ActionServerside() and player functions

[Yen]

Alright.
If I trigger onActionServerside() and call a player-function in the block, my params[] array will be overwritten by the player-function.

PHP Code:

//NPC Weapon
function onActionServerside() {
  echo("params[0] before call:" SPC params[0]);
  player.DoStuff("abc","123","doremi");
  echo("params[0] after call:" SPC params[0]);
}

//#CLIENTSIDE
function onPlayerChats() {
  triggerserver("gui",name,player.chat);
} 


The first echo will give me player.chat
The second echo will give me 'abc'

Shouldn't the params[] for the weapon be inside the weapon object?
