Store instances

[papaja]

I believe this has been duscussed before, but I'm simply unable to find answer elsewhere.

Store has nice feature that when I update it in one place, update is reflected on all components that are using it. However, is there a way to load 2 or more grids attached to stores with same definitions, but not same stores? E.g. is there a way to make every grid create it's own instance and use it so when I filter it or sort it, it is not reflected on another grid?

Just create a new instance of the store each time you create an instance of the grid.

In button click I have:

listInvoices: function(button) {
        il = new Ext.widget('invoicelist');
        il.show();
}

How do I create store when it is defined in grid's config?

Try to create instance in grid's initComponent method.

Do I have to "extend" grid in order to do it? In my case, I'm creating widget based on Window, and grid is element with store: myStore config.

You can provide store in initComponent of window.
