Extjs 4.1 - Listerning in CellEditing plugin not working at second time

Question

i define a with plugin CellEditing like

Ext.define('MyExample', {
        extend: 'Ext.tree.Panel',   
        id: 'example',
        alias: 'example',
        ....
        plugins: [
            Ext.create('Ext.grid.plugin.CellEditing', {
                clicksToEdit: 1,
                listeners: {
                    beforeedit: function(plugin, edit){
                        alert('don't run second time');
                    }
                }
            })
        ],
        ...

And i have a when i click this button will call below window (this window has treeGrid above) 当我单击此按钮时将在窗口下方调用（此窗口上方有treeGrid）

Ext.create('Ext.window.Window', {
title: 'Phân xử lý',
modal:true,
height: 500
width: 500
layout: 'border',
...
item[
 {
  title: 'example',
  region: 'center',
  xtype: 'example', // that here
  layout: 'fit'
 }
]

Answer 1

The problem here is that you are using Ext.create inside the plugins array for the tree grid. This have the effect of creating it once and attaching the result adhoc to your defined class.

If you close the window, all the resources within the window are destroyed. The second time you instantiate the tree panel, the plugin is not there. Take a look at this fiddle : I see what your issue is. Take a look at http://jsfiddle.net/jdflores/E6Uss/1/

     {
        ptype : 'cellediting',
        clicksToEdit: 1,
        listeners: {
            beforeedit: function(plugin, edit){
                console.log('EDITOR');
                if (edit.record.get('block')) {
                    alert('this cell have been blocked');
                    return false;
                }
            }
        }
    }

You're recreating the window on every click of the button. This recreation may be messing with your configuration objects or destroying associations or references within them, or something similar. Try to reuse the window everytime by replacing your button code with something like:

    Ext.create('Ext.Button', {
        text: 'Click me',
        visible: false,
        renderTo: Ext.getBody(),

        handler: function(button) {
            if(!button.myWindow)
            {
                button.myWindow = Ext.create('Ext.window.Window', {
                   title: 'Example',
                   height     : 300,
                   width      : 500,
                   layout: 'border',
                   closeAction: 'hide',
                   items: [{            
                            region: 'center',
                            floatable:false,
                            layout:'fit',
                            xtype: 'example',
                            margins:'1 1 1 1'
                        }
                    ]
                 });
            }
            button.myWindow.show();
        }
    });

Maybe it needed complete the editing cell, try finish it:

...
beforeedit: function(plugin, edit){
     alert('don't run second time');
     plugin.completeEdit();
}

Sencha: CompleteEdit

I put together a working example here: http://jsfiddle.net/jdflores/6vJZf/1/

I think the problem with your column is that it's dataIndex is expecting that the editor value be a boolean type (because 'block' was set as datIndex instead of 'date'). I assume you are using the 'block' field just to identify which are blocked to be edited. I modified the fidle provided here: http://jsfiddle.net/jdflores/6vJZf/1/

       {
            text: 'Block Date',
            dataIndex: 'date',
            xtype: 'datecolumn',
            format: 'd/m/Y',
            editor: {
                xtype: 'datefield',
                allowBlank: true,
                format: 'd/m/Y'
            } 
        }
