Issue With Villager Trade

I've been trying to make use of Villager trading to make some fort of banking/barter plugin, but have ran into an odd issue. I can get the trade to display fine(and set trades), but after completing the trade, the item that the user receives is a "ghost item" and will disappear when right clicked. I've done some debugging, and the click in the trading window is never registered in InventoryClickEvent, until you close the window(very odd).
Not 100% my code, but this is the method that I'm using:

If anyone has a solution, help would be greatly appreciated.

 

By not 100%, how much is your code?

 

Building the Packet250 was not mine, but I've looked into the protocol, and everything seems to be fine.

 

Looks like the code just fakes an inventory window to the player's client; it looks a bit outdated, there's probably a better way :/

 

I was hoping that there was an Api call somewhere, but I can't find anything. Oh well.

 

MerchantInventory
createInventory
openInventory
setItem

 

I guess I was going about the wrong way of doing things. Thanks for the links.

Got it working. I just spawned a Villager, set the trade, started the trade, and removed it.

Great

 

Try using my api for trades, no problem so far I know.
