stateSave and stateDuration set to -1, nothing in session

Hello,

I would like to access the current state. I've set the bStateSave to true, and stateDuration to -1.

But when performing a search operation and dumping the $_SESSION, nothing about datatables is present.

But it does save the state somewhere, because after a page reload it remembers the search query. It doesn't refill the input though, that's why I'd like to access the current state.

Thank you,
