Re: CellTree How to render "different" cell types at a given level ?

[Subhrajyoti Moitra]

http://google-web-toolkit.googlecode.com/svn/trunk/user/javadoc/com/google/gwt/examples/cellview/CellTreeExample2.java

see the code for this example. What you describe is implemented in the
example below, with 3 levels, (ie 3 different objects).
HTH.

Thanks,

CellTree How to render "different" cell types at a given level ?

[metalhammer29a]

How to implement this use case, which is also mentioned in Google
documentation ?
"Each node has a Cell of a specific type; usually, all Cells at a
given level are of the same type, but that isn't required." [1]

I am using GWT CellTree.
public static class MyFolderTreeModel implements TreeViewModel

@Override
public  NodeInfo getNodeInfo(T value)

in this method, I check each Node value

if( value instance of Folder)
//data provider
//render

return new DefaultNodeInfo(dataProvider, cell);

The problem is, each Folder can contain child "Folders" AND "Files".
but I can return "only one" from getNodeInfo.

Does anyone know how I can get around this problem ?

How do you style td elements in a CellTable?

[James Moore]

I'd like to apply styles like the ones in CellTable#renderRowValues,
but based on some conditions of my own.  The current set of a dozen or
so styles looks completely hardcoded in that method; there's no logic
in renderRowValues I see that would let me get in there and apply my
own style in addition to the dozen or so that are there.  Ideally I'd
like renderRowValues to just ask the cell what styles should be
applied to the td - is there a way to do that that I'm missing?

Re: Calling EJB from RPC method

[Gaurav Vaish]

Hi,

I am not quite sure what's your EJB configuration and how are the
EJB's being loaded... but to me it seems that in the GWT-Service
method addCustomer you're working with a null pointer.

Note that GWT-RPC (server-side) will not automatically setup the bean.
You'll need to use the JNDI etc in your server code to ensure that the
bean is available.


Disclaimer: I am not an EJB expert. Albeit, I hate them
passionately. ;)

Re: equals and hashCode methods server and client side

[metalhammer29a]

You can use gwt-hashcode-equals, which is  port of HashCodeBuilder and
EqualsBuilder from the Apache Commons project to Google Web Toolkit.

http://code.google.com/p/gwt-hashcode-equals/

your hashCode, equals,  would become a lot more cleaner too.

equals and hashCode methods server and client side

[Sydney]

Hello,

I organized my project using a standard approach:
src/client
src/server
src/shared

I put my model classes into src/shared because they are used in RPC
calls. In some of them I generated the equals and hashCode methods
using eclipse. Then when I run my app I have an exception about
Float.floatToIntBits() method that does not exist in Float. I
understand why I got this exception because that method is not
supported client side. So I was wondering how I could replace that
method.

Snippet of hashCode(); alpha and beta are defined as float.

@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + Float.floatToIntBits(alpha);
result = prime * result + Float.floatToIntBits(beta);
result = prime * result
+ ((timestamp == null) ? 0 : timestamp.hashCode());
return result;
}

SuggestBox is overengineered

[George Georgovassilis]

So I've been on a webapp of mine that does RPC, Google Maps, MVP, uses
a ton of stock and homebrewn widgets and plenty of other things,
touching most of the GWT API and, like in every other GWT App I've
done so far it also uses SuggestBox. And like in every other GWT App
I've written, I come to battle the usual cross browser compatibility
issues, double events firing, display issues etc [1] that haunt
SuggestBox.

A discouraging look at the SOYC report reveals that a whooping 17% of
the code volume is courtesy of SuggestBox & friends, so I decide to
write a (simpler) version (something like they [2] are doing) which
results in a 15% reduction of the gzipped code.

On a side note: this made me really appreciate the ingenuity of the
original SuggestBox author - there is a myriad of details one needs to
take care of, for instance keeping track of focus/blur events between
the listbox and textbox.

Re: Google's CellTree documentation - CellTreeExample2.java won't compile !

[John LaBanca]

We're working on GWT 2.1.1 in the GWT 2.1 release branch:
http://code.google.com/p/google-web-toolkit/source/browse/#svn/releases/2.1

All GWT 2.1.1 features are also available in the trunk.  If you would like
to preview new features, you can checkout the 2.1 release branch or trunk by
following these instructions:
http://code.google.com/webtoolkit/makinggwtbetter.html#workingoncode

Remember that both trunk and the release branch are less stable than an
actual release.  Also, we always upload a release candidate (and sometimes
beta) jars before we release, so you can also preview those jars.

Best way to handle Hierarchical structures/queries in GWT + GAE Datastore

[metalhammer29a]

I have a Hierarchical structure, similar to Folders/Directories.

I am going to use CellTreeWidget for data presentation.
and planning to use RequestFactory/JDO/Google Data Store /GAE for
persistence/data access.


What is the best way to deal with this situation?

two approaches for the model that I could think of:

Approach #1:
class Folder {
String id;
String name;
Folder parent;
}

or
Approach #2:
class Folder {
String id;
String name;
Folder parent;
List children; // here we are keeping/references to the
children

}

with Approach #1:

Query #1: we Select Folders whose parent is null --> this gives us
the  list of top level folders

now that we have top level folders, every time user selects an item,
we can fetch child folders from the server

Query #2:
user selects a folder --> selects folders whose parent is the selected
folder

my concern is this approach could be slow, as upon each slection, user
has to wait for children (if any) to be fetched.

the alternative is to use Approach #2:

with this, since we are having references to children folders,when
user selects an item,
we already have its children. somehow like being one step ahead from
the user.


or better yet,
is is possible to issue Hierarchical Queries on App Engine datastore ?
so that with one single query, we can get multiple levels deep into
the tree structure ?

Re: Google's CellTree documentation - CellTreeExample2.java won't compile !

[metalhammer29a]

Thank you.

are GWT 2.1.1 features available to the public ?

Would be nice to look at what is going to be added in future releases,
and be prepared for changes.

I don't think I could find GWT 2.1.1 in the trunk.

Re: CellTable, how to create a cell with custom listbox

[John LaBanca]

You can create a Popup containing your list of options (some people have
used a vertical MenuBar as a list of selectable items).  When the user
clicks on the Cell, open the Popup.  When they select an option, close it.
 DatePickerCell is a good example of this technique.

We'll probably include a CustomListBoxCell in a future version of GWT, but
it isn't on the agenda for GWT 2.2.

Re: Google's CellTree documentation - CellTreeExample2.java won't compile !

[John LaBanca]

GWT 2.1.1 will add the Context parameter to Cell methods.  Its a breaking
change, but it allows us to pass the row index and cell index, and add more
variables in the future without another breaking change.

You can use the following example that is compatible with GWT 2.1.0.
http://google-web-toolkit.googlecode.com/svn/tags/2.1.0/user/javadoc/com/google/gwt/examples/cellview/CellTreeExample2.java

 Including a table in a Cell shouldn't affect events.

UiBinder Internationalization

[Srividhya Ramachandran]

I am having trouble with UiBinder Internationalization. I create a
LocalizableResource.properties file with messages and use keys for the
messages in the **.ui.xml files. Basically followed the steps in showcase
sample project and find that the messages are not being picked up from the
properties file, but still come from the ui.xml files.
Anybody experienced this problem before?
I read somewhere that in previous versions of GWT (i am using 2.1) the
messages for default locale always came from the ui.xml file even though you
provide a  .properties file. Is this still an issue? Thanks for taking the
time to read and reply.

MVP place/view/page navigation control: hardcode vs. declarative

[Michael W]

Since GWT 2.0, Google provides MVP pattern to develop large scale GWT
application.
However, the logic of navigating to the next view/page is hard coded
in the Java code.

For example of GWT 2.1.0 HelloMVP, first it requires to register all
places(view/page) with AppPlaceHistoryMapper, then the navigation
logic is embedded inside ViewImpl.

In order to navigation from hello to goodbye, the following piece of
code is needed in HelloViewImpl:

   listener.goTo(new GoodbyePlace(name));

As we know, for server side development, we can use struct-config.xml
for Struts and/or spring-servlet.xml for Spring MVC to control the
navigation.

Just wonder:
Is there any reason that MVP does not provide a similar approach like
Struts/Spring by using declarative config of navigation?

New book: Google App Engine Java and GWT Application Development

[Supercobra Thatbytes]

hi,

Some of you may be interested in a book I co-authored that has just
been published:
"Google App Engine Java and GWT Application Development" by Amy Unruh
and Daniel Guermeur, from Packt.

The book describes many of the techniques and approaches used to
develop GAE+GWT applications, and includes an app developed
throughout  the book as a running example. It has a particular focus
on some of the technologies useful for building scalable social-media-
oriented applications, including: MVP and UiBinder, using the Channel
API for push, using Facebook and Twitter OAuth for authorization, JDO,
the Task Queue, transactions and transactional tasks, Memcache, and
XMPP.


This is the Packt Publishing link:

Re: GWT JavaDoc failures KeyPress v. KeyDown

[Greg Dougherty]

Hi David,

I must humbly disagree.  Maybe I just don't see enough Open Source
projects, but MySQL, which I use on a regular basis, has documentation
that is easy to search, has it all in one place, and does a good job
of explaining what's going on.

The GWT documentation, OTOH, in my experience NEVER gives you a
COMPLETE explanation on how to do anything.  Which I find very
frustrating, especially since I assume that, before you folks claim to
have created a feature, you've actually TESTED that feature, which
means that somewhere you must have the code that works out that
feature to its fullest extent.  Given that it's an open source
project, I honestly fail to see why you wouldn't make that test code
publicly available.

But if you have, I can't find it anywhere.

Take the CellTable for example.  Clearly the purpose of the thing is
to have something that lets you download chunks of data from a server,
and display it quickly.  So, what do all the "examples for how to use
a CellTable" show?  How to display local data.  Is there ANYONE,
ANYWHERE, who's going to use it for that purpose in an actual GWT
application?  So why is that the "example"?  Presumably someone's
actually written a GWT app that gets information from a servlet using
RPC.  Where is that code?

Or, take a really frustrating case, because it was SO close to being
great documentation.  You've got a nice code sample at
http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsHistory.html
You've got an entirely different one in the history JavaDoc.  Any
reason why they couldn't be combined in one example, that includes the
sample versions of addSelectionHandler and addValueChangeHandler that
the JavaDoc lack, AND includes the rather vital
History.fireCurrentHistoryState (); that the "Coding Basics" lack?

Personally, if I were writing things for an open source project, it
would be because I actually wanted people to use the things I was
writing.  So what's the point of writing great code if the
documentation is so poor that few people can figure out how to use it?

As for adding things to the project, there's a couple of problems with
that:
1: The places where I want something added to the documentation are
places where I don't know what the heck is going on.  So I'd be the
last person to add it.
2: My contract specifies that everything I write belongs to the people
paying me.  So I can't take the code I've written and add it to the
GWT code base / documentation, because I lack the rights to it.
3: I'm working 50 hours a week writing code.  By the time I get home,
I lack the mental energy necessary to write code for any purpose.

If you want to email me off list with a simple way to update the
JavaDocs with what I've learned and think I can legally offer, there's
some things I'd be happy to update.  But the key word there is
SIMPLE.  If it requires jumping through a lot of hoops, then I've got
much better things to do with my time.

Respectfully,

Greg

Re: GWT JavaDoc failures KeyPress v. KeyDown

[Brian Reilly]

Greg,

For what it's worth, I had very similar feelings when I ran into a very
similar problem. (I was trying to get consistent behavior when pressing
enter or tab. Tab is a tricky one because different browsers do different
things with different events to handle element focus. Hint: in Safari, you
may have to call event.preventDefault() in order to prevent focus shifting
to funny places, though that might depend on whether or not you're also
trying to manage focus).

To make a long story short, this is a very problematic area when it comes to
cross-browser compatibility. If you're survived it (despite frustrations),
you're in pretty good shape.

This is probably one of the worst corners you'll find in GWT because it
actually affects functionality. There are still issues with things rendering
differently, but at least those are only visual. There's not much you can do
about that other than to learn how to deal with some and avoid the others.

There are some areas where GWT does hide some of the complexity (element
visibility, for example), but GWT is more about leveling the behavior of
JavaScript than the DOM.

Google's CellTree documentation - CellTreeExample2.java won't compile !

[metalhammer29a]

In Google's documentation for CelLTree,
http://code.google.com/webtoolkit/doc/latest/DevGuideUiCellWidgets.html#celltree

the sample code provided for CellTreeExample2 doesnt compile:
http://google-web-toolkit.googlecode.com/svn/trunk/user/javadoc/com/google/gwt/examples/cellview/CellTreeExample2.java

the problem is in :

Cell cell = new AbstractCell() {
  @Override
  public void render(Context context, Composer value,
SafeHtmlBuilder sb) {
if (value != null) {
  sb.appendEscaped(value.getName());
}
  }
};

and

ListDataProvider dataProvider = new
ListDataProvider(
((Composer) value).getPlaylists());
Cell cell = new AbstractCell() {
  @Override
  public void render(Context context, Playlist value,
SafeHtmlBuilder sb) {
if (value != null) {
  sb.appendEscaped(value.getName());
}
  }
};


IDE suggests:

- The method render(AutoBeanVisitor.Context,
ApplicationMain.Composer, SafeHtmlBuilder) of type new
AbstractCell(){} must override or implement
a supertype
 method

- Context cannot be resolved to a type


the problem is "Context".
do you know what is the correct type for Context ? is it
AutoBeanVisitor ?

Getting a user Enter key

[Greg Dougherty]

Ok, the tutorial says that to get a user pressing an enter key in a
TextBox you should write something like the following:

http://code.google.com/webtoolkit/doc/latest/tutorial/manageevents.html

public void onKeyPress (KeyPressEvent event)
{
charkeyPress = event.getCharCode();
int keyCode = keyPress;
if (keyPress == KeyCodes.KEY_ENTER)
goToRecord ();
}

Unfortunately, when I do that, I get a keyCode of 0 for  Enter, Tab,
and Left Arrow (the keys I tested), while I get the actual key when I
type a number key.  What gives?  Is the tutorial wrong?  If so, what
should I be calling?

TIA,

Greg

Re: Ship a GWT app as a desktop app with local server?

[Brian Reilly]

As much as I like GWT, I think it might not be the right tool for your
situation.

Your two use cases are:

* Remote data and compute
* Local data and compute (unless you meant that desktop use would use remote
compute, but I don't think so because that would require transmitting local
data to the server)

While being able to reuse the UI (for both consistency and
development efficiency) is a good goal, it sounds like your real substance
is the analysis algorithms. What language are those implemented in?

Assuming you're using Java, you do have some options. A separate desktop
application is one of them. You could also go with a webapp and use
something like Jetty on the desktop, like Gaurav suggested. I think that
would be awkward in desktop mode as you'd have two processes to worry about,
the jetty server and the browser, which may be tricky to do well and may be
confusing to users. Plus your access to the local filesystem is going to be
awkward. You'd probably have to present an upload widget to invoke the
system file dialog, but then just pass the file path to the locally running
server for it to open directly (which hopefully it would be able to do...)

You might instead want to look into using Swing, SWT, JavaFX, or Apache
Pivot. I went to a NEJUG talk about Pivot earlier this year and was pretty
impressed with it. Some things even reminded me of GWT.

One catch, though... I'm not sure if it's just their demos, but they require
Java 6, and they don't quite work in-browser on Mac OS X 10.5. Supposedly
they do work in 10.6, but I haven't upgraded yet so I can't confirm. (See
http://mail-archives.apache.org/mod_mbox/pivot-user/201006.mbox/%3c8d8726ba-54bd-4745-87d1-40d067b34...@mac.com%3efor
the response to my question on the Pivot mailing list.)

Re: onResize issue with IE 7

[PhilBeaudoin]

I'm working with Mayumi on this bug and I'm pretty sure there is a
problem somewhere in GWT. In our case, it happens with deeply nested
layout panels. To reproduce the bug, we removeFromParent() a panel in
the middle of the hierarchy and later re-add() it. At that point, the
children of the re-added panel have wrong width/height and their width/
height does not update when resizing the browser window. (Again, only
in IE7.)

I have fixed the problem by calling forceLayout() recursively on the
nested layout panels. I do this by calling the following method on the
reattached panel right after we add() it:

private void forceLayoutRecursive(Widget widget) {
HasWidgets parent = null;
if (widget instanceof LayoutPanel) {
((LayoutPanel) widget).forceLayout( );
parent = (HasWidgets) widget;
}
if (widget instanceof DockLayoutPanel) {
((DockLayoutPanel) widget).forceLayout( );
parent = (HasWidgets) widget;
}
if (parent != null) {
Iterator iter = parent.iterator( );
while (iter.hasNext( )) {
Widget child = iter.next( );
forceLayoutRecursive(child);
}
}
}

If I had more time I would work on a simple test case that reproduces
the problem and file an issue... :)

Re: GWT JavaDoc failures KeyPress v. KeyDown

[David Chandler]

Hi Greg,

Prior to joining Google, I thought (and still do think) that the GWT
developer guides are actually pretty rich for an open source project and
many of the Javadocs, too. Of course, there are always holes and we welcome
constructive feedback through the issue tracker.

GWT is open source, so I hope you will contribute Javadocs as you find
things that can be improved.

Thank you.  That' lets me know which one I want to use.

If I knew JavaScript and DOM, or, for that matter, even WANTED to know
JavaScript and DOM, I wouldn't be using GWT, I'd be writing the
JavaScript myself.  No?

The whole point of using something like GWT is that it lets a Java
programmer write a web app w/o having to learn all the crap that
normal web app writers have to wade through.  That's certainly why I
spent the time and effort to learn GWT.  For that matter, I presume
that the people writing things like the KeyPressEventHandler DO know
JavaScript and DOM.  So, really, how hard is it for them to put that
knowledge into the documentation?  Isn't that what the documentation
is THERE for?

I write a JavaDoc header for every routine I write.  And the point of
that header is to explain why it is that someone would be calling that
routine, and what they'll get by calling it.  To my mind that's the
MINIMUM that should be in any JavaDoc, and if you're not going to
cover that, you should stop wasting time and just not write anything.
Do you disagree?

What % of the GWT JavaDoc actually answer those questions?  1%?  10%?

Re: GWT JavaDoc failures KeyPress v. KeyDown

[Jim Douglas]

It can help to remember that GWT generates JavaScript, so GWT concepts
(widgets, events, etc) generally map pretty much directly to
JavaScript concepts.

In this case, you can start with a google search for those events:

http://www.google.com/search?q=keydown+keypress+keyup

The first item in that search is excellent:

http://www.quirksmode.org/dom/events/keys.html

Bookmark and use this site [quirksmode.org, run by Peter-Paul Koch
(ppk)] as a regular reference.

This reference page + test page is also excellent:

http://unixpapa.com/js/key.html
http://unixpapa.com/js/testkey.html

FWIW, JavaScript and Java key events work very similarly, so the Java
KeyEvent documentation is helpful from a conceptual point of view:

http://download.oracle.com/javase/6/docs/api/java/awt/event/KeyEvent.html

Java KEY_PRESSED = JavaScript keydown
Java KEY_TYPED = JavaScript keypress
Java KEY_RELEASED = JavaScript keyup

Re: GWT JavaDoc failures KeyPress v. KeyDown

[Jeff Schwartz]

KeyPress - triggered when the user presses a key and releases it (key down
and then key up)
KeyDown - triggered when the user presses the key (key down)

Perhaps the documentation assumes some prior knowledge of javascript and dom
events and though GWT tries to shield the developer from much of it it
cannot do so 100%.

GWT JavaDoc failures KeyPress v. KeyDown

[Greg Dougherty]

This is my first entry in what will be a continuing series of pointing
out GWT JavaDocs achieving Microsoftian levels of "saying everything
while explaining nothing."  Why? Because if you're going to actually
write documentation, it shouldn't be totally worthless.

KeyPressHandler: Handler interface for KeyPressEvent events
KeyDownHandler: Handler interface for KeyDownEvent events

KeyPressEvent : Represents a native key press event
KeyDownEvent: Represents a native key down event

Does anyone believe this "documentation" provides anything of value?
I sure don't.  What I want to know is what is teh difference between
these two things?  What, EXACTLY, is a KeyDownEvent?  How does it
differ from  KeyPressEvent ?  When would I use one, when would I use
the other?  Which one should I use if I want to fire off a command
when the user hits Enter or Return?

The first place most people are going to look to answer these
questions is the JavaDoc.  If you're programming in Eclipse (and, if
you're not, you're wasting a lot of time and killing your
productivity), you get the JavaDoc whenever you hover over one of
these objects, which means that the fist place to put anything and
everything the user needs to know is there (you want to put it other
places, too?  Great.  Disk space is cheap.  Programmer time is not).

So, what IS the difference between the two?  Anyone know?  Because
while I could make a guess, I'm not paid to guess, I'm paid to know.
(And yes, I'd be quite happy to pay ~$50 to get JavaDoc for GWT that
were something more than the pointless repeating of what's already
there.  Anyone selling something like that for GWT 2.1?)

Re: How to install GWT Designer

[Basi Lambanog]

Thank you for your reply.

I'm new to Eclipse (though not to IDEs). When I start Eclipse I don't
see the expected menu items like File Edit Navigate, etc. Instead, I
see the Package Explorer perspective and a bunch of icons (related to
cutting and pasting along the top where the menu items should be.

I installed the Eclipse IDE for Java developers Helios package. Mac
Mini OSX 10.6.

I'm missing a menu. I can't order anything. I'm hungry!

Thanks.

CellTable composite Header

[manstis]

Hi,

I'd like to make a composite Header for CellTable.

My requirements are:-
* Multiple rows
* ColSpan in one of the multiple rows
* Multiple Clickable elements in each TH's TD

Naively my plan was to generate the required HTML in the Header's
render method and hook up clickHandlers to some of the elements;
however (obviously) the render method only returns HTML which is used
by CellTable to populate the inner HTML of elements already created
(namely the TH and TD elements).

Furthermore to provide the multi-row\colspan requirements I planned on
using the same Header for all columns (so CellTable spans all columns)
and generate HTML for a nested table - with multiple rows\colspan etc.
Provided the nested table's column widths match those of the CellTable
and I override CSS to remove padding and margins it gives the required
effect.

I also found that click events do not get raised when the Header
contains HTML for another table.

So, some questions:-
* Does anybody have advice on implementing composite headers?
* Can you attach Handlers to HTML elements created in a render method?
* How can I get Click Events to pass through to a nested HTML table?
* Would I be better off writing my own Widget rather than use
CellTable?

Thanks for reading this far.

Mike

Re: onResize issue with IE 7

[Magnus]

Hi Mayumi,

I am happy that there is someone else struggling with this problem.

Well, within onResize I just call resizeLater:

 public void onResize()
 {
  super.onResize();
  resizeLater();
 }

Ans resizeLater just schedules this action to be performed later:

 private void resizeLater ()
 {
  Scheduler.get().scheduleDeferred
  (
   new ScheduledCommand()
   {
public void execute()
{
 myResize ();
}
   }
  );
 }

And in myResize I do the resize actions themselves. When this method
is called, the new sizes are available through getOffset[Width|
Height].

But this is not a solution for me, since I have to deal with this
stuff in every subclass.

HTH (but I hope that someone helps me .-))
Magnus

Ship a GWT app as a desktop app with local server?

[Brett Thomas]

Hi all, sort of an off beat question: what's the best cross-platform library
for a local web server, that could effectively make a standard GWT app into
a desktop app? Ideal would be super light weight, and just allow users to
run the app offline, with local data. Language could be Java, C++ or Python.


If curious about why such a library would be desired, some background at the
end of the email...
Thanks for the help,
Brett

***
Background:

I'm about to build an app for researchers to browse and analyze large
scientific datasets. We want to permit two uses:
-- Web version: users can browse/analyze common public datasets over the web
-- Local version: users can do the same browsing/analysis on their own data
set, *without* transferring the data to the server.

The plan now is to build a desktop app for this. I'd love to make it a
browser app instead, with GWT as the front end. If we went this route, we'd
have to provide some software download for the local version. Here are the
options I can think of:
1 -- Local version is a completely separate app. Hope to avoid this so users
get the same interface on web/local.
2 -- Use Gears (or Adobe Air). Avoided because that would require
transferring server side analysis code to javascript (or Actionscript).
(Right?)
3 -- Ship an executable that starts a local web server. User views app at
http://localhost:12345/ in the browser.
(Any others I'm missing?)

I am trying to assess the feasability of #3. The ideal workflow of our app
would be:
-- Researcher checks out our site in the browser and tries it out. Likes it,
clicks the "Try this on your own data" button
-- Downloads executable with mystery web server described above :)
-- Double clicks executable and a minor GUI shows up with a "Get started!"
button
-- User clicks, and the app is loaded in the browser at
http://localhost:[whatever
port]/. The app looks the same as it did online with the same functionality,
except the "Select data set" option lists local files...

Spring mappings with 2 GWTapp - upgrade 2.0 to 2.1

[Tom]

Hi,

I developped two GWT applications app1 et app2 with spring in GWT 2.0
I do some stuff in app1 then I go on app2 with the line :

Window.open(GWT.getHostPageBaseURL()+"app2.html", "_self", "");

These two apps are in the same webapp. Moreover I defined the
mapping :












The application worked fine with GWT 2.0.
The problem occurs when I upgraded GWT to  2.1.

the mapping works but the link between app1 et app2 failes. I get the
error :

springWebapp: ERROR: The serialization policy file '/avenanceportage/
6C7454447EB3F5DE8F334854ABD1DC32.gwt.rpc' was not found; did you
forget to include it in this deployment?

used.  You may experience SerializationExceptions as a result.

The file  '6C7454447EB3F5DE8F334854ABD1DC32' doesn't exist in any

Re: gwt-maven-plugin / "google plugin for eclipse" / working for anyone?!?!

[PhilBeaudoin]

A valuable resource that has helped me quite a bit are the POMs from
Harald Pehl in his various open source projects. Check out:

Super POM with global settings:
http://code.google.com/p/pehl-parent/source/browse/trunk/pom.xml

Super POM for Piriti:

We are in the process of migrating gwt-platform to Maven, so you might
find some information in there too:

Re: To smart GWT or not

[Sanjiv Jivan]

Jaroslav,
If you're happy with GWT that’s great but please do not make such vague and
baseless claims about Smart GWT. Legitimate bugs reported are fixed really
quickly and existing users can attest to this. Smart GWT currently has
around 42 open defects with a majority of them being low priority, and 16
enhancement requests ( http://code.google.com/p/smartgwt/issues/list ).
Considering the depth and breadth of features provided by the framework this
is a pretty low number of defects.

3 of the 7 issues that you filed were invalid, and 2 defects that were fixed
and the remaining 2 were marked WontFix since they were trivial pieces of
functionality that the user could easily implement.

http://code.google.com/p/smartgwt/issues/list?can=1&q=reporter:jaroslav.zaruba

And
when you were advised how to implement a warning dialog before record
deletion on this issue that you filed  (
http://code.google.com/p/smartgwt/issues/detail?id=325 ), you responded by "you
are sad". Nice way to show your appreciation when using a free product.

You are so kind!  But that won't be necessary.


As a die hard Unix/Linux user for many years, I put on my "cloak of
invisibility", made sure no one was around/looking, and discretely
used a Windoze machine.

Running IE on it allowed me to print.


Thanks for the work around!

Doesn't  Google need to do something about this?  Seems that printing
of those docs should work on most modern browsers ... including their
own "Google Chrome" ...

Re: Safe Html check?

[Philip Rogers]

As a best practice, it is usually best to "unwrap" (call
safehtml.asString()) as close to the value's use as possible. When
migrating you can replace many String occurrences with SafeHtml, and
widgets provide SafeHtml-aware methods that will automatically handle
your SafeHtml object. The toSafeString(String) method is private for
this reason--to encourage passing around SafeHtml instead of String.

Does an attribute-less  tag do anything? Allowing attributes
certainly makes  and  unsafe, as you point out with the
onclick example.

Creating your own sanitizer may be the way to go for your application,
as the one provided is quite simple (hence the name :) That said, it's
very easy to introduce security holes and I would recommend against
rolling your own. Large apps, for instance Google Wave, have been
written using SafeHtml and without custom sanitizers. (AFAIK)

Another option for you may be the SafeHtmlTemplates. The SafeHtml
guide I linked before gives all the details, and you can see some
additional uses of templates in practice in CellTable.java (and many
of the other Cell-based widgets.)

Example:
@Template("{0}")
SafeHtml div(SafeHtml contents);

Re: Form element values not binding in custom input cell (using AbstractInputCell)

[John LaBanca]

AbstractInputCell is intended to be wrap a single input element, not an
entire form.  Specifically, you need to override getInputElement(parent) to
dig into the DOM and get the input element that you are wrapping.  By
default, getInputElement(parent) gets the first child of the parent,
assuming that the cell renders a single input element and nothing else.
 Still, even if you override getInputElement, you'll only be able to return
one value.

What you really need to do is create a new AbstractEditableCell.  In
onBrowserEvent, catch the change event and dig down to all of the input
elements in the form, updating the DTO as needed.

Thanks,
John LaBanca

NetBeans GWT and JUNIT

[darkling]

I'm trying to debug my Junit test case because its throwing tons of
errors. However when I try to debug it instead of being able to run
it, it tells me

The test class 'com.baa.client.BaseDynamicFormTest' was not found in
module 'com.baa.AccountView'; no compilation unit for that type was
seen

So now rather than debugging the errors that are caused when I run the
test, I'm trying to debug the errors that only appear when I debug the
test!

I've seen lots of posts on this basic topic but they've all been
Eclipse based and I'm not sure how to translate it for Netbeans. I'm
using the GWT netbeans plugin and my test classes live in the test
directory not the src directory.
This is my module file:


http://google-web-toolkit.googlecode.com/svn/tags/2.0.0/distro-
source/core/src/gwt-module.dtd">

  
  
  

  
  
  

  
  
  
  

  
  
  
  
  

   
   
   
   
  
  



I'm trying to include the test sources in the module but I'm not sure
if I did it right. Can anyone help me?
Thanks

Form element values not binding in custom input cell (using AbstractInputCell)

[sevendays]

I have created a CellBrowser where each cell is a custom HTML
component that features a few different HTML form components (e.g.
age, feeling etc.).

The form displays fine, however, I can't get the value entered in the
form into the client-side code. The relevant element in the DOM
doesn't have the 'value' attribute set properly.

I have tried a few things, including:

1) Getting the element from the DOM object using
dom.getElementById(ELEMENT_AGE_ID), this returns an entity but value
is null, even though I had just entered a value into this element.

2) Recursively looping round the DOM node tree, and printing it out to
the console (printElementTree()) - again I can see the element but the
value is null (after entering a value).


What am I not doing correctly? How can I get the value attribute to
update on the element in the DOM? Once it has been updated, how do I
get the values from the elements with IDs ELEMENT_AGE_ID,
ELEMENT_FEELING_ID etc.?

An extract of the code is below. Any suggestions or advice would be
appreciated.

public class NodeTreeItemCell extends AbstractInputCell {

public static final int CELL_WIDTH = 440;

// these statics are the HTML element IDs
public static final String ELEMENT_AGE_ID = "txtAge";

GWT IE 7 Window Resizing Bug

[mayumi]

For a GWT project I am working on, I having trouble fixing a weird IE
7 bug having to do with window resizing.
Basically, when I re-size the window and change the history token(load
the different section of the app) center of the app stops resizing, so
sort of like becoming fixed positioning.

Center of the app is styled with   with  as
child element.
There is no custom styling for this section of the page.
So basically when you re-size the window and re-size it back to full
screen, window does re-sizes but not the app (app is weirdly fixed in
the previously re-sized position)

Does anyone know how to fix this issue?

Thanks

ClassCastException in client deserialization of JPA annotated entities

[cfillol]

I'm using GWT 2.1 in hosted mode.

The following GWT-RPC service that returns JPA annotated objects that
are NOT connected to database, produces a deserialization error in the
client side.

public TipoCable findTestTipoCable() {
TipoCable tp = new TipoCable();
tp.setId((long)1);
tp.setDescrip("Hola");

DesignacionCable dc = new DesignacionCable();
dc.setDescrip("sadfad");
dc.setTipoCable(tp);

tp.getDesignacionCables().add(dc);

return tp;
}

The object returned by the server is serialized with no errors, but
the client produces an error when tries to deserialize it.
If I remove JPA annotations from the entity classes, the
deserialization goes right.
Is this a bug?


I have observed that the the serialized string returned in each case
are slighty different:

The one from JPA annotated objects that produces the deserialization
error:
//OK['B',6,0,0,3,0,1,0,5,4,1,3,2,1,
["es.excentia.esco.data.model.TipoCable/
95382644","Hola","java.util.HashSet/
1594477813","es.excentia.esco.data.model.DesignacionCable/
3990987763","sadfad","java.lang.Long/4227064769"],0,6]

The one from the same objects without JPA annotations, that works ok.
//OK['B',6,-1,0,5,4,1,3,2,1,
["es.excentia.esco.data.model.test.TipoCable/
4254737913","Hola","java.util.HashSet/

1472385747","sadfad","java.lang.Long/4227064769"],0,6]


Here is the error that is generated when deserializing in the client
side.

Hi,
thanks for your reply.
I created an Tomcat 6.20 server but how I can add it to my project? I
remember you that my project is a "GWT Web Application Project"
created with Gwt Plugin for Eclipse.

Can you send me a link of a tutorial?

Thanks very much

gwt website very slooowwww

[cri]

I know this is a little off topic, but has anyone noticed that the gwt
website is very slow the last few days. Hopefully, they know about it
and are working on the fix. Sometimes I have to wait literally minutes
for a gwt forumn search to complete, for example. Also, I just clicked
on a forum article link and it took a few minutes to come up in a page.

Re: To smart GWT or not

[Jaroslav Záruba]

...until you run into some SmartGWT magic - like widgets not working
without otherwise completely useless 'final' (have fun trying figure
that out), newly spanned records not appearing in tree, styles not
getting applied until mouseover, etc.
What looks like polished set of awesome widgets might turn into
nightmare which makes you throwing your deadlines out of the window.

(Like I said before, this particular experience with SmartGWT is one
year old.)

With GWT the start might be slower but you can predict the deadlines +
you're not working with 'black box'.

Re: GWT 2.1 Activities – nesting? YAGNI ? - an exa mple of where you NEED it !

[Brian Reilly]

Looks like I'm going to have to eat my hat on this one:

http://groups.google.com/group/google-web-toolkit-contributors/browse_thread/thread/57cae16478971519

It's a proposal to change Activity from an interface to an abstract class...
basically removing the Activity interface and renaming the existing
AbstractActivity to Activity.

It sounds like there are other breaking changes coming in 2.1.1. I'm curious
to know what they are...

Re: Facing some problems after switching to GWT 2.1 from GWT 2.0.4

[Brian Reilly]

I fiddled with this quite a bit a while back, and I just upgraded to 2.1 so
I panicked when I read this. However, I just tested in Safari and Firefox
(both on Mac) and everything still works.

The key, as Dominic mentioned, is to handle KEY_ENTER in a handler for
KeyDownEvent instead of KeyPressEvent. Actually, I also just noticed that
I'm not using event.getCharCode(). I'm
using event.getNativeEvent().getKeyCode(). In fact, looking at the JavaDoc
for KeyCode, it says, "Contains the native key codes ...", so that gives me
some confidence that getting the key code from the native event is the way
to go.

I suspect that it's the combination of using KeyDownEvent
and event.getNativeEvent().getKeyCode(). Character codes are probably more
to represent printable characters. While you could consider a new line a
printable character, the enter key doesn't translate to a new line in all
input contexts. I suspect you're in one of those contexts (if you're trying
to add some behavior for it), so it makes sense that you want the native
event in this case instead of whatever character it would be interpreted as.

Thanks for the confirmation, Thomas. I felt like it was a bit cumbersome to
use, but it makes more sense as a consistent way to get that behavior in
generated code (which is unfortunate, but it is what it is).

I can think of two approaches, depending on the specificity of the places.

1. Use an activity mapper for the center region but not the east region.
This would be appropriate if the center region shows the item of interest
and the east region contains some contextual detail that isn't worthy of
being encoded into a place.

2. Have both the center and east regions react to the same place where,
unlike option 1, the place contains enough context for both regions. The
east region would use that extra detail to display something specific about
the item of interest while the center region can ignore it if it doesn't
affect what's displayed.

I'm sure there are more ways to approach it. Just keep in mind that activity
mappers are for mapping places to activities. Once you decide how granular
you want your places to be, that will help determine the best use of
activity mappers.

CachingActivityMapper "caches the last activity it returned, to be re-used
if we see the same place twice" (
http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/activity/shared/CachingActivityMapper.html).
If your concern is memory, there should be little to no overhead when using
a CachingActivityMapper. As for performance, the goal of
CachingActivityMapper is to avoid initializing a new activity (and
potentially fetching data from the server, doing client-side processing,
etc.) when the current activity already represents the requested place. I
can't think of any downside to using CachingActivityMapper... as long as the
wrapped activity mapper and the places it uses are implemented as advised
(be sure to properly implement equals() and hashCode() for your places).

Re: Facing some problems after switching to GWT 2.1 from GWT 2.0.4

[aditya sanas]

hi dominic,


I m receiving key press event in all the browser the thing that i have
noticed which doesn't work in GWT 2.1 is -

 *if(event.getCharCode()==KeyCodes.KEY_ENTER){ *

the o/p of event.getCharCode() in GWT 2.1 is nothing not even 0 so i cnt
compare it with KeyCodes.KEY_ENTER

i had tried one more new method that has been introduced in GWT 2.1 which
getUnicodeCode() which gives 0 whenever i presses ENTER but this is not the
right because i m getting 0 even when i m pressing any arrow key.

how to figure this out...?

Re: Facing some problems after switching to GWT 2.1 from GWT 2.0.4

[dominic jansen]

hi aditya,

i ve noticed that there are different behaviours for the
KeyPressHandler for each browser (e.g. for me the safari browser did
not recognize the keypressevent).

maybe you can use the KeyDownHandler or KeyUpHandler instead of the
KeyPressHandler. this worked for me

best, dom

AXIS2 WITH ECLIPSE AND GWT PLUGIN

[bond]

Hi guys,
I've a big problem. I've a gwt project with Eclipse Helios + gwt 2.1
and gwt plugin 3.6. So my project is NOT a web project and when I run
it Eclipse uses Jetty to deploy it.

Now I've to creare some web services with axis 2 in order to publish
them in my project. The web service wizard can't create my service
because it wants a web project with Tomcat.

There is some solutions to my problem?

Thanks very much

Best regards
