I'm developing on a OpenLayers application which creates dynamic rules for a vector layer using the geostats library. I want to create these rules inside a simple loop through the number of classes. I'm pushing every rule to a array and add this array via stale.addRules(). In my opinion every rule has to be cloned before adding it to the array. The problem is, I am using a OpenLayers.Filter.Function in which the clone() function is not implemented yet (OpenLayers 2.12-rc4). How can I solve this?

At the moment, only the last rule gets visualized. It seems like the other rules get lost, due to the reference value issue...

My code looks like this:

for (var i = 0; i < numClasses; i++) {
    filter_x = new OpenLayers.Filter.Function({
            evaluate: function(attributes) {
                [...]
            }
        })
    var rule_x = new OpenLayers.Rule({
        filter: filter_x,
        symbolizer: { fillColor: colors[i],
                    fillOpacity: 0.5, strokeColor: "white"}
    });
    //var clone = filter_x.clone(); //returns null! clone is not implemented
    rules.push(rule_x)

}
style.addRules(rules);

Thank you for your help!
