just installed glass mapper on a new Sitecore 8.1 solution and as soon as I loaded up the site I keep getting the following error - more details in screenshot.

Any thoughts?

Method not found: 'Boolean Glass.Mapper.ExtensionMethods.HasValue(System.String)'.

enter image description here

I guess you refferenced a wrong Glass.Mapper.dll from a old version of GlassMapper

Can you check if you have this method 

  /// <summary>
/// Indicates whether the specified string has a value, i.e. Not null or empty
/// 
/// </summary>
public static bool HasValue(this string target)
{
  return !ExtensionMethods.IsNullOrEmpty(target);
}

inside class Glass.Mapper.ExtensionMethods

I checked on GlassMapper vers 4.0.5

  • thanks for that - i had it all installed through the Nuget Package manager thinking it's the latest version but it wasn't! – Daniel Nov 30 '15 at 15:50
