I'm trying to store a String NBT tag in an NBT List, however I'm getting a "Adding mismatching tag types to tag list" when adding it to the list even though the current tag type of the list is 0 (so it should accept it and set its type to String)

 

The code doing it is:

NBTTagList chunkList = ticket.getModData().getTagList("Chunks", Constants.NBT.TAG_STRING);
NBTTagString string = new NBTTagString(chunk.xPosition + "," + chunk.zPosition);
System.out.println("Type: " + chunkList.func_150303_d());
list.appendTag(string);
System.out.println("Type: " + chunkList.func_150303_d());
ticket.getModData().setTag("Chunks", chunkList);

 

And the output is

Type: 0
WARNING: Adding mismatching tag types to tag list
Type: 0

 

And for the record, the println's are temporary, I would use the Logger otherwise

Read what getTagList does (source).

 

key = "Chunks" is most likely NOT a list which results in returning new NBTTagList of type 0.

Shouldn't it still let me add a value to the new list it returns though?

Actually it should.

 

Could you maybe try it on fresh list? Literally "new" keyword.

Maybe try using number instead of static const? (you want 8 i think).

 

Investigating it now...

...nevermind

I made a stupid mistake, I was working with two lists in the method and I was adding it to the one named "list" instead of "chunkList"

Thanks for the help though
