Okay, so I have been struggling with this for a very long time now and I really need to figure out a fix for this issue. So this is my problem, I have my plugin setup to dispatch command as the instance of the player correct? I tried using both player.performCommand and Bukkit.dispatchCommand both didn't work. If I have the player dispatch a normal command such as /help or /spawn as well as 90% of all other plugins commands such as navigation menus or ultra cosmetics, etc it works great and executes just fine! My problem is I have currently ran into 4 plugins that I cannot get the players to execute the commands for. 1.) ChestCommandsGUI (executing the commands for the custom menu's doesn't work). 2.) MyCommand (executing any custom command created within this plugin doesn't work). 3.) BuyCraft (executing the /buy command only). 4.) MinecraftMarket (executing /buy command only). I debugged it and the players are properly executing the command but for some reason it returned as unknown command! It shows the player typing the correct command though so I don't really understand. If you manually type in the command via the chat window it works fine but if my plugin attempts to make the player execute one of those commands from those plugins it doesn't work. Any incite into this would be great and I can clarify anything if needed to.
