If the item hasn't been encountered since the game client was last started, this function will initially return nil, but will asynchronously query the server to obtain the missing data, triggering GET_ITEM_INFO_RECEIVED when the information is available.
Since you store the item already, you should store the actual link because it carries more data than the itemId (like forging, sockets and bonus effects)

To get some information about an item immediately, you can use GetItemInfoInstant
Lua Code:
  1. itemID, itemType, itemSubType, itemEquipLoc, icon, itemClassID, itemSubClassID = GetItemInfoInstant(itemID or "itemString" or "itemName" or "itemLink")

Though it is not documented, this function apparently returns info available directly in client files. Because of that it returns less data, but have several advantages over GetItemInfo: it always return data, when GetItemInfo can return nil for valid, but not loaded items and it never initiates requests to server, that could be subject to throttling or forced disconnection.
