Great idea Joe,

I was missing something like this for a long time. But the
categorization is little bit confusing me.
What is the difference between Libraries and Frameworks, or Tools.
Wouldn't it be better to cover some specific domains in the
categories? Like UI widgets, RPC, security, MVP, etc ?

Thank you again.

Popup Panel that follows the page

2010-07-26 Thread Michael

Hi,

In my app I have a calendar.  When you click on the date I have a pop
up panel that popups on the date that shows different options (add
birthday, add appt, etc).  How I have it right now the pop up shows
where it should if the scroll bar is at the top.  But if you scroll
down the pop up does not show up in the right place.  It seems the
popup panel is attached to a particular place on the screen not a
particular place in the panels.  Is there a good way to anchor the pop
up panel to a particular widget?  Is there a better way of doing this?

An example of what I would ideally want is the popup (for contact
info) in gmail when you hover over a person in the chat panel on the
left.  It always pops up next to the user name that you hovered over.
I would also like it to go away if you move the mouse away (instead of
click like a popup) but I could do without that.

Thanks for the help,
Michael Herman

Re: New Project Start up in GWT 2.0

If you want to use UIBinder, then you will have problems with 3rd
party component libraries.
No component library has official support for UIBinder (ExtGWT,
SmartGWT, ...), but smartGWT has one project which solves this, but it
is not an official one (http://code.google.com/p/uibinding-smartgwt/).

So, if you want to use UIBinder just go with core GWT widgets with
custom CSS styles.
MVP is very good practice, but the best practices are changing from
year to year :). Google guys are implementing in this time the Actions
(ActionManager) pattern using RequestFactory ... and everything will
be managable/generated by Spring Roo.

I'm the old school ... i'm still using MVP with GIN and event bus, but
the choise is yours.

Re: Class implements IsSerializable does not show up in all RPCRequest.serializationPolicy

Maybe the code snippet will helps.

Do you have default constructor for serialization purposes?
Is your custom exception listed in service method definition?

Peter

On 24. Júl, 17:34 h., citress citr...@gmail.com wrote:
 Hi,

 GWT version: 2.0.0

 My understanding of the serialization policy is that if a Class
 implements IsSerializable, it will be part of GWT's serialization
 policy whitelist. I created a custom, runtime  exception that
 implements IsSerializable. This runtime exception shows up in the
 serialization policy of one RPCRequest method, but not in another.
 Both methods do not declare the exception in their method
 declarations.

 Why can this exception be serialized in one RPC method call but not in
 another? Is implementing the IsSerializable interface alone not enough
 to make the class part of the serialization policy?

Re: Another Ajax Crawling question, is #! acceptable rather then just #! ?

2010-07-26 Thread Katharina Probst

Sorry, I'm a little confused too.

When googlebot sees www.example.com?mykey=myvalue#!myhistorytoken ,

it'll turn it into

www.example.com?mykey=myvalue_escaped_fragment_=myhistorytoken .

Can you give an example (complete fake URLs, like I did above) to illustrate
the problem you're seeing? That would be helpful.

Thanks,
kathrin

Short answer is I don't think you should use #!.

On Sat, Jul 24, 2010 at 12:27 PM, darkflame darkfl...@gmail.com wrote:

Thanks, Sorry if its not clear, but I am actually talking about all of
those things.

PHP is my back end which is generating the static pages.
GWT is what my site is coded in. Its completely dynamic and makes
extensive use of # tokens to store and retrieve its states.

I'm attempting to get my side Ajax crawl-able using this guide;
http://code.google.com/web/ajaxcrawling/docs/getting-started.html

This guide states to replace the normal #anything style history
tokens with #!anything tokens instead. Note the additional !
When google's crawler is requesting these pages it swaps the #! for
?_escapedfragment_=, allowing the server to generate a static page
using the query string.
This is all laid out in googles guide.

However, the formating of this ?_escapedfragment_= does not allow
php to process the key/value pairs in the query string as it normally
could.
PHP can normally read of key value pairs from the query string using
its $_GET[] command. However, under this system ?_escapedfragment_=
in the url requested prevents the first key value pair being read.
(as the parser now sees _escapedfragment_ as its own key, and the
first true key as its *value*).

Thus, in order to use PHP with Google's system for making Ajax
crawlable, I was querying if GWT user's should add to their new
history token format, rather then just !. So the new tokens become
#! rather then just #!.

This is a little confusing, but I think it should be understandable
for anyone who knows both PHP as well as GWT. (or at least, has used
extensive historytokens/states in their web design).

Finally, I mentioned the Webmaster tools Fetch as Googlebot as thats
what I'm using to test if my site is indeed browse-able by google's
bot. Its not yet possible to use it to test completely for this sort
of functionality, however. So some of this work is a little blind.

$_GET['DisplayReview'] returns as empty if the url is, say, ?
_escaped_fragment_=DisplayReview=123

If, however, I use #! on my Javascript, then google will instead
call;

_escaped_fragment_= and $_GET['DisplayReview'] returns the
correct value.

Is this acceptable? Should this be standard practice for those using
php to generate the static pages?

The alternative seems to be manually parsing the whole query string
rather then using $_GET[], but that seems rather messy.

Note; I'm making some assumptions about how google replaces the #!,
as the Fetch as Robot utility doesn't seem to do it yet.

Re: Popup Panel that follows the page

2010-07-26 Thread Tanguy Le Barzic

Hi Michael,

Concerning the location of your popup (extending PopupPanel) on the screen,
you can specify the position by using setPopupPosition. You can then place
it whenever you want, relatively to the browser window (like the example
given in the javadoc for PopupPanel), but also relatively to the element
that caused the popup to appear (see for example
http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/mail/src/com/google/gwt/sample/mail/client/Contacts.java
in
the Mail example, very to similar to gmail).

Never needed to hide it when you move the mouse away, but I guess you could
register a MouseOutHandler to your popup and hide it then.

Setting up a maven based gwt project without using gwt-maven-plugin

2010-07-26 Thread Ivan Yosifov

Hi all,

The following is a little scheme I came up with for configuring a
maven based gwt project. I specifically wanted to avoid using gwt-
maven-plugin as I've had some issues with it. It feels a bit redundant
too.

The example pom below is for an experimentation project that uses gwt,
the incubator and commons-io. The project layout uses the maven
standard /src/main/webapp for the exploded war and not /war as
google's gwt eclipse plugin does. To achieve this maven is configured
to output class files in /src/main/webapp/WEB-INF/classes and not
under /target. The clean plugin is also pointed to same output
locations so that mvn clean works.

The pom defines two profiles. One is the dev profile ( active by
default ) which also depends on the gwt-dev artifact for dev mode,
etc. The second is the web profile which is used for running the gwt
compiler ( for example by calling mvn -Pweb install ). The web profile
uses maven-antrun-plugin and ant's java task to run the gwt compiler.
A trivial bit of javascript is used to determine the processor count
on the current machine and so it's possible to pass the optimal -
localWorkers setting to the gwt compiler.

An ide launch configuration for dev mode would need to:
* use com.google.gwt.dev.DevMode as main class
* add src/main/java and src/main/resources to the classpath
* add something like -
agentlib:jdwp=transport=dt_socket,address=1025,server=y,suspend=n to
the VM args to allow connecting a debugger to the web app
* use something like this for the main class's arguments:
-war src/main/webapp
-startupUrl /index.html
-codeServerPort 1026
-port 1027
com.example.TestGWT.TestGWT

If setting this up in, say, eclipse feels like too much clicking, it's
possible to achieve the same effect from a linux shell by:

running once:

cp=`mvn dependency:build-classpath | grep -E '^[^[]'`;

running every time you want to start dev mode:

ava -agentlib:jdwp=transport=dt_socket,address=1025,server=y,suspend=n
-Xms256m -Xmx512m -Xss50M -XX:PermSize=128m -XX:MaxPermSize=192m -cp
$cp:src/main/java:src/main/resources com.google.gwt.dev.DevMode -war
src/main/webapp -startupUrl /index.html -codeServerPort 1026 -port
1027 com.example.TestGWT.TestGWT

Re: First GWT question: DockLayoutPanel and presenter/views

from the blog about mvp (
http://code.google.com/webtoolkit/articles/mvp-architecture.html), which

Hello,

I've been investigating GWT recently and want to start writing with
it. This is my first question on here, so pardon my ignorance.

I had just got my head around presenters and views. I then tried out
the Mail application that ships with 2.0.4 Eclipse plugin and this
looks really good. Looking at the source code though, I cannot see any
presenters or views and wonder if when using DockLayoutPanel (as the
Mail application does), would one also use presenters and views? If
so, how would they be used with the DockLayoutPanel? What portion of
the DockViewPanel would a view represent?

Thanks,

Pete

Re: subversive checkout as

Make sure you have all the Eclipse files in Subversion. The Eclipse files
(.project, .setup, .launch) are filtered out from the Project Explorer view.

You shouldn't have to create a 2nd workspace. The advantage of a 2nd
workspace is that you can easily dispose of it and start over.

GWT project, but they may have been resolved with a recent GPE version.

Re: HTML5 Offline GWT APP

2010-07-26 Thread Arthur Kalmenson

Yeah, that's definitely possible to do. You need to use a Linker to
build the manifest at the end. There was a Linkers talk at Google I/O
that discussed building an HTML 5 manifest Linker:
http://code.google.com/events/io/2010/sessions/gwt-linkers-webworkers-extensions.html.
You could also pull it out of the Speed Tracer source.

Google Web Toolkit JavaScript Vs hand Crafted JavaScript benchmark

2010-07-26 Thread Ciarán

Hey everyone I am really interested in GWT for a project I am working
at the moement. The main benefit for me is the fact that I don't have
to write JavaScript which I really dislike, but then I was thinking
would the code produced by GWT be slower then hand crafted JavaScript
so I ran a benchmark, the results of which I posted here http://bit.ly/cxo4dS
some very interesting results when running it on the iphone.

GWT service to manage your wine cellar on line

2010-07-26 Thread Danny Goovaerts

You are kindly invited to try out a new GWT based service that I am
launching.

www.cellamea.eu

With this service, you can manage the inventory of your wine cellar on
line. The database with wines does not
contain much data yet, but I hope that this will change as the service
gets used more.

Some more technical information about the service in general and the
use of GWT in particular.

1. MVP
The client side follows the MVP pattern (though not using a general
eventbus).

Model : Value objects  carry the attributes of the domain objects. The
value objects are defined
in XML schemas (with some restrictions, but supporting the majority of
data types defined in XML schemas, XML schema includes and extends).
The java implementation is generated using an XSLT transformation
(similar to JAXB).
The interface of the value objects have the following methods:
* getters
* setters : using basic types or using String.
* adders : for repeating members
* validate : XML schema facets can be used to define syntax validation
rules for the value objects (min lengths, max lengths, min occurs,
max occurs, min value, max value, total digits, fractional digits).
Java code is generated that verifies these rules and throws an
exception with a identification of which fields have which errors.
* toXML : marshalling into XML
This implementation can be used on client and server side.
Unmarshallers are also generated to instantiate a  value object,
starting from the XML representation.
Unmarshallers for client and server are generated(GWT has its own XML
parser and DOM interface definition, hence the unmarshallers cannot be
identical)
The model is  locale insensitive, i.e. it uses standard
representations for date, time, numbers,...

Presenter : the presenter is implemented in two parts
- ServiceController : responsibilities
*interact with server,
*retrieve value objects from the view and set value objects in the
view.
- InteractionController : responsibilities
* translate events from the view into method calls on the
ServiceController
* steer the page flow in the view, based on events received from
the ServiceController (e.g. show the correct view, display exceptions,
  display or hide overlays to simulate a synchronous
interaction,...).
This split allows to reuse InteractionController for common
interaction patterns (for example search, list, detail page
sequences).

View : The view is also made up of several classes
- Application views : these are traditional windows, for example for
search criteria, entry screens, list screen with search results, etc.
  The application views are responsible for the locale manipulations.
- Glue classes (sorry for this rather high level name, I could not
come up with something better) : starting point to put everything
together
   * create presenter classes and application views and glue
everything together
   * show correct application view on request of the
InteractionController
These glue classes lend themselves very well to code splitting as they
are the entry point to the instantiation of the Presenter classes
and the Application views.

2. Deployment
Static files and java script are deployed on an Apache 2 server. This
allows to do some URL rewriting, for example to add locale in the
query string.
Server side follows the SOA principles, (authentication service,
reference data service, static data service, cellar management
service, inquiry service,...).
Each service provides several commands (e.g. createCellar,
applyDelivery, ...) The services are deployed as servlets on Tomcat
5.5.
Database is MySQL. Development and testing is done on Windows,
production deployment on a virtual Linux server.
RPC uses the GWT RPC implementation but very restricted, i.e. all
service calls have a signature of the following type:
String serviceCommand(String requestXML) throws ServiceException
(where serviceCommand is of course the actual name of the command).

The strings are XML representations of request and reply objects.
These are defined and generated using the same mechanism as the value
objects from the model.
Marshalling into XML and unmarshalling from XML are straightforward
calls of the generated methods.
So I only use the scaffolding of the GWT servlet and the handling of
exceptions, not the GWT serialization of the paramaters.

The site is only accessible over SSL to assure the confidentiality of
the data. Cache-control header is set to public for the cacheable js
files
to incite the browsers to cache them (works on Chrome, IE8 and FF3)

3. Authentication
Support for OpenID in general withs specific flavours for using your
Google or Yahoo mail account. Also support for email address and
password. You can use
multiple authentication mechanisms for the same user.

4. Localisation
The service is available in English, Dutch and French. You can define
application level codes as XML schema enumerations and use these types
in your
ValueObjects. These

Writing a JS library in GWT?

2010-07-26 Thread S Rabin

I've done quite a bit of searching to find any information about this,
but it seems that people are more concerned with writing GWT libraries
to keep in GWT before compilation.

I would like to write the libraries I frequently use in my projects in
GWT, then compile and expose them to hand-written Javascript.  I have
several issues with the way GWT seems to handle what I want to do:

1) Bootstrapping.  I understand that the iframe loading method is
highly efficient for large codebases so as to make the page non-
blocking, but for a small library bootstrapping is overkill.  To test,
I tried writing my TableGenerator library (a 7kb handwritten non-
minified library) in GWT.  The result was a 6 kb deferred binding
loader file (table.nocache.js) and 4 permutations of compiled JS
weighing in at 20-30kb each.  Which brings me to issue #2

2) For compiling the code, GWT seems to produce LARGER codebases.
Fast, yes, but how does 3-5kb of source result in 20-30kb of compiled
javascript? Is there a way to crop out all the unnecessary cruft GWT
seems to think I need?

3) I would prefer to not have a bootloader - I anticipate the compiled
form of my code is going to be smaller than the bootstrap code and
would rather it just be loaded.  Is there a compilation option to
disable permutations and output (obviously more to handle different
implementations) code that works in all browsers?

Sincerely,
Scott Rabin

Re: First GWT question: DockLayoutPanel and presenter/views

2010-07-26 Thread PeteUK

Hi Tanguy,

Thanks for the reply. I had read the blog link you posted (and part
II).

In the Contact application, the *entire* application area is initially
taken up with the contacts list. When a contact is chosen for editing
(or the Add button pressed), the *entire* area is replaced by the edit
contact view.

I see the DockLayoutPanel as being different to this. Let's assume the
Mail application was to be changed to be a bit more Outlook like. The
change being a calendar option that could be chosen from the left hand
side (where Mailboxes, Tasks, and Contacts are). When that calendar is
chosen, you don't want the entire application area to be replaced,
you'd just want the two split windows in the centre area to be
replaced by a big calendar.

I am wondering how that would be orchestrated within the application?
Would MVP be used here, and if so, how?

Thanks,

Pete

Re: First GWT question: DockLayoutPanel and presenter/views

2010-07-26 Thread dane.molotok

I have done exactly that for an application. There's no reason you
cannot have a view, with a corresponding presenter, that contains two
views that have their own presenters. You can even use UiBinder to put
those two views within the higher level view. So your DockLayoutPanel
might be your base widget for your higher level view, and you might
have MyWestView to the west and MyCenterView to the right. Then it's
just a matter of binding the presenters to the instances of the views
the higher level view references.

javascript libraries using GWT and have been for some time.  Ray
Cromwell created the GWT exporter library for this exact purpose for
his own usage and open sourced it.  While bootloaders seem expensive
it is the only way to deliver the most efficient code to the client.
There is no possible way for code size to grow when compiled because
if you go far enough every method will eventually make it to a JSNI
method, so what you are missing in your calculations is all the code
supplied by google and the small overhead code involved with the
bootloader.  However, there is a linker available to create only one
output, but in order for this to work the compilation must result in
only one permutation, which is almost impossible unless you know the
browser your client will be using.  You asked: Is there a way to crop
out all the unnecessary cruft GWT seems to think I need?.  You can
write your own linker if you feel that you know better than google
when it comes to the bootloader, but as far as the compiled code
itself; the GWT compiler has very aggressive dead code elimination, so
any output code will be used at some point.

 I've done quite a bit of searching to find any information about this,
 but it seems that people are more concerned with writing GWT libraries
 to keep in GWT before compilation.

 I would like to write the libraries I frequently use in my projects in
 GWT, then compile and expose them to hand-written Javascript.  I have
 several issues with the way GWT seems to handle what I want to do:

 1) Bootstrapping.  I understand that the iframe loading method is
 highly efficient for large codebases so as to make the page non-
 blocking, but for a small library bootstrapping is overkill.  To test,
 I tried writing my TableGenerator library (a 7kb handwritten non-
 minified library) in GWT.  The result was a 6 kb deferred binding
 loader file (table.nocache.js) and 4 permutations of compiled JS
 weighing in at 20-30kb each.  Which brings me to issue #2

 2) For compiling the code, GWT seems to produce LARGER codebases.
 Fast, yes, but how does 3-5kb of source result in 20-30kb of compiled
 javascript? Is there a way to crop out all the unnecessary cruft GWT
 seems to think I need?

 3) I would prefer to not have a bootloader - I anticipate the compiled
 form of my code is going to be smaller than the bootstrap code and
 would rather it just be loaded.  Is there a compilation option to
 disable permutations and output (obviously more to handle different
 implementations) code that works in all browsers?

 Sincerely,
 Scott Rabin

Re: First GWT question: DockLayoutPanel and presenter/views

2010-07-26 Thread PeteUK

Dane,

Thanks for your response. I have probably been thinking too rigidly
about the presenter/view paradigm and concluding that presenter/view
is 1) for the top level of the application only and 2) only 1
instantiation of a presenter/view at any one time.

Now I see that it can be as fragmented as you want it to be. I shall
experiment...

Thanks,

Pete

 I have done exactly that for an application. There's no reason you
 cannot have a view, with a corresponding presenter, that contains two
 views that have their own presenters. You can even use UiBinder to put
 those two views within the higher level view. So your DockLayoutPanel
 might be your base widget for your higher level view, and you might
 have MyWestView to the west and MyCenterView to the right. Then it's
 just a matter of binding the presenters to the instances of the views
 the higher level view references.

  Hi Tanguy,

  Thanks for the reply. I had read the blog link you posted (and part
  II).

  In the Contact application, the *entire* application area is initially
  taken up with the contacts list. When a contact is chosen for editing
  (or the Add button pressed), the *entire* area is replaced by the edit
  contact view.

  I see the DockLayoutPanel as being different to this. Let's assume the
  Mail application was to be changed to be a bit more Outlook like. The
  change being a calendar option that could be chosen from the left hand
  side (where Mailboxes, Tasks, and Contacts are). When that calendar is
  chosen, you don't want the entire application area to be replaced,
  you'd just want the two split windows in the centre area to be
  replaced by a big calendar.

  I am wondering how that would be orchestrated within the application?
  Would MVP be used here, and if so, how?

  Thanks,

  Pete

Hello,

I've been investigating GWT recently and want to start writing with
it. This is my first question on here, so pardon my ignorance.

I had just got my head around presenters and views. I then tried out
the Mail application that ships with 2.0.4 Eclipse plugin and this
looks really good. Looking at the source code though, I cannot see any
presenters or views and wonder if when using DockLayoutPanel (as the
Mail application does), would one also use presenters and views? If
so, how would they be used with the DockLayoutPanel? What portion of
the DockViewPanel would a view represent?

Thanks,

Pete

Displaying google maps with IE7

2010-07-26 Thread George Georgovassilis

I've recently run into the following rather bewildering issue where
maps display fine in all browsers but IE6 and IE7.

My GWT 2.0.4 client app is using GWT maps API 1.1 jar (against maps
API 2). The maps API loads ok, but IE6 and IE7 won't display the map
widget content - no errors thrown.

Interestingly, when the user agent is pinned to ie8 in the module
file then maps will display fine even on IE7.

Has anyone run into this before?

Hi Greg,

Just download the GWT version you want, unpack it into a directory, and
add the directory via the GPE as an alternate version. Be aware, though,
that the GPE GWT 2.x compile command line arguments may not match GWT
1.7, so you might not be able to use the current Compile widget with
1.7  IOW, you might need a custom Eclipse Java launch to compile 1.7

Re: Multiple remote service implementations

2010-07-26 Thread Vinicius Carvalho

I'm still looking for a solution for this.

My problem, is that I'm creating a widget, and that widget relies on a
remoteservice. But I have different service implementations, that must
implement the same interface. One way I found of doiing this is having
2 interfaces that extend the same interface for instance:

MyRemoteService1 extends WidgetInterface

MyRemoteService2 extends WidgetInterface


When using the widget, I pass the constructed service to its
constructor:

MyWidget m = new MyWidget(GWT.create(MyRemoteService1);
MyWidget m2 = new MyWidget(GWT.create(MyRemoteService2);

The problem with this, is that the view that contains my widget is
going to have a dependency with the widget's service, and that should
be bound only to it.

So is there any way, to have several implementations of same interface
to create a GWT service RPC?

Regards

 I'd like to emphasize, as stated above, that printedbooksare out-

 that, even though in the 2009 Google IO, Google was already pushing
 for the MVP pattern, and all the other goodies that make enterprise

 covered in any of thebooksin great detail.

 In fact, most of thebooksfeel like a HOWTO, and not worth your money
 in my opinion.

 Just to get you started, I would suggest you go through the GWT

GWT Client HTML Page and Server Services in separate war files

2010-07-26 Thread gopinath.chand

Hi,

   I'm new to GWT so I please excuse me for any primitive question...

1. We have our client generated HTML, JS in a separate war file - This
war file is served from root context /
2. We have another war file which has server service components - This
war file is served from context /bizlogic

None of our transfer objects implement IsSerializable, but they do
implement Serializable. It was working when both server and client
were in the same war, but stops working when they are separated.. I am
getting an exception saying Object not serialized for security
reasons, since it does not implement IsSerializable. But when I make
those objects implement IsSerializable it works perfectly fine.

RemoteServiceServlet.java::loadSerializationPolicy() - It looks like
module name and context path should match, but that's not the case
with us. Is that a problem? any suggestion/advice on how to proceed.

Thanks for your time..

Serialization problems

2010-07-26 Thread Vinicius Carvalho

Hello there. We have our domain model files in a separate jar

com.acme.model is the base package for it

in our gwt.xml file we have source=model/

And everything was ok. We then add a new subfolder: search

com.acme.model.search

And all classes there implement java.io.Serializable just like the
other model classes

But now, we get

com.google.gwt.user.client.rpc.SerializationException: Type 'xxx' was
not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and
did not have a custom field serializer. For security purposes, this
type will not be deserialized.

When invoking the remote service. The odd part is that it never
happened for the other classes that only implemented
java.io.Serializable.

I though that the source directive at the xml was recursive, do I need
to add each package?

 constructor:

 MyWidget m = new MyWidget(GWT.create(MyRemoteService1);
 MyWidget m2 = new MyWidget(GWT.create(MyRemoteService2);

 The problem with this, is that the view that contains my widget is
 going to have a dependency with the widget's service, and that should
 be bound only to it.

 So is there any way, to have several implementations of same interface
 to create a GWT service RPC?

 Regards

  Hi there!

  Since GWT creates the binding with the server using:

  GWT.create(Interface)

  What if I have several services implementations for the same
  interface? Is it possible to handle?

  Regards

Re: GWT Error Unable to find .gwt.xml

This is a generic error and can be caused by many different things.

1) Malformed include in gwt.xml
2) Classpath issues
3) Malformed script tag in the head of the html file
4) Trying to use a non-GWT project

I have also randomly seen this error in hosted mode and a Ctrl+F5
usually fixes it.  This used to be a common occurrence before OOPHM
with Eclipse and rename-to combined with an external server, so if you
are using an older version of GWT(pre 2.0) I suggest updating.

 Hi Community,
 many of you know the following problem:

 ERROR] Unable to find 'uivers2/Uivers2.gwt.xml' on your classpath;
 could be a typo, or maybe you forgot to include a classpath entry for
 source?

 Has anyone solved it? Could you please say me what I have to do? I
 imported the JAR of the newest incubator of gwt, I am working with gwt
 2.04.

 Regrads,
 soeren

Re: Displaying google maps with IE7

Hello Eric,

The page is in standards mode. How do I debug this?

 First, make sure your hosted html page is set to standards mode.  The
 first line should be something like:

 !doctype html

  I've recently run into the following rather bewildering issue where
  maps display fine in all browsers but IE6 and IE7.

  My GWT 2.0.4 client app is using GWT maps API 1.1 jar (against maps
  API 2). The maps API loads ok, but IE6 and IE7 won't display the map
  widget content - no errors thrown.

  Interestingly, when the user agent is pinned to ie8 in the module
  file then maps will display fine even on IE7.

  Has anyone run into this before?

Re: Using the Eclipse plugin to install a previous version of GWT

2010-07-26 Thread Rajeev Dayal

Hi Greg,

Jeff is correct; even though you cannot download the GWT 1.7 SDK in bundled
form, you can still download the zip file separately, unpack it, and then
add the SDK to GPE using this method:

http://code.google.com/eclipse/docs/using_sdks.html

http://code.google.com/eclipse/docs/using_sdks.htmlThe compilation should
work even when using GWT 1.7.

Hi,

thing I could see was GWT 2.0.4.

Hi Greg,

Just download the GWT version you want, unpack it into a directory, and
add the directory via the GPE as an alternate version. Be aware, though,
that the GPE GWT 2.x compile command line arguments may not match GWT
1.7, so you might not be able to use the current Compile widget with
1.7 IOW, you might need a custom Eclipse Java launch to compile 1.7

Re: What changed in 2.0?

Thanks.  It would be nice if one or both of these were linking from
the Documentation page.

  Where do I go to find out what changed from 1.7 to 2.0?
