Getting started with Activities and Places.  I'd like to use a
DockLayoutPanel to comprise the entire view (page).  When I try, it
doesn't work.

Note I'm using HelloMVP is a starting point and that in the EntryPoint
a SimplePanel is set up as the default Panel.  I've tried adding a
DockLayoutPanel to that.  I also tried first adding a VerticalPanel
and then a DockLayoutPanel based on some suggestions here.

The DockLayoutPanel simply doesn't display.  This was also mentioned
in this message from last Oct: http://tinyurl.com/3z8mn4v.  The
resolution there was to adjust the positioning styles to be absolute.
However, they appear to already be absolute.

I've played around with setting the width and height of the parent
(SimplePanel) panel to 100%.  I've changed RootPanel to
RootLayoutPanel in onLoadModule.  Nothing seems to work.  Seems like
this would be something that is commonly done OR am I heading down the
wrong path?

Any ideas?
Mike

Re: Singleton instance in RPC AsynCall with two or more RPCs

Re: DataGrid on a hidden tab

2011-08-15 Thread P.G.Taboada

Well, not really, as I am not using lazy panels.

But that is not the point: the should get rendered once the tab gets
selected. To work around it, I did add the grid to a split panel in
the tab. Now I have to move the slider to make the grid appear. Ok, it
is not a workaround. ;)

Btw, split panels don't do whell on an iPad... ;)

Give DataStoreGwt a try. It does exactly what you require. It helps

Best/Correct way to attach events to an element

2011-08-15 Thread DaveC

Hi,

I've got some generated HTML that I'm trying to hook into using GWT to
listen to events. At the moment I've this:

public class LightWeightUiObject extends UIObject {

public LightWeightUiObject(Element element) {

setElement(element);

sinkEvents(Event.ONTOUCHSTART);
sinkEvents(Event.ONTOUCHMOVE);
sinkEvents(Event.ONTOUCHEND);
}

}

Is this the best/correct way of doing this?
(What I'm trying to do is avoid using Widgets as this dramtically
increases the size of my compiled app)

Cheers,
Dave

Access ServerFailure exception in RequestTransport ?

2011-08-15 Thread Mihail Lesikov

Hi,
In my aplicaiton I have loading bar that is managed with events via the 
event bus.
I'm using requestFactory framework.
When a request is sent, the loading bar should become visible, and when the 
response is received it should be hidden or if there is any system error it 
should be visualized as a specified message.
I have custom implementation of the RequestTransport :

public class AppRequestTransport extends DefaultRequestTransport {
...
// counts exactly how much requests are sent,
// if the response is received after the other request has been sent,
// the loading bar should not be hide
private int requestCounter = 0;
...

@Override
public void send(String payload, RequestTransport.TransportReceiver 
receiver) {
eventBus.fireEvent(new ShowLoadingBar(true));
requestCounter++;
}

...

@Override
protected RequestCallback createRequestCallback(final TransportReceiver 
receiver) {
return new RequestCallback() {

public void onError(Request request, Throwable exception) {

eventBus.fireEvent(new ShowLoadingBar(true, System Error));

receiver.onTransportFailure(new ServerFailure(exception.getMessage()));

requestCounter = 0;

}

public void onResponseReceived(Request request, Response response) {
try {
if (Response.SC_UNAUTHORIZED == response.getStatusCode()) {

String message = UNAUTORIZED USER +   + response.getStatusCode();

eventBus.fireEvent(new ShowLoginDialogEvent());

receiver.onTransportFailure(new ServerFailure(message, null, null, false));

requestCounter = 0;

} else if (Response.SC_OK == response.getStatusCode()) {

String text = response.getText();

// HERE I can't understand what is actually the result of server i there an 
Exception thrown or a
// proper result. That information is available in the Receiver. I need to 
know that here, because if there is an unexpected exception thrown
//from the server it is converted to a ServerFailure object and is passed to 
the Receiver, so I have every time to check exactly what
//server failure I receive.

receiver.onTransportSuccess(text);

} else {

String message = SERVER_ERROR +   + response.getStatusCode() +  + 
response.getText();
receiver.onTransportFailure(new ServerFailure(message));

requestCounter = 0;
}
} finally {
hideLoadingBar();
}

}
};
}

private void hideLoadingBar() {
requestCounter--;
if (requestCounter = 0) {
requestCounter = 0;
eventBus.fireEvent(new LoadingBarEvent(false));
}
}

I have and my own wrapper of the Receiver class:

public abstract class MyReceiverZ extends ReceiverZ {
private EventBus eventBus;

public MyReceiver(EventBus eventBus){

// paseing the event bus every time to the constructor of the Receiver
this.eventBus = eventbus;
}
...
@Override
public void onFailure(ServerFailure error) {

if (eventBus != null) {
handleError(error);
}

if (error.isFatal()) {
GWT.log(ServerFailure:  + error.getStackTraceString());
super.onFailure(error);
}
}

}

Is there a way to handle the result of the request in the RequestContext, so 
I could manage the loading bar only form there?
If there is no way in the RequestTrasport, is there any other place?

Dynamically editing list of ValueProxies with ListEditor

2011-08-15 Thread Mihail Lesikov

I have a list of phoneNumbers(ValueProxy) for a specified contact that I 
need to edit dynamically(add new/remove/change) using ListEditor.

When I try to remove one of the phoneNumbers :

listEditor.getList().remove(phoneNumber); // phone number is the last proxy 
in the list

1) as a result, the first element in the list is always removed
2) when flush is called on the contactEditor(parent editor that contacs the 
driver), no values are filled in the list of phoneNumbersProxies

Other thing that i noticed is that every valueProxy.hashCode() is the same 
as others from that type.

Re: Activities and Places and Layouts (again)

You need rootlayoutpanel, the host page should be in standards mode

Then you should look if all the panels being used implement provides

Eclipse, Maven, GWT: Multiple modules in a single Eclipse project

2011-08-15 Thread Mike

Hi, we have an existing web application (JSF, Seam on JBoss) and are
reimplementing portions of it in GWT.  These portions will be separate
GWT modules, each with their own entry point.  The application is
currently a single Eclipse project with Maven handling dependency
management and the GWT compile (gwt-maven-plugin).  We have a couple
GWT modules implemented so far and have had little trouble getting all
the different tools working together.

Now, we are looking to set up another, no entry-point, module from
which all the other modules will inherit.  This modules will hold
shared code and resources.  Ideally, we would like this shared module
to be in the same project.  So far, our attempts to set up such a
module have been fruitless.  GWT compiles do not produce artifacts for
the shared module or any for modules that inherit from it.  Also, dev
mode will not load the JS file for any module that inherits from the
shared module.  It seems like the approach we are taking would be
relatively common, so I am assuming we have not set up the project
correctly.  Does anyone have any insights or know of any resources
that would be helpful?  Thanks.

Re: Activities and Places and Layouts (again)

I replaced RootPanel with RootLayoutPanel.

Here is the EntryPoint from HelloMVP:

 private SimplePanel appWidget = new SimplePanel();
 ...
 RootPanel.get().add( appWidget );
 activityManager.setDisplay( appWidget );

I replaced RootPanel with RootLayoutPanel:

 private SimplePanel appWidget = new SimplePanel();
 ...
 RootLayoutPanel.get().add( appWidget );
 activityManager.setDisplay( appWidget );

Maybe I'm a little too naive in thinking that would do much.

Also, when I look at the page source generated, it appears a DOCTYPE
is already there.  Here is the page source generated by the GWT app
(HelloMVP).

 !doctype html
 !-- The DOCTYPE declaration above will set the--
 !-- browser's rendering engine into   --
 !-- Standards Mode. Replacing this declaration  --
 !-- with a Quirks Mode doctype may lead to some --
 !-- differences in layout.--

If I create a simple GWT app (not Activities  Places) and plop a
DockLayoutPanel in the RootPanel, it just works.  Fills the page
nicely without having to add any onResize handlers.  Is there a reason
why adding handlers would be needed in an Activities  Places
framework (such as that provided by HelloMVP)?  I'd like to understand
that a bit more.

second level domains and cross-site scripting vulnerabilities:

http://en.wikipedia.org/wiki/Comet_%28programming%29

Not familiar with Websockets.

What I want to do is this: have my servlet push data to my user
interface widget reusing the HTTP connection.  Not sure what version
of Jetty is used in GWT 2.3 (ultimate goal is to deploy on Tomcat 6,
but, wanted to get something working in the hosted environment
first).

From your response, sounds like this is controlled from the servlet
code and not Jetty.
Will you point me to an example?

Many thanks,
Gator Bait

 part of the servlet you're connecting to.  Websockets will require aJetty7

  Hi,

  I'm new to GWT.

  I'm using GWT 2.3 and the embeddedJettyserver instance(not sure what

  Will someone point me to an example of howJettyshould be configured

Re: Eclipse, Maven, GWT: Multiple modules in a single Eclipse project

2011-08-15 Thread Mike

As always, the answer becomes apparently minutes after asking the
question:  it turns out you need to explicitly list your modules in
the pom file's configuration of the gwt-maven-plugin plugin.  This
allows you to specify an order, ensuring that the shared module is
compiled first.

On Aug 15, 10:07 am, Mike mreynolds0...@gmail.com wrote:
 Hi, we have an existing web application (JSF, Seam on JBoss) and are
 reimplementing portions of it in GWT.  These portions will be separate
 GWT modules, each with their own entry point.  The application is
 currently a single Eclipse project with Maven handling dependency
 management and the GWT compile (gwt-maven-plugin).  We have a couple
 GWT modules implemented so far and have had little trouble getting all
 the different tools working together.

 Now, we are looking to set up another, no entry-point, module from
 which all the other modules will inherit.  This modules will hold
 shared code and resources.  Ideally, we would like this shared module
 to be in the same project.  So far, our attempts to set up such a
 module have been fruitless.  GWT compiles do not produce artifacts for
 the shared module or any for modules that inherit from it.  Also, dev
 mode will not load the JS file for any module that inherits from the
 shared module.  It seems like the approach we are taking would be
 relatively common, so I am assuming we have not set up the project
 correctly.  Does anyone have any insights or know of any resources
 that would be helpful?  Thanks.

Aw: Re: Activities and Places and Layouts (again)

2011-08-15 Thread Jens

I think you should use 

SimpleLayoutPanel appWidget = new SimpleLayoutPanel();
RootLayoutPanel.get().add(appWidget);

Now you should be able to add a DockLayoutPanel to the appWidget inside an 
activities start method.

But do you really want a DockLayoutPanel just for one Place/Activity or do 
you want a DockLayoutPanel thats always present and you want to change the 
center area based on the current place (and use west for a menu or 
something)? If so you should do something like:

DockLayoutPanel appFrame = new DockLayoutPanel();
SimpleLayoutPanel content = new SimpleLayoutPanel();
//FlowPanel menu = new FlowPanel();
//menu.add(new HyperLink(abc));
//appFrame.addWest(menu);
appFrame.add(content)
RootLayoutPanel.get().add(appFrame);
activityManager.setDisplay(content);

Re: CellTable custom footer

 Hi Everyone,

 I'm trying to add a footer to my CellTable and am having a hard time
 finding information on creating a footer that would update dynamically
 based on the cells in that column.

 i.e. I want the last row in my cell table to have a total footer.

 Adding static text is easy as you just pass an extra argument to the
 constructor:
        cellTable.addColumn(qty, Qty,Integer.toString(totalQty));

 Thats not what want though.

 If i don't set totalQty to a value before adding the column to the
 CellTable then it shows up as 0. If i try using the funtion
 CellTable.redrawFooters() it does not update the footer with the
 updated variable value for totalQty.

 I see in the documentation that footers are supposed to update
 automatically when set up as a type Header.

 I can' t find any source examples so if anyone could point me in the
 right direction or post an example that would be great.

 Thanks,
 -Mark

Number Of Permutations Question

2011-08-15 Thread Alfredo Quiroga-Villamil

Hello group:

Prior to GWT 2.3.0 I was able to limit the number of permutations generated
by GWT by specifying the property user.agent. The generated JS had no
references in it to the actual agent or anything related to it. When I use
GWT 2.3.0 now to compile I see a few lines in the generated JS that
reference User Agent. For example:

= Generated JS output in pretty mode =

function $getRuntimeValue(){

  var ua = navigator.userAgent.toLowerCase();

 ...

= Generated JS output in pretty mode =

I would like to use GWT to compile the Java code to JS and have it so that:

1. It only generates one version of the JS with no references to a browser
in this case. It worked like that prior to GWT 2.3.0.

2. Furthermore I would like to also be able to use Constants and not have
multiple permutations but just one.

I've for now found a way to accomplish number 2 I think by modifying the
I18N.gwt.xml default value for the locale and setting it to the one I want.

Can someone recommend a way if possible to use GWT to compile to JS with
just one permutation in GWT 2.3.0 without generating references to the UA in
the generated JS?

Thank you in advance for the help.

Re: Number Of Permutations Question

2011-08-15 Thread Alfredo Quiroga-Villamil

Hi Magno, appreciate the response.

Yes looking for a way to remove that check at run time if possible. It
didn't do that prior to GWT 2.3.0. I've checked the generated JS and it
starts to do that after 2.3.0.

Regarding constants, I can't do what you are suggesting because it'll do
more than one permutation if I do it in my file. The only way I've found to
really force it is to just do it out of I18N.gwt.xml. If I do it in my
x.gwt.xml file it does the locale I specify and the default as well (2
permutations). So I need to limit it to just one permutation.

Ideas and any help are really appreciated.

Thank you,

Alfredo

 I don't know why, but GWT check for the user agent at runtime to assert it

 you can change that.

 Regarding i18n, afaik you can restrict the number of locales on your
 *.gwt.xml file as you did for user agent, there's no need to edit gwt's
 I18N.gwt.xml file

 Hi,

 I have have a celllist in a UIBinder,  when I use JSON to get some

 about 20 seconds), This problem does not seems to happen if I get the
 data any other way i.e. load it from code rather that remote server.

 I have tried to cut the code down as small as possiable, (statusText
 is a label on screen).
 I can see that statusText stays Set Data so I know the results have
 been returned back, but the screen does not update.

 -
 initWidget(uiBinder.createAndBindUi(this));

 statusText.setText(Getting results);

 TaskFactory taskFactory = new TaskFactory();
 taskFactory.GetTasks(new AsyncCallbackArrayListTaskModel() {

 @Override
 public void onFailure(Throwable caught) {}

 @Override
 public void onSuccess(ArrayListTaskModel result) {
 cellList.setRowData(result);
 statusText.setText(Set Data);

 }});

 

 Taskfactory in the code is based on the JSONP code that is the main
 GWT page, I can put the debugger on the line and see that the array
 returned contains all the data I expect

 Any ideas?

 Cheers

Re: GWT 508 - Alternative text on gwt-tree expand/collapse image

2011-08-15 Thread andrew

Running into the same kinds of issues almost a year after this post (using 
GWT 2.0.4)...
Need to set alt text and need to discern both tree selection and hierarchy 
with CSS turned off. 

This can be made more elegant but here is the strategy (some GWT Tree 
assumptions are made here)...
We are adding and OpenHandler and CloseHandler to the Tree. 
Each handler checks if the TreeItem has children then it has an expand or 
collapse (+/-) child image (may want to consider whether or not you have 
leaf images).

For each TreeItem with children,  item, whose img alt or title attributes 
you want to set, access its img tags:
NodeListcom.google.gwt.dom.client.Element imgs =  
item.getElement().getElementsByTagName(img);

access the first Element in this set because this is the +/- img and set the 
attributes you want:
com.google.gwt.dom.client.Element elem = imgs.getItem(0);
elem.setAttribute(alt, ...);
elem.setAttribute(title, ...);

Our selected strategy is to append to the beginning of the selected 
TreeItem's text a selected character (ex. right-facing triangle). 

Still working on a solution to showing tree depth with CSS off.

Re: Activities and Places and Layouts (again)

Jens,

I am doing as you suggest.  onModuleLoad() creates the SimplePanel and
the View implementation adds a DockLayoutPanel.  Basically, I copied
the HelloMVP example.

You bring up an interesting issue.  Do I really want a DockLayoutPanel
for just one activity/place.

In this case I do.  I would think that this is a common thing to do,
particularly for mobile apps because of the small screens.  I believe
Activities  Places comes from Android.

What I really want is an app with say 3 places, let's call them A, B,
and C.  Each place is associated with its own activity and presenter
and view.  A's view could have a DockLayoutPanel, B's could have a
Tabbed panel, and C could have something else.  I would expect the
presenter would handle all events in each place/view.

Think of an online store, for example.  A could be the search for
items, B could be the checkout cart, and C could be user account
settings.  All completely different places with completely different
page layouts.

Mike

 I think you should use

 SimpleLayoutPanel appWidget = new SimpleLayoutPanel();
 RootLayoutPanel.get().add(appWidget);

 Now you should be able to add a DockLayoutPanel to the appWidget inside an
 activities start method.

 But do you really want a DockLayoutPanel just for one Place/Activity or do
 you want a DockLayoutPanel thats always present and you want to change the
 center area based on the current place (and use west for a menu or
 something)? If so you should do something like:

 DockLayoutPanel appFrame = new DockLayoutPanel();
 SimpleLayoutPanel content = new SimpleLayoutPanel();
 //FlowPanel menu = new FlowPanel();
 //menu.add(new HyperLink(abc));
 //appFrame.addWest(menu);
 appFrame.add(content)
 RootLayoutPanel.get().add(appFrame);
 activityManager.setDisplay(content);

Re: Activities and Places and Layouts (again)

Dave,

I never thought about adding the DockLayout in the activity's start()
method.  I am using the HelloMVP sample and they add widgets to the
view in the view's implementation (HelloViewImpl).

When the activity (associated with the view) is activated (at a later
point), HelloViewImpl creates its view (adding widgets).  I simply
added a DockLayoutPanel and called initWidget() in the view's
constructor.  I believe that sets the SimplePanel's child to the
DockLayoutPanel.

I can see evidence of a DockLayoutPanel in Firebug.  I can see the DIV
tags with the text of the labels I put in each position (north, south,
etc).  However, on the page I only see the north cell.  I've set the
SimplePanel's width/height to 100% as well as the DockLayoutPanel's
width and height to 100%.

Thanks,
Mike

The DockLayoutPanel simply doesn't display.  This was also mentioned

event.getKeyCode not returning correct for key up event

2011-08-15 Thread SG

I am running GWT 2.3 in Standards mode and ran into this issue where
the getKeyCode method on the Event(com.google.gwt.user.client.Event)
object does not return correct values for special characters and also
those for letters seem to be inverted i.e. if I type 'S' I am getting
the code for 's' and vice versa. Any pointers on whats going on and
what I can do to fix. Below is a snippet of code that I am trying to
execute

Event event = DOM.eventGetCurrentEvent(); /* Note I do not have access
to the actual KeyUpEvent, so I need to use this */
char keyUpChar = (char)event.getKeyCode();  /* This returns 57 for the
'(' char which should be 40 and 83 for 's' which should be 115

Thanks!

Getting started with Activities and Places.  I'd like to use a

Note I'm using HelloMVP is a starting point and that in the EntryPoint
a SimplePanel is set up as the default Panel.  I've tried adding a
DockLayoutPanel to that.  I also tried first adding a VerticalPanel
and then a DockLayoutPanel based on some suggestions here.

The DockLayoutPanel simply doesn't display.  This was also mentioned
in this message from last Oct:http://tinyurl.com/3z8mn4v.  The
resolution there was to adjust the positioning styles to be absolute.
However, they appear to already be absolute.

I've played around with setting the width and height of the parent
(SimplePanel) panel to 100%.  I've changed RootPanel to
RootLayoutPanel in onLoadModule.  Nothing seems to work.  Seems like
this would be something that is commonly done OR am I heading down the
wrong path?

Any ideas?

Using normal Panels and LayoutPanels

2011-08-15 Thread Foermchen82

Hi all,

I want to use the DataGrid of GWT 2.4. But this I have to add to the
RootLayoutPanel.

For a specific layout with other panels I have to use f.e. the
DockLayoutPanel.
But to add Widget to the DockLayoutPanel, I have to apecify the size:

DockLayoutPanel mainPanel = new DockLayoutPanel(Unit.PX);
Label newLabel = new Label(Hallo);
mainPanel.addNorth(newLabel, 100);
mainPanel.add(new DataGrid();
RootLayoutPanel.get().add(mainPanel);

How can I set the size of the north-part only to the required space?
There is no getWitdh() on the Label.

Is there any other way to use the DataGrid on the RootPanel instead of
the RootLayoutPanel?

Re: CellTable custom footer

2011-08-15 Thread John LaBanca

If you pass a Header instance as the footer, it will be updated every time
you push new row data.  You can also refresh footers manually using
CellTable#redrawFooters().

There is also a pending change that allows you to fully customize headers
and footers:

Re: Number Of Permutations Question

2011-08-15 Thread Alfredo Quiroga-Villamil

Hello group:

I was able to find the solution for the runtime JS that was being generated.
I was able to remove the runtime JS code by adding:

 inherits name=com.google.gwt.user.UserAgent /
set-configuration-property name=user.agent.runtimeWarning value=false/

Hope this helps someone in the future.

 Hello group:

 Prior to GWT 2.3.0 I was able to limit the number of permutations generated
 by GWT by specifying the property user.agent. The generated JS had no
 references in it to the actual agent or anything related to it. When I use
 GWT 2.3.0 now to compile I see a few lines in the generated JS that
 reference User Agent. For example:

 = Generated JS output in pretty mode =

 function $getRuntimeValue(){

   var ua = navigator.userAgent.toLowerCase();

  ...

 = Generated JS output in pretty mode =

 I would like to use GWT to compile the Java code to JS and have it so that:

 1. It only generates one version of the JS with no references to a browser
 in this case. It worked like that prior to GWT 2.3.0.

 2. Furthermore I would like to also be able to use Constants and not have
 multiple permutations but just one.

 I've for now found a way to accomplish number 2 I think by modifying the
 I18N.gwt.xml default value for the locale and setting it to the one I want.

 Can someone recommend a way if possible to use GWT to compile to JS with
 just one permutation in GWT 2.3.0 without generating references to the UA in
 the generated JS?

 Thank you in advance for the help.

SuggestBox popup Z-Index issue (appears behind everything)

2011-08-15 Thread darkflame

It seems this issue is still present;
http://code.google.com/p/google-web-toolkit/issues/detail?id=1351

Using a SuggestBox in a composite which has had a zIndex value set
means the popup of the suggestions appears behind everything else.
(no Index seems to be set at all on the popup).

So I either need a way to set the suggestions popup index, or some way
to trigger the suggestion box in a way for it to do it automaticaly.
(its being triggered after the composites z-Index is set at the
moment).

Re: display file icon in GWT grid

2011-08-15 Thread Thad

You can write a servlet that gets the icon and returns it as a PNG.
Call that servlet as the Image url (vs using AbstractImagePrototype).

Warnings: (1) this will make a servlet call for each icon you load in
the grid; (2) if JFileChooser.getIcon() needs a DISPLAY, your call may
not succeed. That depends on if the servlet engine has access to the
display (fairly certain on Windows, Mac, and some Linux, but if the
server is running headless or if the servlet engine's user lacks the
permissions, it will fail).

One of the SuggestBox constructors lets you pass in a custom

Re: Embed pdf into gwt app

2011-08-15 Thread karim duran

Hi Papick,

In my opinion, the problem is not about your iframe or any GWT container.
Concerning object or embed, i think you should use the standard way
provided by W3C specifications e.g object.

GWT provides cross-browser support for rendering. But don't process
media-type rendering.

Remember that if your browser can find a plugin to display a media-type (PDF
in your case), the media-type will display in your browser as you expect.

If your browser can't find a plugin, it calls the system default application
for this media-type ( Adobe Reader for exemple in your case with PDF ).

But, from the point of view of the user of your application, *you don't have
any control on how his browser will behave*. I mean that when the user
browser meet the object tag, it can display the PDF as you expect because
the Adobe Reader plugin is on the user system; Or it can call the Adobe
Reader desktop application because the plugin is not available for his
browser.

In firefox, you can force the behavior for a media-type. Go to - preference
- application, and search PDF document. You can see many actions the
browser can provide. You can choose the one interesting you.

to know about installed plugins for your browser, just type url
about:plugins.

Regards.

Karim Duran

 hello,

 I am tryring to display PDF files in my app. Unfortunately, Firefox
 and Safari are downloading the PDF instead of showing them embedded.

 I tried object and embed and an iframe element, the PDF always
 gets downloaded. When using embed or object it even messes with the
 history, the app get thrown back in history (I am using Places/MVP).

 Did anyone succeed in showing a PDF?

 Hi Papick,

 In my opinion, the problem is not about your iframe or any GWT container.
 Concerning object or embed, i think you should use the standard way
 provided by W3C specifications e.g object.

 GWT provides cross-browser support for rendering. But don't process
 media-type rendering.

 Remember that if your browser can find a plugin to display a media-type
 (PDF in your case), the media-type will display in your browser as you
 expect.

 If your browser can't find a plugin, it calls the system default
 application for this media-type ( Adobe Reader for exemple in your case with
 PDF ).

 But, from the point of view of the user of your application, *you don't
 have any control on how his browser will behave*. I mean that when the
 user browser meet the object tag, it can display the PDF as you expect
 because the Adobe Reader plugin is on the user system; Or it can call the
 Adobe Reader desktop application because the plugin is not available for his
 browser.

 In firefox, you can force the behavior for a media-type. Go to -
 preference - application, and search PDF document. You can see many actions
 the browser can provide. You can choose the one interesting you.

 to know about installed plugins for your browser, just type url
 about:plugins.

 Regards.

 hello,

 I am tryring to display PDF files in my app. Unfortunately, Firefox
 and Safari are downloading the PDF instead of showing them embedded.

 I tried object and embed and an iframe element, the PDF always
 gets downloaded. When using embed or object it even messes with the
 history, the app get thrown back in history (I am using Places/MVP).

 Did anyone succeed in showing a PDF?

 Brgds,

 Papick

Re: Focus bug with TabLayoutPanel?

2011-08-15 Thread camerojo

There is a workaround - which is to defer the setFocus call:

ie
Scheduler.get().scheduleDeferred(new Scheduler.ScheduledCommand()
{
  public void execute() {
name.setFocus(true);
  }
});


Clearly this is some kind of timing problem.

Re: HTTP Persistent Connection in Jetty

2011-08-15 Thread Kevin Jordan

Well, Comet is a pretty broad term that includes what you want.
Although you can't keep a connection alive forever, unless you use the
hidden iframe technique from your wikipedia link, which is where the
vulnerability comes in. At the moment, you can use Jetty
Continuations or Servlet 3 to achieve long polling through request
suspending.

Via continuations:
final Continuation continuation =
ContinuationSupport.getContinuation(request);
continuation.setTimeout(35000);
continuation.suspend(response);
//Do processing
continuation.resume();

See more at:
http://download.eclipse.org/jetty/stable-7/apidocs/org/eclipse/jetty/continuation/Continuation.html

Servlet 3 has a similar API, you suspend and resume or complete the
request:

Hi Kevin,

Didn't think Comet was a good choice because of issues regarding
second level domains and cross-site scripting vulnerabilities:

Not familiar with Websockets.

What I want to do is this: have my servlet push data to my user

of Jetty is used in GWT 2.3 (ultimate goal is to deploy on Tomcat 6,

From your response, sounds like this is controlled from the servlet

Will you point me to an example?

GWT CellTable row height

2011-08-15 Thread Ashok

Hi,

 I'm developing an application using GWT. I'm using celltable to
display dynamic values from database (based on a query). I have
following queries:

Assume: I have set the table height as 100px. I have placed the table
in a scrollpanel.

1. Now, My query returns 20rows, which are more than 100px, I want the
table to resize to fit all the 20rows. which inturn would cause the
scrollpanel to resize, which inturn should resize the parent of the
scrollpanel. First of all, I would like to know if this is possible at
all? If so, how?

I have tried these:
 I thought, by obtaining the tables new and old height, I could resize
by calling setHeight() and for the parent's height, by
getParent().setHeight(). However, I was stupid to think this way as
I'm setting the value of the height for the table to be 100px. As this
is static, it would print the same value for old and new height and
would change nothing.

Any ideas of how to proceed with this??

Re: log in tomcat with gwt - j_security_check limitation

2011-08-15 Thread Vitrums

I found this solution very handy. At least it suits my needs quite well. But 
still there's an issue with login.jsp, which might also produce an 
authentication interface for admin tools as an example. And the point is, 
that while an ordinary user gets everything what he needs, some manager with 
sysadmin role will also get this UI for login, which is not correct. And 
it can't be avoided by standard means of tomcat due to the fact, that only 
one login.jsp instance is allowed. And the DTD of web.xml doesn't support 
mapping of url specific context with different login pages =( E.g. there 
easily could be two secure1 and secure2 sections and they've got 
different access constrictions.

Actually I spent a couple of hours to figure out if I can distinguish which 
end-point url was requested within login.jsp code. And I wasn't successful 
to obtain any mean to do that. Wounder why this option is not supported by 
tomcat. Hence one probably may want to recompile tomcat with few additions 
in security code to do one of the following:
1. Whether allow web.xml to have more than one login-config element and 
make it parsed corresponding to this feature
or 2. To send an end-point href as a request header to login.jsp servlet and 
it can be used to build several brunches.

At this point I ran out of ideas. One more thing to mention, is that we 
still need login.jsp to render some handsome interface, because one may try 
to access your secured part directly rather than to ask for Welcome page. It 
became quite handy since browsers track a history and help user to choose a 
url in a combobox below the textbox while he types a domen. That's why we 
must whether redirect user to your sweet login module inside login.jsp, or 
to use login.jsp itself as a destination login url. Last means that we 
should copy/past the body of your Welcome.html and put the directory with 
compiled GWT resources into the root.

Will be greatful, if you give me a solution to maintain url-dependent 
context of login page within one tomcat webapp.

[gwt-contrib] ClientBundle compilation performance

2011-08-15 Thread Paul Robinson


Hi,

I recently introduced an ImageBundle to my code with 1000 images. Everything 
worked ok, but I then converted it to a ClientBundle and found a couple of 
problems:

(1) It seems that ClientBundle holds files open during the compilation where ImageBundle 
does not. I had to dramatically increase the number of open files I was allowed to have 
so that the GWT compile would work. This is on linux, with GWT 2.3. I was getting a 
Too many open files system error.

(2) I had hoped that GWT would work out that I was only using 5 of the images, 
and so wouldn't do anything with all the others. However, GWT appears to open 
all the image files and do something with the data. The compilation could have 
been faster if it had identified which ones were used first, and only did 
something with them. Is this a bug, or an unfortunate but necessary side-effect 
of the way ClientBundle works?

I've now rewritten my code so that the bundle interface only includes the 
images I actually use.

Item (2) is covered by this issue:
http://code.google.com/p/google-web-toolkit/issues/detail?id=6507

but I couldn't find any open issue for (1). Should I open an issue, or is it 
just the way it has to work?

Thanks,
Paul

what's the rationale for this change?  Couldn't it lead to a larger

Now that the files rotate every time a CompilationStateBuilder pass
finishes, there are more files created, but they are smaller.  The
consolidation pass is not needed that often, and I was finding that a 10
file limit mean that one dev mode session was running purge multiple
times.

Just thinking aloud here (since I am wondering about this too with my

What happens if multiple processes are using the cache, if an open

cache file

which is being written to is subsequently read by another process, and

then the

first process adds more to the file, etc., but meanwhile the second

process has

decided to compact things, etc.?  Is this worth worrying about?   Does

it make

sense to instead write new cache info to a temp file, and then only

move it to

it's final file name once it's complete and being closed?  Or should

we have the

concept of cache locking, whereby only one process can ever use a

cache

directory at a time?


The worst thing that could happen: some of the files are corrupt.  In
that case that cache just stops loading the file, deletes it, and moves
on, probably having to re-compile units instead of using them from the
cache.  I don't think the code is going to be able to cache effectively
if multiple processes are sharing the same cache dir, but then again, it
shouldn't break either.

 If you mean the Roll seed-function optimization forward again commit
 [1] (or others before it), yeah, I was hoping that would fix it, but it
 did not.

It surprises me that CFA doesn't take care of this and that it needs
to be done as a fix up. One of the changes I made to CFA was to rescue
indirectly referenced class literals (Object.getClass()) of
instantiable subtypes of Object, if the getClass() method is live. You
may want to look at the method CFA.maybeRescueClassLiteral().
Basically, as CFA  is visiting class literals, it will either rescue
them immediatelly (if the type is instantiable and getClass() is
live), or it will add them to a list of things to be rescued later
when getClass() is invoked.

The thing is, if B is a subtype of A, and B is rescued, then A is also
rescued. So if B's class literal is rescued, A's should as well. Even
if getClass() is never invoked, and all you do is refer to B.class,
the fact is, the class literal holder will look something like this:

class ClassLiteralHolder {
   static final ClassFoo A_classLit = createForClass(..., null);
   static final ClassFoo B_classLit = createForClass(..., A_classLit);
}

So I'd expect that rescuing B_classLit would rescue A_classLit.   I
added Lex who might be able to shed more light on this. I'm not
opposed to doing it in the fixup, the CodeSplitter is not really a
code base I look at very much, but I wonder if we're not missing a
deeper bug, I would hate to have a never ending stream of 'fixups'
that we have to keep extending. :(

 Do you have the repo code?

 Yep:

 https://github.com/stephenh/scalagwt-sample/commit/6cc1b70ae18c31063f71ce27fc110646c65c73c0

 You shouldn't need that whole repo, just the classes in that commit
 (Foo, FragmentA, FragmentB, etc.).

 There is also some discussion on the scalagwt list about the bug [2].
 Note that I misused the L(...) notation in a few places, so read those
 parts liberally.

Oh, no, no plans for an API, just the default that I didn't catch. I
agree, package protected is preferable.
