Hi, I try use BrowserField and BrowserFieldErrorHandler to notify error message to user if  something wrong like code below :

public class BrowserScreen extends MainScreen {
	private BrowserField browserField;
	private BrowserFieldConfig browserFieldConfig;
	private ButtonField okButton;
	
	public BrowserScreen() {
		okButton = new ButtonField("Go");
		okButton.setChangeListener(new FieldChangeListener() {
			
			public void fieldChanged(Field field, int context) {
				browserField.requestContent("http://www.google.com");
			}
		});
		
		add(okButton);
		
		ConnectionFactory connFactory = createCustomConnectionFactory();
		
		
		browserFieldConfig = new BrowserFieldConfig();
		browserFieldConfig.setProperty(BrowserFieldConfig.CONNECTION_FACTORY, connFactory);
		
		browserField = new BrowserField(browserFieldConfig);
		
		browserField.getConfig().setProperty(BrowserFieldConfig.ERROR_HANDLER, new MyBrowserFieldErrorHandler(browserField));
		
		add(browserField);
		
	}
	
	private void displayError(String message){
		synchronized (Application.getEventLock()) {
			Dialog.ask(Dialog.OK, message);
		}
	}
	
	private ConnectionFactory createCustomConnectionFactory(){
		ConnectionFactory factory = new ConnectionFactory();
		factory.setConnectionTimeout(5000);
		
		return factory;
	}
	
	private class MyBrowserFieldErrorHandler extends BrowserFieldErrorHandler {	
		public MyBrowserFieldErrorHandler(BrowserField bf) {
			super(bf);
		}
		
		public void displayContentError(String url, String errorMessage) {
			displayError(errorMessage);
		}
		
		public void displayContentError(String url, InputConnection connection, Throwable t) {
			displayError(t.getMessage());
		}
		
		public void requestContentError(BrowserFieldRequest request, Throwable t) {
			displayError(t.getMessage());
		}
		
		public void navigationRequestError(BrowserFieldRequest request, Throwable t) {
			displayError(t.getMessage());
		}
		
		public BrowserField getBrowserField(){
			return super.getBrowserField();
		}
	}	
}

First,, click OK button and can access google with properly, Try to simulate error condition with pull out LAN cable, click some link in google site. I got error Uncaught: InterruptedIOException, click continue and show Dialog box "Local connection timeout after ~5000"

Question is how to eliminate InterruptedIOException Error and only show Error Message Local connection timeout after ~5000

Thanks
