Re: debugging doesn't work with -noserver
Are you trying to debug code with in module.client.* package or code out side of that module (Serer code)? If you want to debug code out side of module.client.* package, you need to start server in debug mode, if its in module.client.* package hosted mode will stop at the specified breakpoint.

Communication from GWT Module (main application window) to new child Window and vice versa
Hi,
I am creating a child Window using Window.oper("Url",...);
I need:
1 - a handler of this child window to close it from my GWT module code
2 - In child window need a handler of GWT module (main application
window) to call some functionality in main application
Over here I think I need to get parent handler
using window.handler from child window , get the gwt module div, and
then call GWT Function. But I don't have any idea on how to do it as
of now.
Any suggestions, thoughts and sample will be appreciated.
Thanks,
Bakul.

Re: FlexTable issues
Hi,
Set the name of textbox as an id of the record (or DTO, whatever you
call it).
and then:
textBox.addKeyboardListener(new KeyboardListenerAdapter() {
public void onKeyPress(Widget sender, char keyCode, int
modifiers) {
if (keyCode == (char) KEY_TAB){
// TextBox.cancelKey() suppresses the current keyboard
event.
String recordId = ((TextBox)sender).getName();
// call the service with this id and on success update the
row
}
}
});
Hope it should work.

Re: onTabSelected change the TabBar widget
try adding image on tab bar and then change the url of image on tab
change.
Like:
Image[] images = new Image[n];
images[0] = new Image();
img1.setURL("active.png");
tabBar.addTab(img1);
images[1] = new Image();
images[1].setURL("inactive.png");
tabBar.addTab(images[1]);
and so on for rest of the tab.
and then on tabChange:
public void onTabSelected(SourcesTabEvents bar, int index) {
images[index].setURL("active.png");
//set url of other images to 'inactive.png'
}

Re: fileupload not submitting
Hi,
I doubt about the form's action URL
Can you check the action value by
Window.alert(GWT.getModuleBaseURL() + "ImageUpload.do");
on click of button.
Let me know how it goes.

Re: Remote exception cause is lost during serialization
We are using the following approach.
1 - On serverside, MyException is generated as we generate any other
exception
2 - On Frontend, get the message using myExcepiton.getExcMessage();
Let me know if it help.
+Bakul+
public class MyException extends Exception implements IsSerializable
{
private static final long serialVersionUID = -3821801999548017773L;
private String excMessage;
public MyException () {
}
public MyException (String message) {
super(message);
excMessage = message;
}
public MyException (Throwable cause) {
super(cause);
}
public MyException (String message, Throwable cause) {
super(message, cause);
excMessage = message;
}
public String getExcMessage(){
return excMessage;
}
}

Re: FlexTable odd behavior
Can you post code or sample of the code?
FlexTable table = new FlexTable();
table.setText(0,0,"hello");
table.setWidget(0,1, new Label("World");
table.setWidget(0,2, new TextBox());
perfectly works for me.

Re: Getting continued feedback on the state of a RPC call
I think its an issue of threading on server side.
This is how it works for me !!! By clicking on button "Get Service
message".
Let me know if it works for you.
+Bakul Kumar+
//Client side code :
public class POC implements EntryPoint {
Label lblMessage;
Timer timer = new Timer() {
public void run() {
StockServiceAsync service = new StockServiceRPC()
.getStockServiceAsync();
service.getMessage(new AsyncCallback(){
public void onSuccess(String result) {
lblMessage.setText("Comp Message : " +
result);
}
public void onFailure(Throwable caught) {
Window.alert("Call Failed on
Server");
}
});
};
};
public void onModuleLoad() {
Image img = new Image(
"http://code.google.com/webtoolkit/logo-185x175.png";);
Button button = new Button("Click me");
button.addStyleName("pc-template-btn");
img.getElement().setId("pc-template-img");
VerticalPanel vPanel = new VerticalPanel();
vPanel.setWidth("100%");
vPanel.setHorizontalAlignment(VerticalPanel.ALIGN_CENTER);
vPanel.add(img);
vPanel.add(button);
Button serviceButton = new Button("Get Service Message");
vPanel.add(serviceButton);
serviceButton.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
timer.scheduleRepeating(1000);
StockServiceAsync service = new
StockServiceRPC()
.getStockServiceAsync();
//This one do the job of setting the
entry point for RPC call
service.longComputation(new
AsyncCallback() {
public void onSuccess(String result) {
timer.cancel();
Window.alert("Long Comp Message
: " + result);
}
public void onFailure(Throwable caught)
{
timer.cancel();
Window.alert("Call Failed on
Server");
}
});
}
});
lblMessage = new Label("Message");
vPanel.add(lblMessage);
// Add image and button to the RootPanel
RootPanel.get().add(vPanel);
// Create the dialog box
final DialogBox dialogBox = new DialogBox();
dialogBox.setText("Welcome to GWT!");
dialogBox.setAnimationEnabled(true);
Button closeButton = new Button("close");
VerticalPanel dialogVPanel = new VerticalPanel();
dialogVPanel.setWidth("100%");
dialogVPanel.setHorizontalAlignment(VerticalPanel.ALIGN_CENTER);
dialogVPanel.add(closeButton);
closeButton.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
dialogBox.hide();
}
});
// Set the contents of the Widget
dialogBox.setWidget(dialogVPanel);
button.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
dialogBox.center();
dialogBox.show();
}
});
}
}
Server side code
public class StockServiceImpl extends RemoteServiceServlet implements
StockService {
private static final long serialVersionUID = 1L;
String message;
public StockPrice getPrices(String[] symbols) {
return new StockPrice("LEH", 0.0);
}

try {
Thread.sleep(2000);
} catch (InterruptedException e) {

}
}
return "BK Rocks !!!, Calculation Completes";
}
public String getMessage(){
final StringBuffer
