I want to put a session with a text: "please wait" that ll be hidden all the time, except when a webservice is running.
I have a field to control show/hidden, and I try to set it to show when I use a afterChange and set to hide when the afterChange ends, but the show/hide only is "resolved" after all code (including call to webservice) in the afterChange runs. So the "please wait" dont is showed :/
Any one have a another solution to put a "please wait" while the code is running?
