Dynamics CRM 2011 plugin set custom field value

Question

I have Dynamics CRM 2011 plugin (retrieve, post-action) which should simply set the value of custom field when retrieving Contact entity:

    public void Execute(IServiceProvider serviceProvider)
    {            
        IPluginExecutionContext context = PluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));            
       if (context.OutputParameters != null)
       {
          Entity entity = (Entity)context.OutputParameters["BusinessEntity"];
          if (entity.Attributes.ContainsKey("new_markerexists") == false)
                return;
          entity["new_markerexists"] = "Marker exists.";

However, CRM plugin can not find this or any other custom field. It works fine with the standard fields.

What am I missing here?

Thanks!

what means "CRM plugin can not find this or any other custom field", do you mean that if you do entity["firstname"] = "TEST"; with firstname as standard field, your retrieve returns the updated value? — Guido Preite

As stated here: https://stackoverflow.com/a/9903306/1023562

In CRM, only properties that have been set or updated are included.

My custom fields did not have any value set, so CRM simply did not include them in entity.Attributes collection.
