Re: DockLayoutPanel MVP and events
Hi Thomas
Thanks for your reply, I have started to look into the ActivityManager
and Place patterns, but have not found lots of documentation. Is there
any examples?
Is gwt-p going to be standard for 2.1 or will google release there own
implementation?
Thanks

Hi
Very new to GWT and MVP. Trying to expand the contacts example with a
DockLayoutPanel with a tree navigation in the west section. Using MVP
and ui:bindings.
Got an DockLayoutPanelView and Presenter. Inside is a tree component
to the west and a content component in center. How will I get the
events from the tree component?
The generally adopted way of doing things in GWT is to have custom
events go through the event bus. In this case, you're talking about
navigation, so maybe the concept of place would be better than
just some custom event. I encourage you to look at gwt-platform, gwt-
presenter and other MVP frameworks for GWT, and/or look at the
Activity concept from the upcoming GWT 2.1.
Using actvities, you'd have an ActivityManager managing your center.
The tree would use the PlaceController.goTo to navigate to a new
place. An ActivityMapper (that you passed to the ActivityManager in
the constructor) would map the place to an Activity (a presenter), and
the ActivityManager will manage the current Activity for the display
it manages, i.e.it will stop() the current activity if its ok
(willStop returns true) and then only start the new Activity, which
will call the Display back to show its view.
The tree would probably also listen to PlaceChangeEvent on the event
bus to update the selected item depending on the current place (in
case some other component calls the PlaceController.goTo)
My DockViewPresenter:
public class DockPresenter implements Presenter {
public interface Display {
Widget asWidget();
}
private final ContactsServiceAsync rpcService;
private final HandlerManager eventBus;
private final Display display;
private ContactsPresenter contactsPresenter;
private TreePresenter treePresenter;
public DockPresenter(ContactsServiceAsync rpcService,
HandlerManager eventBus, Display view) {
this.rpcService = rpcService;
this.eventBus = eventBus;
this.display = view;
contactsPresenter = new ContactsPresenter(rpcService,
eventBus,
new ContactsView());
treePresenter = new TreePresenter(rpcService, eventBus, new
MyTree());
}
public void bind() {
contactsPresenter.bind();
treePresenter.bind();
}
public void go(final HasWidgets container) {
bind();
container.clear();
container.add(display.asWidget());
}
}
As you can see I am creating the two presenters for the content and
the tree, but I dont know how to get the events (clicks, selections)
from them. They seem to be swallowed be the dock. I'm guessing I
should register handlers in the bind() method, but how? When
navigating to the tree component without the dock, events works fine.
TreePresenter:
public class TreePresenter implements Presenter {
public interface Display {
HasSelectionHandlersTreeItem getTree();
Widget asWidget();
}
private final ContactsServiceAsync rpcService;
private final HandlerManager eventBus;
private final Display display;
public TreePresenter(ContactsServiceAsync rpcService, HandlerManager
eventBus, Display view) {
this.rpcService = rpcService;
this.eventBus = eventBus;
this.display = view;
}
public void bind() {
display.getTree().addSelectionHandler(new
SelectionHandlerTreeItem() {
public void onSelection(SelectionEventTreeItem event) {
TreeItem item = (TreeItem) event.getSelectedItem();
GWT.log(Node selected +item.getText());
}
});
}

User Management without Google-Accounts
Hi everyone, I want to have a User-Management without forcing the users off my application to have Google-Accounts or something like this. The plan is, that the users should register on my site, and the applcation shall do the management like: - What is the user abc allowed to do and so pn. Users have own data in the datastore. Other users shouldn´t be allowed to access this data. To make this possible I want to store something like a User_ID in every dataset, to make shure, that the data are not shuffeled. I have questions, on how to realize this: - How can I get the userID (stored in datastore in the class Users) on the server, without having the id as parameter?? I don´t want something like this: String myService(String userID, Object data), remember, that I want to have my own dataobjects for the user management - Is it possible to realize this via cookies oder httpsessions? - Does the Google Api provides some functionality for an own user- management?

Re: VerticalPanel inside ScrollPanel inside StackPanel - no scrollbars?
Hi,
I've got it working now. The actual hierarchie is: DockLayoutPanel -
StackLayoutPanel - ScrollPanel - VerticalPanel.
However, what is this all about with these multiple classes for one
and the same thing:
DockPanel - DockLayoutPanel
StackPanel - StackLayoutPanel
...
What's the difference, e. g. between StackPanel and StackLayoutPanel,
and when should I use which?

Hi,
I've got it working now. The actual hierarchie is: DockLayoutPanel -
StackLayoutPanel - ScrollPanel - VerticalPanel.
However, what is this all about with these multiple classes for one
and the same thing:
DockPanel - DockLayoutPanel
StackPanel - StackLayoutPanel
...
What's the difference, e. g. between StackPanel and StackLayoutPanel,
and when should I use which?
Thanks

Not sure abt the ScrollPanel but, I have also found out ( the hard way)
VerticalPanel ( table based ) does not work well with layout panels (div
based) .. Try using a DockLayoutPanel - with all widgets added to the
north - instead... may be worth a try.

Hi Prashant,
I have done everything you said, with some losings, but also without
success (scrollbars):
- I changed the StackPanel into a StackLayoutPanel
- then, the CSS padding (10px) has no effect anymore
(the stack is aligned directly at the left edge, without space, but
ok)
- I added overflow:auto to the inner CSS container, which is a
VerticalPanel
- but there is no scrollbar...
Why doesn't ScrollPanel work here?

The way I would go about doing this is as follows, see if this works for
you or gives any hints:
0. Make sure you are in STANDARDS mode.
1. Use StackLayoutPanel and add it to your parent LayoutPanel ( mixing
StackPanel with a DockLayoutPanel gives unpredictable results - so some
one has said I have found out the hard way )
2. Set the width and height to 100%
3. For the container widget ( FlowPanel / HTMLPanel ) you add to the
StackLayoutPanel, put a CSS overflow: auto. This indicates that if
whatever the container contains grows beyond the container then a scroll
bar is shown. If you have a container within a container, and overflow
setting should be on the right container - just above the element whose
overflow you want to control. Firebug usually helps me figure out this.
Review the container hierarchy using Firebug to make sure that there are
no intermediate containers which makes your setting ineffective.
Hope this helps.

Hi,
I want to show the contents of a log file inside a StackPanel. The log
file itself is a class LogPanel based on a VerticalPanel. Because
the log file grows, I added an intermediate ScrollPanel (see code
below).
The problem: The ScrollPanel never shows scrollbars. Instead, it grows
as the LogPanel grows, beyond the size of the containing StackPanel.
I would like the ScrollPanel to occupy all available space within the
StackPanel and to show scrollbars, when the inner LogPanel gets
bigger.
The demo of the StackPanel class in the GWT showcase application
assumes that there is enough room for the contents.
Can you help?
Thanks!

ScrollPanel p = new ScrollPanel ();

Re: $_POST is empty when request made using RequestBuilder
Hello Again,
For a second I thought the I managed to solve the SOP by following and
applying Google's tutorial found in
http://code.google.com/webtoolkit/doc/latest/tutorial/Xsite.html
But I realized that I was doing a GET request and not a POST
request :/
So I guess I am back to square 1.
I read somewhere on the net that JNSI works only for GET request... Is
this correct?
Is there a way to make a POST request to a PHP page (port 80) without
violating the SOP? a link to an example or manual would be really
great.
Thanks again for the help and tips.

Thanks Rob,
The problem was because I wasn't encoding the URL, Now when I think
about it, it is kind of strange because the logs show that a request
was sent but the only problem was with the $_POST, You would expect
not being able to send the request if you don't encode the url and not
send a request with no parameters.
What was interesting too, the fact that getStatusCode() returned 0. I
checked the group and it seems that it has something to do with SOP
(correct me please if I am wrong). Would having the GWT application in
the same folder as the PHP project solve this issue?
Please, are there any other work arounds to the SOP issue?
Thanks again

Apologies if this is a double-post, the thread didn't seem to update

I don't see anything in particular that is wrong with your code, but
the following works for me if you want to give it a try:
public void postPHPRequest(String url, String postData){
url = URL.encode(url);
RequestBuilder builder = new
RequestBuilder(RequestBuilder.POST,
url);
try {
builder.setHeader(Content-Type, application/x-www-form-
urlencoded);
@SuppressWarnings(unused)
Requestreq = builder.sendRequest(postData, new
RequestCallback() {
public void onError(Requestrequest, Throwable exception) {
fireErrorEvent(Failed to send therequest: +
exception.getMessage());
}
public void onResponseReceived(Requestrequest, Response
response) {
String output = response.getText();
}
});
} catch (RequestException e) {
fireErrorEvent(Failed to send therequest: +
e.getMessage());
}
}
You can look at 'output' which should display any echos you have in
your PHP. Hopefully this will help you debug out what is happening.
If this doesn't work check that you are not violating the SOP (same
origin policy). There are other threads on this forum with more info
on this.
Good luck,

Re: Starting with GWT
well the way i did it and i am sure that this is not the optimal way. Since they dont want to use maven in here i had to create the package *.share.* on svn and share it by the gwt module and any other module/project that needs to use those classes. so when i ran eclipse and import it, it looks like a linked package. regards, Rudolf Michael On Wed, Jul 21, 2010 at 3:28 PM, Vinicius Carvalho viniciusccarva...@gmail.com wrote: Hi there!

Dynamica menu integration with GWT
Hi,
I am working with the GWT SDK 2.0.4, and SDK App engine 1.3.1.
Facing the problem to integrate the dynamic menu integration with the
GWT.
In my jsp file the menu is display based on the login credentials. So
for each user menu is differ. I got GWT Menu to my jsp page but 1) It
display same menu for all user.2) the date related to the user after
login is not shown by clicking the menuitem. It’s because of the
Object related to the login credentials is not integrated with GWT to
Jsp page.
At the GWT project my code is as bellow.
Command cmdTest = new Command() { // at the time of clicking menuitem
public void execute() {
PropertiesManager.getInstance(DEBUG).isActive(MenuItem);
//Window.open(WebApp/request/select_type.jsp,_self,);
}
};
Window.open is working and give me the requested page but the login
related parameters is not fetched with it.
I want to check it at the time on selecting menuitem
PropertiesManager.getInstance(USER).isActive(MenuItem);
PropertiesManager class is on my jsp application. Now after including
jar for the PropertiesManager at the time of gwt compile Project it
gives me error like.

Still the same message is displayed.
I want My application object to the gwt project.

Re: DockLayoutPanel inside custom DecoratorPanel
On 20 juil, 14:00, Jean-luc Chasseriau jean...@kernub.net wrote:
Hi all,
I'm getting the same behavior, only the north part of the DockLayoutPanel is
displayed.
Need to set DockLayoutPanel's height in pixel to make it work.
Running gwt 2.1.0 M2, here is the structure:
Menu extends Composite
Menu() {
panel = new FlowPanel();
panel.add( new HTML( menu ) );
initWidget( panel );
}
Application extends Composite
Application() {
indexPanel = new DockLayoutPanel( PX );
indexPanel.addNorth( new HTML(north blah), 50 );
indexPanel.addWest( new HTML(west blah), 50 );
indexPanel.addEast( new HTML(east blah), 50 );
indexPanel.add( new Menu() );
appDecorator = new DecoratorPanel();
appDecorator.setWidget( indexPanel );
appDecorator.setStylePrimaryName( custom_decorator );
initWidget( appDecorator );
}
RootLayoutPanel.get().add( new Application() );
Few tests:
1) this code, not more: the custom_decorator is displayed, without center,
with north overwriting in the borders.
2) adding: appDecorator.setSize( 100%, 100% );
the decorator is properly rendered, and the center is 100%,100%, but,
only north is displayed from the DockLayoutPanel
3) adding: indexPanel.setSize( 100%, 100% ); AND appDecorator.setSize(
100%, 100% ); = same as (2)
4) adding: indexPanel.setHeight( 100%); AND appDecorator.setSize( 100%,
100% ); = same as (2)
5) adding: indexPanel.setSize( 300px, 300px ); AND appDecorator.setSize(
100%, 100% );
finally! DockLayoutPanel is rendered!
Conclusion:
Need to fix the height in PIXEL to get it work properly.

Search for Using a LayoutPanel without RootLayoutPanel, then look
for RequiresResize and ProvidesResize, which says:
The purpose of these two interfaces is to form an unbroken
hierarchy between all widgets that implement RequiresResize and the
RootLayoutPanel, which listens for any changes (such as the browser
window resizing) that could affect the size of widgets in the
hierarchy.
= keywords: unbroken hierarchy
In your case, maybe you could just implement RequiresResize on your
Application composite to delegate to indexPanel.onResize(), and give
both your widgets a size of 100%.

Java Type Mapping or Compiler Extension
hello folks, I wanted to use already existings beans transparently on the client. The issue is, that they have BigInteger members, which cannot be translated to JS. Now, I did not want to write adapters or TOs but rather patch the GWT compiler to know how to translate such classes. In my case I want the BigInteger to become an String on the client, how to accomplish this? BTW: i am only interested in translation concerns, in case there are some unsupported ops on that type, like new BigInteger(5).add(new BigInteger(5)); the compiler should endup with an error. - is there an option to the GWT module descriptor to give a hint for translation of particular types? - or are there extension points in the code of gwt compiler and, maybe, a little documentation on it so I can patch the sources? thanks -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

IncompatibleRemoteServiceException caused by different RPC Protocol Versions (server: 5, client 6)
Hi folks, i just upgraded one of my projects from 2.0.4 to 2.1.0.M2. The whole reason was to use the new Data Presentation Widgets, which indeed are very cool and working. On the other hand I went into problems on my RPC calls. It seems like the protocol for this has changed: from version 5 up to 6. While debugging I got deeper into the GWT code and so found the corresponding lines. As you can see in the stack trace below, the exception text tells me to reload the browser, but this does'nt help. May anyone know why the server (on jetty) is still using version 5? Or is there another way to force the server/client to use a specific version? I would be very glad if anybody can tell.

Spring Security UI Conditional Rendering
I am running GWT2.0.4 and Spring Security 3.03.
I am able to authenticate with Spring Security but have not found a
good way to conditionally render Widgets and Panels based on ROLES
from Spring Security.
For example: In the StockWatcher program, if a user has a ROLE_ADMIN
then I want to allow that person to add a addPanel. But If the user
has a role such as ROLE_GUEST who is not a ROLE_ADMIN, that user
should not see the panel
I would like to do something like:
public void onModuleLoad() {
.
// Assemble Main panel.
mainPanel.add(stocksFlexTable);
if(SpringSecurityRole == ROLE_ADMIN){
mainPanel.add(addPanel);
}
mainPanel.add(lastUpdatedLabel);
..
}
I know UI conditional rendering can be easily accomplished using jsp
and the Spring Security tags (as shown below). But we don't want to
use jsp
sec:authorize access=hasRole('ROLE_ADMIN')
input type=submit value=Add /
/sec:authorize
I have searched gwt forums , google groups and other GWT book forum
and Spring book forums and have not found a good solution.
I've tried the acris security
http://code.google.com/p/acris/wiki/Introduction
but the roles don't seem to come from Spring Security but rather its
own implementation. It uses Spring Security for server side security
not UI conditional rendering. UI conditional rendering ROLES come from
its own filter
sk.seges.acris.security.server.SessionRemoteServiceFilter and user
define Grants interface.
I've also tried gwt-incubator lib
http://code.google.com/p/gwt-incubator-lib/ but that seems to only
cover authentication and no conditional rendering.
I've seen some news feed about calling back to Spring Security but
didn't know how to accomplish the actual calls.
DoCheckUserAuth checkAuth = new DoCheckUserAuth(); boolean b =
checkAuth.askServerAboutUser();
if(b){
RootPanel.get(formPoint).set(new PrivateForm);}
else
{
RootPanel.get(messagePoint).set(new Label(Please, pass
authorization));
Your help is much appreciated

HTML5 DnD mouse events - Drop not fired, but others are
Hey All,
I've been trying to implement support for HTML5 drag 'n' drop events
in GWT 2.0.3. Thus far i've managed to override the default DOMImpl
with a custom class that supports the events:
i've overridden :
public native int eventGetTypeInt(String eventType) to include...
// other events
case drop: return 0x10;
case dragenter: return 0x20;
case dragexit: return 0x40;
case dragover: return 0x80;
and:
protected native void sinkEventsImpl(Element elem, int bits) {
// other sinkers
if (chMask 0x10) elem.ondrop = (bits 0x10) ?
@com.google.gwt.user.client.impl.DOMImplStandard::dispatchEvent :
null;
if (chMask 0x20) elem.ondragenter = (bits 0x20) ?
@com.google.gwt.user.client.impl.DOMImplStandard::dispatchEvent :
null;
if (chMask 0x40) elem.ondragexit = (bits 0x40) ?
@com.google.gwt.user.client.impl.DOMImplStandard::dispatchEvent :
null;
if (chMask 0x80) elem.ondragover = (bits 0x80) ?
@com.google.gwt.user.client.impl.DOMImplStandard::dispatchEvent :
null;
As well as making Events and their associated handlers for these
events. My problem is that in the browser (FF 3.6), dravover,
dragexit, dragenter work (the events are triggered at least), but
**drop** does not.
Has anybody had any luck achieving this, or care to share an existing
implementation? Is there anything you notice immediately that i'm
doing wrong?

[CHROME] DialogBox seems to interfere with scrolling a ScrollPanel when mouse is over a widget...
Hello guys,
This is ONLY RELEVANT TO GOOGLE CHROME.
I've been googling for this for a while now, so excuse me if it is a
known issue, but I could not find the answer.
I have this code inside an entry point class.
Panel createScrollableStuff() {
VerticalPanel vp = new VerticalPanel();
for(int i = 0; i != 100; ++i) {
HorizontalPanel hp = new HorizontalPanel();
hp.add(new Label(Hello));
hp.add(new Button(Click me));
vp.add(hp);
}
ScrollPanel sp = new ScrollPanel(vp);
sp.setHeight(30em);
sp.setWidth(30em);
return sp;
}
public void onModuleLoad() {
RootPanel.get(rootPanel).add(createScrollableStuff());
DialogBox db = new DialogBox(true, true);
db.setGlassEnabled(true);
db.add(createScrollableStuff());
db.center();
}
It creates a list of widgets inside a scrolling list, both in a dialog
box, and directly on the page itself.
Now, if I hover my mouse over a button and scroll, the list will
scroll on the page, but NOT in the dialog box... what's going on?
Thanks

External library on GWT server side.
Hi all,
I faced with following problem. I want to you use cryptix library on
the server side of my app. I creared classfile :

package com.rfo.cabinet.server;
import java.util.Random;
import cryptix.provider.md.MD5;
public class TestHash {
...
public static String encrypt() {..}
}
[/code]
Then I'm using it in RPSImpl:
[code]
public class GreetingServiceImpl extends RemoteServiceServlet
implements
GreetingService {
...
String sid = this.getThreadLocalRequest().getSession().getId();
String encryptedSid = TestHash.encrypt(sid);
Cookie cookie = new Cookie(Sid,encryptedSid);
this.getThreadLocalResponse().addCookie(cookie);
...
}
[/cpde]
Progect is pompiling well but when I call this service, I'm getting
next exception:

Re: $_POST is empty when request made using RequestBuilder
hi!
so if you really need to go for HTTP POST rather than get, then do so,
remove the '?' from post body, these would be required for CGI doing
GET but not in this case.
you dont need to go for JSNI!! SOP cannot be workarounded on the
client solely. You have to write simple gateway service which you call
from the client (via RequestBuilder or XMLHttpRequest) and the data is
posted via socket from the backend to the destination server.
also refer to this howto:

Right before I send therequestI display therequestdata and they

urlencoded);
StringBuffer requestData = new StringBuffer();

requestData.append(URL.encode(key));

Re: $_POST is empty when request made using RequestBuilder
btw:
you can of course abuse HTML resource reference tags allowing SOP
( like SCRIPT, IMG, IFRAME ) but they all do only support HTTP GET. If
your service you gonna talk with requires HTTP POST, there is no other
way
you can also patch your DNS but this is for sure not the way you look
for...

Hello Again,
For a second I thought the I managed to solve the SOP by following and
applying Google's tutorial found
inhttp://code.google.com/webtoolkit/doc/latest/tutorial/Xsite.html
But I realized that I was doing a GET request and not a POST
request :/
So I guess I am back to square 1.
I read somewhere on the net that JNSI works only for GET request... Is
this correct?
Is there a way to make a POST request to a PHP page (port 80) without
violating the SOP? a link to an example or manual would be really
great.
Thanks again for the help and tips.

Thanks Rob,
The problem was because I wasn't encoding the URL, Now when I think
about it, it is kind of strange because the logs show that a request
was sent but the only problem was with the $_POST, You would expect
not being able to send the request if you don't encode the url and not
send a request with no parameters.
What was interesting too, the fact that getStatusCode() returned 0. I
checked the group and it seems that it has something to do with SOP
(correct me please if I am wrong). Would having the GWT application in
the same folder as the PHP project solve this issue?
Please, are there any other work arounds to the SOP issue?
Thanks again

Apologies if this is a double-post, the thread didn't seem to update

I don't see anything in particular that is wrong with your code, but
the following works for me if you want to give it a try:
public void postPHPRequest(String url, String postData){
url = URL.encode(url);
RequestBuilder builder = new
RequestBuilder(RequestBuilder.POST,
url);
try {
builder.setHeader(Content-Type, application/x-www-form-
urlencoded);
@SuppressWarnings(unused)
Requestreq = builder.sendRequest(postData, new
RequestCallback() {
public void onError(Requestrequest, Throwable exception) {
fireErrorEvent(Failed to send therequest: +
exception.getMessage());
}
public void onResponseReceived(Requestrequest, Response
response) {
String output = response.getText();
}
});
} catch (RequestException e) {
fireErrorEvent(Failed to send therequest: +
e.getMessage());
}
}
You can look at 'output' which should display any echos you have in
your PHP. Hopefully this will help you debug out what is happening.
If this doesn't work check that you are not violating the SOP (same
origin policy). There are other threads on this forum with more info
on this.

Re: AJAX of type GET ( and not POST)?
Hi, what do you expect from using GET instead of POST? Basically POST could definitely transfer many bytes, GET may have a limit.

The server application has no way of magically accessing client files. Depending on how the web server is configured, it might not be allowed to access files on the server itself. After all, the operators of a web server might be hosting web applications from many different sources. Those operators don't want these applications to interfere with each other or the operations of the server itself. How is your server configured? I assume the file name D:/q.xls is a placeholder for something else; otherwise, you could include it in your WAR file.

Re: Spring Security UI Conditional Rendering
Conditional rendering (i.e. hiding certain UI) would have to be done
manual or using something like Acris or Errai Workspace:
http://www.jboss.org/errai/Components/Workspaces.html. At the end of
the day, unless you're adding additional generator conditions to strip
non-admin parts based on authority, there's not much you can do to
prevent the user from opening firebug or web inspector and looking at
all your hidden elements. Spring Security (AFAIK) strips out the
conditionally rendered pieces because it sends back the entire page
(web 1.0 style). So your options are as follows:
1) pull out the permissions from Spring Security, store it client side
and do conditional rendering yourself by hiding ui pieces.
2) use a framework like Acris or Errai workspace.
3) build out some custom UIBinder parsers and some generators to
physically remove the conditionally rendered parts, then modify the
selector script to pull the appropriate generated files based on
authentication.
The last option is going to be a huge amount of work and really
doesn't give you additional benefit. The user can be as malicious as
they want on the client side (unhide admin functionality) as long as
you never trust anything that comes from the client side.

I am running GWT2.0.4 and Spring Security 3.03.
I am able to authenticate with Spring Security but have not found a
good way to conditionally render Widgets and Panels based on ROLES
from Spring Security.
For example: In the StockWatcher program, if a user has a ROLE_ADMIN
then I want to allow that person to add a addPanel. But If the user
has a role such as ROLE_GUEST who is not a ROLE_ADMIN, that user
should not see the panel
I would like to do something like:
public void onModuleLoad() {
.
// Assemble Main panel.
mainPanel.add(stocksFlexTable);
if(SpringSecurityRole == ROLE_ADMIN){
mainPanel.add(addPanel);
}
mainPanel.add(lastUpdatedLabel);
..
}
I know UI conditional rendering can be easily accomplished using jsp
and the Spring Security tags (as shown below). But we don't want to
use jsp
sec:authorize access=hasRole('ROLE_ADMIN')
input type=submit value=Add /
/sec:authorize
I have searched gwt forums , google groups and other GWT book forum
and Spring book forums and have not found a good solution.
I've tried the acris security
http://code.google.com/p/acris/wiki/Introduction
but the roles don't seem to come from Spring Security but rather its
own implementation. It uses Spring Security for server side security
not UI conditional rendering. UI conditional rendering ROLES come from
its own filter
sk.seges.acris.security.server.SessionRemoteServiceFilter and user
define Grants interface.
I've also tried gwt-incubator lib
http://code.google.com/p/gwt-incubator-lib/ but that seems to only
cover authentication and no conditional rendering.
I've seen some news feed about calling back to Spring Security but
didn't know how to accomplish the actual calls.

Re: Sync AJAX ( instead of async)
indeed it could be a valid use case; but not without a constraint, just imagine I wanna close my browser and your sync onunload() request would take 5 secs to be processed by server - what happens then? its evil! imho, if you want to process the response afterwards, like printing it out to the user, anyway you should convince him about it - so the user is not surprised that his browser gonna hang for few seconds. and here you can alert() him about that, or even acquire a confirm()ation - in both cases you can use it as an sync point on the browser while processing async request On 21 Jul., 17:10, Nathan Wells nwwe...@gmail.com wrote: There is only one case I know of where synchronous should be used: when you want to do a server call and get a response when the user is leaving the page.

Re: Sync AJAX ( instead of async)
I understand that asynchronous is the way to go and sometimes we change UI design just to support async. But atleast in our project, there are functional requirements where sync is the only solution. (BTW: sync is not as bad. I understand that javascript in browser is single threaded but it's used by a single user to do a single task. And if sync response is required to meet functional need than we got to do sync. It does not effect scalability of whole app ) Anyway any body used any hack to support sync.

Re: Sync AJAX ( instead of async)
I see, i think google just did not want to make a tool which can be abused resulting in frustrated users :) but anyway, you can endeed get it simpler than just hacking JSNI from scratch - extend the XMLHttpRequest class and add a new method open() which flags the underlying connection as async (by simply provide 'false' instead of 'true').

Re: Upload Maximum Size file giving Memory Out of rage error
stop doing that, its not your intention to load the entire filestream into the memory?! :-) you'd be better off with streaming, so on doPost() in your servlet you could acquire a stream from the request and forward it to your outputstream on the file system, so only the internal buffer is used.

For better debug you could also assign a border and background color
to the Grid. If none of these colors will be visible you can be sure
that there are no spaces or anything left.

Me personally, I would not spend much time in fixing it for IE6 if it
can not be fixed by slightly adjusting the UI setup in such a way that
it still works correctly on modern browsers.

Re: Possible to access GWT-RPC serializer?
Thanks guys. Yau: that's an interesting technique, but not quite what I need (which is to marshal/unmarshal on the client side for local storage). Olivier, I can't quite make out how your stuff would work, but I see it's basically annotation based and generates the marshal/ unmarshal code - which is what I actually ended up doing myself. For those interested, I've implemented an annotation of my own (@JsonSerializable). All you need to do is add this to the classes (or enum types) that need serialization, and the processor looks at the public fields and generates the marshal/unmarshal code. Works for the basic Java types as well things like enum and ArrayList and handles nested classes (which I use a lot). Pretty neat and extremely handy, if you're considering local storage. Except, implementing annotations is a pain if it's the first time (it was for me and took me a couple of days to implement/test), so once my project eases up, I'll try to upload the library for others who might want to use local storage this way. I can tell you the results are excellent. If you want to see this in operation and decide if it's worth the effort, check out my app at http://herdcall.com - it's beta right now, but it's open at this time. You don't need to set up an account, log in with your Facebook or Gmail login (LinkedIn, Twitter, and Yahoo! not operational yet). Everything is cached in local storage, including your friend (herd) list, for which you'll see dramatic improvement in load time.

This part starts to work with (many) limitations. The second part is to create some Java proxy to use the same mechanisms on server. I'm owrking on. Maybe this code can help you.

I don't think overlays help because the JavaScript side never sees the objects (just the string) and the JSON-POJO process shouldn't depend on the specific class.

Re: how to control the pixel sizes of a Grid?
Hi Andreas,
the most ugly thing concerns the chess board, which I set up with
SimplePanels based on your idea:
There are gaps between the columns.
Look at this:

I find that most web apps still work good with old browsers, and I am
not sure if my app should look better with IE6...

Hey Magnus,

Besides, what exactly is looking ugly?
Me personally, I would not spend much time in fixing it for IE6 if it
can not be fixed by slightly adjusting the UI setup in such a way that
it still works correctly on modern browsers.

spaces, correct me on this one?
For better debug you could also assign a border and background color
to the Grid. If none of these colors will be visible you can be sure
that there are no spaces or anything left.
For the inner cells I can not say if there are any spaces.
Also I assume your style pnl-r adds the red border to the Grid? If
there were any spaces left caused by the border width you would see a
red Grid.
I think you got what you wanted...
BTW: I think you do not need to set the cell dimensions manually; Grid
will automatically adjust cell dimensions so that the cell widgets
fit, in other words a columns width for example will be adjusted so
that the cell widget with the biggest width is completely visible;
same goes for rows and heights and so on
BTW2: the two for-blocks in init() can be realized in one single for-
block since they iterate over exactly the same interval (0-9)

Re: file upload set filter
Well, first of all if you notice the link I posted earlier, none of the browsers implement the spec.

Re: Sync AJAX ( instead of async)
Could you get the same effect by preventing user input during your server request, either by finding all of the controls/links and disabling them or overlaying something that receives and swallows all events?

Re: XSL Transformation, AccessControlException, NoClassDefFoundError and SyntheticRepository
From what I can tell it is failing while compiling the stylesheet. I would suggest taking app engine out of the loop altogether first and just so it in a static main to make sure it is compiling. If it works as a static main than it is probably the file IO. To test this I recommend to try just reading the file to the log to make sure that you actually have a hold of the file. I have found that the most reliable way to read in a file is not to use the File constructor, but assuming the name of your class is XsltService: XsltService.class.getResourceAsStream(test.xsl); // Assuming test.xsl is in the same folder as the class file, set to /test.xsl if it is in the root.

Focus problems moving from RootPanel to RootLayoutPanel
I'm testing moving my application from a RootPanel to RootLayoutPanel. Given my layout, it's not a 1-to-1 swap, and the end result is some focusing problems with my logon from. My HTML page contains an iframe for GWT history, an iframe that serves as target for downloading files (so I don't have to open a browser window), a form for logging on, and a div for my application that RootPanel.get(String) retrieves. The logon form's action is attached via JSNI. The HTML page carries and onload() script that focuses the cursor in the username field. After logon, the form is hidden and the application div shows. On logout, I hide and clear the main panel and show the logon form. This works fine in all browsers. However RootLayoutPanel has no get(String) method. So I call get().add(new ScrollPanel(myAppPanel)), bypassing the old div. This *seems* to work well, but if the user clicks *anywhere* on the page, the form loses focus. The focus cannot be regained unless the user tabs through the browser window waiting for the username to highlight. Looking in Firebug, I think the problem is a div of GWT's making: div style=position: absolute; z-index: -32767; left: -20cm; top: -20cm; width: 10cm; height: 10cm;nbsp;/div Is that's what's doing it? What is this div for? How can I get around this focus problem, or do I need to stick with RootPanel? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT 2.1 with roo: custom changes to .ui.xml files overwritten (major issue)
Hi, Before filling a bug with this, I'd like to understand the intended behavior of roo 1.1 final version. A common use case, which I just tried, is developing a small app, and customizing the generated .ui.xml files. For example, for Employee entity, I have changed EmployeeDetailsView.ui.xml. Then I've added another field to the entity, resulting in EmployeeDetailsView.ui.xml being regenerated and my changes lost on mvn gwt:compile. Changes to ScaffoldShell.ui.xml were preserved. I'd rather have roo/maven detect the file was changed and ask me to overwrite or not. I'd also expect it to preseve changes to other files, e.g. I might add an auto-completion widget and handle it myself in the edit view. Do these use cases make sense? How should them be handled with roo +gwt ? PS: also posted here http://forum.springsource.org/showthread.php?p=310300#post310300 Thanks -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: XSL Transformation, AccessControlException, NoClassDefFoundError and SyntheticRepository
as already states by cause Caused by: java.security.AccessControlException: access denied you are not allowed to access the filesystem neither for read nor for write - I remember there was a workaround for this issue, like putting the resource into classpath or such, then you can get the stream via getResourceAsStream(foo.xslt) from the classloader. this should be stated in appengine faq good luck, On 21 Jul., 20:23, lineman78 linema...@gmail.com wrote: From what I can tell it is failing while compiling the stylesheet.

To test this I recommend to try just reading the file to the log to make sure that you actually have a hold of the file. I have found that the most reliable way to read in a file is not to use the File constructor, but assuming the name of your class is XsltService: XsltService.class.getResourceAsStream(test.xsl); // Assuming test.xsl is in the same folder as the class file, set to /test.xsl if it is in the root.

Re: External library on GWT server side.
hi, as the cause indicates java.lang.NoClassDefFoundError: cryptix/
provider/md/MD5 means that the class could not be found, means is
not in the classpath. I guess you uploaded your application on googles
appengine?
however, make sure, that the .jar file of your crypter library resides
in WEB-INF/lib folder!

Hi,
Actually our application deals with monitoring the websites.
when we make the request through our application we start storing all
the resources required by the site (like jpeg,png,hlp,html,js etc)
sent the by the webiste in the DB. and then subsequently store all the
responses until the request is completed. just like recording all the
steps required to access the url that can be played back..
Note : Requesting site comprises of GWT,JSON,Ajax,JSNI scripts.
And our Application environment : Eclipse 3.2.2 jdk 1.4.2 ( we may
not support higher version of JDK)
Now the issue is
1. Normal browser opens the site without any problem
2. through our application the same browser is experiencing Technical
Error.
Our investigation through firebug(Mozilla) reveals that when opening
to the normal browser its giving error while loading the a.
a = Type Error: null has no properties { message=null has no
properties, more...}
after that its is resolving a object is a=haf([object Object]
XX.
But when the browser opened through our application its giving
a =TypeError: null has no properties { message=null has no
properties, more...}
after that it is continuously giving exception like.
a=com.google.gwt.user.client.rpc.Invocation Exception
at the end its throwing Technical exception.

Re: XSL Transformation, AccessControlException, NoClassDefFoundError and SyntheticRepository
This seems very similar to issue 4267. The issue is the GWT is setting a system property, overriding the default transformer factory. This causes the appengine server to get the wrong transformer factory. The exception you are getting is not exactly the same as the bug, but the circumstances are very similary. A workaround is, in your servlet, set the system property yourself to the java default. This should fix the server (although it might cause an issue in the GWT client, if you are using XML). Note that this is only an issue in the development server and not in production. Here is the issue: http://code.google.com/p/google-web-toolkit/issues/detail?id=4267 Please go and check this issue so it get's some attention. Here is the line of code to set the property on the server to work around the GWT bug: // // When using GWT with appengine, we must override the // default TransformerFactory because GWT writes an invalid // default that causes an exception when trying to // render a XML Representation.

Re: Needing help, building a Login
hi, you dont need to care for session ids, unless cookies are disabled, since almost every servlet container (tomcat, appengine,etc) creates a new sessionid for every request it does not recognize and this sessionid is sent back with a cookie. from now on, the browser automatically sends a cookie for EVERY request from the page, including RPC calls - so you just save whatever you want on the serverside via request.getSession().setAttribute(USER,user); it will work out if you want to support users with cookies disabled, this would be a bit tricky and needs some conventions On 21 Jul., 16:41, AlexG alexander.gauss.ax...@googlemail.com wrote: Hi @ all, I want to build a Suer-Management System, where Users can Login und persist personal Data.

What I want, is to save a session id on the client, recieved from the server when logging in. Then for future RPC´s I want to automatically send the session-Id whit it, to identify the users. In the tutorial they say, send the session-Id within the payload of future RPC. My question is, how can I do this? How can I modify the payload, to send the session-Id with the RPC? The following question will be, how can I read this Id from the payload on the server? It would be nice if someone can help me.

Re: Opening a file
hi actually, this is a question to googles appengine forum, appengine implies many restriction, such as those, you cannot access the filesystem, put the excel file into classpath and access the stream via getResourceAsStream(foo.xls) from your classloader br, On 21 Jul., 16:26, Eric erjab...@gmail.com wrote: The server application has no way of magically accessing client files. Depending on how the web server is configured, it might not be allowed to access files on the server itself. After all, the operators of a web server might be hosting web applications from many different sources. Those operators don't want these applications to interfere with each other or the operations of the server itself. How is your server configured? I assume the file name D:/q.xls is a placeholder for something else; otherwise, you could include it in your WAR file. If the real file comes from your client, use an upload control and an upload handler. Eric -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Dev plugin for firefox 3.7
I'm having the same problem ... just built development plugin from trunk but FF 4.0 still displays its Plugin required... stuff. Working on Ubuntu with actually only newest versions of browsers (Chrome dev channel and FF 3.6 4.0). At least for FF 3.6 a working development plugin exists. Hope this will change soon... Does anyone have a working setup for this combination?: - Ubuntu - GWT Development Mode - Browser supporting Websockets What about other OS? I had it running with FF 4.0 and development plugin build from trunk like two weeks ago but apparently it does not work anymore.
