    Vou responder a este email e ao outro que mandaste<br>
    <br>
    Nunca trabalhei com OSM, acho que e' uma classe que e' herdada de
    OpenLayers.Layer.XYZ portanto tera as mesmos options.<br>
    <a class="moz-txt-link-freetext" href="http://wiki.openstreetmap.org/wiki/OpenLayers_Simple_Example">http://wiki.openstreetmap.org/wiki/OpenLayers_Simple_Example</a><br>
    <br>
    Podes meter a layer onde quiseres sem grandes problemas, ate podes
    chegar a este ponto:<br>
    <br>
    map.addLayer(new OpenLayers.Layer.OSM());<br>
    <br>
    Eu nao sei o que estas a tentar fazer mas penso que queras que OSM
    seja a baseLayer ? Talvez isto funcione ?<br>
    <br>
    map.addLayer(new
    OpenLayers.Layer.OSM(options={'isBaseLayer':true}));<br>
    <br>
    Quanto ao erro:<br>
    <br>
    <br>
    <div role="listitem" class="errorTitle focusRow subLogRow "><span
        class="errorDuplication "></span><span aria-expanded="false"

        class="errorSource a11yFocus ">layer.div.className="olLayerDiv";layer...ContainerDiv.appendChild(layer.div);}<br>
        <br>
        o problema esta aqui:<br>
        <br>
        map.<b>addLayer</b>([wms_ruas, wms_base]);<br>
        <br>
        addLayer --&gt; Adiciona 1 layer e a funcao aceita um Layer
        Object <br>
        <br>
        No teu caso estas a mandar uma lista de layers <br>
        <br>
        Tens de usar o metodo addLayers que aceita uma array com layer<br>
        <br>
      </a><a

    E tudo por agora mais duvida ?! ^_^ <br>
