NPC shop issue

[christiandb]

I'm trying to make a npc called Gorn sell vials of oil. Here's the code of the npc:

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Gorn" script="data/npc/scripts/default.lua" walkinterval="1000" floorchange="0">
    <health now="100" max="100"/>
    <look type="129" head="58" body="68" legs="101" feet="95" addons="0"/>
    <parameters>
        <parameter key="message_greet" value="Oh, please come in, |PLAYERNAME|. What sort of {goods} do you need?"/>
        <parameter key="message_farewell" value="Good bye, |PLAYERNAME|."/>
        <parameter key="module_keywords" value="1" />
        <parameter key="keywords" value="goods;job;" />
        <parameter key="keyword_reply1" value="My inventory of general goods and paperware is large, ask me for a {trade} to take a look." />
        <parameter key="keyword_reply2" value="I am selling equipment of all kinds. Do you need anything?" />

        <parameter key="module_shop" value="1"/>
        <parameter key="shop_buyable" value="vial,2006,20,11;rust remover,9930,100;book,1971,15;book,1972,15;book,1973,15;bottle,2007,3;bucket,2005,4;backpack,1988,20;bag,1987,5;cup,2013,2;document,1968,12;fishing rod,2580,150;jug,2014,10;machete,2420,40;mug,2012,4;parchment,1969,8;pick,2553,50;plate,2035,6;present,1990,10;rope,2120,50;scroll,1949,5;scythe,2550,50;shovel,2554,50;torch,2050,2;valentine's card,6538,30;watch,6091,20;worm,3976,1;Obsidian knife,5908,1;blessed wooden stake,5942,1" />
        <parameter key="shop_sellable" value="" />
    </parameters>
</npc>

The vial does appear in the trade channel but when I try to buy it I get the following console error:

[ShopModule.onBuy] Item not found on ShopItems list

Is there any way to fix this?

It's because of reverseFluidMap, try looking at the vial sprite in the trade window.
It's possible to fix with some ugly hacks in NpcSystem and/or source.

The picture in the trade window really shows a vial of oil. Could you provide me those "hacks"? I have that error at so many items, it's getting annoying.

 

[Cykotitan]

When you look at it, it says 'You see a vial of oil.' ? wtf

I have to try, I've never seen this error :S

EDIT
The only error that I have it is that the vial is of beer - not oil.

Here you have a screenshot.

And when You buy it console shows error?

What TFS do you use?

 

[christiandb]

0.4_dev and the console shows the error mentioned in the mainpost.
