[Users] TreePanel control doesn't seem to be updating layers when I move them

[Andrew Stewart]

Yes the other functions are working. Based on Andreas's advice I added  enableDD: true to each LayerContainer control and now the individual layers in each group will actually work with moving them and changing the order, however the actual groups of layers themselves do not do anything if I move them around. My Code looks like this if it helps - I have many LayerContainers declared but only one showing here, thanks again for all the help everyone!



     var layerlist_Orthos = new GeoExt.tree.LayerContainer({
        text: 'Ortho Images',
        layerStore: mapPanel.layers,
        leaf: false,
        enableDD: true,
        expanded: false,
        loader:
        {
            filter: function(record)
            {
                var myarr = new Array();
                myarr[0] = record.get("layer").name.indexOf("2010 Ortho Image");
                myarr[1] = record.get("layer").name.indexOf("2006 Ortho Image");
                myarr[2] = record.get("layer").name.indexOf("2004 Ortho Image (No Color)");
                myarr[3] = record.get("layer").name.indexOf("2004 Ortho Image (Color)");
                myarr[4] = record.get("layer").name.indexOf("2001 Ortho Image");

                if(myarr[0]==-1 && myarr[1]==-1 && myarr[2]==-1 && myarr[3]==-1 && myarr[4]==-1)
                {
                return false;
                }
                else
                {
                return true;
                }
            }
            }
        });


        //declare root tree node
        var layerRoot = new Ext.tree.TreeNode({
            text: "All Legend Items",
            expanded: true
            });

       //add children to root node
       layerRoot.appendChild(layerList_Labels)
       layerRoot.appendChild(layerlist_AOI)
       layerRoot.appendChild(layerlist_Trails)
       layerRoot.appendChild(layerlist_Footprints)
       layerRoot.appendChild(layerlist_LegalFabric)
       layerRoot.appendChild(layerlist_ParcelFabric)
       layerRoot.appendChild(layerlist_Base)
       layerRoot.appendChild(layerlist_Orthos)



        var layerTree = new Ext.tree.TreePanel({
        title: '',
        renderTo: 'legend',
        root: layerRoot,
        enableDD: true,
        applyLoader: true,
        rootVisible: false
        });

}

Do the other functions work, like turning layers on and off?
I don't recall doing anything special to make the drag and drop work and it looks like you have it enabled.
Have you checked for javscript errors?

 I am trying to make my TreePanel / LayerContainers actually move the openlayers around when I move them in either their specific groups or in the groups themselves. I have tried experimenting by moving layers up and down (using drag and drop) but it does not seem to have any effect. Am I missing some extra code to make this possible? Thanks for advice.



 //declare root tree node

var layerRoot = new Ext.tree.TreeNode({

text: "All Legend Items",

expanded: true

});

//add children to root node

layerRoot.appendChild(layerList_Labels)

layerRoot.appendChild(layerlist_AOI)

layerRoot.appendChild(layerlist_Trails)

layerRoot.appendChild(layerlist_Footprints)

layerRoot.appendChild(layerlist_LegalFabric)

layerRoot.appendChild(layerlist_ParcelFabric)

layerRoot.appendChild(layerlist_Base)

layerRoot.appendChild(layerlist_Orthos)

var layerTree = new Ext.tree.TreePanel({

title: '',

renderTo: 'legend',

root: layerRoot,

enableDD: true,

applyLoader: true,

rootVisible: false

});
