Re: Handling ClickEvents with custom composite widgets

2010-11-05 Thread Jeff Larsen

here is a hacky example of how to do something similar to what you
want with an event bus.

This definitely could've been put together better, but it should give
you the general jist.

Re: Eclipse Hangs on Compile of GWT?

Rajeev thanks so much for helping me to resolve this.

After looking at that bug report I knew I had no choice but to roll
back GWT or upgrade my Java to Java 6.  So I did the latter.

I went into Preferences in Eclipse, selected Java then Installed JRE's
and added the information for the Java 6 version of Java which hadn't
been included in the list in Eclipse.  I disabled Java 5.  I restarted
Eclipse and then attempted a compile and the compile "worked".  ( That
is, I have compile errors because I attempted to use a StringTokenizer
in my GUI but that is a manageable developer error).  And I can see
the output in the Console within Eclipse.

So the "hang" issue of this thread has been resolved.  Thanks Rajeev.

Re: Handling ClickEvents with custom composite widgets

2010-11-05 Thread Chad

nathan,

When building composite widgets, it is up to you, within the composite
widget, to handle and/or expose whatever events you want. So, if you
want to be able to expose click events for multiple buttons in a
composite, you may be best off doing one of two things:

1) Create a public enum that contains an entry for each of the
buttons. Then, provide a method to get which button was clicked so
that when someone handles the click event, they can query for the most
recently clicked button.

2) Create custom events for each action that can be taken by the
composite widget and you other classes would handle those custom
events rather than a click event.

Option 2 is better, but more complicated. Generally, when you create a
composite widget, the internal widgets are all handled by the
composite. If you want access to all the internals, then you aren't
really wanting a composite widget at all.

GWT 2.1.0 maven asks for com.google.gwt:gwt-dev:jar:windows:2.1.0??

2010-11-05 Thread Yaakov

Hi,

I switched to using GWT 2.1.0 and updated my maven dependencies, so
they now look like this:

2.1.0
3.0.5.RELEASE


com.google.gwt
gwt-servlet
${gwt.version}
runtime


com.google.gwt
gwt-user
${gwt.version}
provided


For some reason, when I try to run mvn clean install, maven looks for
com.google.gwt:gwt-dev:jar:windows:2.1.0, which has "windows" as the
classifier.  Of course, it can't find it since there is no windows-
specific version.

I have no idea why it started using the classifier and how to tell
maven to stop trying to look for classifier specific one. Anyone know
what's going on? I've been using GWT 2.0.4 which also did not use the
classifier anymore and everything worked just fine.

any help would be greatly appreciated!

-Yaakov.

Re: Eclipse Hangs on Compile of GWT?

Thanks for your help!  I have a text file of the generated output
which indicates a deadlock.

I briefly looked at the output and I'll make two remarks,

1 - The machine where I'm developing is not online.  It has no
connection to the internet.
2 - I am logged in as a standard user that is I am not logged in with
full administrator privileges.

There is never any output in the console window within eclipse.  If I
press the red button in the console view
I am able to terminate whatever attempt is being made to compile.
That is, the progress bar stops.

Is there a way I can indicate that I do not GWT Updater to try to
check for updates?

What do you mean "attach it" ? I'm using the form in the website.

Unhandled exception type Exception -- GWT 2.1.0 (not in GWT 2.0.4)

2010-11-05 Thread Barry

Hi --

I have just installed the GWT 2.1.0 (... I was running GWT 2.0.4). Now
my JUnit tests are failing.

It seems that GWT calls to my servlets are taking the
onFailure(Throwable ex) method on my AsyncCallBacks. The exception is
pretty peculiar:

java.lang.Error: Unresolved compilation problem:
Unhandled exception type Exception

Additionally, I have noticed new GWT debug information on my Eclipse
console (below).

It seems like the 2.1.0 compiler has some requirements that aren't
very obvious (... or maybe they're wrong??)

Can anyone add some insight to this?? I'm going back to 2.0.4 for the
time being until I can get a handle on this.

Thanks!

GWT compiler debug that looks like it relates to this problem:

Re: Eclipse Hangs on Compile of GWT?

When it's hanging, drop to a command prompt, and type jps. That should give
you the process id of the compiler process. Then type "jstack ". Copy
that output into a file and attach it.

If you switch over to the "Console" view while the compile is going on, what
do you see? What happens if you hit the red button in the Console view? Does
it terminate the compile?

Eclipse Hangs on Compile of GWT?

Eclipse 3.6 Helios
GWT 2.1
Java 5
Mac OS X 10.5.8

Actually I don't know if it's hanging or not.  But I select the red
toolbox - the compile icon - and I can see the progress bar at the
lower right hand of the screen.  But it just progresses continually.
There is no output and it has been going on like this for several
minutes.  I don't know how to know what is happening if anything.

This difficulty with performing a compile is new with the upgrade to
GWT 2.1.  When I was using 2.0.3 I never had a problem doing a project
compile and I could see the confirmation messages after each
permutation compile in the console.  But now there is nothing.  Just
an endless progress bar.

Please help.  Thanks.

RE: Exceptions not showing up in Dev Mode Panel

That was it, thanks for the quick help. Adding $entry() around my callbacks
fixed it.

Are you using any JSNI that gets called directly from the browser?  Ie,
anything like obj.callback = function() {...};?  If so, you have to wrap any
entry points from the browser into GWT code with $entry, so that would look
like obj.callback = $entry(function() {...});

 

Note that it could be in library code you are using rather than something
you have written -- I don't have a good suggestion for tracking it down if
it isn't something you have written.

How to diagnose IE8 javascript error "stack overflow at line: 0"? ends up in Impl.entry0

2010-11-05 Thread BrianP

I have a GWT 2.0.3 app that runs fine in Firefox and Chrome. But when
run in IE8 I get a javascript error that pops up with 'Stack over flow
at line: 0'.  When stepping through it in debug mode, I end up in GWT
class Impl in the method entry0(Object jsFunction, Object thisObj,
Object arguments).  I was hoping to find more information by looking
at those variables in debug mode, but they didn't really tell me
anything other than its a JavaScriptException, which I already knew.

Any recommendation on how I might get more information on this error?
It seems similar to the error in this thread:

http://groups.google.com/group/google-web-toolkit/browse_thread/thread/caf23e8b06ba74fd/072a3f604be05e81?lnk=gst&q=entry0#072a3f604be05e81

One response there mentions adding an UncaughtExceptionHandler there
to the main EntryPoint class.  Would that help?

Thanks

Re: Problem with DialogBox

2010-11-05 Thread skippy

You can only call setWidget once on a DialogBox.
When I use UI Binder, the compilers tells you that you can not do
this.
However, whe not UI Binder, you get that run time error.

I was adding the HTML widget after a vertical panel rather then adding
it to the vertidal panel.

Thanks.

I hope this helps the next person!

I'm using GWT 2.0.4 and in Dev Mode it seems some exceptions are left
uncaught and show up in the browser instead of in my GWT uncaught
exception handler or in the Dev Mode panel. For example I get a line
like "uncaught exception:

double was returned from JSNI method..." in my Firebug or browser
error console. Is there some way I can get this exception to show up

I'm not entirely clear what you're trying to do but if you have
server-side code (your pure Java stuff) then make sure it is not found
under any of the directories that GWT searches looking for client-side
source code (by default *.client). If you use 
then those directories should *not* contain any server-side code
either.

Re: Handling ClickEvents with custom composite widgets

2010-11-05 Thread nathan

I tried event.getSource() but since I created a custom widget, called
CompositeWidget, and I'm listening for a click in the LeftPanel, I
believe event.getSource() is returning LeftPanel, not the
CompositeWidget. So the contents of the CompositeWidget are not
available from event.getSource(). I could be way off on this.

I think it could have something to do with Event Bubbling. Mentioned
here: 
http://code.google.com/webtoolkit/doc/1.6/FAQ_UI.html#How_can_I_efficiently_handle_events_from_many_interior_Widgets?,
but I don't know how to implement that.

I should mention that I'm new to GWT, so if I'm just doing something
completely wrong or inefficient, please let me know.

I put an example of what I'm trying to do here:
https://code.google.com/p/gwtcustomwidgeteventhandling/source/browse/

When the "Remove" button is clicked, I want that CompositeWidget to be
removed from the LeftPanel, and it's contents removed from the
RightPanel.

I understand I'm probably not explaining myself well, and what I put
up may not be the best example, but thanks for any help.

Re: Showing facebook like button using GWT code

2010-11-05 Thread RPB

Hi Aditya,

The problem is that you can't call a 
widget tag inside of an existing  enclosure (i.e. the
GWT generated js code). See this thread for more details:
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/9a81056219c54470/dbf4fd62e9ed41ef?lnk=gst&q=tag+referencing+the+tweetgrid+widget+in+your+host+#dbf4fd62e9ed41ef

Firefox must have implemented a workaround, but the other browsers
still have this problem.

To get xfbml working you can either use injection as described here:
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/f8a77c93d55aabf2

Or use a wrapper such as gwtfb:

Good luck,
Rob

how to run pure java backend setup code in GWTTestCase?

2010-11-05 Thread Potate

I have a GWTTestCase that validates some GETs and POSTs to a servlet.
The servlet starts up a little differently than the traditional
servlets. So I can't use the builtin unit test servlet bootstrap in
module.gwt.xml.
It's easiest if I can run any pure java methods. When I tried this, I
got compiler errors saying no client side code of my pure java stuff.
Is there a way around this?

Thanks

GWT Designer and Data Binding

2010-11-05 Thread csaffi

Hi everybody,
I happily discovered that Google has released GWT Designer free for
use, and I immediately downloaded it for testing. Unfortunately I
realized that it lacks data binding features to bind data with UI
components... Maybe it will be introduced in future versions, but for
now remains a great lack.

Do you know any way to overcome this problem?

Thank you very much in advance!

Given that the keyCode in keydown and keyup events is 98, it SHOULD be
98 in keypress too. As PPK says, IE has the most "reasonable"
implementation here.
You'll find issues in the bug tracker about these discrepancies, but
really they're not easy to solve (particularly re. repeated events,
and differences between platforms (for the same browser, because of
the differences at the OS level))

GWT Loading the application very slowly

2010-11-05 Thread keyboard_samurai

Hi All,

I am facing a issue which seems to have cropped up in recent times in
our code. We are using GWT 1.7.1 along with GXT 2.2 widget libraries.
Till a few days back the application was getting loaded i.e with the
data within 5-10 seconds ... the cache.html which was getting
generated back then was around 12.8 MB...This being a intranet based
application so we didnt have to worry on the application statup. We
been making continuous upgrades to code base and now the generated
cache.html size is somewhere around 13.5 MB but this has affected our
application startup time to increase from 10 seconds to 1 min 10
seconds. This issue is noticeable only in IE6 and not on other
browsers like FF and Chrome.

On looking via the HTTP Watch i noticed that the 12.8 MB cache.html
file gets downloaded in 2-3 seconds and the javascript statements
executed within the file takes around rest 3-4 seconds,  but the 13.5
MB cache file was getting downloaded in 28-30 seconds and also the
javascript within it was taking around 30 seconds to execute. Is this
normal ? also on comparing the no of lines of code within
the .cache.html file i noticed it has just increased from 98k to
98.5k  ...

not sure whats going wrong here bcoz of which the application has
slowed down considerably ... Can anyone please provide pointers on how
to tackle this issue ?

Thanks in advance ...

Re: CompositeCell and hiding Cells Problem

The default implementation of the render method in CompositeCell wraps each
element in a span.  You could do the same and set the display style property
based on the state, and then you don't need to extend SelectionCell.  While
it isn't required for very simple Cells (that only render a single element),
it makes sense to wrap each Cell in its own parent element.

Thanks,

Re: CompositeCell and hiding Cells Problem

2010-11-05 Thread Ümit

Ah I see ;-)

However I somehow can't access the styles and the span respectively.
The render method of the SelectionCell renders the  tag
directly (I suppose the span is rendered by the CellTable itself).
I solved my problem by extending the SelectionCell and storing a
isVible Flag in it and then adding an additional span around it. The
class looks like this:

public class HideableSelectionCell extends SelectionCell{
  protected boolean isVisible = true;

  public HideableSelectionCell(List options) {
super(options);
  }

  @Override
  public void render(String value, Object key, SafeHtmlBuilder sb) {
if (!isVisible)
  sb.appendHtmlConstant("");
super.render(value, key, sb);

if (!isVisible)
  sb.appendHtmlConstant("");
  }

   public void setIsVisible(boolean isVisible) {
 this.isVisible = isVisible;
   }

   public boolean getIsVisible(){
  return this.isVisible;
   }
}

And in the render method of the compositeCell I set the isVisible Flag
of the cell before rendering it.


Is that the right approach or is there some other way to access the
Cell Span's Style directly ?

Sorry for being so persistent ;-)

Sorry, I was referring to the CSS property display, and I meant "none", not
null.

Rendering the following will cause the span to be completely hidden and take
up no space.

Problem with DialogBox

2010-11-05 Thread skippy

I have several DialogBox popup views in my application,

After adding a HTML object to one, it now opens in peices.  You can
not even tell it is a DialobBox.  Like it is spilling out of itself.

Any help would be great!

Re: CompositeCell and hiding Cells Problem

2010-11-05 Thread Ümit

Thanks John for the quick response.

One question though. I am not sure what you mean with "setting the
display to null". I checked the specific classes (SelectionCell,
AbstractCell etc) but couldn't find anything which allows me to set
the display to null.
Maybe you can specify what you mean with display.

Thank in advance

Instant Messenger portlet

2010-11-05 Thread Shaji

Hi ,
  I am trying to integrate instant messenger gwtapp
with portlet from the link
http://vinaytechs.blogspot.com/2009/09/tutorial-writing-instant-messenger.html
I have got the source code from ryan dews book which works fine in my
local intellij as well as tomcat webapps.
I am able to use instant messaging without any issues in local env and
tomcat web app but not as portlet.
I am using Vignette application portal and GWT 2.0.4 with tomcat
When I deploy into portlet, RootPanel(EntryPoint class) doesn't get
invoked. Here is the code that should be called
RootPanel.get("messengerView").add( messengerService.getView() );
It seems that this issue is related to javascript nocache.js . This
file is being sourced in html/jsp but it seems there
may be path problem.
It seems that messenger service is never called from the javascript. I
have put some messages in the messenger service but it doesn't
display.

Thanks
Mohammed Ahmed

Redirect into a hash-style URL causes a reload in IE

2010-11-05 Thread Andy

We just ran into this and hopefully if you come across this I can save
you from having to go through the same painful day of debugging that I
just experienced.

The issue basically works like this:

Suppose you have a login page at /login and after a successful login,
you redirect into your gwt application at something like /app#token.
When you try to navigate from that page using a Hyperlink which sets
location.hash, it will cause the page to reload instead of navigating.

The reason for this is pretty complicated and I can't say I fully
understand it. It seems to be a combination of 1) a bug in IE, 2) the
HistoryImplIE6 timer, and 3) a timing issue.

It only happened occasionally until I put a 1s sleep in my bootstrap
page. The it happened everytime. Again, you have to come from a 302
redirect into a hash token for this to happen.

Our specific case was actually redirecting query style URLs like /app?
token=foo -> /app#foo

Other developers have run into this before. You can read more about it
here:

http://stackoverflow.com/questions/1985056/response-redirect-with-a-fragment-identifier-causes-unexpected-refresh-when-later

and here:

http://stackoverflow.com/questions/2602260/javascript-location-hash-refreshing-in-ie/3804661#3804661

That second link contains the fix that I used.

I added:

window.location.hash = window.location.hash;

in a script tag at the top of my bootstrap page. I only do this for IE
even though it's probably safe for all browsers.

Native GWT form fields validation framework plans?

2010-11-05 Thread marius.andreiana

Hi,

There is a common, recurring topic about doing form fields validation
in GWT.

Here's a good analysis of the current validation frameworks done by
Brendan
https://wave.google.com/wave/waveref/googlewave.com/w+sVgB2_shE
and more discussions at
http://groups.google.com/group/gwt-platform/browse_thread/thread/6d650f12321dfe93
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/4aeef9d2195f1051/
http://code.google.com/p/google-web-toolkit/issues/detail?id=343

I know native support for validation was started. What are the planned
use cases to support? What's the current status and plans for it? (is
there a wave design doc?) Will it also work with non-RPC backends,
such as REST?

Here are a two use cases besides the basic ones, don't know if these
have been considered:
* some fields might need to interact with server in order to validate.
e.g. on sign up, check if the username entered by user is available
* multiple fields validation e.g. two password inputs, which should
match

Thanks,
Marius

Re: Using REST with GWT

2010-11-05 Thread Harald Pehl

I'm successfully using Restlet in several projects: http://www.restlet.org.
Restlet comes in different editions: GAE, JEE, JSE, GWT and Andoid. So
you can use it on the client and server side.

Re: Using REST with GWT

2010-11-05 Thread bconoly

We actually use a JAXB marshaller on our server to unmarshall
responses from our rest services and then send those objects directly
down to the client via GWT RPC.  The way to accomplish this is to
create a simple GWT project and copy and paste the jaxb source into
it.  Once done create your gwt.xml with the source path pointing to
your jaxb packages and then inherit that in your GWT module.  This
will allow you to unmarshall your responses and send them directly
down to the client for caching.

Yes, but I'm in a VM. Please let me know if there is some data I can

Re: SelectionModel and ListDataProvider are out of synch

The SelectionModel shouldn't depend on the data in the ListDataProvider
because it is independent of the data source.  Consider a SelectionModel
that has an option to select all unread messages.  You probably don't have
all of the user messages loaded on the client, but the unread messages
should be selected as you page through the table, without having to update
the SelectionModel each time you load a new page.  Also, SelectionModels can
be shared across multiple CellTables, each with its own ListDataProvider.

Can you deselect the value in the SelectionModel when you remove the row in
your onClick handler?

Re: CompositeCell and hiding Cells Problem

As far as the SelectionCell, we should have a version that is genericized
and just use the selected index to map to the generic value.  In general, we
probably also need an "EditCell", which is basically a two state cell that
can enter and exit edit mode.  I'm sure that as people use the Cell Widgets,
we'll figure out which Cells are missing from the API.

As for your immediate problem, I think the answer is that you need to
override resetFocus() to do whatever you want.  Composite assumes that all
four elements will be there, so if you override render to change that, then
you need to override resetFocus() to handle the new structure.
 Alternatively, you could render all four elements regardless of the state
and just set the display to null.
