Request: Adding handlers that only fire once

[karga]

Hi,

I'm often in need of an event handler, that only fires once and then kills itself.. I'm using something like this

function fnLoad() {
//Load functionality
objTreeLoader.removeListener('load',fnLoad)
}
objTreeLoader.addListener('load',fnLoad)


Is it possible to to this in any other (simpler) way? Otherwise I would like to make this a request :)

Read the DOCUMENTATION for addListener!!!!!!!

Woops, my bad :)

For others:

single : BooleanTrue to add a handler to handle just the next firing of the event, and then remove itself.
