Problem with cell editor in custom menu

[eevee]

Hi!
I'm having some problems with 4.1.
I have a custom menu contining a grid with cell editor plugin.
When I click on the editor, menu lost focus and is closed...
the result is the editor, alone, on the page....

Please help me...

You will need to provide code to get help. Since this is custom component, it may take some time for someone to have a look at this.

Have you traced through the code with FireBug/Developer Tools to see what is going on in the call stack?

Regards,
Scott.

Thanks for quick reply, here is my code:
grid:

[...]
{
        text: "${_('Labels')}",
        menu: {
            xtype: 'menu',
            plain: true,
            forceLayout: true,
            width: 255,
            layout: 'vbox',
            items: [{
                xtype: 'labelmanager'
            }]
        }
    }
[...]

Menu:

Ext.define('LabelManager',{
    extend: 'Ext.container.Container',
    alias: 'widget.labelmanager',
    initComponent: function(){
        this.callParent();
        [...]
        var labelTable = new LabelTable();
        this.add(labelTable);
});

LabelTable:

Ext.define('LabelTable', {
    extend: 'Ext.grid.Panel',
    store: new LabelsStore(),
    plugins: [
         Ext.create('Ext.grid.plugin.CellEditing', {
             clicksToEdit: 1
         })
    ],
    columns: [{
        width: 130,
        dataIndex: 'title',
        editor: {
            allowBlank: false,
            xtype: 'textfield'
        }
    }
});
