Re: Announcing GWT 2.0 and much, much more...

GWT2.0 ROCKS!!

Seriously I was having a feature that worked perfectly with GWT1.7
in hosted mode,
but when I start running on FF and Chrome, I got strange behavior.

Thanks to the DevMode and plugin I could test it cross browser!

Many many many thanks for that.

Keep up the Good work!

  Unrelated to your question, I also had to manually switch from the 1.7

 That is the default behavior - we do not automatically switch your project's
 SDKs for you, even when you install a new SDK.

handle to window.open opened window.

2009-10-27 Thread Rockster 

Hi,

question:

with javascript you can get a handle to the window that is opened
through the window.open (native javascript).

In GWT the Window.open returns a void.

Is there a specific reason for this ? How to get the handle to the
opened window with native GWT ?

Rokesh

Re: panel in tabpanel cannot be set to invisible

2009-10-15 Thread Rockster 

hi Alex,

thanks for the code-snippet. It worked out as expected.
The tabs are dynamically created, so removing them (and later adding
them) would
require that I keep references in memory to later make it visible
again.

So this code is really helpfull!



On Oct 15, 1:26 pm, Ian Bambury ianbamb...@gmail.com wrote:
 I just ran a quick test, adding and removing the same item to a tab panel
 25,000 times in Chrome, GWT1.7 - no memory increase.
 Just making the tab disappear means that you can't release the memory used
 by the corresponding widget if you wish.

 Can you post some code that demonstrates your memory increase problem?

 2009/10/15 alex.d alex.dukhov...@googlemail.com





  Adding/removing tabbars causes increase in memory usage and with no
  possibility to trigger garbage collector it kind of sucks. Making tab
  invisible is actually easier than it sounds:

  public static void setTabVisibility(TabPanel tabs, int index, boolean
  visible)
  {
   try
   {
      if (index = tabs.getTabBar().getTabCount() || index  0)
         return;

      // Native Google implementation of TabBar uses an
  HorizontalPanel,
      // so, the DOM primary element is a table element (with just one
  tr)
      Element table = tabs.getTabBar().getElement();
      Element tr = DOM.getFirstChild(DOM.getFirstChild(table));
      // (index + 1) to account for 'first' placeholder td.
      Element td = DOM.getChild(tr, index + 1);
      UIObject.setVisible(td, visible);
   }
   catch (Exception e)
   {
      System.err.println(e);
   }
  }

It is customer requirement so we want to make it invisble.
I know what you mean, but other visible tabs (that are not in scope
for this user) could confuse the user.

So Again, how do I make  the tab invisible ?

Hi Sumit,

this really helped! Thanks, the compilation is even faster now and I
don't need the -Xss argument anymore.
I really spend a lot of time on this and I'm glad that you guys fixed

But how come you didn't find this before releasing the GWT 1.6.4 ?

 Hi Rockster,
 Passing in a stack size of 128M seems awfully huge. How much memory does
 your machine have exactly? You might want to try compiling with a more
 reasonable stack size, say -Xss2048k or -Xss4096k.

 Scott has been working on fixing the issue with the compiler requiring too
 much stack, so if this still doesn't solve the problem, you might want to
 try the patched dev JAR attached to Issue #3510 as a workaround for now.

I don't want to think of a situation where you have to install plugins

But doesn't run on any device (read: phone!)

Now I can walk with my iPhone and access almost any application.

Re: How to debug IE6 crash

2009-03-12 Thread Rockster 

I have the same problem now with IE6 (and seems to be also in IE7).

Somehow, when you close the IE window, an error message pops up
with the message that an error occured in the script of this page.

Do I want to continue ? 

If you click yes, and go to that URL in a new window (since the
previous window
had to be closed in order to get the error message) the program
continues to perform as expected.

IE6 is the worst browser! (Maybe IE7 is even worse)

Firefox, opera, Chrome, Safari all perform as expected.

 Thanks Adam. I suspected that may be the only way.

 After some persistence using the comment-out-and-run method I've got
 the bottom of the issue.

 I was updating results in my app by replacing the FlexTable with a new
 FlexTable on every update. Which I guess defeats the whole point of a
 FlexTable!
 I've now reworked things so that I create one FlexTable on loading the
 app and each update only alters the relevant rows in the table.
 IE6 is now crash free again.

   I'm attempting to use MS script debugger with no luck. The error isn't
   caught by script debugger (or maybe it is, but it crashes before I can
   view it) and when I try and step line by line IE6 still crashes before

   The problem is, how do I find the problem?!

   Anyone got an idea on how to proceed?

How to Recover from java.lang.IllegalStateException: Should only call onDetach when the widget is attached to the browser's document

2009-03-10 Thread Rockster 

Hi,

this problem is highly annoying. I'm dynamically setting panels
contents with this code:


   if (w instanceof HasWidgets  ui
instanceof HasWidgets){
 // clear the elements
HasWidgets target = (HasWidgets)w;
target.clear();

HasWidgets source = (HasWidgets)ui;
IteratorWidget itr = 
source.iterator();
while (itr.hasNext()){
target.add((Widget)itr.next());
}
}

The exception occurs at target.clear() statement


This works perfectly in Firefox, Chrome, Safari, but Of course IE6/7
is the problem (apparently the screen was still building)..
I noticed that this happens if the clicking fast (so that setting the
panel to another occurs)
results in this behavior.

Is there a workaround for this ? Do I have to change something.


Regards,
Rockster

Re: What are your thoughts on Cappuccino and SproutCore?

2009-02-27 Thread Rockster 

Looks nice though.
I checked the video and was impressed

again another one...)

 Cappuccino and SproutCore have been around for a while and they are
 really starting to make an impression on web developers.

 I've been using GWT in one project for 2 months, and I'm loving it.
 However I tried out Cappuccino, just to get the felling of it, and I
 was truly impressed. I was able to re-design the project's UI in
 Cappuccino in one week, and it seems to me that a lot of my server
 side code can be re-utilized if I use something like cp2javaws
 (haven't tried it).

 So, my question to you guys is how will GWT compete with Cappuccino or
 SproutCore, (and I'm not even mentioning JavaFX), and if you have
 anything planned to extend GWT capabilities of building really rich
 UIs just as easy as Cappuccino.

 Don't get me wrong, I'm a truly GWT lover. In my opinion GWT is
 superior in both performance and code security (minimization /
 obfuscation), but right now I'm really tempted to throw away 2 months
 of GWT work...

Re: Struts+GWT

2009-02-13 Thread Rockster 

I totally agree with Gregor.

Struts is for navigational purpose in Classic WebApplications (let's
call that Web1.0 technology).
Struts became an industry standard in the Web1.0 era.

The programming model behind GWT is like it was before web: Just
create an application and don't worry about
request/response etc. Everyhing happens in that application.

My suggestion to you:

A struts appliction contains Actions. The Body of the Actions should
in fact NOT contain any business logic.
That's where the SOA kicks in.  You might have the real logic in the
body of another class.
You can reuse that class

So (in the old case)

MyAction extends Action {

  MyService myService = new MyService()
   execute(req,resp){

   // of course you have here some navigational actions
myService.businessMethod(...)

   }

}


In GWT this is the RPC/RPCImplementation/RPCAsync combination.

RPCImpl implements RPC{

doSomething(){

   }

}

   There you can reuse your MyService class.


BTW: MyService is nothing fancy, just a class (best with Interface and
separate implementation).
From this point on you can use anything you want (Spring,
hibernate,etc!).

Good luck,
Rockster

Re: Who's Using GWT?

2009-01-13 Thread Rockster 

Hi,

Website: http://www.qafe.com
Tagline: Building Enterprise Applications  Made Easy
Status: beta, http://demo.qafe.com  is live !

Summary:
QAFE is a framework to easily create Enterprise Applications  with all
requirements that are needed in these environments. It's fully
declarative
except for the complex logic (you write that in Java/Database stored
procedures). There is a declarative UI and the interaction
with the backend is also declarative. So no javascript/java/complex
architectures.
The architecture is divided in several and design patterns are applied
under
the hood. Data transfer from any datasource (Java source/Database) is
generalized
in such a way, that even this is easy. Idea is NOT to bother
(database) developers
with object orientation (it's a totally different mindset).

The UI is abstracted from any technology, which makes it possible to
render
any presentation technology. Currently to GWT and (not final) Adobe's
Flex (or any other presentation technology in future).

The SOA consumes java (service) classes with easy as well as the
interaction
with databases (tables/stored procedures/ custom SQL, etc). There is
no need for Java/javascript.
Just XML

We are setting up the site. In the http://demo.qafe.com
you can try out the code from the Showcase in the QAFE Labs Try
memenu.
So in fact with QAFE you can create any application with ease.

GWT made so much possible. Without GWT this project would not work.
GWT has a clean base and doesn't rely on javascript libraries.
Optimized output is super.

Looking forward to your feedback.

Rockster.

Re: Need for a great GWT GUI library

2008-12-22 Thread Rockster 


I'm using gwt-mosaicand it's very good. SmartGWT is in fact a

For native GWT, go for gwt-mosaic.

 Hi Juan,

 Ext GWT (aka gxt, previously MyGWT) is a full GWT solution (no
 wrapping JS library). It provides :
 - containers and layouts
 - MVC layer
 - complete look and feels
 - rich set of widgets (including grids, drag and drop...)
 - form data binding
 - lazy rendering
 Drawbacks :
 - bugs : as the library is young, there are some bugs, but they are
 quickly fixed when you post a ticket (and there are almost always
 workarounds when you can't wait).
 - slower but not slow : In hosted mode, start time will be slower than
 a vanilla GWT app, but I don't get any performance issue once the
 app is launched
 - GPL license or pay (it can be a drawback for people who neither can
 release under GPL nor can pay)
 I use it since April 2008 in an internal app (223 classes for the GWT
 side) and it saves me a lot of time. I don't have to write a line of
 HTML/CSS code.
