ok, I have a button & when clicking that button it will call this methodX
public void methodX(){
CheckBox cb=new CheckBox();
HandlerRegistration reg=cb.addClickHandler(new ClickHandler(){
@Override
public void onClick(ClickEvent event) {
// TODO Auto-generated method stub
int x=1;
}
});
if(reg!=null){
reg.removeHandler();
}
}
The above methoxX runs ok. There no error whatsoever when i click the
button 1 time or many times. However if I change the methodX a bit
public void methodX(){
CheckBox cb=new CheckBox();
HandlerRegistration reg=cb.addClickHandler(new ClickHandler(){
@Override
public void onClick(ClickEvent event) {
// TODO Auto-generated method stub
int x=1;
}
});
if(reg!=null){
reg.removeHandler();
}
///add these lines of code
if(reg!=null){
reg.removeHandler();
}
}
Now when clicking the button I got this error
Uncaught exception escaped
com.google.gwt.event.shared.UmbrellaException: Exception caught: redundant
remove call
at
com.google.gwt.event.shared.HandlerManager.fireEvent(HandlerManager.java:129)
Is there anyway to control this or this is Google bug?
