Here's something I've written that will work if you have 1 level of folders which each have a level of nodes under each of them that have matching ids. It takes the JSON before loading it into the store and then adds the parent id to the node id. The new read function isn't recursive and as far as I have used/tested only works for JSON, like above, that has the level as folders and the second level as nodes. Feel free to make your own recursive version should you need to. I used the code almost verbatim from 'Ext.data.JsonReader' (so I could step through the process easily) and then added in the method read from 'Ext.data.reader.Reader' and altered the read method. Edit: This might be a bit hacky, and may stop some functions working. The Ux: // JavaScript Document Ext.define('Ext.ux.data.reader.DupeIdTreeReader', { extend: 'Ext.data.reader.Reader', alternateClassName: 'Ext.data.DupeIdTreeReader', alias : 'read...

I have a working grid that is recieving data as json, where the json is matching the model. However in the real world, things aren't always this clean and controlled. We may end up with fields missing or entries with the wrong field name, or even extra fields that don't exist in the model. So if we want the process halted if the json does not match the model how can catch it? I extended the Extjs reader class, and then implemented to over-ridden methods from the original class, and sent errors to the console and replaced missing fields with a message. Ext.define('App.Reader', { extend: 'Ext.data.reader.Json', extractData: function(root) { var me = this, values = [], records = [], Model = me.model, i = 0, length = root.length, idProp = me.getIdProperty(), node, id, record; if (!root.length && Ext.isObject(root)) { root =...
