    Default TypeError: Cannot read property 'parentNode' of undefined

    TypeError: Cannot read property 'parentNode' of undefined


    Good morning from Valencia, Venezuela; and sorry for my poor english. I have two grids, one that is loaded into a panel (this panel is in a tab), and other that is loaded into another tab. Both are in a FormPanel, this FormPanel is in a Window that is called when I make double click from a record of a master grid. This master grid is called when I make click in an icon that is located on Web Desktop. The error is: "TypeError: Cannot read property 'parentNode' of undefined", and this occurs when I close the window that content the formPanel. I think that the grid is destroyed by the close instruction, and I can't use the property 'hide', because when I make double click in another record, the data is not loaded, and the task bar of the Web Desktop don't remove the item. Thanks in advance, I will return crazy with this issue...

    PS: Don't put the code, because when I comment the lines that show the grids into a formPanel, the app work fine.

    Not much information to go on...

    Can't you hide the window (closeAction:'hide') and reuse the window for the next record, e.g.

    Code:
    var win = Ext.getCmp('mywindow');
    if (!win) {
      win = new Ext.Window({
        id: 'mywindow',
        closeAction: 'hide',
        ...
      });
      win.render(Ext.getBody());
    }
    var form = win.find('itemId', 'myform'); // example - use your own method to locate the form in the window
    form.getForm().loadRecord(record);
    win.show();
