Youre trying to set something at index 52 in an ArrayList, but the size is only 45.

 

@FisheyLP
No, -->I<-- am not, did you read my post or the stacktrace, the stacktrace does not show my classes anywere (all of my packages start with com.gmail.neonblue858). It has something to do with bukkit/spigot internally.

 

Errors are there for a reason. It doesn't show a class because it shows the java's error.

 

@ChipDev
I know errors are there for a reason! But the error shown does not indicate that it is my code that is at fault.

@timtower @ChipDev @FisheyLP @CodePlaysMinecraft
So i decompiled my server and found were the error is occuring

The line the error is occuring on:

Code:

//Line 140 in the above method
//Edit i meant line 140...
Slot slot2 = (Slot)this.c.get(i);

EDIT by Timtower: merged posts

 

@timtower
I am pretty sure the error is in the InputGUI class:

Code (open) Code (close)

Because the error seems to be caused by the size of the inventory firing wrong, however in the above code I am creating an inventory the size of a double chest under the type keyboard. However, I suppose what I should be mentioning is that my code fully works as intended the inventory opens properly, etc. HOWEVER something internally in bukkit does not accept my inventory...

 

bump?
