It depends on your task. If it is related to validation you can
campare values in onValidate handler:
@OnEvent(value=EventConstants.VALIDATE, component="mySelect")
void validateMaySelect(MyValue newValue) {
if (!myValue.equals(newValue)) {
// your code here
}
}
Or you can use getter and setter method on the page/component:
public MyValue getMyValue() {
return myValue;
}
public void setMyValue(MyValue newValue) {
if (!myValue.equals(newValue)) {
// your code here
myValue = newValue;
}
}
