Loading map with AJAX?

Hi, I don’t know if someone here knows or if it’s even possible.

I’m trying to load a map with AJAX but I get this error: “MapPress: Missing map name or container for map: null”.
Is there a script that doesn’t get fired or what’s causing this? Has anyone tried loading with AJAX? Could anyone point me in the right direction for solving this?

All help is much appreciated! And thanks for a great plugin!
