Views: Iid seem to be wrong or often null - probably wrong relation

When trying to show pictures, the iid`s in views are often null ( in the render method ). I think its somehow related to how the join is done.

It sould look like this:
- Join using vid (from the current node), using the wysiwyg_imageupload_entity_revision table ( node.vid = wysiwyg_imageupload_entity_revision.vid)
- take all iid`s from this join, and join them with wysiwyg_imageupload_entity table(wysiwyg_imageupload_entity_revision.iid = wysiwyg_imageupload_entity.iid)
- take all fid`s from this join, and join them with files table (files.iid = wysiwyg_imageupload_entity.fid)
