When playing I noticed that I can't shift-click any items from JEI that have an empty slot in the crafting recipe. Only RFTools items weren't working.

Forge .2094
McJtyLib: 1.10-2.1.3
RFTools: 1.10-5.24

Hmm @mezz, any idea what could cause this?

What crafting station are you using btw?

This happens on EnderIO Inventory Panel, vanilla crafting bench and TiC workbench

I just tested this with only JEI, RFTools, RFTools Control, RFTools Dim, McJtyLib using a vanilla crafting table. Still happens

What version of JEI are you using?

3.11.2.278

I tested this with JEI .276 and it worked, but .277 -> not working

ok that's an important clue. Might be a bug in JEI instead of RFTools then

weird thing is that with other mods it works fine. Only one not working is RFTools

Yes, but this crafting recipe copying is not something that rftools is doing. Taht's fully JEI code

Thanks!

This is almost certainly a JEI issue, I'll take a look.

The key thing that changed is the way JEI handles null ingredients.
RFTools' Machine Frame has a null ingredient in the center.
Before, null ingredients were removed from IGuiIngredient rotations. Now they are kept, so people can have null in the list of ingredients for a slot.

The recipe transfer handler did not take this into account, I'll fix it shortly.

Fixed in JEI 3.11.2.280.
I made it so that any "IGuiIngredient list of ingredients that is all null" is simply collapsed into an empty list. This is easier to handle, because it looks the same as it was before to JEI and addons with recipe transfer handlers.
