    Default [2.1.0] Dynamically setting List to Grouped fails

    [2.1.0] Dynamically setting List to Grouped fails


    I have a list which is initially rendered ungrouped on a store with no grouper function defined.

    I use the following code to dynamically change this to a grouped list
    Code:
            
            var store = list.getStore();
    
            store.setGrouper(<grouper function>);
            list.setGrouped(true);
    This used to work in Touch 2.0.1 but now there's an error in Ext.dataview.List as headerIndices are not defined during the all to list.setGrouped(true);
    They are only updated on list.refresh();

    Suggested patch to Ext.dataview.List
    Code:
        updateGrouped: function(grouped) {
            var me = this,
                baseCls = this.getBaseCls(),
                cls = baseCls + '-grouped',
                unCls = baseCls + '-ungrouped';
    
    
            if (grouped) {
                // START OF PATCH
                if (!me.headerIndices){
                   me.findGroupHeaderIndices();
                }
                // END OF PATCH
                me.addCls(cls);
                me.removeCls(unCls);
                me.updatePinHeaders(me.getPinHeaders());
            }
            ......
    Sorry don't have time to post an example right now .. hope you can work with this...

    I just ran into this myself. BTW: the opposite (ungrouping) works:
    Code:
    list.setGrouped(false);

    This problem has been fixed for the next release. In the meantime you can use the following override:

    Code:
    Ext.define('Ext.ListGroupFix', {
        override: 'Ext.dataview.List',
        
        updateGrouped: function(grouped) {
            var me = this,
                baseCls = this.getBaseCls(),
                cls = baseCls + '-grouped',
                unCls = baseCls + '-ungrouped';
    
            if (grouped) {
                me.addCls(cls);
                me.removeCls(unCls);
                me.updatePinHeaders(me.getPinHeaders());
            }
            else {
                me.addCls(unCls);
                me.removeCls(cls);
                me.updatePinHeaders(null);
            }
    
            me.doRefresh();
        }
    });
    Thanks for the report.
