yes, it is totally unnecessary.

1- you can annotate your Foo clas with @Singleton annotation.

2- alternatively you can use bind(Foo.class).in(Singleton.class)
in your GIN Module configure() method.

now you can use your Provider as you normally would,
and it gives you the same Foo instance all the time.

Re: Calculate age

2011-02-03 Thread kkpirri

Isn't there a better solution? I don't like ignoring deprecations
because doing that in the future my application won't work. I want to
make it compatible with future JVM versions.

I am thinking in calculating it with a Javscript script. I would
prefer to do it in Java but I think it's a better solution than
ignoring deprecations.

Thank you for your response.

Re: Calculate age

If you want JVM forwards compatibility, then use Calendar.
If you want GWT compatibility, then use java.util.Date and ignore the 
warnings: your code doesn't run in a JVM, what matters is what GWT 
understands. You can alternatively use 
JsDatehttp://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/core/client/JsDate.html
.
If you want both, then you can use JodaTime (there's a GWT-compatible port).

But honestly, do you really think java.util.Date will go away before you do 
some maintenance work on your app?

Hi Daniele,

You could give JPA (via Hibernate) and GWT 2.1.1 Request Factory a try.
With those, you dont need to have serializable Java classes like with
GWT-RPC before.
Request Factory uses Interfaces instead, for a) Entity/Value Proxies and
b) Service Facades (Request Context) and works seamlessly together with
annotated JPA classes.
That means your domain classes dont have to extend LightEntity.

The other option would be to find a way to marshal the LightEntities via
Axis2.

Looks like LightEntities contain properties which you dont want to send
to the client (debugString, underlyingValue). Maybe there is even a
circular reference inside where the timeout comes from.

Re: Gin, SingleInstanceProvider?

using a Provider always result in delayed on-demand instantiation,
the object is not create unless you get() it.

however, if you don't bind it in Singleton scope,
this deferred on-demand instantiation will create a new instance every time 
you call get() on the Provider.
in cases where you only need one instance, you can bind your provider in 
Singleton scope.

please have a look at Guice documentation below: the comments section at the 
very end.
it is similar in GIN.

Re: GWT + GILEAD + AXIS2 POJO PROBLEM

2011-02-03 Thread Stefan Ollinger

Hi Daniele,

this seems to be a similar problem like before. Hibernate puts a proxy
around your objects, so your domain objects have hibernate-specific
properties. Axis2 has problems serializing them. You can configure Axis2
appropriately.

See this link for a more detailled explanation:

How to remove the check of the findxxx() static method in domain entity

2011-02-03 Thread Patrice De Saint Steban

Hello,

We use the request factory with spring and classic services, and for find a 
new entity, we use a method in the service and not in the domain entity.
We create a ServiceLayerDecorator to override the loadDomainObject to load 
the object without use the static method findxxx() in the entity.
It's works fine, put we must put a fake findxxx() static method for pass the 
validation. We try to override the RequestFactoryInterfaceValidator for 
remove the check findxxx() in the method checkIdAndVersion(), but it's not 
works.
Is there an another way to remove the check of the findxx() static method 
without define a fake method ?

Thanks

Re: local script variables in nocache.js

Re: GWT debuggin in Chrome - why is so slow?

2011-02-03 Thread Edson Richter

I'm working with the following environment:

a) Windows 7 Home Premium 64bit
b) Sun Java JDK 1.6.0_22 32bit and JRockit 4 (1.6.0_20) 32bit
c) NetBeans 6.9.2 on Sun JDK 1.6.0_22 32bit
d) Apache Tomcat 6.0.30 on Sun JDK 1.6.0_22 or JRockit 1.6.0.20 (both
32bit)
e) Front-end Google Chrome (8.0.552.237) with latest GWT plugin
(1.0.9646) or Mozilla FireFox (3.6.13) with latest plugin (1.0.9639)
f) NetBeans has the Nb4GWT plugin, so I can start the application in
debug mode so it starts Apache Tomcat in Debug Mode, opens the GWT
console and launch the application with url like
http://localhost:8080/SimuladorFrete/index.jsp?gwt.codesvr=127.0.0.1:9997

It works fine with FireFox, but Google Chrome never opens the page
when the data amount received from RPC service is really huge (4 or
5Mb of data through the network): it never hits the breakpoints marked
in the VM, it just never hit the onSuccess or onFailure, and keeps
giving the infamous The script in the page is too slow, continue
processing? (or similar message like this).

By today (using Apache+SunJDK), I got another error in the GWT Console
(may be thanks to the new plugin installed yesterday) - 4 stack traces
below:

Hi, Chris!

Thanks for your answer - even if I hit the Ignore or Continue
button (I don't remember the exact text appears in the button face,
because I do use Portuguese Brazilian here...), Chrome fronzen until
it dies with the Crash page.

The NPObject error did not happen since latest plugin. If I hit it
again, I'll open another thread.

Edson.

In Chrome, if I don't get NPObject... bug, then I get repeated

My application is a business application that uses several custom

Can anyone help me? Is there any Chrome configuration or restriction?
Is the plugin working in Chrome for debug mode?

I'll appreciate your help.

how can i implement Focusable (and HasAllKeyHandlers) on a TabLayoutPanel?

2011-02-03 Thread chm124

how can i implement Focusable (and HasAllKeyHandlers) on a
TabLayoutPanel?

Hi
In my App, the outermost Panel is a TabLayoutPanel (which must be
attached to RootPanel via RootPanel.get().add(TabLayoutPanel)),
otherwise its tab-contents are invisible.
I would like to implement my outermost Panel Focusable and at least
HasAllKeyHandlers, too,
since it should be possible to trigger KeyDown-events without explicit
clicking on the panel before it can handle the KeyDown-events.

In a first prototype, we used a TabPanel wrapped by a FocusPanel
(which implements Focusable and many other HasHandler_interfaces).
Now, for several reasons we MUST use TabLayoutPanel as outermost
panel.
Has somebody already done that or could give me a good hint to do
that?

Thanks in advance,
greez,
Christoph

Re: How to add datetimepiker in GWT

2011-02-03 Thread Jeff Schwartz

I haven't tested it but DatePicker's getValue method returns a Date object.
What I am not sure of is if the Date object reflects the current time when a
user selects a date from the calendar. The returned Date's getTime() method
needs to be tested to see if it does or doesn't.

Re: How to remove the check of the findxxx() static method in domain entity

 Hello,

You shouldn't do that (see below).
 

 It's works fine, put we must put a fake findxxx() static method for pass

 Is there an another way to remove the check of the findxx() static method

Use a Locator for your entities, and move your 
ServiceLayerDecorator#loadDomainObejct override within its find().

ActivityManager and TabLayoutPanel

2011-02-03 Thread Ernesto Reig

Hello everybody,
I don´t know if this problem can be solved easily or maybe I have to think
of another approach.
The thing is that I want a TabLayoutPanel, so that the ActivityManager keeps
track of all the activity´s of the different tabs, but the first problem I
find is setting the Display. The ActivityManager only accepts instances of
AcceptsOneWidget (activityManager.setDisplay(AcceptsOneWidget display);)
What can I do to implement this??

The second problem is that, providing that I finally have the
ActivityManager managing all the activities running within the context of
the TabLayoutPanel, what´s the best way to do this? I mean, is it better to
haver one View, one Place and one Activity per tab? How would you do it?

Thank you very much.

Re: Setting first column width CSS in CellBrowser via DOM API

2011-02-03 Thread John LaBanca

We haven't had a change to fix this yet.  CellBrowser uses a
SplitLayoutPanel that has a fairly complicated structure, so DOM
manipulation isn't likely to work.

As a workaround, you can get access to the SplitLayoutPanel in CellBrowser
and set the widget width directly.  Subclass CellBrowser and override
getWidget() to return a SplitLayoutPanel, then do the following:

SplitLayoutPanel splitPanel = cellBrowser.getWidget();
splitPanel.setWidgetSize(splitPanel.getWidget(0), 400.0);

Thanks,

 I raised query around a month ago about setting the width of the first
 column in a CellBrowser in GWT. There is a bug that stops this from
 occurring - it always displays with a default width of 200px because this is
 the generated HTML for the wrapper divs:

 div style=position: absolute; overflow: hidden; left: 0px; top: 0px;
 bottom: 0px; width: 200px;
 div style=position: absolute; overflow: hidden; left: 200px; top: 0px;
 bottom: 0px; width: 8px;

 My original post is here:
 https://groups.google.com/d/msg/google-web-toolkit/Zmz_1XDq4dI/R2LxcPQqNQ4J

 So as a work around I am trying to set the width style dynamically through
 the GWT DOM API. Here is some sample code showing my approach:

 Button test = new Button(Test);
 test.addClickHandler(new ClickHandler() {
 @Override
 public void onClick(ClickEvent event) {
 Element browserElement = browser.getElement();
  NodeList browserChildNodes = browserElement.getChildNodes();

 for (int i=0; ibrowserChildNodes.getLength(); i++) {
  Node n = browserChildNodes.getItem(i);
 int divCount = 0;
 if (n.getNodeType() == Node.ELEMENT_NODE) {
  Element e = Element.as(n);
 if (e.getTagName().equalsIgnoreCase(DIV)) {
 System.out.println(Before mod:  + e.getAttribute(style));
  if (divCount == 2) {
 Style s = e.getStyle();
 e.setId(col1);
  s.setWidth(400.00, Unit.PX);
 e.setAttribute(style, position: absolute; overflow: hidden; left: 0px;
 top: 0px; bottom: 0px; width: 400px;);
  } else if (divCount == 3) {
 e.setId(col1Dragger);
 e.setAttribute(style, position: absolute; overflow: hidden; left: 400px;
 top: 0px; bottom: 0px; width: 8px;);
  }
  System.out.println(After mod:  + e.getAttribute(style));
  divCount++;
 }
 }
 }
  }
 });

 However, when 'button Test is clicked, it makes no difference to the style
 attribute. The 'after mod' println shows the same results as 'before mod'.
 Checking the HTML, also shows no change.'  I have also tried the above code
 in the initialization code for the CellBrowser; nothing changes in the
 rendered HTML.

 I am sure I am looking at the right divs, as a println of the style
 attibute matches perfectly.

 setId(), also has no effect.

 I have also tried e.getStyle().setProperty(width, Unit.PX), and this had
 no effect.

 Why is the DOM manipulation having no effect?

GWT CellTable: very confused about T and C in ColumnT,C and HasCellT,C

I am very confused about HasCellT,C and ColumnT,C.

I am using Cell types available by GWT (TextCell, ActionCell etc), and I can 
get them to work.

However, when I try to create custom Cell for CellTable,
I realize I do not fully understand what I'm doing,
and the confusion is from not fully understanding difference between C and 
T.


could you please explain T and C, in context of having a CellTable,
displaying a Contact object ?
Contact is T or C ? and if its C then what is T and vice versa ?


Thank You 

in ColumnT,C
 * @param T the row type
 * @param C the column type

in HasCellT,C
 * @param T the underlying data type
 * @param C the cell data type

(do not fully understand difference between T and C, very confused,
what is T ? what is C ?)

Re: ActivityManager and TabLayoutPanel

2011-02-03 Thread Jack

Well I am not very familiar with the GWT MVP Framework but from what
I've read I would use one Place and one Activity for the whole
TabLayoutPanel an put it into a display region ( =
AcceptsOneWidget). I guess that should be fine in most situations.
For example a GWT application may have a place where the user can
change his personal preferences. These preferences could be
categorized into a couple of categories. This should be typical use
case for a TabLayoutPanel. So I would create a SettingsPlaces and a
SettingsActivity. The SettingsActivity would then put its view (a
complete TabLayoutPanel) into the AcceptsOnWidget provided in the
activities start method.
To determine the tab that should be shown I would use the place token,
e.g. http://yourapp/#SettingsPlace:t=tabindex.

Maybe I missed something because I am not a GWT MVP expert but I
hope it helps. In my opinion, having a separate ActivityManager for a
TabLayoutPanel is a bit overkill. If I am wrong, someone please
correct me :) I am also interested in how TabLayoutPanels should be
used with the GWT MVP Framework.

Why do you want to use a TabLayoutPanel and why do you think you need
an activity/place per tab?

Re: GWT CellTable: very confused about T and C in ColumnT,C and HasCellT,C

2011-02-03 Thread Jack

When using a CellTable that displays contacts you may have a column
that displays the name for each contact.
Thus this column would be defined as

ColumnContact, String implements HasCellContact, String

So T is the type of objects you want to display (the rows, e.g.
Contact, Car, ...) and C is the type of the property of T that will be
shown in a specific column (e.g. the contacts name (=String), the
contacts birthday (=Date))

So C and T have the same meaning in Column and HasCell.

History.replaceItem?

2011-02-03 Thread Jason

Before I start, I'm working with GWT 2.1.1

In the example below the user goes to a list, pages through results,
views a record and then clicks Back.  Everything works as expected,
the user is viewing page 4, clicks a row and views the record, clicks
Back and they land on page 4.  But if they click Back again, it goes
to page 3, then page 2, etc.

1. User is on the home page - History.newItem( HOME, true )
2. User selects list of records page - History.newItem( LIST, true )
3. User pages through results page (using CellTable) -
History.newItem( LIST#page2, false )
4. User pages through results page - History.newItem( LIST#page3,
false )
5. User pages through results page - History.newItem( LIST#page4,
false )
6. User selects record to view - History.newItem( VIEW#record123,
true )
7. User clicks Back, token is replaced with LIST#page4
8. User clicks Back, token is replaced with LIST#page3
9. User clicks Back, token is replaced with LIST#page2
10. User clicks Back, token is replaced with LIST

What I'd prefer to see is that when the press back from the record
page, it goes to the list page they were viewing and if they click
back again, it moves back to the home page.  So far I've worked around
this by adding a 'Close' button to the list page that is moves them to
the home page directly.

This would be easy if I could call 'replaceItem( TOKEN, false )'
instead of 'newItem( TOKEN, false )' in steps 2 through 5 above.  This
call would replace the current URL in the browser, and rewrite the
last entry in the history stack with the new entry.

Anyone else have this issue?

Re: How to get id of the new inserted row, issued by RequestFactory persist()

2011-02-03 Thread Dominik Mayer

Does anyone have answers to these questions? What I'm doing is
listening for an EntityProxyChange PERSIST. But that only has the
ProxyId so I have to do a

request.find(proxyId).fire()

in order to get the task. The problem is: This causes an
EntityProxyChange UPDATE which again only has the ProxyId. So I have
to do another

request.find(proxyId).fire()

This time with a Receiver that handles the task. I can't provide a
Receiver to the first request, because that would trigger the action
twice.

Re: History.replaceItem?

I have a possible alternative suggestion - instead of messing with the
browser's history function, simply don't use the history tokens for
navigating through the results list.  Then your back button will work
as you will want it to.

I do this in my application, and it seems to work quite well.

Re: Working with collection of entities in requestFactory

2011-02-03 Thread FrugoFrog

do you see the persistent elements in DB?  Can you see the elements if
you change  FetchType.LAZY to EAGER?


2011/2/2 JB jbthe...@gmail.com:
 Hi,

 I'm having troubles in using collection (list) of entities with
 requestFactory.

 The persistence of the whole graph is OK, but whenever I try to
 retrieve it, it shows no embedded element.

 There is obviously something wrong in my code, but I cannot figure
 out...
 I couldn't find any clear explanation nor a workaround.

 Here is my code:

 ---

 //class declaration
 public class Container{

        @OneToMany(fetch = FetchType.LAZY)
        private ListElement elements;
 }
 (getter/setters automatically generated with Roo)


 //creation
 ContainerRequest context = requestFactory.containerRequest();
 elementProxy element = context.create(ElementProxy.class);
 ContainerProxy container = context.create(ContainerProxy.class);

 ListElementProxy list = new ArrayListElementProxy();
 list.add(element);
 container.setId(foo);
 container.setElements(list);
 context.persist().using(container).fire();
 //so far, so good I got an Element created, and a container

 //retrieval
 ContainerRequest requestGetContainer =
 requestFactory.containerRequest();
 RequestContainerProxy getcontainer =
 requestGetContainer.findContainer(foo).with(elements);
 ReceiverContainerProxy callback = new ReceiverContainerProxy(){
        public void onSuccess(ContainerProxy result) {
                System.out.println(nb elements:  +
 result.getElements().size());
 }};
 callback.fire();

 ---
 as a result, the list of elements is empty

 Any help/tip welcomed on that.

You mean package private scope? The UiHandler methods may not be
private. I usually just make them public as I consider them to be part
of the page's/widgets API.

Re: Separate Widgets CSS+JS

2011-02-03 Thread Hilco Wijbenga

On 2 February 2011 16:17, Thomas Broyer t.bro...@gmail.com wrote:
 You can automate it by writing a linker that concatenates the CSS files into
 a single one (same for JS ?) and emit a new artifact for the all-in-one
 file.
 There's no built-in solution for that, because the script and stylesheet
 elements in gwt.xml files take URLs, not file paths; the URL can then just
 happen to match a file that's in a public path, but there's no relation
 between those apart from naming convention.

 ...but you could also use ClientBundle to have the CSS inlined in the
 compiled output (and make your widget take an instance of the bundle as
 constructor argument so you can easily override the default style; which in
 ClientBundle's world means the old, default CSS can be completely left out
 of the compiled output).

Excellent.

I've run into another issue, however. I'm now also including an image
in the widget JAR. The image is at org.example.public and I can access
it (in MyWidget's UiBinder) as src=MyWidget/my-image.png. However,
once I reuse the widget in another widget (say, OtherWidget) the image
is only found if I use OtherWidget/my-image.png.

I'm guessing there's a better way to do this?

How to implement Expandable-Collapsible Rows in CellTable ?

Hello Everyone,
Could you please provide some tips on how to implement Collapsible Rows in 
CellTable ?

for example, clicking on a Row, result in Row to be expanded, and display 
some custom widget in it.

so far, I was able to put a custom widget (label, button, text box) within 
the cell,
this works fine. I then wanted to show/hide this widget, as user clicked on 
the cell.

my custom cell handles click event, and adds/removes css style 
(display:none), as a result I can show/hide my custom widget,
but the problem is, since I am handling click event, when the user wants to 
do
something meaningful with the widget inside the row, the row is closed,
(for example entering something inside the textbox, causes the row to close 
(hide/collapse))
I used event.preventDefault(), to stop the click event from firing once the 
row is expanded (preventing it from hiding, so that user can enter text into 
textbox),
but cannot reverse it (remove it so that it can be closed).

 anyways I tried many many unconventional solutions, including putting a 
basic Tree and StackPanel inside a Custom Cell !
none of them worked  : (

I know that I am not doing things the right way,
do you have any tips on how to implement this feature ? 
Expandable/Collapsible Rows inside a CellTable ?

do you think this feature will be added in later releases of GWT ?

Thank You

Re: How to get id of the new inserted row, issued by RequestFactory persist()

2011-02-03 Thread Dominik Mayer

I found the answer here 
http://groups.google.com/group/google-web-toolkit/msg/fa25840137b26e72:

   InstanceRequestEmployeeProxy, EmployeeProxy persist();
 instead of
   InstanceRequestEmployeeProxy, Void persist();

But I'm still not sure I get the concept. If I use this way I can
access the persisted object in the onSuccess(...) method. But
EntityProxyChange UPDATE will fire *before* the Receiver gets the
result from the server.

I want to put the received task in a list and update a CellList. The
perfect way would be to put an add(Object) method in the Receiver and
some kind of setData() in EntityProxyChange UPDATE. But that won't
work because the data would be set *before* the persisted object has
been put in the list.

Its also not possible to move add(Object) to EntityProxyChange UPDATE
because you only have the ProxyId in there and would have to make
another request to the server in order to get the populated object.

Re: local script variables in nocache.js

2011-02-03 Thread Colin Alworth

In your *.nocache.js content, you say you will have 'this.resourceUrl = 
content-replaced-by-velocity;' – what is 'this' in this context? If it is 
the shared window that all the portlets use, they will each overwrite the 
resourceUrl property. If each portlet will use a different module, you could 
use modulename to set and access this data. This could look something like
window.MyModuleName.resourceUrl = $resourceUrl
and then access it in your native method with
return $wnd[@com.google.gwt.core.client.GWT::getModuleName()()].resourceUrl;


If I have misunderstood and each portlet is in its own iframe, then your 
native call just needs to say 'return $wnd.resourceUrl;' to correctly 
reference the window object that the resourceUrl was set in.

Hope this helps,
Colin

What is the correct way for CellTable cells to communicate ?

I have a CellTable.

when an event occurs in Cell A,
I would like to take action and modify Cell B.
(user clicks on Cell A, I would like to modify Cell B, in the same row to 
keep things simple)

could you please provide some pointers on how this can be correctly 
implemented ?

do you think we need to use DOM events or GWTEvents,
and do you think it has to be handled at Cell level, or Table level ?

any ideas are really appreciated.

How to create DOM Element or Node from SafeHtml

GWT has Element and Node class which are wrappers for low level DOM 
elements/nodes.

do you know How I can convert SafeHtml to Element or Node ?

for example using the code below, I create a SafeHtml.

SafeHtml html = 
SafeHtmlUtils.fromSafeConstant(trtdXXX/tdtdYYY/td/tr);

but I could not find a way to create a Node or Element from this SafeHtml.
I could manipulate existing Node/Elements but not create one.

I want to add a new row to an existing table using Element/Node class.
therefore I need to create a new row, not manipulate an existing row.

do you have any idea how this can be possible ?

Thank You

Re: How to create DOM Element or Node from SafeHtml

One solution is to clone an already existing node and then manipulating it.

1- clone an already existing node
eg. Node node = parent.cloneNode(false)

2- cast this Node to Element
eg. Element element = Element.as(node)

3- manipulate this element
eg. element.setInnerHTML(html.asString) // using the SafeHtml you provided 
in your post

[gwt-contrib] Re: Decouple JsProgram; this allows the JS AST to serialize in pieces. (issue1342801)

2011-02-03 Thread cromwellian



One thing I'll mention out of band, is that the changes that switch from
singletons created by JsProgram to instances seem to remove all of the
addCorrelator stuff. Honestly, I don't know what that stuff is used
for (SOYC?) but I wonder what the impact of removing it is.

JsName entryName = topScope.findExistingName($entry);
this is a change in semantics. In JsRootName, it forces identifiers to
be not-obfuscatable (sensible, since most of them aren't, except for the
GWT derived ones), but the patch forces $entry to be treated the same as
alert or getElementById.

Untrue, root names are not obfuscatable, but GWT derived ones (e.g.
$entry) may be. Stuff like addEventListener isn't.

[gwt-contrib] Re: Decouple JsProgram; this allows the JS AST to serialize in pieces. (issue1342801)


@zundel: if we did want flyweight literals, we could always manage them
at class level for the whole process rather than at the JsProgram level,
like Integer.valueOf() works.

@cromwellian: I'm not sure to what degree the source info correlations
are useful and important.  I guess my plan was to chip away at this and
see if anyone pushes back.  It's easy enough to re-add if people scream.

I'm just abusing JsCatchScope as a convenient, lightweight way to get a

Because the root scope is now immutable, and you're not allowed to write
into it.  It represents, essentially, browser built-ins.  The top
program scope represents your program.  It doesn't make a functional
difference where these unresolved names live, because they're... well..
unresolved and assumed to be external references.

Log: Fix CompilationStateBuilder's speed tracer logs.

Currently, CompilationStateBuilder produces a tree like:

Process
- Process

Where the top node has almost no time in it at all, and serves no purpose.   
This

jiggles things so you get a trace more like:

Process
- JdtCompile
- Process (many, smaller ones)

dev/core/src/com/google/gwt/dev/util/log/speedtracer/SpeedTracerLogger.java:477:
private final long zeroTimeMilliseconds;
will doalthough, it looks like it doesn't seem to really need the
baseTime afterall?  I tried commenting out the generation of the
baseTime data altogether, and it doesn't seem to affect things at all
(speedtracer seems to normalize the time just fine).   That and also for
the case of processCpuTime (which has no basis in wall time)...

http://gwt-code-reviews.appspot.com/1336803/diff/1/3#newcode592
dev/core/src/com/google/gwt/dev/util/log/speedtracer/SpeedTracerLogger.java:592:
Cummulative Collection Count,
Long.toString(gcMXBean.getCollectionCount()));
So, for visualization purposes here, it seems ok to leave as is, no?
