Looks like we can't reproduce the issue or there's a problem in the test case provided.

    Default Tree Store does not function with XML Reader

    Tree Store does not function with XML Reader


    Just as the title states the XML reader does not function with a Tree Store. I have yet to see any examples of XML being used with a Tree Store so this was probably over looked at some time. Anyway, below you will find all the files associated with the test case including a json data set that does function properly.

    That said, I have done some debugging already. There seems to be a number of issues but the most obvious will be a call to Ext,.DomQuery.isXml() inside of the XML Reader. The function being called does not exist. However, upon removing that the call to Ext.DomQuery.selectNode() issues the error that the second argument which is suppose to be a dom node does not have the method querySelectorAll. Upon further debugging dumping the data element to the console it is the root node defined in the tree store, not part of XML returned from the request. So it seems like when the request data is read the root level element of the XML file needs to be passed to the reader rather than the root defined in the store (most likely a object literal). That is as far as I have been able to get with it. Hope it helps.

    Thanks

    That is the most obvious issue but not the only one. The primary issue is that the root node is being passed to the reader rather than the XML document. So I urge you to reopen the thread.

Upon further debugging dumping the data element to the console it is the root node defined in the tree store, not part of XML returned from the request. So it seems like when the request data is read the root level element of the XML file needs to be passed to the reader rather than the root defined in the store (most likely a object literal). That is as far as I have been able to get with it. Hope it helps.

    Override the getRoot() function and the next error will become obvious.

    Code:
    Ext.define('TreeXmlBug.data.reader.XmlOverride',{
        override: 'Ext.data.reader.Xml',
        
        getRoot: function(data) {
            
            var nodeName = data.nodeName,
                root     = this.root;
    
            if (!root || (nodeName && nodeName == root)) {
                return data;
            } else {
                return Ext.DomQuery.selectNode(root, data);
            }
        }
        
    });
