[Sputnik-list] Error when creating a new empty lua node

[Jérôme Vuarand]

Hi list,

Whenever I create an node in Sputnik with the prototype @Lua_Config, I
get an error. A workaround is to create it without prototype, and then
change the prototype.

The error is caused by a loadstring call with a nil argument, I didn't
manage to find why the argument is nil (the stack contained several
tail calls and some anonymous closures), but below is a patch that
seems fix the problem on my website:

    local function do_lua(lua)
+      if type(lua)~='string' then return nil,"invalid lua code string" end

       local f,err = loadstring(lua)
       if f then

The do_lua function has another "return nil,'message'", so I did the
same. However my error message didn't show anywhere, maybe it's simply
ignored.

Tell me if there's a better solution.

Bye, Doub.
