Problems with custom Crafting Table

Hi!

 

I created a new crafting Table with new recipes which take Mana from the Player.

Everything works fine except from one fact:

If I perform a shift-klick to craft as much Items as possible, neither the Crafting result is placed in the Inventory of the player, nor the Mana is reduced by the specified amount. Only the Crafting-items are removed. Can anybody tell me, why?

 

The Slot for the Crafting result:

 

package magicum.minecraft.items.crafting;

    public ModSlotCrafting(Container owner, EntityPlayer par1EntityPlayer, IInventory par2IInventory, IInventory par3IInventory, int par4, int par5, int par6)

OK, I solved it now, but I really don't understand y´why:

I just put addPlayerInventory(inventoryPlayer); to the Top. Now it works..

Such a little problem  :-\

 

But now, I got another Problem:

 

If I do a shift klick, I craft as much Items as possible from the Item Count. But if I got maybe the Mana for 2 Items and the Items for 4, it will craft 4. How can I add a Control for the Mana when performing a Shiftklick?
