How to reset Dataview's store data?

[chuckoh]

Hello guys. looks like a simple thing. But, I couldn't find a solution yet. Please help me.

I want to know how to reset Dataview's store data.

First off, my store data configuration is like: (initially, null)

Ext.define('App.view.FilterList', {
    extend: 'Ext.dataview.DataView',
    requires: ['App.view.FilterItem'],
    xtype: 'filter-list',


    config: {
        cls: 'filter-list',
        store: {
            fields: ['name'],
            data: null,
            sorters: 'name'
        },
        useComponents: true,
        defaultType: 'filter-item'
    }
});

On my controller, I insert some data on the fly while running my app like this:

panel.query('filter-list')[0].setData(somedata);

And, sometime later I want to reset the data to null so I can make the DataView list page blank.

I tried,

    onButtonTap: function(button, event) { // edit button in DataView list
        var listitem = button.getParent();
        var record = listitem.getRecord();
        var storeId = record.stores[0].getStoreId();
        var store = Ext.getStore(storeId);
        store.removeAll();
        :

I also tried:

        var panel = this.getTabPanel();
        var storeId = panel.query('filter-list')[0].getStore().getStoreId();
        var store = Ext.getStore(storeId);
        store.removeAll();
        :

The list was cleared with the above codes but, I got the following error

Uncaught TypeError: Cannot call method 'removeCls' of undefined DataView.js:597

What am I doing wrong? Can anyone suggest a solution for this?

It has nothing to do with the store, the error is within dataview. What version of ST2 are you using? I have seen issues where there was a selection and the data was changed causing an error but not sure if this is your issue or not.
