InlineLabel doesn't display a subsequent blank space in IE (but does otherwise.)

[dindeman]

The following simple structure in UiBinder produces different results
in IE than in other browsers:

 world!

When debugging the bound widget I find
in IE:
HTML: Helloworld!
Display: Helloworld!

in Firefox:
HTML: Hello world!
Display: Hello world!

Is this a bug? If yes, any workarounds?

Cheers.
Luc.

Re: CellTree question about varying cell composition

[tomInNewEngland]

Is there a way to persuade people to answer questions here?  Or even
to suggest possibilities?  Searching allows me to find lots of
questions like this about CellTree, but I can't find any answers.
Help?  Someone?

Thank you.

"mouseover" is fired twice within the scope of the same cell

[Christian Goudreau]

Here's a little snippet of the code:

if ("click".equals(event.getType())) {
  onEnterKeyDown(context, parent, value, event, valueUpdater);
} else if ("mouseover".equals(event.getType())) {
  onMouseOver(context.getIndex(), event);
} else if ("mouseout".equals(event.getType())) {
  onMouseOut(context.getIndex(), event);
}

Well, when I first enter the cell with my mouse, onMouseOver is called, then
when I move inside the same cell and mouse over  the texte, onmouseover is
called a second time.

Someone have an idea how to fix this ?

HTML 5 Audio onComplete Listener

[stymie]

I am using the new features of the HTML 5 audio available in gwt 2.2.

Is there any way for an onComplete Listener for the audio.Right now I
am using a timer and checking if the currentTime >= to the duration
and then firing my own "complete" listener.

I thought there should be something built in for this.


Thanks

Re: gwt autocompile ;)

> I have no idea what an 'adm' is.
"adm" = administrator

Organization is whom buy my software..

No
For example: In google contacts, when you edit a contact, you can add
fields to the form...
But you cannot add business rules for the field that you added...
I would like allow the "adm" modify the application, adding fields,
business rules, etc...

Is the final product.
The organization that buy my software won't edit the real source
code...
I would like to offers to the client the possibility of customize my
software according to your needs


> Is this an actual question or some kind of elaborate troll?
For example in JavaScript I can write the code, save on database,
return for the application and run the same code, and will work...
But in GWT I need compile all my application again...




The manner on that GWT was designed, this isn't possible...
I would like to discuss one manner to do this... GWT is the best tool
for develop web applications, on my oppinion..


is now more clear?

Re: How do I apply styles??? Strange lack of expected behaviour...

[Jeff Larsen]

you're going to need to make those styles marked as @External or @NotStrict 
on the CssResource inside the client bundle. 

Then you also have to do ClientBundle#CssResource()#ensureInjected() 
somewhere that is guaranteed to be called before you need it, to actually 
have those styles injected into your webpage.

How do I apply styles??? Strange lack of expected behaviour...

[Terry Bachard]

Hi,

I have a CSS file and CssResource.

I define styles like .gwt-DatePicker, or .dateBoxPopup, in my CSS file,
which I can see are applied to the GWT compeonents, but they are never used.

I am adding the styles to my CssResource file, for example:

String datePicker();

String dateBoxPopup();

@ClassName("gwt-DatePicker")
String gwtDatePicker();

I am not referencing them anywhere lese in code, but I should not have to. I
cannot figure this out. I was using the standard theme and thought that it
may have been the cause, but to narow the problem down I am now not using
ANY theme so it's not standard.css taking precedence.

Help in understanding this greatly appreciated!

Terra

How can I intercept various event on cells ?

[Thierry]

Hi !

I'm still attempting to extend the cells standard behaviour, like I
used to do in Swing years ago. Maybe the similarities are decepting ?

I tried overiding the onBrowserEvent on a TextColumn. Nothing fired
I tried overiding the onBrowserEvent on a Cell in a Column : no better
result.

What is the standard way to extend the behaviour of cell components ?

Thanks !

Re: why IsWidget is interface?

[Jens]

To decouple actual widget implementations so we can provide fake widgets to 
methods during testing. Its primary use case is not to be a marker interface 
for widgets.

JavaDoc of IsWidget:

*Extended by view interfaces that are likely to be implemented by Widgets. 
Provides access to that widget, if it exists, without compromising the 
ability to provide a mock view instance in JRE unit tests.*
*
*
*
*
If you do not have the ability to provide a mock/fake view instance during 
testing then you have to use a slow GWTTestCase instead of a fast JRE JUnit 
TestCase.

Eclipse Plugin 2.2.1, GWT 1.5.2, Wont Run

[aisling]

Hi all

New installation of Open Suse 11.3 with Eclipse Version: Helios
Release Build id: 20100617-1415.

I installed the GWT plugin manually from a downloaded zip
(com.google.gdt.eclipse.suite.e36.update.site_2.2.1.v201103311225.zip).

The new plugin works fine with GWT 2.1 which we use for our new
prejects. However I have one project written using GWT 1.5.2. I have
check that the project's Google properties uses the correct SDK (gwt-
linux-1.5.2).

If I right-click and attempt to run the project as Web Application, I
get the following error in the Eclipse console:

Unknown argument: -remoteUI
Google Web Toolkit 1.5.2
GWTShell [-port port-number | "auto"] [-noserver] [-whitelist
whitelist-string] [-blacklist blacklist-string] [-logLevel level] [-
gen dir] [-out dir] [-style style] [-ea] [url]

where
  -port   Runs an embedded Tomcat instance on the specified port
(defaults to )
  -noserver   Prevents the embedded Tomcat server from running, even
if a port is specified
  -whitelist  Allows the user to browse URLs that match the specified
regexes (comma or space separated)
  -blacklist  Prevents the user browsing URLs that match the specified
regexes (comma or space separated)
  -logLevel   The level of logging detail: ERROR, WARN, INFO, TRACE,
DEBUG, SPAM, or ALL
  -genThe directory into which generated files will be written
for review
  -outThe directory to write output files into (defaults to
current)
  -style  Script output style: OBF[USCATED], PRETTY, or DETAILED
(defaults to OBF)
  -ea Debugging: causes the compiled output to check assert
statements.
and
  url Automatically launches the specified URL

Any ideas how I can get the GWT 1.5.2 project to run with the Eclipse
plugin 2.2.1 or do I have to use an older version of the plugin and
where can I download it from please?

Thanks very much
Aisling

Automatic browser language detection

[stintorero]

Hi,

I am using GWT 2.2.0 and firefox 4.0. I would like my web app detect
automatically the client property "locale" from Edit > Preferences >
Languages.

I have seem some solutions in GWT 2.3.0-M1 using  in the .gwt.xml file, but
this detects the language of the browser not the language choose by
the user into Preferences.

Somebody know what should I do?

Thanks in advance. Regards.

Sebastian.

CellTable : can't do both Selection and Edit on lines ?

[Thierry]

Hi !

I'm using GWT 2.2.
I tried to have a celltable where I can both select lines and modify
them.
I added a SingleSectionModel to the celltable. It works. But as soon
as I click on a DatePickerCell on any line, the selection stops
working.

To check if I did something wrong, I executed the
CellTableFieldUpdaterExample from GWT documentation.
I just added a SingleSelectionModel to the contact table.
The selection mechanism breaks as soon as I click on the
DatePickerCell that modifies Contact birthdate on the example.

Maybee it's not possible to do both selection and edit on lines ?

What I was trying to achieve is to display statistics on the 'clicked'
line on another panel. And allow the user to edit the line on the
celltable. I didn't want the user to click on a icon / button on the
line, but just select the line.

Is there another way to achieve this ? Any way to intercept a 'user
clicked on a line' event on the celltable ?

Thanks for your help

Re: RPC in onWindowClosing() problem

[George Georgovassilis]

Hello Ania,

This might be a browser related behavior - if the window is closed,
all activities related with it are cancelled.
It might be best if you tried an alternative aproach: instead of
having the browser explicitly signing the user out of your application
(which is what you are trying to implement by handling
onWindowClosing), you might want to implement a keep alive mechanism.
The browser would notify the server every X seconds, which counts as a
logged in user. If the last notification is older than Y > X seconds,
your server may assume that the user logged out or just closed the
window.

Re: GWT 2.2 CellTable dragging column widths with mouse ...

[Musicman75]

I don't want to render 10 rows, that's why I use the celltable and
it's paging functionality.
To handle the whole datatable on client side (sorting, filtering, ..)
without server calls every time.

CellTable can handle a big amount of data, the only thing I miss is
column resizing on mouse dragging.

GXT, SmartGWT look nice, but the datastructure needed to fit with this
framework isn't useful for me and I don't want to use third party
libraries in my project.

gwt autocompile ;)

[Diego Lovison]

hello,

I would like to develop an application that the "adm" of the system
can modify the view, add rules, buttons, fields, and others

ok I can create something like google contacts, when you can add
fields to edit...
but in google contacts I cannot edit the source code...
for example:
*client1: validate for this field
*client2: validate for this other fields...
*client3: get the list of my database

keep 3 source code for 3 client is easy, but if I have 5000 clients...
is very difficult..

gwt problem:
I can create "dynamic code" using javascript when I write and run...
in gwt I need write, compile and so will run...

gwt solution:
gwt in my opinion is the best framework for web app, and I would like
to use it for this project...

any ideias?
someone understood what I told? lol

regards
Diego Lovison

Cell widgets selection and EventTranslators

[Javier]

I want to select a cell on mouse down event instead of click. This is
how selection works in windows explorer (among others) and is very
useful if for instance you want to start a drag operation inmediatelly
after the mouse down.

Creating a custom EventTranslator is great as it allows me to select
the action to perform depending on the event type. However when doing
multiple selection the action I return is ignored unless it is a click
event. Said with different words, the DefaultSelectionEventManager
only takes into consideration the Action returned by the translator if
the event is a click event.

IMO the correct behaviour would be that the EventManager performs the
action returned by the translator no matter the event type. In fact
this is the behaviour for a single-selection model but not for a multi-
selection model.

A'm I missing something? Many thanks.

Re: Is validation on client side enough or do I need both?

Server validation is allways a good thing  no matter which scenario. Dont
trust what s coming from the client.

Is validation on client side enough or do I need both?

[Stephan T]

The scenario:
I have a form where you can create a new person by entering name in a
textbox and click a button. When the user clicks the button I grab the
value from the textbox and sets it on the Person object. The Person
object validates the value and makes sure the name on the object only
contains a-z. If not execution stops and an error is presented to the
user. If all is good I send the Person object via an RPC call to the
server.

The question:
When continuing execution on the server, can I be sure that the name
only contains a-z or do I have to do server validation as well for
protection from attackers?

Am I over using layout panels?

[Terry Bachard]

Hi,

The GWT docs specify thet the layout panels should be used to define overall
application layout; but when looking at the mail example, there's
DockLayoutPanels within DockLayoutPanels , etc. Personally, on my project, I
have DockLayoutPanels (or SplitLayoutPanels) embedded 5 or 6 deep in some
places. They define the overall layout, the layouts without layouts, and
even layouts within those layouts...(i.e., 'centers' contain other layour
panels, of which themselves have centers which contain layout
panels,...etc.)

It does the job for me...but I wonder about performance issues or changes in
the future? Is this bad practise?




Regards,
Terra

RequestFactory Hibernate One to many mapping datatype

[mfiandesio]

Hi to all,

I am trying to retrieve an object with Hibernate User which has a one-
to-many relationship with a Role object.

This is mapped as a Collection roles but requestfactory
validation complains if the proxy interface has the method
Collection getRoles as the data type is not Set nor List.

If i change the UserProxy method to Set getRoles it
complains that in the User object does not exists a matching datatype
method.

All the hibernate mapped entity are in a jar that we use across
various applications and it would be quite painful to change all the
Collection to a Set or a List.

Is there any way to change the validation beahviour?

Thanks a lot,
Matteo

I'm using CodeBox for Mac (available in Mac App Store). Because it has 
code formatting and it does not "shrink" your sample sometimes, like 
Evernote.

RequestFactory, Hibernate and versioned data

[Bappy]

Hi there,

Since going from 2.1 to 2.2 RequestFactory has stopped transferring my
Hibernate generated objects back to the client. The first error was
this:

com.google.gwt.requestfactory.server.UnexpectedException: The domain
type Foo_$$_javassist_45 cannot be sent to the client

I managed to fix this using a custom decorator, however now I get the
following error:

com.google.gwt.requestfactory.server.UnexpectedException: The
persisted entity with id 1 has a null version

As I don't use versioned data I'm not sure what to do to fix this, I
just set the version to "1" before returning it and it works although
this is a bit contrived! Do I need to get Hibernate to put a dummy
version on it even if I don't use versioned data?

Clearly now RequestFactory needs a non-null version, is there any way
I can change this behaviour?

Cheers,

Bappy

Re: GWT 2.2 CellTable dragging column widths with mouse ...

[Musicman75]

@Sky
Nice idea to include resizing on mouse dragging.

Any implementation available?
I checked out the ScrollTable from incubator, but it's too slow
(rendering with more than 10 rows is impossible).

The resizing functionallity from the Scrolltable implemented together
with CellTable would be a great thing.

Thanks
Stephan
