Example Fade effect for data change?

Question

Is there an example of how to use the fade effect when
transitioning from one record to another in a dataset?
What I have now is causing a blinking. The old data fades
out, new data appears then fades in.
<script type="text/javascript">
<!-- // special effects - Fade in/out -->
var fadePOout = new Spry.Effect.Fade('PO',{duration: 1000,
from: 100, to: 0});
var fadePOin = new Spry.Effect.Fade('PO',{duration: 1000,
from: 0, to: 100});
function observerPO(notificationType, notifier, data) {
if (notificationType == "onPreLoad") {
fadePOout.start();
if (notificationType == "onPostLoad") {
fadePOin.start();
dsPO.addObserver(observerPO);
</script>

Yes, the example is what I want to happen. Am just not sure
it can work with a pagedview dataset as the master. Tried very hard
to follow your directions; Corrected the code in the
SpryEffects.js. Made the CSS entry for the 'PO' region to have
opacity:0. Copied your code and changed ds1 to my detail dataset
(dsPO) (also tried my master dataset, dsPOrders, out of
frustration). Changed the region name from 'description' to 'PO'
(which is the name of my region to fade in and out). Added
onclick="fadeOutContentThenSetRow('{ds_RowID}');" to the master
dataset record. (Yes, I added it. I still have no clue as to how
changes from the pagedview master dataset can update a detail
dataset, but it does.)
End result is the detail dataset appears as though the CSS
was not read. I know this because I can see spry:state="loading"
graphic. Then the data appears. It then disappears and fades in.
Clicking on a master dataset record repeats the above result.
Via Firebug am able to see that the function
fadeOutContentThenSetRow never runs. The function fadeInContent
runs several times. It appears to run through all events of the
data region twice (Accounting for why the data is seen
twice.)
