I have similar problem as Jens 
herehttps://groups.google.com/forum/#%21topic/google-web-toolkit/OsDpLtBoTQo. 
The general Problem is: How to prevent a (select some item)-activity to be 
restarted if someone selects an item and the app is go(ing)To(Contentplace) 
to show item's content. (if you would ask me: i don't want to go to a new 
place, i just want the url to be updated. the rest would be done like in pre 
Activities/Places era (event bus, custom events).)
But there is no other way to update the url (make history entry) than to go 
to a place, right? So Caching/Filtering activity mappers come in and want to 
be used. The problem is i can't get the to work. I tried it with Mauro 
layoutMVP 
example, http://95.110.143.4/layoutmvp/layoutmvp.htmlbut soon i realized 
that the chaching there isn't working in the way needed (i.e. the emailList 
activity is started again on every email selection). So how to get some 
chaching/ filtering for a select activity. At the moment i have something 
like that:

The Mapper for Content Area:

public class ContentMapper implements ActivityMapper {

private ClientFactory clientFactory;

public ContentMapper(ClientFactory clientFactory) {
this.clientFactory = clientFactory;
}

@Override
public Activity getActivity(Place place) {
if (place instanceof SelectPlace) {
return new ContentActivity(null, clientFactory);
}

if (place instanceof ContentPlace) {
return new ContentActivity((ContentPlace) place, clientFactory);
}
return null;
}
}

The (primitive) Mapper for select area:

public class SelectMapper implements ActivityMapper {

private ClientFactory clientFactory;

public SelectMapper(ClientFactory clientFactory) {
this.clientFactory = clientFactory;
}

@Override
public Activity getActivity(Place place) {
if (place instanceof SelectPlace || ContentPlace) {
return new SelectActivity(clientFactory);
}
return null;
}
}

With this on every selection a new SelectActivity is started - bad :-(. So 
How to implement a Caching/Filtering Mapper that don't recreates select 
activity (select activity is never to be recreated - only updated) on 
goTo(new contentPlace)? 

thx in advance

GWT integration to the cloud

2011-06-24 Thread Amit

On Google I/O 2010, the VMware- Spring Roo tool was demonstrated. It
shows how one can quickly build a simple GWT application, where Roo
got only small and simple input and generated the entire code. A year
later, in one of the sessions of Google I/O 2011, a question was asked
regarding the collaboration of Google with VMware and the future of
Roo and its GWT plugin, however this time no real answer was given.
I wonder what is the status of Roo and the GWT plug-in from your eyes,
is it going to be a tool ready for production (for real applications
rather than demo only).
Also what is the reccomended way for integration of GWT with the cloud
for an entrprise application - e.g., is there any intention to provide
integration with the VMware spring V-Fabric products?
What is the future of GAE in that sense given the following report
http://gigaom.com/cloud/can-google-app-engine-compete-in-the-enterprise

Waiting for your comments,

Wonderful, wonderful question Amit. I'm all ears for a genuine answer on
this one (NOT the usual This is a springsource-team problem, when it's
clearly so important to GWT).

Thanks

DateBox and TimeZone

2011-06-24 Thread Eric

Hello All,

How can I force a GWT DateBox to choose dates in a particular time
zone?  Users off this application might be in many time zones, but,
for this purpose, any date entered should be in America/Denver.
Since one of the people who enter this information works in eastern
time the dates he enters appear a day before the date he enters. I've
searched this list and googled in general, but I can't find how to
override the default time zone for a DateBox.

Code:

Some constants universally available:

  public static final TimeZoneConstants timeZoneConstants =
GWT.create(TimeZoneConstants.class);
  public static final TimeZone usMountain =
TimeZone.createTimeZone(timeZoneConstants
  .americaDenver());
  public static final DateTimeFormat dateDtf =
DateTimeFormat.getFormat(MM/dd/);


Code that displays the date:
  String displayDate = Constants.dateDtf.format(d, usMountain)

The DateBox where the date is entered:
  DateBox.DefaultFormat pickerFormat = new
DateBox.DefaultFormat(Constants.dateDtf);
  DateBox myDb = new DateBox(new DatePicker(), null, pickerFormat);

There are many places I could expect to be able to set the Time Zone:
on the DateTimeFormat, on the DateBox.DefaultFormat, on the DateBox,
in DateBox.getCalendarModel() . . .  Any I blind? I can't see the
method anywhere.

Thanks,
Eric

Re: Question about new activities on place changes

Thomas/Jens.

... and the CachingActivityMapper will then return the same activity 
instance as previously ...

how to achieve that? i am able to create caching/filtered mapper but Filter 
returns a place and all my mappers are returning new activities? How to 
get / hold the old activity without saving it in a global field (singleton 
approach?!)? so my problem is not to filter the place - redirect to another 
place but to get the old activity returned.

Problem in tracing the exception of RequstFactory Application

2011-06-24 Thread saurabh saurabh

Hi all,
I have a application kind of a DynatableRf , it is using
RequestFactory and Editor API. When I call for a method like find()
or  something like that on a RequestContext, this call gets back to
DAO object on server and it tries to send back the result but in
between something happens here and exceptions are thrown. Seeing the
StackTrace of exception, I am not able find out whats gone wrong in
there. Through debugging and Logging I saw there parts of my code till
server is working properly.

I guess 'Caused by: java.lang.RuntimeException: Server Error: null'
could be clue

I am really tired of this. Any idea how can I trace or resolve it.
Thanks in advance.

Navigation problem

2011-06-24 Thread TubaMan

Hi all,

I experience a navigation problem. This is the situation:

There is a TextBox, when there is input in the TextBox (KeyUpEvent) a
message is shown beneath the TextBox. The message is a Label that is
added to the parent-widget of the TextBox.
OnBlur the message has to disapear. This is done by
label.removefromParent().

However using the keyboard, leaving the TextBox by tab-key it is going
OK, but using the mouse, clicking a RadioButton below the TextBox, the
RadioButton got Focus, but is not selected!

I think the cause of this problem is that by removing the message, the
RadioButton scrolls up, and clicking the RadioButton failed because
the RadioButton is no longer at that position on the screen, but it
gets the focus because it is the last widget before the point that is
clicked.

Does anyone know a solution to my problem?

Thanx,
Jasper

Re: Question about new activities on place changes

The common pattern is ActivityManager → FilteredActivityMapper → 
CachingActivityMapper → MyActivityMapper.

The FilteredActivityMapper's Filter transforms places to common cases that 
can be compared with .equals(). In a Spring Roo app (at least of the kind 
that came with the first version of the Roo/GWT integration), the filter for 
the master region transformed EntityPlace(SomeProxy.class, someId) into 
EntityListPlace(SomeProxy.class) for instance. So whichever the someId of 
two consecutive EntityPlace(SomeProxy.class, …) the filtered places would 
compare equal. It could have transformed them into EntityPlace with the same 
proxy type and, san, an empty ID, but transforming to the EntityListPlace 
makes the MyActivityMapper easier to write, as it only has to handle 
EntityListPlace.

The CachingActivityMapper compares two consecutive places with .equals() to 
decide what to do. If they're equal, it returns the previously returned 
activity (a reference of which it keeps in a field). Otherwise, it asks the 
MyActivityMapper to provide an activity for the place (generally a new 
instance), and it stores the place it was passed as argument, and the 
activity it returns, into fields; for the next round.

GWT into JUNIPER

2011-06-24 Thread obesga

Hello

I've been developing a GWT proyect for internal use in my company.
The web is accesed from inside and from outside the compan main
network, 'outsiders' access througth Internet to the web; which has
sensible information.

To add a extra security layer, the system team is deploying a JUNIPER
installation, which has a 'advanced parser and rewriter' (as an
internal advanced reverse-proxy) to acces ccc webs - like mine.

Now, with the JUNIPER CIE ( content internediation engine - the
'advanced parser and rewriter') GWT RPC doesn't work at all.
It responds 'Error 500' failures.

I don't know how to avoid this errors and make the app work again, if
possible

¿ Anyone knows ? Thanks !


PS. yes, i'm considering rewritting RPC's calls into JSON/HTTP calls;
but prefer to avoid it if possible

Re: AsyncCallback timeout

You can customize the request by setting an RpcRequestBuilder on your 
service 
stub: 
http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/rpc/RpcRequestBuilder.html
 
(cast your service stub to ServideDefTarget and call setRpcRequestBuilder 
with your own subclass, that can then call setTimeoutMillis on the 
RequestBuilder: 
http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/http/client/RequestBuilder.html#setTimeoutMillis(int)
 
)

Re: GwtCanvasDemo Question

2011-06-24 Thread Philip Rogers

Hi Sean,

It's definitely not the cleanest code for understanding! The magic happens 
in lens.java::draw(backbuffer, frontbuffer). What's happening is the lens 
calls:
front.drawImage(back.getCanvas(), 0, 0);
which copies (blits) all the pixels from the back to the front. The 
backbuffer is never added to the root panel because it's only used as a 
temporary store of pixels for this operation.

By the way, if you're interested in high performance javascript games, you 
may be interested in the ForPlay http://code.google.com/p/forplay/project. 
It's built using GWT and is targeted at multiplatform (including 
Html5) games.

Re: GWT into JUNIPER

Is your problem with GWT-RPC (causing the 500 error status) an issue with 
loading the policy file? If so, you can override a few methods in your 
RemoteServiceServlets to change the default behavior.

If you really have no choice but to abandon GWT-RPC, I'd highly recommend 
RequestFactory, rather than hand-made JSON/HTTP.

POJO to JSON

2011-06-24 Thread obesga

Hello

I've a problem with an application, the application works fine but the
new 'firewall' system drops the RPC calls.
So I'm thinking about rewriting GWT-RPC calls to GWT-JSON

I've a lot of simple POJO objects that are used into the app, the
classes are written and can't change very much ( as they are used
acrros the server, including database DAO)

¿ which are   your preferred / less painfull (less boilerplate
code)methods to convert from JSON to POJO in GWT ?
- Autobeans
- JSON Overlay types
- Use simple HTTP with String parse
- Other ( explain please...)

Re: GWT 2.1 MVP Multiple activities clarification help

There are a couple of bugs in my example related to the filtering/
caching of horizontal/vertical master activities:

1) the order between caching and filtering activity in
CachingHorizontalMasterActivityMapper and
CachingVerticalActivityMapper is wrong:

public class CachingHorizontalMasterActivityMapper implements
ActivityMapper {
...
  public
CachingHorizontalMasterActivityMapper(HorizontalMasterActivityMapper
horizontalMasterActivityMapper) {
  ...
ActivityMapper filteredMapper = new FilteredActivityMapper(filter,
horizontalMasterActivityMapper);
cachingActivityMapper = new CachingActivityMapper(filteredMapper);
  }
...
}

This way, we are caching the activity associated with MailDetailPlace,
not with MailListPlace as intended.

The right filtering order is:
public class CachingHorizontalMasterActivityMapper implements
ActivityMapper {
...
  public
CachingHorizontalMasterActivityMapper(HorizontalMasterActivityMapper
horizontalMasterActivityMapper) {
  ...
CachingActivityMapper cachingActivityMapper = new
CachingActivityMapper(horizontalMasterActivityMapper);
filteredActivityMapper = new FilteredActivityMapper(filter,
cachingActivityMapper);
  }
...
}

2) moreover, to let CachingActivityMapper successfully detect
instances of the same Place type, we need to ovverride equals method
on our Places:

public class MailListPlace extends MailPlace {
  @Override
  public boolean equals(Object otherPlace) {
return this == otherPlace || (otherPlace != null  getClass() ==
otherPlace.getClass());
  }
  ...
}

I've uploaded fixed versions of both non-gin and gin version of the
example code at the usual url:
http://95.110.143.4/layoutmvp/layoutmvp.tar.gz
http://95.110.143.4/layoutmvp/layoutmvp-gin.tar.gz

Re: Question about new activities on place changes

i didn't understand much thomas - sorry.

in meantime i wrote a little sandbox app to boil my problem down to a 
minimum amount of code. My Problem is either i didn't understand anything or 
CachingActivityMapper is a misleading term because where is the cache and 
the cached activity. All i got so far is a class (CachingMenuMapper) with 
a FilteredActivityMapper.Filter. But its not filtering any activities it 
only maps places. And every place is mapped via some getActivity(place) to 
get new activity.

So i understood filter/mapping places via FilteredActivityMapper.Filter 
but i don't know how to write a MyActivityMapper (the end in your chain) 
that is able to return an old activity. i am sure i am miss something in 
between but at the moment my old activity (menuList) is gone at the moment i 
go to contentPlace (and reading here i think there must be a way without 
saving activity in global field).

No, it's nothing with the server which server GWT pages and RPC.

The outsider connects to JUNIPER, JUNIPER asks the GWT-Server the page
and rpc's and returns it to outsider.
It works like 'man-in-the-middle'

But it doesn't like RPC calls, as I see..

Re: GWT integration to the cloud

We've seen very little interest in GWT-Roo integration on this forum. It
seems that most folks want to use GWT RequestFactory and Activities  Places
without code generation, so we've chosen to prioritize effort around making
that easier (for example, ServiceLocators and issues 5807, 6234 make it
possible to inherit generic service methods vs. generate them).

Technically, GWT-Roo integration is structured as a Roo add-on so Spring
needs to be at least involved in any further work.

Are you just wanting to kick the tires or have you already adopted Roo and
have a really strong use case for GWT integration also?

Re: Question about new activities on place changes

FilteredActivityMapper and CachingActivityMapper are the one from

not tested, but should work, according to David above. Your DevMode will run

course a bit harder if your desktop is not running an X server (such as 
Windows), but you can install one quite easily.

Re: RequestFactory: creating proxies on client and constructors

Hi Ryan,

The proxy you get from RequestContext.create() won't be updated
automatically. Your persist method should return the newly persisted object
from the server.

Does that help?

 Thanks David, for confirming my suspicions.

 I've got this working now so that immediately after I
 RequestContext.create my proxy, I call a method on the server to
 persist it.

 In side that server method, I refresh the state of the object after
 saving it, because a database trigger populates some tables associated
 with the object when it is first created.  On the server side, I see
 those fields being assigned values in my debugger after the refresh.
 I do update the version number field for the object on the server in
 my service method.

 However, on the client side, the proxy returned by
 RequestContext.create does not have those new values; the collection
 containing them is still null, as it was before I persisted the
 object.

 I have some ideas on how to fix this, but I'd love to hear suggestions
 on the best way to do it.  I feel like the client-side event bus stuff
 could be involved here, but honestly I don't know much about how that
 works - where is a good place to look for docs (the getting started

Re: POJO to JSON

 Hello 

 I've a problem with an application, the application works fine but the 
 new 'firewall' system drops the RPC calls.


I'd be interesting to understand why it drops them, so that your new 
protocol won't be blacklisted either.
 

 So I'm thinking about rewriting GWT-RPC calls to GWT-JSON 

 I've a lot of simple POJO objects that are used into the app, the 
 classes are written and can't change very much ( as they are used 
 acrros the server, including database DAO) 

 ¿ which are   your preferred / less painfull (less boilerplate 
 code)methods to convert from JSON to POJO in GWT ? 
 - Autobeans


You won't be able to reuse your POJOs, but if you can convert them to 
interfaces, then that's an option (AFAICT, you can also have POJOs 
implementing the interface and thus wrap a POJO instance in an AutoBean; but 
that'd only help with serializing, IIUC, not deserializing JSON to POJOs)

- JSON Overlay types 


You won't be able to reuse your POJOs on the client side; and you'd have to 
serialize them to/from JSON on the server-side (fortunately, there are many 
tools to help you: GSON, Jackson, etc.)
Have a look at the Piriti project too as, IIRC, it could handle that quite 
easily (including the GWT-client part)
 

 - Use simple HTTP with String parse


I don't see any advantage over JSON, and the major drawbacks of having to 
write a parser and serializer by hand.
 

 - Other ( explain please...)


RequestFactory:
 - you'll leverage your POJOs on the server-side, and transforming GWT-RPC 
services to RF ones should be really easy.
 - you'll have to write the proxies, but that could be automated (that's 
what we do). If you domain model is stable enough, you could also simply 
iterate with your IDE's extract interface feature and a bit of tweaking by 
hand.

Re: GWT 2.1 MVP Multiple activities clarification help

2011-06-24 Thread Ustad

Thanks so much for the update Mauro.I'm still struggling to wrap my head
around MVP and activities  places.I'm going to start very small and use
your code as my baseline.   Just some clarification Mauro, the idea of the
MVP pattern is used to decouple the view from the presenter with the intent
to make the view as 'dumb' as possible to facilitate a seamless swap out to
its mock counterpart during testing, and the activities and places is the
underlying framework Google has provided to help essentially manage user
history but at the same time activities can be thought of as the presenter
and used synonymously ?Do I have it totally wrong?  I guess as a
beginner, I'm seeing so many different implementations where views implement
interfaces in presenters and presenters implementing interfaces in views
that I can't get a concrete grasp of how I should approach a simple
design?The idea of the presenter defining the contract for the view and
the view providing that implementation makes sense to me sorry I
probably have not made any sense   thanks for your help and your
guidance to the community at large!

 There are a couple of bugs in my example related to the filtering/
 caching of horizontal/vertical master activities:

 1) the order between caching and filtering activity in
 CachingHorizontalMasterActivityMapper and
 CachingVerticalActivityMapper is wrong:

 public class CachingHorizontalMasterActivityMapper implements
 ActivityMapper {
 ...
  public
 CachingHorizontalMasterActivityMapper(HorizontalMasterActivityMapper
 horizontalMasterActivityMapper) {
  ...
ActivityMapper filteredMapper = new FilteredActivityMapper(filter,
 horizontalMasterActivityMapper);
cachingActivityMapper = new CachingActivityMapper(filteredMapper);
  }
 ...
 }

 This way, we are caching the activity associated with MailDetailPlace,
 not with MailListPlace as intended.

 The right filtering order is:
 public class CachingHorizontalMasterActivityMapper implements
 ActivityMapper {
 ...
  public
 CachingHorizontalMasterActivityMapper(HorizontalMasterActivityMapper
 horizontalMasterActivityMapper) {
  ...
CachingActivityMapper cachingActivityMapper = new
 CachingActivityMapper(horizontalMasterActivityMapper);
filteredActivityMapper = new FilteredActivityMapper(filter,
 cachingActivityMapper);
  }
 ...
 }

 2) moreover, to let CachingActivityMapper successfully detect
 instances of the same Place type, we need to ovverride equals method
 on our Places:

 public class MailListPlace extends MailPlace {
  @Override
  public boolean equals(Object otherPlace) {
return this == otherPlace || (otherPlace != null  getClass() ==
 otherPlace.getClass());
  }
  ...
 }

 I've uploaded fixed versions of both non-gin and gin version of the
 example code at the usual url:

  I've got this working now so that immediately after I

  In side that server method, I refresh the state of the object after
  saving it, because a database trigger populates some tables associated
  with the object when it is first created.  On the server side, I see
  those fields being assigned values in my debugger after the refresh.
  I do update the version number field for the object on the server in

  However, on the client side, the proxy returned by

Re: Question about new activities on place changes

ok thats clear enough but there is my problem: providing an activity mapper 
that returns a cached activity. how does such an getActivity -method looks 
like (my only idea is to return an activity saved in some global field). but 
i can't believe that CachingActivityMapper could provide a cached 
activity?!
so no matter in what place the filtering ends, it ends always in an 
ActivityMapper's getActivity-Method that returns a new Activity. My question 
is how/where to get the cached activity? Will always the getActivity be 
called and i have to manage to get a cached one or is this wrapped by 
MyCachingActivity's filter? in latter case, how to avoid the call 
getActivity of wrapped Mapper? The Filter returns a place, i tried to always 
return the same place ...return place;... - but it doesn't matter, allways 
a new activity is created.

(in meantime i got Mauro's new example to work - but understanding it is now 
working will be difficult. - at least for me)

You're right.

(note that the fact that activities are presenters is an implementation 
choice: nothing and nobody forces you to do so; you can choose that your 
activity will make use of a presenter as a distinct class, or that your 
activity is the view, or even that you don't use MVP at all for your 
activity –it can make sense for very small things with few to no interaction 
at all–)

It doesn't matter where your interfaces live (nested in the presenter, 
nested in the view, in their own files: it doesn't matter; you decide what 
you prefer). The fact is that if you want to decouple your presenter from 
your view, to be able to mock the latter when unit-testing the former, they 
should be talking to each other through interfaces (depending on your 
mocking tool, it might not be strictly necessary, but I believe it helps 
understanding the big picture anyway). If your view needs to talk back to 
your presenter, then it's a good idea to define an interface to formalize 
the contract for the presenter, in the same way you defined an interface to 
describe the contract for the view.

Re: Problems with filtering/ caching activities

in meantime i tried your code (in my own eclipse maven project) - it's 
working as expected. My first mistake was to think, that the cached activity 
is used if Filter returns place but the opposite is true. But that didn't 
helped much. For some reason if your filter 
(CachingHorizontalMasterActivityMapper) returns new MailListPlace the  
HorizontalMasterActivityMapper 's getActivity is not called and a cached 
activity is returned - but why?

in my case if i return new MenuPlace() the Mappers getActivity is called and 
i get a new activity! What criteria yields to returning a cached activity 
(in your code) or  calling the wrapped mapper and returning a new activity? 
(i do not even know how to set breakpoints to see what's happening: my code 
stops after returning new Place in wrapped Mapper getActivity your code 
doesnt't.)

thx thomas for your never ending endurance, i guess i came a little closer

Sorry for that: But what is the value of lastPlace and lastActivity after 
construction time?

And i miss the connection with Mauro's current code: If His CachingMApper 
returns new MailListPlace() the cached activity is used. But if the same 
place is returned a new activity is created. But reading the source says 
some places have to be equal to get lastActivity. So what place should be 
equals to what place on calling the method Place filter(Place place), to get

Hi, 

Thomas you're right: You can use Piriti (http://code.google.com/p/piriti/)

Please note that Piriti is only meant to be used on the client side. It's

Re: Problems with filtering/ caching activities

thx for this picture, my problem is i don't know what place is compared to 
cachedPlace and what is cached place. Or where  the comparison takes place? 
'Til now i thought on returning the given place in filter-method i am sure 
the 2 places are equal. but debugging your updated code shows that on 
returning new MailListPlace the cached activity is used (thats because you 
overrode equal of MailListPlace). But how to return a place that is exactly 
the same as before ((new MailListPlas).equal(to What) ??).

 thx thomas for your never ending endurance, i guess i came a little closer

 Sorry for that: But what is the value of lastPlace and lastActivity after

both null, of course..

 And i miss the connection with Mauro's current code: If His CachingMApper
 returns new MailListPlace() the cached activity is used. But if the same
 place is returned a new activity is created. But reading the source says
 some places have to be equal to get lastActivity. So what place should be
 equals to what place on calling the method Place filter(Place place), to get
 a cached activity?

new Places are instantiated every time a placeChangeEvent occurs. So
when comparing new place with cached place, even if the Places are of
the same type (say MailListPlace) the instances are not, and that's
why we need to override Place.equals to compare class type and not
instances to let CachingActivityMapper works.

custom event + event bubbling

2011-06-24 Thread isern

Hello,

I was wondering, is it possible to bubble up a custom event through
the widget hierarchy?

The EventBus solution seems great but in some cases I'd like to catch
certain events related to the current context that's usually given
by the UI.

Thanks..!

Re: What has happened to the GWT designer for Eclipse Indigo?

2011-06-24 Thread Eric Clayberg

There is something weird going on with Eclipse p2 which we are
investigating. Here are four work arounds that will work:

1) Unload WindowBuilder Core and WindowBuilder Core XML (from Indigo)
and then load GPE, or

2) Install GPE first, followed by WB from Indigo, or

3) Use the Eclipse Java Developers distro (w/ WB already installed)
and load GPE into that, or

4) Load WindowBuilder from code.google.com (http://dl.google.com/
eclipse/inst/d2wbpro/beta/3.7) and then load GPE

Aw: Re: Question about new activities on place changes

2011-06-24 Thread Jens

Its pretty easy. If you have looked at the source code of 
CachingActivityMapper you see that it only calls place.equals(lastPlace) to 
check if it has to return the previous activity or has to create a new one. 
After construction of CachingActivityMapper both lastPlace and lastActivity 
are null and thus the first place.equals(lastPlace) will always return false 
and a new Activity for that requested place is created. Lets say the first 
place change has been done via placeController.goTo(new EntityPlace(1)) and 
now a second place change occur via placeController.goTo(new 
EntityPlace(2)).

The CachingActivityMapper will not return a cached activity if you do not 
have overwritten .equals() and .hashcode() in the EntityPlace class. If you 
do not overwrite both methods, the ones from Object will be used and 
.equals() in Object does a instance check (return this == other). But as you 
create new instances of EntityPlace the equals call in CachingActivityMapper 
will always be false.
So if you overwrite equals/hashcode you would normally check if the class 
types are the same and if all variables (= internal state) are the same. If 
both is true then both places are equal. But even with such an equals method 
in EntityPalce the CachingActivityMapper still does not work because now new 
EntityPlace(1).equals(new EntityPlace(2)) is still false as they do not have 
the same internal state.

Thats why you use a filter. In your Place filter(Place place) method you 
would do something like:

Place filter(Place place) {
  if(place instanceof EntityPlace) {
return new EntityPlace(null);
  }
}

So you nullify that state of the place and now the CachingActivityMapper 
will always receive an EntityPlace without any state information and thus 
equals will return true and thus the cached activity for that place type 
will be reused. So thats the basic idea on how to make CachingActivityMapper 
work. By the way the PlaceController will of course always have the correct 
Place with the correct internal state if you call 
placeController.getWhere().

In my case I've done it in a slightly other way. So I have taken my 
MainActivityMapper of my application and in its getActivity method I do:

Activity getActivity(Place place) {
  if(place != null  this.lastPlace != null   place.getClass() == 
this.lastPlace.getClass()) {
return this.lastActivity;
  }

  this.lastPlace = place;

  if(place instanceof XYZPlace) {
return new XYZActivity(place);
  } else if() {.} .
}

That way I will always get a cached activity if two or more places in a row 
have the same type. So basically I integrated the caching into my normal 
MainActivityMapper and I do not need an extra Filter and do not need GWT's 
CachingActivityMapper. 
As every activity is now cached it has to implement PlaceChangeEvent.Handler 
to get notified on each place change. That way the activity can update its 
state based on the place although the activity is cached. In the way I did 
it I wouldn't need to implement .equals/hashcode in my places but I have 
done it because placeController will not fire a place change event if two 
places are equal (maybe you somehow accidentally called 
placeController.goTo(new EntityPlace(1)) twice in a row).

But keep in mind that I do it that way because I have only one 
ActivityMapper and one Activity for each Place. It was the easiest solution 
for me at the time being because I migrate the app to Activities and my 
activities deal with both list selection and loading of the selected object. 
But maybe my example shows you that its always a bit application dependent 
how to implement things. Once you got the basic idea how you can cache 
activities you can make it fit into your application.

 Hello Alexandro,

 Thank you for your kind words.
 I m glad that you like the project. I m also happy that it can help you
 solve some of the problems you have.
 Gwt4Air is  a free time project. We use it internally at the company i work
 but i dont get paid for that. It s small company so i decided to play the
 nice guy :).But I wish I could do this full time  dough.

 i m know the link you provided. As a matter of fact i have a comment there.
 While searching for ideas on how to implement the Flex API i came accross
 that post. What i did not like about that solution was the fact that the
 user must deal with both sides. Flex and GWT. I wanted a more simpler
 solution where one will only programm in Java like any GWT project.
 Hopefully i did a good job at that.

 Concerning what the Adobe Engineer told you: I think  what he ment is that
  for every MXML based Flex project the MXML Compiler  does  some
 initialization work that you will have to do manually  if you dont want to
 use MXML. And that initialization is a quiet complex thing. So  he probably
 thought that no one would be crazy enough to try to figure out what the
 compiler really does . But because i wanted to use GWT to write Flex
 applicatons i had to be  crazy enough lol.

 cheers,

 Alain

  Hi,
  I just went to your project and i have to say this is just mind blowing!
  Are you doing this full time ?
  Really i wonder how you guyz come up with this kind of stuff.
  We have been struggling integrating  flex client into how existing GWT
  application.
  We ve tried this  solution here
 http://lgrammel.blogspot.com/2010/02/i-am-working-on-project-that-int...
  but  that did not scale very well. Maintining MXML/AS3, JavaScript and Java
  in the same project is a nightmare.
  Last year at Adobe Max i asked an engineer at from adobe if it s possible
  to write Flex applications without using AS3 and MXML because we wanted to
  keep everything in Java
  and he basically said that s impossible. So i wonder how do you do this ?
  I  cant wait to play to hero tomorrow at the office when i present the
  solution that will solve our problems :)

  Good work man

  Alexandro

Tree selection

In the stock Tree widget, if there is a selection made on a node and if the 
parent is closed, the selection moves to the parent node. Is there a way to 
change this behavior not to move the selection to the parent node? This 
causes some issues when we have a selection listener and the act of closing 
the parent node invokes the selection handler even though the user did not 
actually change the selection. I want to keep the behavior similar to how 
Vaadin does with their Tree control:

Just an idea, I'd try this:

driver.edit(proxy);

If I got RF right, the edited reference should be the same as the one
request.edit() returns, as it is already bound to that context.

New to GWT, Sample Project: Unable to initialize static dispatcher

2011-06-24 Thread chris mahood

New to GWT development.  Have set up environment, Eclipse/Helios 
Chrome with GWT plug in.

I am only able to connect to the development web server and run the
app about 1/4th of the time.  I am trying to identify a pattern.  I
have rebooted, restarted Chrome and Eclipse, restarted the webserver,
terminated the web app and run again, etc, and it only works about
1/4th of the time.  The other times, the web page times out and I get
a server error.

Typical error looks like this:  The client is only able to load .html,
the form (box/button) does not load and then the page times out.
Eclipse error console shows:

Unable to initialize static dispatcher
Failed to load module webap...

It works some of the time, and I have not been able to identify a
pattern of failure.

Regular expression email validation in GWT

2011-06-24 Thread creativepragmatic

Hello,

I am trying to validate a form using gwt-validation but have not been
having any success validating the email field of a POJO.  The field is
annotated as follows:

@NotNull
@Pattern(regexp = .+@.+\\.[a-z]+)
private String email;

Whenever Pattern is annotated to the above code, it fails after the
following line that I modeled after Gwt_validation_sample:

SetConstraintViolationEmail violations =
validator.validate(email);

I have added the following JARs to the classpath:

dom4j-1.6.1
freemarker-gae-2.3.18
guava-r09
gwt-validation-2.0-preview-r199
javassist
reflections-0.9.5-RC2
reflections-0.9.5-RC2.one
slf4j-api-1.6.1
validation-api-1.0.0.GA-sources
validation-api-1.0.0.GA

I am not sure if they are all required.

Thank you in advance for any help,

Orville

GWT PrecompressLinker Tomcat

2011-06-24 Thread pop.ionut84

Hi,
I've included the PrecompressLinker option in my gwt.xml file, build
the application and deploy to Tomcat. All generated js file have an
equivalent js.gz file, but Tomcat still uses non gzip files.

How can I tell Tomcat when a request comes for foo.js to check for the
existence of foo.js.gz and use it?

font-size: does not work for GWT button and flextable

2011-06-24 Thread Bob

How do you change the font size in a GWT Button or a GWT Flextable?

The standard CSS of
font-size: 150%; does not work, but
color: red; does work.

Also, font-family does not work for flexible (but does for button)

I am new to GWT.

How to Prevent GWT from translating certain methods into JavaScript

2011-06-24 Thread K. Bolino

This is a continuation of the following discussion:
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/d5315f505810304a

I have the same issue, namely that I want to be able to specify (e.g.
through an annotation like @JavaOnly) that certain methods in my
shared POJOs are for the use of the server-side code only.  My goal is
to exploit polymorphism and avoid the instanceof keyword on the
server side.

To get into a little more detail, what I'm trying to do is use the
Abstract Factory pattern to associate certain concrete classes in the
server package (which perform SQL updates, for example) with their
corresponding plain old Java objects, which are in the shared
package.  I define an abstract method in the shared parent class
(getSQL() e.g.) and then each of the subclasses provides a concrete
implementation, which returns a concrete object of a server-side class
(all of which, in turn, implement a common interface).

Needless to say, the getSQL() method cannot be translated into
JavaScript, because it depends on strictly server-side classes and
concepts.  However, I still want to share the object (i.e., its data)
between client and server through RPC.  Unfortunately, GWT throws an
error when creating the JavaScript because it cannot find the source
code for the server-side classes.

Two solutions were posed to this problem in the previous discussion,
but neither of them are helpful.

The first was to simply wrap the method body in a !GWT.isClient()
conditional, but since the method definition includes references to
server-side code (its return type, specifically), nothing is actually
hidden from the compiler.

The second was to create subclasses of the shared objects on the
server-side.  Unfortunately, this method suffers from the same
problem: the shared objects cannot know about their server-side
counterparts.  Thus, it doesn't really solve anything at all, because
any operations would still require instanceof checking to obtain the
correct server-side subclass.

Another solution mentioned was to exclude certain classes in the
module definition, but this method suffers from the same problem.

So, is there a way to exclude a specific method (in an otherwise
included class) from being compiled into JavaScript?  Of course, if
there's a better pattern that works with GWT, that would be helpful.

Thanks,
K. Bolino

hyperlinks/html

2011-06-24 Thread christian londono

Hi, im creating a plugin for an already existing website that will
incorporate a launchpad of sorts. I need a way to use a hyperlink that
will redirect me to somewhere else on the website, but as far as my
understanding of hyperlinks for gwt widgets is that it only points to
another page in the application itself and so im not sure if i can
jump somewhere else on the website. If so how can i?

Re: Log file

2011-06-24 Thread Ben Imp

The answer to that depends on which server you are using.  If its Tomcat, 
there should be a conf subdirectory with a catalina.out file in there, 
unless yours is configured differently.

Re: Apache Shiro or Spring Security??

2011-06-24 Thread Fabricio Pizzichillo

Can share how youdo it?

2011/6/22 Nicolas Antoniazzi nicolas.antonia...@gmail.com

 Here, we use Shiro since it is really easy to integrate.
 Moreover, Shiro is not tight to Spring... And that's a good thing for us
 since we use Gin on client and Guice on Server (to not multiply API).


 2011/6/22 Elhanan Maayan elh.mailg...@gmail.com

  we are exploring apache shiro with gwt integration, the reason is first
 of all, you don't spring beans for it, and 2nd is that also provides for
 session management which spring security does not.
 even folks at spring forums say shiro has much broader scope then security
 ..

Don't follow how to put toolbar in RichTextAra

2011-06-24 Thread Bob

 

I am able to get RichTextArea working with no tool bars (not to hard).

The showcase source indicates the following line: 

RichTextToolbar toolbar = *new* RichTextToolbar(taskRichTextArea);

I don't see that RichTextToolbar can be imported via eclipse like RichText 
Area can.

So, I am stuck.  How do you create toolbars in a Rich Text Area?

Any tutorials on this, using GWT 2.3 would be great.  I am new to this.

Thanks

[gwt-contrib] Re: [google-web-toolkit] r10387 committed - Add Linux support for FF5 (Gecko 5.0) in the xpcom plugin....

I tried the XPI from this commit in Firefox 4.0.1 on Ubuntu 11.04 (to check 
that it worked before upgrading to Firefox 5) and guess what: it failed!

First, it prompted me to allow the web and code server combination again 
(I'm debugging in -noserver mode) despite being already there in the 
extension's preferences (and I didn't notice any change in the preferences 
after allowing it).

Then when, as I was given a blank page, reloading it would still give me the 
same blank page. Looking at the Console view in Eclipse showed a couple 
lines per attempts (reloads):
Connection received from localhost:32884
   [ERROR] Unexpected message type QUIT; expecting LoadModule
Connection received from localhost:32887
   [ERROR] Unexpected message type QUIT; expecting LoadModule
Connection received from localhost:32888
   [ERROR] Unexpected message type QUIT; expecting LoadModule

Is this expected with this temporary version?
