You are so right!
How about that: unhighlight only if I'm the last drawer of the
feature, and unhighlight to the previous render intent. The
implementation would look like this:
(1) the select feature control places a reference to itself in the
feature it is about to highlight (whether highlightOnly is set or not)
feature._drawer = this;
this.layer.drawFeature(feature, selectStyle);
(2) before highlighting a feature store in the feature it current renderIntent
feature._previousRenderIntent = feature.renderIntent;
(3) unhighlight only if I'm the last drawer of the feature
if(feature._drawer == this) {
this.layer.drawFeature(feature, feature._previousRenderIntent);
}
It looks better to me, tell me if this is flawed again.
Thanks for the collaboration on this Alexandre.
