Is there a way to catch an after expand event on tree (dojo 1.0.2) nodes ?
So far i tried to connect to onEnd event

_setChildren: function(/* Object[] */ childrenArray){
...
if(this.containerNode && !this._wipeIn){
	this._wipeIn = dojo.fx.wipeIn({node: this.containerNode, duration: 150});
	this._wipeOut = dojo.fx.wipeOut({node: this.containerNode, duration: 150});

        // here i try to connect to _afterExpand
	dojo.connect(this._wipeOut, "onEnd", this, "_afterExpand"); 
}
...
}
_afterExpand: function(){
// do somethimg
},
