post your IGuiHander impl, as code not as download plz
in your IGuiHander impl you have a world and x y z you can get the tile from there and have your gui take a tile in its constructer
like so
public guiCommandBlock(TileEntityIronCommand tile)
and a field that holds the tile
what he means is hoppers can extract items out of Entity's using the IInventory but not Itemhander
as you can see in the spoiler getInventoryAtPosition first checks for tile and then for Entity's
it get also used in BlockDispenser line 54
