Anyone knows how can I solve this?
See the code:
final EventListener dvn = new EventListener() {
public void onEvent(Event event)
throws Exception
{
ar.setValue( ar.getValue()+"..." );
}
};
try
{
Executions.getCurrent().getDesktop().enableServerPush(true);
Executions.activate(Executions.getCurrent().getDesktop());
new Thread(new Runnable()
{
public void run()
{
while (true)
{
try
{
Thread.sleep(1000);
dvn.onEvent(new Event("evnt"));
}
catch( Exception e )
{
}
}
}
}).start();
}
catch (Exception ex)
{
Logger.getLogger(LauncherApplicationPane.class.getName()).log(Level.SEVERE, null, ex);
}
Im getting this error:
"Components can be accessed only in event listeners"..

</device-config>public class Pane extends Div
{
final Label ar = new Label("asdfasdf");
Desktop _desktop;
public LauncherApplicationPane()
{
appendChild( ar );
_desktop = Executions.getCurrent().getDesktop();
new WorkingThread().start();
}
class WorkingThread extends Thread
{
public void run()
{
try
{
while (true)
{
_desktop.enableServerPush(true);
Executions.activate(_desktop);
try
{
ar.setValue(ar.getValue()+"...");
}
finally
{
Executions.deactivate(_desktop);
}
Threads.sleep(1000);
}
}
catch (DesktopUnavailableException ex)
{
System.out.println("The server push thread interrupted");
}
catch (InterruptedException e)
{
System.out.println("The server push thread interrupted");
}
}
}
}You'll have to enable serverPush before you can use it in a thread Please change LauncherApplicationPane() like this:
_desktop = Executions.getCurrent().getDesktop(); _desktop.enableServerPush(true);
Cheers, Maik
