Rails 2.3.2 + Google Email App + ActionMailer

Today I have problem while sending mail via Google Email App which raises exception

Net::SMTPAuthenticationError: 535-5.7.1 Username and Password not accepted. Learn more at

from /usr/local/lib/ruby/1.8/net/smtp.rb:942:in `check_auth_response'
from /usr/local/lib/ruby/1.8/net/smtp.rb:733:in `auth_plain'
from /usr/local/lib/ruby/1.8/net/smtp.rb:725:in `send'
from /usr/local/lib/ruby/1.8/net/smtp.rb:725:in `authenticate'
from /usr/local/lib/ruby/1.8/net/smtp.rb:566:in `do_start'
from /usr/local/lib/ruby/1.8/net/smtp.rb:525:in `start'

The problem was in incorrect password that I entered before at my browser. After that Google wants captcha. To disable captcha go to https://www.google.com/a/[your domain].com/UnlockCaptcha and unlock captcha request.

Are you tired to create DataTemplateSelector? Use GenericDataTemplateSelector!

Programming using WPF is a very cool programming. But sometimes WPF framework upsets of absence some useful functionallity. One of them is creating DataTemplateSelector directly in xaml. Here is the code of GenericDataTemplateSelector which can be defined in xaml:

public class GenericDataTemplateSelector : DataTemplateSelector

    {

        public DataTemplateSelectorItem[] DataTemplateSelectorItems { get; set; }

        public override DataTemplate SelectTemplate(object item, System.Windows.DependencyObject container)

        {

            if (item != null && DataTemplateSelectorItems != null)

            {

                foreach(var selectorItem in DataTemplateSelectorItems)

                {

                    var value = Reflector.GetValue(item, selectorItem.PropertyName);

                    if (selectorItem.Value.Equals(Convert.ToString(value)))

                        return selectorItem.Template;

                }

            }

            return null;

        }

    }

    public class DataTemplateSelectorItem

    {

        public string PropertyName { get; set; }

        public string Value { get; set; }

        public DataTemplate Template { get; set; } 

    }

Reflector is static class which uses ferlection to retrieve value of property.

Now you can define custom DataTemplateSelector in xaml:

<fx:GenericDataTemplateSelector x:Key="executionStatusSelector">

        <fx:GenericDataTemplateSelector.DataTemplateSelectorItems>

            <fx:DataTemplateSelectorItem PropertyName="ExecutionStatusID" Value="0">

                <fx:DataTemplateSelectorItem.Template>

                    <DataTemplate>

                        <Image Source="{StaticResource greenBulletImageSource}"/>

                    </DataTemplate>

                </fx:DataTemplateSelectorItem.Template>

            </fx:DataTemplateSelectorItem>

            <fx:DataTemplateSelectorItem PropertyName="ExecutionStatusID" Value="1">

                <fx:DataTemplateSelectorItem.Template>

                    <DataTemplate>

                        <Image Source="{StaticResource orangeBulletImageSource}"/>

                    </DataTemplate>

                </fx:DataTemplateSelectorItem.Template>

            </fx:DataTemplateSelectorItem>

            <fx:DataTemplateSelectorItem PropertyName="ExecutionStatusID" Value="2">

                <fx:DataTemplateSelectorItem.Template>

                    <DataTemplate>

                        <Image Source="{StaticResource blackBulletImageSource}"/>

                    </DataTemplate>

                </fx:DataTemplateSelectorItem.Template>

            </fx:DataTemplateSelectorItem>

    </fx:GenericDataTemplateSelector>
