对于 ux/form/ItemSelector.js 文件 中的**set**Value() 函数：

4.1版本的问题：

当将左边所有选项添加到右边时，用**get**Value()取值时取不到最后一项。

4.2版本中的为：

setValue: function(value) {
            var me = this,
                fromField = me.fromField,
                toField = me.toField,
                fromStore = fromField.store,
                toStore = toField.store,
                selected;
    
            // Wait for from store to be loaded
            if (!me.fromStorePopulated) {
                me.fromField.store.on({
                    load: Ext.Function.bind(me.setValue, me, [value]),
                    single: true
                });
                return;
            }
    
            value = me.setupValue(value);
            me.mixins.field.setValue.call(me, value);
    
            selected = me.getRecordsForValue(value);
    
            // Clear both left and right Stores.
            // Both stores must not fire events during this process.
            fromStore.suspendEvents();
            toStore.suspendEvents();
            fromStore.removeAll();
            toStore.removeAll();
    
            // Reset fromStore
            me.populateFromStore(me.store);
    
            // Copy selection across to toStore
            Ext.Array.forEach(selected, function(rec){
                // In the from store, move it over
                if (fromStore.indexOf(rec) > -1) {
                    fromStore.remove(rec);
                }
                toStore.add(rec);
            });
    
            // Stores may now fire events
            fromStore.resumeEvents();
            toStore.resumeEvents();
    
            // Refresh both sides and then update the app layout
            Ext.suspendLayouts();
            fromField.boundList.refresh();
            toField.boundList.refresh();
            Ext.resumeLayouts(true);        
        },

4.2版本中的为（注：4.2版本有些也是上面代码）：

setValue: function(value){
            var me = this,
                fromStore = me.fromField.store,
                toStore = me.toField.store,
                selected;
    
            // Wait for from store to be loaded
            if (!me.fromField.store.getCount()) {
                me.fromField.store.on({
                    load: Ext.Function.bind(me.setValue, me, [value]),
                    single: true
                });
                return;
            }
    
            value = me.setupValue(value);
            me.mixins.field.setValue.call(me, value);
    
            selected = me.getRecordsForValue(value);
    
            Ext.Array.forEach(toStore.getRange(), function(rec){
                if (!Ext.Array.contains(selected, rec)) {
                    // not in the selected group, remove it from the toStore
                    toStore.remove(rec);
                    fromStore.add(rec);
                }
            });
            toStore.removeAll();
            Ext.Array.forEach(selected, function(rec){
                // In the from store, move it over
                if (fromStore.indexOf(rec) > -1) {
                    fromStore.remove(rec);     
                }
                toStore.add(rec);
            });
        },
