a WindowClosingEvent, a PlaceChangingEvent is fired.
If a handler wants to request cancellation, it sets a message on the
event. The message is then set on the WindowClosingEvent so that the
browser shows its own confirmation dialog, with the application-
provided message.
In other cases (i.e. not WindowClosingEvent, that can be a history-
driven or programmatic navigation), when a PlaceChangingEvent is
rejected, the message is passed to the ConfirmationCallback, which
returns a boolean, which conditions the firing of a PlaceChangeEvent.
(in my original design, the ConfirmationCallback could be asynchronous
to allow uses of a DialogBox for instance,  but it has all sorts of
implications –i.e. what happens when a WindowClosingEvent or history's
ValueChangeEvent is fired while confirming a previous navigation
request?– so I only implemented the synchronous confirmation, in the
form of a boolean confirm(String message) method on the
ConfirmationCallback interface).

My design supposes a PlaceChangingEvent's rejection is always
subject to a confirmation (by the user), which is maybe not the case
in the proposed GWT's PlaceChangeRequestedEvent.

Do not hesitate to ask for more information on my PlaceManager. Ray
(and other G-men; I put Ray in Cc as he's the only one of you who
committed on these classes), I have a still-draft detailed description
of my PlaceManager and particularly where I started from and how I've
arrived there in Wave ( exported to Google Docs), but it's in French
(the idea was that Google Docs could help me in translating it to
English, so if you want, I can give you access to an automatically-
translated-by-Docs version).

A nicer way to write the code might be:



return (value instanceof Foo)  ? ((Foo) value).getIndex() : null;

I rarely see {...@code} in GWT sources -- if you do use it, I suggest

just tagging

the first use of a given symbol.



Also, when referencing a method you can use {...@link} instead so you

will have not

only code style but an active link as well.  Be sure to use a # to

separate the

class and method names.


This made me remember reading about this in coding style guides, so I
went and looked around.

The java style in Google and elsewhere indicates the use of {...@code} tags
to visually format code snippets, keywords and such, not just the first
instance.

I also like using {...@link} but using it too much seems to be frowned
upon, with {...@code} being preferred after the first {...@link}. See
http://www.corp.google.com/~codewalk/1259/ for example. {...@code} is
even preferred to code as the former works well with '' and '' while
the latter requires using lt; and gt;.

A quick grep in trunk (outside bikeshed) would seem to indicate {...@code}
usage has been picking up lately (79 files, 1092+ instances).

Reviewers: jgw,

Description:
Adding a null check to ShowcaseGenerator so that we don't try to write
to a public resource that has already been created.  This fixes a bug
when multiple examples reference the same raw source files.
