clear tooltips for selected features?

I'm sure this is obvious... but I don't see it!

I have a FeatureLayer that I populate via its FeatureCollection. I trap the selectionComplete event and set tooltips for the selected features. (They're selected by IDs.) Each selection event creates a new selection set (with my tooltips), but the tooltips from the prior selection remain.

I've tried trapping the selectionClear event, but it doesn't seem to be called automatically; even when I call it myself the features collection seems to be null, so I can't iterate through it to remove the stale tooltips.

I'm sure there's got to be an easy way to do this...

Thanks,

There's not an easy way to handle this now. I'll enter an enhancement request to have FeatureLayerEvent.features populated for a "selectionClear" event.

In the meantime, try doing this when you get a "selectionComplete" event:

var featureLayer:FeatureLayer = event.featureLayer;
var selectedFeatures:Array = featureLayer.selectedFeatures;

for each (var graphic:Graphic in featureLayer.graphicProvider)
{
    if (graphic.toolTip && selectedFeatures.indexOf(graphic) == -1)
    {
        graphic.toolTip = null;
    }
}

Thanks, Dasa. I think that will be a very useful enhancement.
