[OpenLayers-Users] Vector layer rendering with maxResolution: 'auto'

I have to set manually the resolutions and maxExtent for each layer
I have no more problem with vector rendering

map = new OpenLayers.Map('map');

var units = "m";
var scales = [100000, 50000, 25000, 10000, 5000, 2500, 1000, 500];
var resolutions = new Array(scales.length);
for (i=0;i<scales.length;i++) {
    resolutions[i] = scales[i] / (OpenLayers.INCHES_PER_UNIT[units] * 
OpenLayers.DOTS_PER_INCH);
}
var maxExtent = new OpenLayers.Bounds(208734.44346970832, 
2356190.841286027, 239182.1975747915, 2382407.4659272283);

baseLayer = new OpenLayers.Layer.WMS(
    "Cadastre",
    "/cgi-bin/mapserv.exe?map=c:/ms4w/apache/htdocs/maps/cideral.map&",
    {
        layers: "parcelle,batiment",
        format: "image/png",
    },
    {
        resolutions: resolutions,
        maxExtent: maxExtent,
        projection:"EPSG:27572",
        units: units,
        singleTile: true,
        transitionEffect: 'resize',
    }
);
map.addLayer(baseLayer);

vectorLayer = new OpenLayers.Layer.Vector(
    "Vector Layer",
    {
        resolutions: resolutions,
        maxExtent: maxExtent,
        projection:"EPSG:27572",
        units: units,
    }
);
map.addLayer(vectorLayer);
