Based on the example cell-editing.js I just defined a store and added a filter to the column "Light".
As long as I keep the 'id' in myStore everything is fine (line marked with xxx).

var myStore = Ext.create("", {
  fields: [
            {name:'type', type:'string'},
            {name:'name', type:'string'}          
  idProperty: 'type', // not working  
  autoLoad: false,
  idField: 'type',    // not working
  property: 'type',   // not working
//  data : [{type: '1',    name: 'Sunny'},{type: '2',    name: 'Rain'}]  // not working yyy
  data : [{id: '1',    name: 'Sunny'},{id: '2',    name: 'Rain'}]      // working xxx

    // create the grid and specify what field you want
    // to use for the editor at each header.
    var grid = Ext.create('Ext.grid.Panel', {
        store: store,
        features: [filters],        
        columns: [{
            id: 'common',
            header: 'Common Name',
            dataIndex: 'common',
            filter: {},              
            flex: 1,
            editor: {
                allowBlank: false
        }, {
            header: 'Light',
            dataIndex: 'light',
            width: 130,
            filter: {
                type: 'list',
                dataIndex: 'light',
                labelField : 'name',
                //idField: 'type',      // not working
                //valueField: 'type',   // not working
                value: 'type',        // not working
                store: myStore
When selecting "Rain" in the column "Light" I will get a request filled with:
filter [{"type":"list","value":["2"],"field":"light"}]
Everything is fine, but when using the definition with the field 'type' (line marked with yyy) I get
filter [{"type":"list","value":[null],"field":"light"}]

What do I have to tell my filter that he will recognize the field 'type'?
The lines marked with "not working" I have already tried. My Extjs version is 4.1.1
