Hello everyone!

I'm having yet another problem :(

Here's how it goes : 
I have a block, with a TileEntity and a GUI that is a vendor. It shows 9 items at once, which you can click to select and then buy.
The GUI is also open-able with an item, to benefit from remote access to the vendor.

Here's the problem :

When I open my GUI via the block :
wnIPBoC.png

When I open the GUI via the item : 
N4cYzem.png

However, in both cases, I can click on the slots to select the items, which means that the items ARE put in the slot in both GUIs, but they're not drawn on the item version.

I have tried disabling the render of the background image in case the items were, for some reason, behind the background, and they are not.

Here's the GUI code :

If any other code is needed, be sure to ask.

Please note that this problem is not specific to 1.11.2 since I also had it back in 1.7.10

Alright.

Container :
 

  Reveal hidden contents

GuiHandler :

  Reveal hidden contents

Item :

  Reveal hidden contents

Block :

  Reveal hidden contents

 

 

Some of the code is dirty, sorry

I don't need to save the content of the item's inventory (it is set when you open it), do I still need capabilities ? As far as I understand, those are meant to store data right ?

After converting to IItemHandler (only changing the Inventory class), I don't seem to get any changes from it.
I mostly do not understand why it works with the block, and not with the item.
