So I pulled hes project from https://github.com/DavidGoldman/NBTEdit

To update hes mod for personal use. After several fix's and patches i succeeded to remove the errors in Eclipse

however when i want to edit a chest with items it crashes with this error

Caused by: java.lang.ClassCastException: org.apache.logging.log4j.core.Logger cannot be cast to java.util.List

The Section in question here is

 

    public static NBTBase getTagAt(NBTTagList tag, int index) {
        List<NBTBase> list = ReflectionHelper.getPrivateValue(NBTTagList.class, tag, 0);
        return list.get(index);
        
    }
}

I have also been looking into the other Class' which cast an error but nowhere do it look like its ever been a org.apache.logging.log4j.core.Logger type.

i have been trying to changing different things but all is casting the same error that Logger cant be cast into what i try.

 

The mod does however work if the chest is empty, but then crashes with the same error after i mannually add a TAGCompound. (like i would do it in 1.7)

 

 

But what would i use if not ReflectionHelper?

 

Also index is just the TagCount looped in a For event. so i can get every tag

perhaps that is the problem but how do i know which tag is the "logger"

and why wasn't this(the logger) present in 1.7.10? (as this code is confirmed to compile and work in 1.7.10)

Use ReflectionHelper.findField.

when using

Field field = ReflectionHelper.findField(NBTTagList.class, tag.getStringTagAt(index));

 

I get this error

java.lang.NoSuchFieldException: {id:"minecraft:chest",Damage:0s,Count:1b,Slot:13b,}

The "id:"minecraft:chest",Damage:0s,Count:1b,Slot:13b," is the part that i want to return as a List<NBTBase>.

so how would i go to first fix the error and second make it into the desired type?

 

Since i thought it might be caused cause the Tag.getStringtagAt

i thought perhaps i could get the entire "field" using

Field field = ReflectionHelper.findField(NBTTagList.class)

but this gets me

"Caused by: net.minecraftforge.fml.relauncher.ReflectionHelper$UnableToFindFieldException"

 

I dont think i understand the findField, and when i looked up how it was coded it reminded a bit of getPrivateValue so i dont really know how it would be "better."

Oh doh yeah hehe.

I see what i did wrong there xP

 

I got it to work now =D

 

Thank you all!

Hey, i know this post is a few months old but could you upload the jar? as i want to work on a map and i need the mod
