[OpenLayers-Dev] selectFeature's selectStyle cannot accept propertyStyle?

[Alexandre Dubé]

Hi,

   If you can narrow down which style properties are unique for each 
feature, instead of defining a unique style and use it as feature.style, 
you could define custom properties in the feature attributes to hold the 
unique values and use them in your context, as you do with ${type}.

   Here's a copy of the drawFeature method in Layer/Vector.js :
         if (typeof style != "object") {
             if(!style && feature.state === OpenLayers.State.DELETE) {
                 style = "delete";
             }
             var renderIntent = style || feature.renderIntent;
             style = feature.style || this.style;
             if (!style) {
                 style = this.styleMap.createSymbolizer(feature, 
renderIntent);
             }
         }

   So, the feature style is obtained in that order of priority :
    * feature.style
    * layer.style
    * feature.renderIntent

   In order to let the styleMap manage the feature style, you should 
avoid setting the feature.style directly.

   Using this method, your layer styleMap should contain both default 
and select keys in order to work properly, with select containing the 
additionnal label: "${type}" property set.

   You could try that and see how it goes.

HTH,

Alexandre
