GWT CellTable.Resources causes Deferred binding exception
Hello
GWT 2.4
I am getting the following exception trying to instantiate a CellTable
Caused by: java.lang.RuntimeException: Deferred binding failed for
'com.google.gwt.user.cellview.client.CellTable$Resources' (did you
forget to inherit a required module?)
The offending code is:
@UiField(provided=true)
CellTable derivedCellTable = new CellTable(20); <--
Fails during Instantiation
I get the same Exception instantiating a CellTable NOT in the UiField.
Code will work maybe 10% of the time. Not always. celltable seems
very tempermental.
Does anyone have any thoughts?
- thanks

Re: Can't get correct DOMImpl when chromeframe installed but turned off
I find a workround, if I comment out the chromeframe check it would be
ok.
I'm not sure why it's needed, it only checks the chromeframe plugin is
installed but doesn't check if it's activated or not.
in my IE8 + chromeframe 13, if it's activated, the userAgent would
already contain "webkit".

Can't get correct DOMImpl when chromeframe installed but turned off

Re: GWT 2.1 DateTimeFormat & locale changes?
I think I have solved my date/time issues by forcing a locale, but I would welcome suggestions for a better solution. In my module XML, I added the following line to include some internationalization code: I added the following line to my module XML for my locale: Including the locale extend-property increases the GWT compile time, since the compile does each browser/locale combination. This was the most undesireable piece of my solution since it basically doubled my GWT compile times. I tried to set the default locale using another bit of XML found at http://code.google.com/intl/es-AR/webtoolkit/doc/latest/DevGuideI18nLocale.html#LocaleDefault, but I could not even get the GWT compile to work when including that XML. The last required piece was adding the following line in my HTML file: This gives it a default locale, but I believe that it can be overridden with request parameters. I did test this on a couple projects, and it worked for both. However, I did not test with different locales. It seems that a new GWT 2.1 project has the same issues, so this is not just a GWT 2.0 conversion problem -- I tested by adding a DateBox to a new GWT default project.

GWT 2.1 DateTimeFormat & locale changes?
Hello, I recently made some tool updates to Helios & GWT 2.1, and everything looks pretty good. However, I am seeing some changed behavior regarding the date/time formatting and locales. Previously, my "out- of-the-box" compile gave me "en-US" formatting (12 hr times, week starting on Sun, and mm/dd/yy). Now, I am seeing 24 hr clock, weeks starting on Monday, and -mm-dd formatting. I changed my DateTimeFormat calls to the deprecated 'getShortDateFormat' to 'getFormat(PredefinedFormat.DATE_SHORT)' without any luck (and similar changes for other date/time functions). I did include the "" based on guidance found at http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsFormatting.html. However, this did not seem to help. Suggestions?

Re: How to get the next "day of week" date?
I have not tested the edge conditions around daylight savings times, but I found this useful: import com.google.gwt.user.datepicker.client.CalendarUtil; Date now = new Date(); int nDays = 1; CalendarUtil.addDaysToDate(now, nDays); The number of days can be negative if you need to go back. There are a few other useful functions in there too. Good luck, Rick -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Handling session timeout
There are many ways to handle it. You should decide what is important to your users and for your environment, and how you define a session expiration. In one GWT application, I use the Google UserService to get the current user on the server side. I make sure the user is logged in at the start, and I make sure that I handle expired sessions throughout the application when the user makes a new request to the server. It does nothing to detect session expiration on the client side, but the valid session duration is defined in days. Here's a link to a good starting point that uses a timer to detect and process inactivity on the client: http://gwt-ext.com/forum/viewtopic.php?t=1682 The code in the above link uses GWT-Ext widgets, but can be easily adapted to use standard GWT widgets. Keep in mind that there are many different variations of how you define inactivity... Some servers declare your session dead if you have not sent a message in some amount of time -- you could periodically send a "ping" message to insure your session does not go stale. BUT, that may cause you to exceed your request quotas on the Google servers. Then, consider the user experience. If your application is working correctly, your user may not know when messages are going between client/server. So, you may need to track something else to determine when the session is inactive. Lastly, consider how the users see the session expiration. In one GWT application, I did something similar to what is shown in the GWT-Ext link. Some folks using the app did not like the idea that they had been logged out without seeing where in the application they were. So, I changed my app to tell them they had been logged out (with a dialog box), and upon acknowledging the message they were sent to another page. I do not know your particular design constraints, but I think I have given you the highlights of things to consider.

Re: Handling session timeout
There are many ways to handle it, but you need to consider how to present it to your users and other constraints specific to your environment. In one GWT app, I did nothing to detect client-side inactivity. I used the Google UserService to detect session expiration on the server side whenever there was a message from the client (and I wrote the code to handle those case). The Google UserService lets you see the policy on how long the sessions stay active, but it is often measured in days. So, it did not seem worthwhile to write code to handle the session expiration. Here's a link to a client-side that attempts to detect session expiration: http://gwt-ext.com/forum/viewtopic.php?t=1682 The code uses GWT-Ext widgets, but can be easily adapted to use standard GWT widgets. Some servers consider a client's session inactive if they have not received a message from the client in some period of time (as shown in the example). The example code can be adapted to periodically send a "ping" message to the server instead of just detecting messaging inactivity. You probably do NOT want clients sending "pings" to you application if it is deployed on Google's servers, since the pings will probably count against you request quota. Another thing to consider is that if your application is working correctly, the user may not even be aware when messages are exchanged between client/server. For this reason, you may want to introduce some other means of tracking inactivity. Lastly, you need to determine how you want session expiration presented to your user. My users did not care for the way the GWT-Ext example informed the user (particularly if they missed the refresh prompt). My solution was to keep the user at the same screen and present a dialog box informing them when their session timed out. Upon acknowledging the message, they were sent to another place. I tried to hit the highlights of things for you to consider regarding session expiration, but I think you need to tailor your solution for your environment.

GWT "Unable to contact the server."
I'm running GWT 2.0, app engine 1.3, with Eclipse Galileo Build id: 20090920-1017, Java java-6-openjdk, on Ubuntu 9.10. Starting recently -- within the past few weeks -- I started getting the error, "Unable to contact the server" when I restart my GWT/app engine application and reload the application's web page from Firefox. If I restart Eclipse, it usually eliminates the problem temporarily, but not always. This problem is sucking a significant amount of my time -- I've even had to reboot on occasion to make it go away. The exception stack trace is below. I'd really appreciate any ideas.

Re: How to use UIBinder to create customized tags
Thanks Thomas
Widgets are now adding by implementing HasWidgets interface.
But I need to do a little more. As there are tags in DockLayoutPanel
-- , , in the same way, I want to create my own
customized tags like , etc so that I can arrange my
layout accordingly. Can it be possible. If it is, kindly let me know
as it will be a great help for me to design my UI with more
flexibility,

Re: Panel is giving its offset width before super.onAttach() is called

Sorry to say expected behaviour entered wrong. It should be:

Before super.onAttach called Offset width:500
After super.onAttach called Offset width:500
Expected output
Before vp attached to RootPanel Offset width:0

Panel is giving its offset width before super.onAttach() is called
Hi all
I am making an application using GWT 1.7. But I am surprised by the
behaviour I got. I took a vertical panel and add a button on this. I
set width of button to 500px. Now What I was expected that in onAttach
() of Vertical panel, before calling super.onAttach(), the offsetWidth
of vertical panel should be zero. But it is giving me 500px.
VerticalPanel vp = new VerticalPanel() {
@Override
protected void onAttach() {
GWT.log("Before super.onAttach called Offset width: " +
getOffsetWidth(), null);
super.onAttach();
GWT.log(After super.onAttach called Offset width: " +
getOffsetWidth
(), null);
}
};
Button b = new Button("Hello");
b.setWidth("500px");
vp.add(b);
GWT.log("Before vp attached to RootPanel Offset width: " +
vp.getOffsetWidth(), null);
RootPanel.get().add(vp);
Actual output
Before vp attached to RootPanel Offset width:0
Before super.onAttach called Offset width:500
After super.onAttach called Offset width:500
Expected output
Before vp attached to RootPanel Offset width:0
Before super.onAttach called Offset width:500
After super.onAttach called Offset width:500
Thanks and regards

Problem while clearing a panel
Hi all
I have added some child widgets in a vertical panel before vertical
panel got attach. Now a child widget has thrown some exception in its
onAttach method. Now want to clear this panel, but no way I am getting
'java.lang.IllegalStateException: Should only call onDetach when the
widget is attached to the browser's document'
Sample code to produce the bug:
VerticalPanel v = new VerticalPanel();
Button b = new Button() {
protected void onAttach() {
if (true) {
throw new ResourceException("Exception in
onAttach");
}
super.onAttach();
}
};
v.add(b);
try {
RootPanel.get().add(v);
} catch (Exception e) {
} finally {
try{
v.clear();
}catch(Exception e){
}finally{
Window.alert("Finally" + v.getWidgetCount());
}
}
Thanks and Regards

Problem while loading stylesheet dynamically
Hi All
I am building an application using GWT 1.6. In my application I need
to load external stylesheet at runtime. But its not working. I am able
to load stylesheet in an independent html file. But when I am using
same with GWT, its not reflecting. Below is a sample code to produce
this case. Any help/suggestion will be highly appriciated.
StyleSheetEntryPoint.java
package com.example.foo.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.HTML;
import com.google.gwt.user.client.ui.RootPanel;
public class StyleSheetEntryPoint implements EntryPoint {
public void onModuleLoad() {
loadStyleSheet();
HTML html = new HTML("Hello");
html.setStyleName("sendButton");
RootPanel.get().add(html);
}
public static native void loadStyleSheet()/*-{
var fileref=document.createElement("link");
fileref.setAttribute("rel", "stylesheet");
fileref.setAttribute("type", "text/css");
fileref.setAttribute("href", "Component.css");
document.getElementsByTagName("head")[0].appendChild(fileref);
}-*/;
}
Component.css
.sendButton {font-weight:bold;font-size: 16pt;}
Following HTML is giving me expected behaviour.
function loadCSS(){
var fileref=document.createElement("link");
fileref.setAttribute("rel", "stylesheet");
fileref.setAttribute("type", "text/css");
fileref.setAttribute("href", "Component.css");
document.getElementsByTagName("head")[0].appendChild(fileref);

Problem using Google Visualization with DockPanel
Hi all
I am using GWT 1.6 and Google Visualizations to show graph in my
application. I have to show multiple graphs to user. For this, I am
adding my visualization graphs in a DockPanel with direction. Now If I
add graphs before attaching DockPanel, all graphs are rendered
properly in all browsers. But I have to do my work after attaching
DockPanel. In this case, in Mozilla and Chrome, only last graph added
in dockpanel get rendered where as in IE, all graphs are rendered
properly. Kindly note that this problem occurs only when I am adding
Graphs in DockPanel. In other containers like VerticalPanel &
HorizontalPanel, I can add Graphs after attaching container, it works
well.
Below is a sample code to produce this case. Any help/suggestion will
be highly appriciated.
Code:
package com.example.simpleviz.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.DockPanel;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.Widget;
import com.google.gwt.visualization.client.DataTable;
import com.google.gwt.visualization.client.VisualizationUtils;
import
com.google.gwt.visualization.client.AbstractDataTable.ColumnType;
import com.google.gwt.visualization.client.visualizations.BarChart;
import com.google.gwt.visualization.client.visualizations.PieChart;
import
com.google.gwt.visualization.client.visualizations.PieChart.Options;
public class MyClass implements EntryPoint {
public void onModuleLoad() {
VisualizationUtils.loadVisualizationApi(new Runnable() {
public void run() {
Widget bar = createBarChart();
Widget pie = createPieChart();
DockPanel d = new DockPanel();
RootPanel.get().add(d);
d.add(bar, DockPanel.NORTH);
d.add(pie, DockPanel.NORTH);
}
}, new String[] { BarChart.PACKAGE, PieChart.PACKAGE});
}
private Widget createPieChart() {
DataTable data = DataTable.create();
data.addColumn(ColumnType.STRING, "Task");
data.addColumn(ColumnType.NUMBER, "Hours per Day");
data.addRows(1);
data.setValue(0, 0, "Work");
data.setValue(0, 1, 10);
Options options = Options.create();
options.setWidth(200);
options.setHeight(100);
options.set3D(true);
options.setTitle("My Daily Activities");
PieChart pie = new PieChart(data, options);
return pie;
}
public Widget createBarChart() {
DataTable data = DataTable.create();
data.addColumn(ColumnType.STRING, "Year");
data.addColumn(ColumnType.NUMBER, "Sales");
data.addColumn(ColumnType.NUMBER, "Expenses");
data.addRows(4);
data.setValue(0, 0, "2004");
data.setValue(0, 1, 1000);
data.setValue(0, 2, 400);
BarChart.Options options = BarChart.Options.create();
options.setWidth(200);
options.setHeight(100);
options.set3D(true);
options.setTitle("My Daily Activities");
BarChart barchart = new BarChart(data, options);
return barchart;
}
}
Thanks and regards

Re: RPC call efficiency
Hi all Thanks for your replies. Let me specify one more thing which might help us in figuring out my problem. My application server is in US and and I am accessing it from India. During a discussion with one of colleague, this point came that there should be a minimum time that a request will take for coming back from US based server. But we don't know what this minimum time should be in best & average conditions. Further, when I tried to ping google.com with command "ping google.com -t", I got following result: Pinging google.com [74.125.45.100] with 32 bytes of data: Reply from 74.125.45.100: bytes=32 time=370ms TTL=241 Reply from 74.125.45.100: bytes=32 time=354ms TTL=241 Reply from 74.125.45.100: bytes=32 time=340ms TTL=241 Reply from 74.125.45.100: bytes=32 time=370ms TTL=241 Reply from 74.125.45.100: bytes=32 time=341ms TTL=241 Ping statistics for 74.125.45.100: Packets: Sent = 5, Received = 5, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 340ms, Maximum = 370ms, Average = 355ms It is showing 355ms average time but total time elapsed in starting pinging and pausing for these 5 packets was 5 seconds. Then avg ping time should be around 1 sec. Now again I got more confused why it is showing 355ms. When I tried to ping my server, it's avg time was 375 ms. I also tested by returning a String value but same problem with it also. Regarding testing AJAX call using an example in core JS, I am sorry but I don't know how to write this as I have worked only in GWT for AJAX applications. It will be very helpful if one can provide such example or help in writing this. Please let me know if further I can provide some information which can help in figuring out my problem.

Hi Thanks for reply.When I deploy application on local machine, RPC call get returned in 20 ms but when this application get deployed on Remote server, RPC call is taking 1000 ms. I am just returning a hard code long value from server.

RPC call efficiency
Hi I am using Java as server so I used RPC calls. The thing worrying me is the efficiency of RPC call. I just write a simple method getValue() on server which returns a long value. When I called it from client, it is taking 1 second to go to server and then come back. This 1 second time is pinching the performance of my application and I can't afford it. Can any one suggest what improvement should be done so that this time get reduced. Any suggestion in this regard will be highly appreciated .

Re: how to redirect to another EntryPoint class
Hi
For redirection you can use following method:
public static native void reDirectPage(String html)/*-{
var text = $wnd.location.href;
var index = text.lastIndexOf("/");
var subString = text.substring(0,index+1);
var targetString = subString+html;
$wnd.location.href = targetString;
}-*/;

Google chrome issue with GWT in History Management
Hello All
I am a facing a issue regarding History Management. I am performing
two actions on two button click. One button adds node in history using
History.newItem. and Second button redirects it to the same HTML page
again. Following code is used to redirect it:
public static native void reDirectPage(String html)/*-{
var text = $wnd.location.href;
var index = text.lastIndexOf("/");
var subString = text.substring(0,index+1);
var targetString = subString+html;
$wnd.location.href = targetString;
}-*/;
But after adding nodes in history , redirection is not happening in
Chrome whereas it is working fine in Mozilla and IE. In chrome it just
replace the URL and does not load entrypoint again.
Is it a bug of Google Chrome or I am using wrong way of redirecting.
Any comments in this regard will be highly appreciated.
Thanks and regards
Rick Smith

Re: Can Google Adsense be used with GWT
Hi Arthur Thanks for feedback. I placed the script provided by Google into HTML file and it was working nice. But I want little more. I want to use it as widgets and then add these widgets to RootPanel whenever required. and can control the position where it shows. For this I put the script into a native method and called this method on Click of a button. But I did not get success. Using it in html will be something like hard code and does not give user much flexibility.

Can Google Adsense be used with GWT
I have developed a web site using GWT1.5. I want to show Google Adsense on it. DO GWT have support for Google Adsense. Any comments/ updates in this regard will be highly appreciated.

Re: authentication in GWT
To logout from HTTP authentication use:
public void logout() {
HttpSession session = this.getThreadLocalRequest().getSession();
session.invalidate();
}
You can do this in your ServiceImpl class.
I kind of agree with Reinier, but might have used language that was
less strong.

GWT, Netbeans and debugging
I have been working on a GWT project with Netbeans and the client side debugging in hosted mode has stopped working. I created a test helloworld project from scratch and the debugging works fine there. I am using gwt4nb and I created another test project, copied over all my sources but used all new build.xml and configuration files. Still no joy. For my large project I have had to increase the memory to GWTShell, but cannot imagine why this would cause problems with debugging. I know that I am not giving much information on this problem, but... Anyone seen this? Anyone have a solution? Any suggestions? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
