Dear developers, I add a PropertyChangeListener to AsteriskChannel. In method propertyChange() I read the propertiy dtmfReceived. When a single digit, let's say '#' is pressed several times the method is called only one time. But I want the method to be called everytime so I came to the idea of reseting dimfReceived to null. But due to the visibility of AsteriskChannelImpl this is not possible. Is there any way to do that? I do not want to modify the original Code? Thank you for your supports -- Ngô Vi Hoài Anh Biedenkopfer Weg 13 60489 Frankfurt am Main 069 74 22 36 63 0172 53 97 0 82 |

Answer to myself,
Using reflection has worked out. But this seems to me a bit dirty. Is
there any more asterisk-java native way?
+++++
@Override
public void propertyChange(PropertyChangeEvent arg0) {
AsteriskChannel asteriskChannel = (AsteriskChannel)
arg0.getSource();
String chanId = asteriskChannel.getId();
logger.info(chanId+"::"+arg0.getPropertyName()+"::"+arg0.getOldValue());
logger.info(chanId+"::"+arg0.getPropertyName()+"::"+arg0.getNewValue());
// workaround to reset invisible field by default
try {
String fieldName = arg0.getPropertyName();
if(fieldName.startsWith("dtmf")) {
Class<?> c = asteriskChannel.getClass();
java.lang.reflect.Field field =
c.getDeclaredField(fieldName);
field.setAccessible(true);
field.set(asteriskChannel, null);
}
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchFieldException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

I'm not a project contributor. But I think it makes sense that
asterisk-java would invoke the listener for each distinct press. If it
doesn't, wouldn't a better approach be to write a patch for it instead
of using reflection?
