onUpdateEnd, onUpdateStart events for esri.layers.Layer

Hello All,

it appears that the onUpdateEnd event only fires for visible layers - is this by design?

Looking at the sample (, this will only work if all layers are visible.

Also, the onUpdateStart event does not behave as I would expect.  It does not fire when a layer is added to a Map like the onUpdateEnd does.  It does fire with zoom/pan, but only fires once even through there are multiple layers.  In this example I have four Layers added to a Map - two visible, two non-visible.  On a zoom/pan onUpdateEnd fires twice, onUpdateStart fires only once.

Am I missing something here?
