As described in the title, there is a bug using a particular combination of features.

The problem:

using 2 or more associated grids (by bind, parentGrid.selection.childItems) with checkboxmodel and locked column on the child grid the "select-all" checkbox will not work (checkbox injected in the header of grid) - it will work only with single row selection.


How to reproduce:

you can start using the example http://ift.tt/1oTZFia

but the second grid needs some change (red color) like this:



Code:



Ext.define('KitchenSink.view.binding.Associations', {
    extend: 'Ext.panel.Panel',
... the rest of the code ...
}, {
    title: 'Orders',
    xtype: 'grid',
    bind: '{customerGrid.selection.orders}',
    flex: 1,
    margin: '0 0 0 10',
    columns: [{
        locked: true, 
        text: 'Date', xtype: 'datecolumn', dataIndex: 'date', flex: 1, format: 'Y-m-d'
    }, {
        text: 'Shipped', xtype: 'booleancolumn', dataIndex: 'shipped',
        trueText: '✓', falseText: '-', align: 'center'
    }],
    viewConfig: {
        emptyText: 'No orders',
        deferEmptyText: false
    },
    selType: 'checkboxmodel'  
}]
...

NB: without locked column, it works.

Thank you
