Ext version tested:

  • Ext 4.1.1

Browser versions tested against:
  • FF18.0.2

DOCTYPE tested against:

  • ____


  • 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
  • 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 store) before sorting on tree, resumeEvents and refresh tree view after sorting

The result that occurs instead:

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

Test Case:

    <<insert working code to reproduce the report >>

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
