Adapting GWT to Adobe air

[lalit]

We are looking to package our application so that it can be run
locally using Adobe air. At the moment if we try to run with the adt
tool of adobe air, it throws security restriction. There are post
around how to circumvent it but none of them is successful(May be I am
still missing some things.) some questions I have got:
- Is anyone able to successfully do that and if there is a tutorial to
follow.
- If we digitally sign the application, will the security restrictions
go away.

thanks,

RPC Problem with HashMap containing ArrayList Value

[richip]

I've an object which contains a HashMap instance. I'm
finding that when I put a value of type ArrayList, RPC calls fail with
a SerializationException that starts with:

com.google.gwt.user.client.rpc.SerializationException
at
com.google.gwt.user.client.rpc.impl.SerializerBase.getTypeHandler(SerializerBase.java:
148)
...

Any ideas why and suggestions on what to do to get to my intended
process?

Re: Help with building GWT from source - javax.validation.ConstraintValidation cannot be resolved

[Tom K.]

   Thanks for the quick reply.

   That seemed to remove a bunch of my errors, but now I'm still left
with errors.  Forgive my ignorance on how Java dependencies work, I
work primarily in C/C++, so I don't work in Eclipse as much as I
should.

   I looked at Maven earlier today for the first time, but I seem so
close to getting it to run now, that I wanted to get it working first
before I attempted to get Maven working.

  What I did was copy gwt-servlet-deps.jar into my project's
directory, and in Eclipse, I added it into the build path for my
project.  It seems that gwt is still using it though, and isn't
finding the reference to it.  Is there an ant setting I need to update
to include it in the gwt package, or did I just not add the dependency
correctly?

Here's my error output when I run:

[luca2010]

I have tried to install GWT,GWT Designer on Eclipse,I placed the
absolute URL for it but instead of http://.,I placed
https://..,at first sight the installation proceeded but I
received the warning : "You are about to install software with

installation is secure?

GWT for Chrome Extension building?

[roschler]

I am a Chrome Extension newbie but a veteran programmer.  My
understanding is that GWT "compiles out" to Javascript and other
elements, not a typical Java JAR or JAR container format.  Does this
mean that the output of a GWT project can be easily integrated into a
Chrome extension?  If yes, is it a good idea or are there too many
hoops to jump through to make it work well?  I'd like to use GWT if I
could and take advantage of it's slick UI and other attributes, but I
don't know if it is a suitable tool for building Chrome extensions.

Thanks,
Robert

Right, that would explain it... I suppose with the Googlers in CC
there's no need for me to file a bug report?

Re: Help with building GWT from source - javax.validation.ConstraintValidation cannot be resolved

[David Chandler]

Hi Tom,

Sounds like you're running an app that uses RequestFactory, which requires
additional 3rd party dependencies on the server. These are available in
gwt-servlet-deps.jar which you'll find in the gwt-0.0.0 dir. You just need
to add it to your classpath.

If you're using Maven, the Expenses sample POM includes these for you.

By the way, the gwt-0.0.0 numbering is correct if you're building from trunk
or the release branch, which hasn't been released yet.

Eclipse Plug-in - Locks up Eclipse

[David E.]

When clicking the "clear log viewer" button in the "Development Mode"
tab in Eclipse when using the GWT plug-in it often completely locks up
Eclipse requiring a hard shutdown and reboot of Eclipse.

Eclipse Version 3.4.2

You should take care of this minor yet annoying issue.

Thanks,

Re: Problem with Gilead Integration in GWT, Spring and JPA

[gperetin]

>From the output above, seems like you're missing @Transactional (or
XML configuration if thats what you're using) on one of your methods
that access database.

However, I would recommend you cheking out MyBatis data mapper (if
that's an option for you), I started using it recently instead of
Hibernate and found it much simpler. You do need to write some SQL
though... With MyBatis you don't have to use Gilead at all since it
returns plain POJOs that can be serialized, unlike Hibernate that
wraps POJOs.

Help with building GWT from source - javax.validation.ConstraintValidation cannot be resolved

[Tom K.]

I've downloaded both the main trunk version as well as the build under
releases/2.3, and both seem to have the same problem.  I can get
everything built OK, and I'm not showing any errors in the output from
the build.  When the build is complete, for some reason it labels the
final packaged build as gwt-0.0.0 (it does this using both the 2.3
release build as well as trunk).  Everything seems to be fine and I
can deploy everything OK, up until I try and access my GWT app.  When
I do, I get pages of errors because the import
javax.validation.ConstraintValidation cannot be resolved.  I've tried
to figure out the numerous build scripts to figure out why this import
isn't included in my jar, but to no avail.  Can anyone help me figure
out what I might be missing?  This is my error log when I run my app:

Re: GWT hosted mode does not work in FF4

[Chris Conroy]

That's not a crash, that's an exception, and it means your deferred binding
for that class isn't set up properly. FF4 should present itself as the
gecko1_8 UA so this should be the same behavior that you see on FF3.6.

Re: Cross domain GWT RPC

JSON or ProxyServlet is for me not an option. I need to transfert a

About the ProxyServlet, the main domain is not mine.

Re: How to define a @ProxyFor(...) for a class without setters

[Christien Lomax]

Well, for the Solr case I mentioned in my example, it'll probably work fine 
then, as FacetField is passed back from Solr... its never written to by the 
clients.

It would be nice to have some sort of annotation that allowed you to define 
an @ProxyForConstructor ;)

Re: How to define a @ProxyFor(...) for a class without setters

[Y2i]

I have a number of value proxies with final fields that are set in 
constructors.  RequestFactory works fine with them, but there is no way to 
create the instances on the client, only on the server.  From the client 
point of view these objects are read-only (which works perfectly with 
projection queries)

Re: Controlling multiple columns sort order in GWT 2.2 CellTable

[Yaakov Chaikin]

Hmm... One idea came to me... Would you just accomplish this by
providing a comparator for the column that drives the 1st order sort
that has custom code to sort the rest of the data at that point? I
guess that should work, right?

Re: Access Service Layer inside RequestFactory EntityLocator

[David Chandler]

You can create your own ServiceLayerDecorator that overrides the default
behavior of the createLocator() method. There's an example of wiring in a
custom ServiceLayerDecorator here:

http://code.google.com/p/listwidget/source/browse/trunk/src/main/java/com/turbomanage/listwidget/server/servlet/

Basically you extend RequestFactoryServlet to add your own decorator, then
rewire web.xml to serve /gwtRequest with your custom servlet.

Your own ServiceLayerDecorator would presumably get the Locator instance
from Spring instead of the default new instance.

How to define a @ProxyFor(...) for a class without setters

[Christien Lomax]

Is there a way to create a Proxy for a class that does not have a setter? * 
(instead 
who's value(s) are set via its constructor)*

e.g.: Solr's 
FacetField
 class.. 
the field I want to proxy is the name.. but the name is set in its 
constructor, not via a setName(...) method.

Cookies in gwt

[khiem nguyen]

hi,
it's possible to have cookies with the same name (with the same gwt-app)
so if i call: Cookies.setCookie("name", "value"), with firebug i  can see
there are many cookies with name="name" is sent.
so it's not consitent if server needs only 1 correct info from cookie. i
think about calling Cookies.removeCookie("name") before setting it. but
1. does it remove ALL cookies with this name the client ?
2. will calling Cookies.getCookieNames() return duplicate names or only
DISTINC ?

i want to be sure there's only 1 cookie with 1 name on the client ? what
would be your suggestion ?

thanx

SafeHtmlUtils on the server side

[Matt]

I am trying to use the SafeHtmlUtils class on the server side to make
sure some HTML I am sending back to the client side is placed in a
SafeHtml object before it is returned. I am assuming it can be used on
the server side as its package name is com.google.gwt.safehtml.shared
and the class is inside of the gwt-servlet.jar When I go and call
SafeHtmlUtils.fromSafeConstant() I get a NoClassDefFoundError (below).

java.lang.NoClassDefFoundError: com/google/gwt/thirdparty/
streamhtmlparser/ParseException
at
com.google.gwt.safehtml.shared.SafeHtmlUtils.fromSafeConstant(SafeHtmlUtils.java:
79)

I found the class/package that it was looking for in the gwt-dev.jar.
I am wondering if this is a bug that should be reported to Google or
is the SafeHtmlUtils class not allowed to be used on the server side?

Thanks.

Re: Is Google WebKit the same entity?

[David Chandler]

In that context, I suspect that Google WebKit is referring to Chrome since
it's based on http://en.wikipedia.org/wiki/WebKit

GWT is unrelated.

Controlling multiple columns sort order in GWT 2.2 CellTable

[Yaakov]

Hi,

At this point, I figured out how to create a multiple column sort. I
create 1 ListHandler and hadd that to the CellTable with the
addColumnSortHandler method. I set each column I want to be sorted
with setSortable(true) and then set multiple Comparators for each of
those columns using the ListHandler.setComparator method.

At the very end, I do this:
cellTable.getColumnSortList().push(column3);
cellTable.getColumnSortList().push(column2);
cellTable.getColumnSortList().push(column1);

This way column1 becomes the primary column to sort by, following by
sorting on column2, and then column3.

The question is this... How is the column sorting order affected when
I click on column2, for example? Obviously, if I do that, column2
becomes the primary sort column, but what is the secondary? column1?

What if I want to make it that when the user clicks on column2, the
column sorting order should be column2, column3, column1? How do I
accomplish that at the same time keeping a regular column sorting
order when the user click on column1 (i.e., column1, column2,
column3)?

Any help would be much appreciated!

Thanks,
Yaakov.

IE developer plugin installation

[Eike Reifhardt]

Hi There,

I'm having trouble getting the plugin to work & hope someone might
have an idea. I'm working on a MacBook and when I open the URL with FF
or Safari, I get promted to install the dev plugin, when it's not
installed. However, when I am open the URL from inside a Virtual
Machine, running XP IE8, I do not get prompted to install anything -
the App just starts blank white with the notice, that the app is
loading.

When I am try to install the plugin manually (downloading the exe), it
is not listed under the add-ons. Registering the dll manually won't
work either. I've also tryed to switch off the internal firewall - no
luck.

I start the App from the Terminal with: mvn -Dgwt.bindAddress=0.0.0.0
war:war gwt:run
So binding the adress should not be the issue.

We're using GWT 2.1.1 and I have no idea how to get the plugin
working.

TIA,
Eike

Re: GWT CellList custom template for Cell Items

[Thomas Broyer]

Override the CellList styles (pass an overridden CellList.Resource to the 
constructor) to add the appropriate CSS properties to cellListEvenItem and 
cellListOddItem.
I'd recommend using display:inline-block instead of float:left though; have 
a look at the com/google/gwt/resources/client/inline-block.css for a 
cross-browser implementation.

  Use ValueListBox instead of ListBox. 


  ValueListBox has methods setValue(T value) and T getValue() and it can be 
used as editor. So you probably won't need your custom ListBox anymore.

GWT 2.2 and FocusWidget

[bconoly]

Hey All,
   I have a custom widget that extends the GWT FocusWidget.  It is
highly dependent on getting onFocus and onBlur events but
unfortunately when I recently upgraded to GWT 2.2 it no longer fires
these events.  Does anyone have any idea what I can do to fix this or
why this is happening?

Re: GWT CellList custom template for Cell Items

Template files are built using GWT.create, so you always have the option of 
extending the interface and then changing your [app].gwt.xml file to rebind 
CellList.Template to MyNewCellListTemplate.

For more info on deferred binding you can check this out.

GWT CellList custom template for Cell Items

[Zed]

By default CellList items rendered as column. I want to add float:Left
style to each item. I want them to display as a row. But every my
element in CellList is wrapped by CellList . So I want to
customize that div style template. Is it possible?
I found in CellList.class sources interface :

 interface Template extends SafeHtmlTemplates {
@Template("{2}")
SafeHtml div(int idx, String classes, SafeHtml cellContents);

@Template("{3}")
SafeHtml divFocusable(int idx, String classes, int tabIndex,
SafeHtml cellContents);

@Template("{4}")
SafeHtml divFocusableWithKey(int idx, String classes, int
tabIndex, char accessKey, SafeHtml cellContents);
  }

Can I customize that? Or maybe there is another workaround way?

load(String code,final Runnable onLoad)

Re: When is an object passed over RPC safe to modify?

[Martin Larsson]

I need the status on the server (new, deleted, modified), so I must wait 
with the modification until I know the objects have been serialized. 
Even though Javascript is single threaded, the actual RPC-call is done 
with a separate XMLHttpRequest-object, I'm uncertain if the objects are 
safe on the code line right after the actual RPC-call. The easiest (at 
least for me, but probably also Google) would be if they were. But how 
would I know?


On 25. mars 2011 03:26, Craig Mitchell wrote:

Javascript is single threaded, so you can just mark them as clean just
before you send them.  IOW.  It won't be possible for them to be
updated between when they are marked as clean, and when the call to

If the save fails, just mark them back to being modified.

Note: During the save process on the server, they can be modified.

We're experimenting with background saving in our GWT-app. IOW. we
mark objects as 'modified', and then at regular intervals, find all
modified objects and pass them to the database for storage. The
question is when is it safe to mark the object as 'clean'. The on-
success-handler of the save()-method is too late, obviously. That can
happen any time later and the user might have modified the object(s)
again. As the status also can be 'new' or 'deleted', I need to pass
the status to the server so it knows what to do. IOW. I can't mark the
object clean too early. What I'd like is to mark them 'clean' when
they're safely serialized, and have the on-failure-handler set them
back to 'modified' if the save() failed.

So ... is there any point in the code where I can be certain that the
objects are serialized and on their way to the server so I can start
modifying them in the client without interfering?

Figure 4 here:http://eclipse.dzone.com/news/making-gwt-remote-procedure-ca
indicates that the objects are safe once the method in *Async returns.
Is that safe?

Re: ProxyAutoBean server-side cache

[Thomas Broyer]

[Cc: BobV, rjrjr]

That would explain why our test server regularly becomes unresponsive and 
needs a restart (we shipped our first milestone on Monday for our customer 
to start testing it; I don't think they complained yet, fortunately; it 
hadn't beat us earlier as we test on our CI server which is rebuilt and 
restarted at least once a day)

Looking at the code, ProxyAutoBean's createShim creates a reference cycle 
(the shim references the proxyAutoBean, which keeps a reference on the 
shim). Because the value in the WeakMapping is kept with a strong reference, 
there's always a strong reference to key as well, so the cleanup() never has 
anything to clean.

RequestContext method with enumeration parameter

[Lazo Apostolovski]

Hi there,

I use gwt request factory to load some object from server. I'll give an 
example code:

https://gist.github.com/886743

This code works just fine in GWT Hosted mode. But problem appears when I 
compile GWT code to JavaScript. For some reason, FooState enumeration can't 
be serialized. Java script throws:
Uncaught java.lang.UnsupportedOperationException: 
com.google.gwt.core.client.JavaScriptObject$
And request factory does not send anything to the server. This bug appears 
only when I give enumeration as parameter in RequestContext method, in 
compiled JavaScript code. In hosted mode I dont have any problems with this.

Celltable renderer object

[Marco Gadaleta]

Hello everyone,
is there a way to obtain the object that cellTable has rendering during the
rendering?

For example i've associated a list of object as  dataprovider to celltable
and i want to know what is the object
that celltable has rendering in that time?
This is useful to me becouse i can add or not dinamically another column
based on a specific value of the object

Is Google WebKit the same entity?

[roschler]

I'm just getting started writing extensions for Chrome 11 beta, which
has support for the HTML5 Speech API.  While studying some online
reference docs related to writing Chrome extensions I saw a note
saying that you have access to any of the APIs belonging to "Google
WebKit".  Is "Google WebKit" the same entity as "Google Web Toolkit",
or is it a completely different animal?

Hi Paul,


I think that helps a lot. I initially thought about something similar,
but was not sure if it's the best idea. It involves a lot of overhead
imho. But - it's better than all other possibilities I can think of
now...

Thanks :)

gwt + spring + maven

Hi,

We are going to develop a new project and i want to make some proof of
concept. We want to use gwt, spring and maven. Are these well integrated?
Could we use dev mode with spring?
Did someone tried this GWT designer and is it generating only java code or
ui binder xml based code? Our UI will be very customized with styles, images
etc.. so is gwt designer good for that?
We are seeking fast and effective development. If you could point me to some
good examples, tutorials, blogs etc.

Thanks.

Re: Scroll to content

[Jens]

Maybe searchResultPanel.getElement().scrollIntoView() might help. 

If not you can still play around with ScrollPanel.setScrollPosition(int

I think position should be the value of yourFormPanel.getOffsetHeight()

Re: RPC Serializable = invalid objects graph?

Scroll to content

[Stephan T]

I have a rather large form which is taller than the visible area in
the page. The users enters search criterias in this form and when the
user executes the search I present the searchresults below the form.
because the form takes up the whole screen the user doesn't notice
that the searchresults have been displayed further down below. I want
to programatically scroll the page to display search results. Just
like html anchor works. But I can't use anchors sinxce it interferes
with gwt history management. How do I programatically make the page
scroll to a certain content?

GWT, Ads and Friendly IFrames

[Raphael André Bauer]

Hi,


people that write Ads seem to love the usage of document writes. That
is not 100% compatible with AJAX aka GWT and - in many cases -
potentially breaks the app. One nice solution imho might be the use of
Friendly IFrames (1). The benefit would be that people could continue
writing their Ads in the "traditional" way. But they will not break
the GWT client (Adsense did something not 100% similar this week (with
the intention to speed up things) (2)).

Is there any ready-to-use GWT solution available that encapsulates Ads
in IFrames? Maybe even allowing us to exchange Ads on demand when
"Places" in GWT change?


Just curious,


Thanks,

Raphael

Editor compatible widget

[Metronome & Basic]

As my question got no reply last week ( weekend maybe ) I dare to post it 
once more ?!

The question may be trivial but..

What makes a Widget compatible with Editors

I tried to make a Wiget  that is a modified ( expended ) LisBox
with  setText and getText method , thinking they could be used by the Editor
to set and the String

but it dosn't work

what 's missing ?

The "code"
===
public class Lb extends ListBox {


   List tks = Arrays.asList("X","Z","N","M","D");


   public Lb () {

   for (String s : tks) {

   addItem(s);

   }

   }


   public void setText (String tk) {

   for (Integer x = 0 ; x < tks.size(); x++) {

   if (tks.get(x).equals(tk)) {

   setSelectedIndex(x);

   break;

   }

   }

   }

   public String getText() {

   return getItemText(getSelectedIndex());

   }

}
