Extjs 4.x Return value from Ext.window.window combobox to update selected records

[daviboysmith]

Firstly I am new to EXTJS and am stuck with this issue and no solution for weeks. Your help is much appreciated.

I have a grid with CheckboxModel. So a user can select x rows and click on button called "Update Status". This button should open a pop-up window with list of Statuses (Active, In-Active, Closed etc.) in a combobox and button for save and cancel. When user presses Save, update all selected rows/records with the selection value in the combobox, can close the window.
.....///
selModel: Ext.create('Ext.selection.CheckboxModel', {
listeners: {
selectionchange: function (sm, selections) {
Ext.ComponentQuery.query('#UpdateStatus')[0].setDisabled(selections.length == 0);
}
}

Here is some code I used to do the same thing. It change the status of selected record in grid.

This uses a remove table and sends the id's of the selected records to the server where the updating is handled

    // perform actual change to selected records
    on_change_status: function(item,event,status) {
        var selRows = this.grid.getSelectionModel().getSelection();
        if (selRows.length > 0) {

            var requests = [];
            for (var i = 0, rec; rec = selRows[i]; i++){
                requests.push({ id: selRows[i].data.id_request });
            }
            // ajax call to delete all id instead of multiple calls to store.remove
            Ext.Ajax.request({
                method: 'POST',
                url: 'index.php/requests/change_status/',
                params  : {
                    ids: Ext.encode(requests), // list of requests
                    status: status
                },
                success: function() {
                    // observable catches errors
                },
                failure: function() {
                    alert('AJAX FAILURE: Unable to change selected requests');
                }
            });

            // update view
            storeRequests.load();

        } else {
            alert('NOTICE: You must select a request to perform this action');
        }
    },

Scott.
