Hello, I m searching to terminate execution of a handler when I select another handler from a dojomenu.

If I m  running somehting and I m waiting to see a  message and suddenly choose another handler

the message will show up in the next handler which is something I want to avoid.

Thanks in advance!

You could create a global variable and store the service name or other value then in the callback function test the value to ensure it is the service expected for this callback function.  As such, if another service is called from the dojomenu it will register a new service name or key so that when the first service's callback function is executed the value is tested and no longer "current" and callback function logic is not performed.
