REQUIRED INFORMATION




Ext version tested:

• Sencha Touch 2.1rc1

Browser versions tested against:

• ____
• Chrome 23

DOCTYPE tested against:

• html

Description:

• Ext.mixin.Selectable - Cannot update store with new store as null (i.e. remove the existing store).

Steps to reproduce the problem:

• Create a dataview
• Set a store for a dataview using useStore
• Try to remove the store by calling set store and passing it null

The result that was expected:

• The store is removed from the view

The result that occurs instead:

• An error occurs because Selectable tries to remove event listeners from the new store

Test Case:

Ext.Viewport.add({
    xtype   : 'dataview',
    itemTpl : '{test}',
    store   : {
        fields : ['test'],
        data   : [
            { test : 'foo' }
        ]
    },
    items   : [
        {
            xtype   : 'button',
            docked  : 'top',
            text    : 'setStore',
            ui      : 'confirm',
            handler : function(btn) {
                var dv = btn.up('dataview');

                dv.setStore(null);

                console.log(dv.getStore);
            }
        }
    ]
});

I added a test case for this report.

IMO a DataView should always have a store but it shouldn't throw an error. The error is actually in the Selectable mixin
