This behavior occurs with version ext-4.1-pr1.
No problems with ext-4.0.2a / ext-4.0.7.

First time click on menus:

Attachment 28907

the application controller handle click this way:

Code:
,onItemClick:function(menuItem) {
    // other items handling
    
    switch(menuItem.action) {
        case 'elencoTipologieEnte':
            var lte = Ext.ComponentQuery.query('listaTipologieEnte')[0];
            if(lte && lte.length > 0 ) {
                lte.toFront(true);
            } else {
                lte = Ext.create('CpGev.view.tabelle.tipologie.ente.Lista',{
                     animateTarget: Ext.ComponentQuery.query('#btnTabelleTipologie')[0]
                });
                var mv = Ext.ComponentQuery.query('mainView > container')[1];
                mv.add(lte);
                lte.show();
            }
        break;
    }


    // other items handling


}
the list window is defined as:

Code:
Ext.define('CpGev.view.tabelle.tipologie.ente.Lista', {
     alias :'widget.listaTipologieEnte'
    ,extend: 'Ext.window.Window'
    ,height: 480
    ,iconCls: 'icon-tipologia-ente16'
    ,iconizedCls: 'icon-tipologia-ente32'    
    ,initComponent: function() {
        var me = this;
        me.editing = Ext.create('Ext.grid.plugin.CellEditing', {
             clicksToEdit: 1
        });
        me.items = [{
             columnLines: true
            ,columns: [{
                 dataIndex: 'id'
                ,sortable: true
                ,text: 'ID'
                ,width: 30
            }, {
                 dataIndex: 'descrizione'
                ,editor: {
                     allowBlank: false
                    ,selecteOnFocus: true
                    ,xtype: 'textfield'
                }
                ,flex: 1
                ,header: 'descrizione'
                ,itemId: 'descrizione'
                ,sortable: true
            }, {
                 dataIndex: 'note'
                ,editor: {
                     allowBlank: true
                    ,selecteOnFocus: false

                }
                ,flex: 1
                ,header: 'note'
                ,itemId: 'note'
                ,sortable: true
            }]
            ,dockedItems: [{
                items: [{
                     action: 'add'
                    ,iconCls: 'icon-add16'
                    ,id: 'aggiungiTipoEnte'
                    ,disabled: false
                    ,text: 'Nuova tipologia ente'
                }, {

                    ,disabled: true
                    ,iconCls: 'icon-delete16'
                    ,id: 'cancellaTipoEnte'
                    ,scope: this
                    ,text: 'Cancella tipologia ente'
                }, {
                     action: 'sync'
                    ,disabled: true
                    ,iconCls: 'icon-sync16'
                    ,id: 'syncTipoEnte'
                    ,scope: this
                    ,text: 'Sincronizza server'
                }]
                ,xtype: 'toolbar'
            }]
            ,id: 'gridTipologieEnte'
            ,multiSelect: true
            ,plugins: [me.editing]
            ,store: 'TipoEnte'
            ,viewConfig: { 
                deferEmptyText: true
                ,forceFit: true
                ,emptyText: '<font color="red"><b>Tabella tipologie enti</b></font>' 
                ,stripeRows:false
                ,trackOver: false
            }
            ,xtype: 'gridpanel'
        }];
        me.callParent(arguments);
    }
    ,layout: 'fit'
    ,title : 'Elenco tipologie enti'
    ,width: 640
});
as result I get:

something wrong with my code or it is a bug?

I'm blocked. Can't use the (good) speed improvements of ext-4.1-pr1.
