Spry.Widget.AutoSuggest

Question

I am using the Spry.Widget.AutoSuggest as part of another
object. I have the details VERY close, but am missing a small
detail somewhere, and while I think I've tried everything, I'm
still missing something.
In my init, I have the following code:
quote:
* Callbacks used for Predictive Search -------Fails
Spry.Widget.PredictiveSearch.prototype.regionCallback =
Object;
Spry.Widget.PredictiveSearch.regionCallback.prototype.onPostUpdate
= function(notifier, data)
alert("onPostUpdate called for " + data.regionID);
var typedText = this.predictiveSearch.typedTextField.value;
boldTextInChildDivs( data.regionNode, typedText );
this.setMatchIgnoreCase( typedText );
resetSessionTimeoutCheck();
self = this;
var regionCallback = this.regionCallback;
var suggestionsDiv = this.suggestionsDiv;
alert(self.suggestionsDiv)
Spry.Data.Region.addObserver( self.suggestionsDiv,
self.regionCallback );
When I type in the field, everything works as expected,
except that the suggestions div is not populated (it shows as an
empty div in firebug). The alert inside the region callback never
fires, so there is something wrong with how I am creating either
the addObserver, or the function itself. If I make this a function,
and use the 3rd parameter, AND make it a child of the window with a
unique name, it works fine... The idea was to try to make this a
little more like Spry.Widget.CollapsiblePanel in how the callbacks
are handled.
If you're wondering why I'm doing it this way, I am trying to
optimize some pages which use this widget several times per page,
and currently have it hard coded on the page (this is being pulled
into a separate javascript file.)
Thanks in advance.

Answer 1

The partial answer is that I was using incorrect syntax. I
started going through the SimpleAutosuggest, and found the
following:
quote:
Spry.Data.Region.addObserver(regionID, { onPostUpdate:
function(notifier, data) {
self.attachClickBehaviors();
Which was basically the syntax I was looking for, which
allows me to use the object notation instead of the function
notation, and call through an object that each autosuggest object
is tied to.
However, it brings me back to my original problem. I've gone
through the Region Observer Notifications documentation here:

... and in another place, I read that in a callback, you cannot
pass variables because it will run the call back immediately, and
not when you expect it to. That seems to be my problem, but
regardless of if I pass parameters, I get no call back when I
expect it. If I pass parameters, I get the call back immediately,
but not later, if I don't pass parameters, I never get the
callback.
It's got to be something dumb, but I don't see what it is,
and unfortunately, I have no way of putting the code outside our
firewall until it goes live. :(
Thank you for trying.
