REQUIRED INFORMATION



Ext version tested:

• Ext 4.1.1

Browser versions tested against:

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

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

        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)?
