      The bug

      When I use an anvil (repair & name) on "Book and Quill" after naming I can't write something in this book. I can sign it but it stay are not writed.

      How to reproduce

      1. Get a new blank book and quill.
      2. Rename it.
      3. Try to type in it, it won't work.

      Code analysis

      Based on 1.11 decompiled using MCP 9.35 rc1

      The constructor net.minecraft.client.gui.GuiScreenBook.GuiScreenBook(EntityPlayer, ItemStack, boolean) tests if the book has the tag tag and if this is the case tries to use its pages value. Because this tag does not exist an empty list is returned. The problem is that the test for bookTotalPages < 1 (= empty list) only sets the bookTotalPages attribute value to 1, but does not add an empty string to the pages. Because of this the player is unable to write something.

      Suggested fix (1.11)
      public GuiScreenBook(EntityPlayer player, ItemStack book, boolean isUnsigned)
          this.editingPlayer = player;
          this.bookObj = book;
          this.bookIsUnsigned = isUnsigned;
          if (book.hasTagCompound())
              NBTTagCompound nbttagcompound = book.getTagCompound();
              this.bookPages = nbttagcompound.getTagList("pages", 8).copy();
              this.bookTotalPages = this.bookPages.tagCount();
              if (this.bookTotalPages < 1)
                  // Added the following line
                  this.bookPages.appendTag(new NBTTagString(""));
                  this.bookTotalPages = 1;
          if (this.bookPages == null && isUnsigned)
              this.bookPages = new NBTTagList();
              this.bookPages.appendTag(new NBTTagString(""));
              this.bookTotalPages = 1;
