    Default [Ext 4.1.1] Ext.grid.Panel - Some events are not working if locked columns are used

    [Ext 4.1.1] Ext.grid.Panel - Some events are not working if locked columns are used


    REQUIRED INFORMATION

    Ext version tested:
    • Ext 4.1.1
    Browser versions tested against:
    • Chrome 21 (Windows)
    DOCTYPE tested against:
    • XHTML 1.0 STRICT
    Description:
    • If you register an event on Ext.grid.Panel (tested with "cellclick" [without any extension] and "filterupdate" [with Ext.ux.grid.FiltersFeature]), the event is not fired if a column is locked. It doesn't matter if you use .on() mehtod or use config listeners.
    Steps to reproduce the problem:
    • create Ext.grid.Panel and register a listener for "cellclick" event and lock a column via config
    • click in a cell
    The result that was expected:
    • the event is fired
    The result that occurs instead:
    • nothing happens
    Test Case:
    Code:
     Ext.Loader.setConfig({    enabled: true
    });
    
    
    Ext.Loader.setPath("F4H", "lib");
    
    
    Ext.require([
        'Ext.grid.*',
        'Ext.data.*',
        'Ext.util.*',
        'Ext.state.*',
        'F4H.*'
    ]);
    
    
    Ext.onReady(function() {
        Ext.QuickTips.init();

    HELPFUL INFORMATION
    Possible fix:
    • I created a workaround:
    Code:
    Ext.define( 'Fixed.Panel', {
        extend: 'Ext.grid.Panel',
        bothCfgCopy: [            'invalidateScrollerOnRefresh',

                'enableColumnMove',
                'enableColumnResize',
                'sortableColumns',
                'listeners',     // added this so that ExtJs is registering the listeners if injected by config
        ],
        
         normalCfgCopy: [         'verticalScroller', 
            'verticalScrollDock', 
            'verticalScrollerType', 
            'scroll'
        ],
        
       lockedCfgCopy: [ ],
    
        /// overridden to delegate events to locked/normal grid depending on the config above
        on: function( eventName, fn, scope, options ){
            // if lockedColumn feature is used, delegate listeners to normalGrid/lockedGrid
            if( this.lockable ){
                if( this.normalGrid && this._issetInCfgCopy( 'listeners', this.normalCfgCopy ) ){
                    this.normalGrid.on( eventName, fn, scope, options );
                }
                
                if( this.lockedGrid && this._issetInCfgCopy( 'listeners', this.lockedCfgCopy ) ){
                    this.lockedGrid.on( eventName, fn, scope, options );
                }
                
                return;
            }
            
            this.callParent( arguments );

         * 
         * @param {string} configSection The name of the config section.
         * @param {Array} specialConfig The special config: this.normalCfgCopy or this.lockedCfgCopy
         * @return {Boolean}
         */
        _issetInCfgCopy: function( configSection, specialConfig ){
            var config = Ext.Array.merge( this.bothCfgCopy, specialConfig );
            var i, ln;
            
            for( i = 0, ln = config.length; i < ln; i++ ){
                if( config[i] === configSection ){
