[Freeswitch-users] Does chatplan support javascript?

Hi FS Gurus, I'm new to freeswitch. Trying to use javascript in chatplan, but get error code c:716 Invalid chat application interface [javascript]! Same fucntion call in Lua is OK. So looking chatplan not support javascript? If yes, any plan to add javascript to chatplan? Chatplan mainly dealing with text manipulation, Lua is a bit weak at string handling. /rgds, Pip
