gs2 debug error?

[ZeroTrack]

just testing what would happen i made this:

PHP Code:

function onActionserverside(acc,weapon){
  e = findplayer(acc);
  if(e != NULL) echo("Found Player: " @ e);
    else echo("Player NOT found:" @ acc);
  e.addweapon(weapon);

}

//#CLIENTSIDE
function onPlayerchats(){
 tokens = player.chat.tokenize();
   if(tokens[0] == "/findplayer"){
     triggeraction(0,0,"serverside","Sern",tokens[1],tokens[2]);
  }
} 


and when weapon = NULL it returns a function error to the RC.

yes i could just add if(weapon != NULL) but i wanted to see if gs2 would look for the function addweapon if no weapon was specified. this also happens to removeweapon

this also happens if the weapon doesn't exist
GraalScript: Function addweapon not found at line 5 in script of Sern (in level test.nw at pos (0, 0))
