    Default Answered: NestedList goes to root node after dynamic node load

    Answered: NestedList goes to root node after dynamic node load


    I have very large document tree. In order to use it I use dynamic node load feature. But, after node successfully loaded to the list I end up getting back to the root node. If the node already in memory I can navigate to it without problems.

    The following code I use to load:
    Code:
    Ext.define('BpolMobile.model.DocumentList', {
        extend: 'Ext.data.Model',
        config: {
            fields: [
                {name: 'text', type: 'string'}
            ]
        }
    });
    
    .....
    {
        xtype: 'nestedlist',
        id: 'nestedList',
        store: {
            type: 'tree',
            id: 'NestedListStore',
            model: 'BpolMobile.model.DocumentList',
            defaultRootProperty: 'children',
            nodeParam: 'nodeId',
            root: {},
            proxy:
            {
                method: 'GET',
                type: 'ajax',
                url: '/mobile/ajax/DocumentList.svc/GetDocumentList',
                autoLoad: true,
                extraParams:
                {
                    loginToken: BpolApp.getInstance().loginToken
                }
            }
        },
         displayField: 'text',
    },
    /mobile/ajax/DocumentList.svc/GetDocumentList return the list:
    Code:
    [
        {
            "children": null,
            "id": 3668833,
            "leaf": false,
            "text": "!Revisions_test"
        },
        {
            "children": null,
            "id": 3669207,
            "leaf": false,
            "text": "!Revisions_test2"
        }
    ]
    When I tap to the !Revisions_test, proper request is issued and the result data applied correctly. But I'm end up returning to the root list, because NestedList::onStoreLoad fired each time child node loaded

    Code:
        onStoreLoad: function(store) {
            this.setMasked(false);
            this.fireEvent('load', [this, Array.prototype.slice.call(arguments)]);
            this.goToNode(store.getRoot());
        },
    The last line leads me to the root node.

    I suspect, that onStoreLoad should be fired only once. Could you please explain this behaviour? Maybe I do something wrong?

  2. You should try with 2.0.1 RC, the onStoreLoad has changed a bit that will most likely help you here.
