ListModel iteration

[Kaluss]

Hello all,
got some confusing beginer problem with ListModel iteration.
When I try to acces property Im reciving undefined message.

@
function unsetOthers(frame){
frame.FrameID;//<----this works fine
for(var i = 0;i< boardModel.count;++i){
console.log(boardModel.get(i).frameID)///<---- in console I have undefined text
}
}
@

What Im doing wrong?
