[CLOSED] GridPanel Selected Items Limit

[ptrourke]

Another case where I'm probably just missing something obvious ...

Is there a practical limit as to how many items in a grid panel can be selected at one time? I'm stress testing my application, which has a grid panel with a store on it. I am using something like this

function DeleteSelection() {
    var selectedItemsList;
    selectedItemsList = App.MyGridPanel.getRowsValues({ selectedOnly: true});
    Ext.each(selectedItemsList, function(item){
        myRecord = App.MyStore.getAt(App.MyStore.findExact("MyID",item.MyID));
        App.MyStore.remove(myRecord)
    });
    App.MyStore.commitChanges();
}

to remove selected items from a store like this:

<ext:GridPanel ID="MyGridPanel" runat="server" ClientIDMode="Static" AutoScroll="true" MaxHeight="300" Title="My Items" ContextMenuID="MyContextMenu" StoreID="MyStore">
    <ColumnModel>
        <Columns>
             <ext:Column runat="server" ID="MyIDColumnName" DataIndex="MyID" />
        </Columns>
    </ColumnModel>
    <SelectionModel>
        <ext:RowSelectionModel runat="server" ID="MySelectionModel" Mode="Multi" />
    </SelectionModel>
    <BottomBar>
        <ext:Toolbar runat="server">
            <Items>
                <ext:Button runat="server" ID="DeleteButton">
                    <Listeners>
                        <Click Fn="DeleteSelection" />
                    </Listeners>
                </ext:Button>
            </Items>
        </ext:Toolbar>
    </BottomBar>
</ext:GridPanel>

When I have about 350 items in the grid panel, and try to select a large fraction of them (usually around 40 or so), I start seeing anomalies in how the selection is highlighted. I'm also having trouble selecting the last item in the grid.

Am I missing something obvious?

Thanks!
