Hi,
how can I unsubscribe a function from a message bus
(qx.event.message.Bus)?
Calling messageBus.unsubscribe("MESSAGE_TEXT") yields an error
("sub[msgName] is null")
Running the following in the Playground app also yields an error:
[CODE]
var messageBus = qx.event.message.Bus.getInstance();
var message = new qx.event.message.Message("TEST");
var myfunction = function() {
alert("Here I am");
}
messageBus.subscribe("TEST", myfunction);
messageBus.unsubscribe("TEST");
[/CODE]
Error:
playground.Application[p]: TypeError: k[l] is null
The combinations
[CODE]
messageBus.unsubscribe("TEST", myfunction);
//OR
messageBus.unsubscribe(myfunction);
[/CODE]
have no effect, the function gets called if the message is dispatched
anyway.
Am I doing something wrong or is this a bug?
Greetings,
Michael
