Hi. I have a problem, i have configured itemjoin like this:
(Here only important setting)
world (worldname):
Item: COMPASS
commands:

• 'player: menu' (menu to open chest command menu)
  But when i click with compass bukkit say "command not found"
  How can i fix it? I need itemjoin because i fan set item per world

Chest commands is very compatible with ItemJoin, thats why it's on the front page.

You cannot use custom commands because chest commands is some-what buggy.

Use
cc open menu
As the command.

You can only use the commands shown on the chest commands page

Sorry for the crappy response I was not home and at work but I wanted to give to a quick response, here is a more proper response;

I see this a lot, I wish I could tell you this is an easy bug fix on our end but its not. This is a bug with ChestCommands.

The best way I can explain it is the custom commands that are registered from his plugin are not real. They are ghost commands that are registered after ALL of your plugins are done loading. Therefor we cannot grab the command or communicate with it in any way.

The easy solution though is to use ChestCommands RAW commands.
You would want to use /cc open [file]
file would be the what the custom menu is saved as.
So it would be like this;
commands:
-'player: cc open menu'

or

commands:
-'cc open menu'

These are all the raw commands supported by all us developers
https://dev.bukkit.org/bukkit-plugins/chest-commands/pages/tutorial/commands-and-permissions/

As long as its not a custom command you created within ChestCommands, it will work.
If this has or has not resolved your problems please let me know.

Sorry for my reply now..
I have a new problem, my items.yml http://pastebin.com/iWJh3Hrw
I have a little server without bungeecord but with multiverse-core and when i change world (with "mvtp world_name") my items remain the same of MainLobby. I don't have multiinv, multiverse-intentory or other plugin. Please help me to set my items.yml with custom item per world, thanks

Edit: Solved. Maybe

Edit 2: new Items.yml now nether_star and slime_ball remains after changing world

The items are not meant to magically dissapear when switching worlds, you have to set clear-on-world-changed to true in the items.yml

Ops.. thanks

It's all good, if you are looking to only remove ItemJoin items this will be available in v3.7. Currently you can only remove all Inventory items.

3.7? but here i can see only the version 3.6

this will be available in v3.7, as you can see its not released yet I am currently developing it. There is no ETA atm but it should be out within a few days if everything goes smoothly.

Oh thanks
I wait for the new versione

ItemJoin v3.7 has been released and you can get it here;
