Thread: BufferedStore problem

    Default BufferedStore problem


    I am trying to use the BufferedStore. I have changed my store to Ext.Store.BufferedStore and set the leadingBufferZone config to true. The grid does not display the data, however when switching to and removing leadingBufferZone config, it works!

    I have tried this before and know it works, so I'm a little stuck. Here's my code...

    The View...

    Ext.define('Actions.view.activitylog.ActivityLog', {
        extend: 'Ext.grid.Panel',
        requires: [
        controller: 'activitylog',
        id: 'gridactivity',
        xtype: 'gridactivity',
        columns: [
            { text: 'Details', flex: 1, dataIndex: 'ActivityDetails', sortable: true }
        rowLines: false,
        columnLines: false,
        minHeight: 200,
        loadMask: true,
        selModel: {
            pruneRemoved: false
        multiSelect: true,
        viewConfig: {
            trackOver: false,
            emptyText: '<h3 style="text-align:center; margin-top:15px">There is no activity history</h3>'
    And Controller...

    Ext.define('Actions.view.activitylog.ActivityLogController', {
        extend: '',
        alias: 'controller.activitylog',
        init: function () {
            var me = this;
            var view = me.view;
            var configuration = Ext.getStore('storeConfiguration').getAt(0);
            // Activity log
            storeActivities = Ext.create('', {
                fields: ['ActivityDetails'],
                id: 'storeActivities',
                pageSize: 20,
                leadingBufferZone: 40,           
                proxy: {
                    type: 'odata',
                    url: configuration.get('spWebUrl') + "/_vti_bin/ListData.svc/Activity",
                    readUrl: configuration.get('spWebUrl') + "/_vti_bin/ListData.svc/Activity?$inlinecount=allpages",
                remoteFilter: true,
                autoLoad: true

    I'm not sure if it will solve this error but why do you have your store in the viewcontroller and not in the viewmodel?

    Good luck / E

    That's just my implementation which works when I switch to, so shouldn't be an issue really. Can you see anything which would cause this not to work, seems like a bug to me!
