Hi Alexandre If you want your vector layer to be visible only for a subset of the base layer's resolutions you should set maxResolution and/or minResolution in your vector layer options.
If you pass an array of resolutions to the vector layer, you can end up with vectorlayer.resolutions[i] != baselayer.resolutions[i], where i is any index of the vector layer's resolutions array. And I think you are hitting the above case, which is making the cluster strategy doesn't behave as you expect it to. So I don't see anything wrong with the cluster strategy relying on this.layer.getResolution. I'd really like to hear what others think about that.
