ExtJS 4 RowEditing disable edit on one column based on record

Question

I\'m implementing a grid panel with the four last columns editable for most of the rows. The problem is that I\'d like to be able to disable editing on, let\'s say the first one

Answer 1

(based on the previous example) an alternate way is to configure the editor's beforeedit listener:

listeners: {
    beforeedit: function(editor, context) {
        var form   = editor.getEditor().form;
        var field  = form.findField('column_name');
        var status = parseInt(context.record.data.status);
        if(status === 4){field.disable();} else {field.enable();}
    }
}
