title: Tridion 2011 with DD4T - no MetaData fields available on Component entity
body: <p>I'm using Tridion 2011 (with DD4T, feeding an MVC webapp). </p>
  
  <p>It seems that MetaData fields for Multimedia Components (specified on the Metadata tab of my Images Schema in Tridion) are not populating the corresponding property on the DD4T "Component" object. e.g. <code>LinkedComponentFields[0].MetadataFields</code> is empty and <code>Multimedia.AltText</code> is null. </p>
  
  <p>Specifically the field I'm after is the AltText. But as the entire MetadataFields collection is empty on the Component, it's obviously not pulling through any metadata properties. i have tried using TemplateBuilder to set parameters in the Component Template (I set "resolve width and height" to yes, and the MergeAction to Merge) - this did not help. </p>
  
  <p>Any ideas?</p>
