I am experiencing an object undefined JavaScript error in my client side Seam
Remoting topic subscription callback function. The function is executed when
expected (when I publish an object message to the topic) but the message
object's value property is undefined. I have also tried to use the message's
object property which is also undefined. Can anyone point me to the right
direction?
Here is my JavaScript callback function:
| function subscriptionCallback(message) {
| var game = message.getValue();
| alert('Test: ' + game.getDescription());
| }
|
Here is my server side publishing code:
| private void publish(Game game) {
| try {
| topicPublisher.publish(topicSession.createObjectMessage(game));
| } catch (Exception ex) {
| throw new RuntimeException(ex);
| }
| }
|
Also, I notice an inconsistency in the chatroom example and the Contextual
Components documentation. The chatroom example uses the getValue() method to
retrieve the object from the message:
| function channelMessageCallback(message) {
| var ctl = getObject("channelDisplay");
|
| var actionDTO = message.getValue();
|
but the documentation instructs us to use the getObject() method:
anonymous wrote :
| A TextMessage contains the text value in its text field (or alternatively
call getText() on it), while an ObjectMessage contains its object value in its
object field (or call its getObject() method).
|
Thanks for your advise.
Jason
