    Default 'beforesort' event is not fired by TreeStore

    REQUIRED INFORMATION



    Ext version tested:

    • Ext 4.1.1



    Browser versions tested against:
    • FF18.0.2



    DOCTYPE tested against:

    • ____



    Description:

    • Observe slow sorting on Tree Panel, debugging with firebug, found that events are not suspended on Ext.tree.View which suppose to per 4.1 docs.sencha.com
    • I am not even able to find 'beforeSort' event on TreeStore instance, neither 'onBeforeSort' function on Ext.tree.View
    • Is it something documented but never implemented?


    Steps to reproduce the problem:

    • using tree grid sample with firefox+firebug



    The result that was expected:

    • as documented, suspendEvents called on tree.view.store(node store) before sorting on tree, resumeEvents and refresh tree view after sorting



    The result that occurs instead:

    • events not suspended on tree.view.store, layout gets update on 'sort' event fired by each node



    Test Case:


    Code:
        <<insert working code to reproduce the report >>






    HELPFUL INFORMATION




    Screenshot or Video:

    • attached



    See this URL for live test case: http://




    Debugging already done:

    • none



    Possible fix:

    • register 'beforesort' event on TreeStore
    • before sort, fire 'beforesort' event on TreeStore
    • work around, override TreeStore



    Additional CSS used:

    • only default ext-all.css

    Operating System:

    • ________

    Using a newer release (4.1.3 to be specific) I added this to the treegrid.js example and it is working for me:

    Code:
            listeners : {
                beforesort : function() {
                    console.log('beforesort');
                }
            }

    this bug has huge performance impact on tree panel, any plan to apply the fix to evaluation version (currently it is 4.1.1a)?
