what do you have at line 478 of your ClientLayerReorder.php file?
I only see a comment at that line

  Subject: [Cartoweb-users] Show layers in a defined order

  Hi everyone.

  I'm trying to do a 2 in 1 action with Cartoweb: Show some layers in a special order. So it means i have to check some layers in the layers tree and reorder them. Finally i make the ajax call to make Cartoweb apply the changes.

  The problem is Cartoweb seems not to know the layers i just checked. Here's the error message.

version: 3.3.0 [$Revision: 1.2 $]
class:   CartocommonException
message:   Error [8, Undefined index:  1, /opt/cartoweb/cartoweb3/projects/aeag/plugins/layerReorder/client/ClientLayerReorder.php, 478]

  So here's the function i made to do this.

    function chargeVue() {    
        // Here i get the layers i need to show in a field of my form
        for (var i=0; i<$('selectVue').options.length; i++) {
          if ($('selectVue').options[i].selected ) {
            selectione = $('selectVue').options[i].value;
        // Here i check the layers i got in the layer tree
        var tabSel = $('vue_'+selectione).value.split(";");
        var tabOrdre = new Array();
        var celts = $('layersroot').getElementsByTagName('input');

        for (var j = 0; j < celts.length; j++) {
            if (!celts[j].checked && inArray(tabSel,celts[j].value)) {
                celts[j].checked = true;
                // Here i store the order of the layers in the layers tree
                celts[j].checked = false;
        // Here i fill an array with the new layers order
        var tabNewOrdre = new Array();
        for (j = 0; j < tabSel.length; j++) {
            // Ajoute l'indice de la couche dans tabOrdre
        $('layersReorder').value = tabNewOrdre.join(",");
        // Here i update the map

  Is there a way to achieve this without making 2 ajax calls (one to check the layers, the other to order them)?

  Thanks for your help
