Error with ReActions

[OscarGLorenz]

Hello,

I have an error when using /vsign function. I am able to write the name of friend in the sign, but when I close it I am kicked from the server and I get this error:

ProtocolLib is a plugin that is necessary for lots of plugins and a must have plugin in a server.

I'm using ProtocolLib 3.6.4 and "CraftBukkit version git-Spigot-0359393-9cd1111 (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT)"

What's the command you are trying to execute with /vsign ?

[OscarGLorenz]

All commands, including your /resgui add friend, etc...

[FastFelix771]

I'll test the plugin with ProtocolLib, the technique behind the /vsign is a bit dirty :/

[FastFelix771]

I have tried it with the newest versions of Spigot, Towny Advanced, TownyWands and ProtocolLib. It worked perfect! Do you have any other plugin that uses Signs and ProtocolLib? The error you posted above tells something about Chat Packets, what is your ChatPlugin?

[OscarGLorenz]

My fault, I tested again adding to my server plugin by plugin and the guilty plugin is ReActions 0.9.9 : http://dev.bukkit.org/bukkit-plugins/reactions/

[FastFelix771]

Does it react to Signs? I will try to find a way arround this issue, its time for an update anyways ._.

[OscarGLorenz]

Yes it does One of the features of reactions is recognize predefined words in signs to Activate some "ReActions" on click

[FastFelix771]

I have updated and tested the plugin a little bit, hopefully it contains the fix you need. In my tests it worked well with ProtocolLib, Towny, TownyChat, ReActions and some Economy plugin on Spigot 1.8.8 (tested with PaperSpigot, too)
