I think you have that:
- your map has external placemark position, and it works, displays all placemarks etc.
- now you try to show map by plugin for definite placemark from that map, and get the error.
Yes. It is a little problem. I show map and all its attributes based on placemark link to map. And in your care - map has placemark list.
1 - in future release I fix that, I will disable placemark list if call by placemark id
2 - today you can fix it by trick: call plugin not by placemark, call by placemark list, and pass to it your placemark, and set centering by placemark. And for that case create simple map without placemark list
I am going to use another similar work around. I've created a map without the placemark list, just the pins on the map and then in the balloons for the placemarks I created links to separate subpages featuring each placemark location, which is something I am doing anyway.
Thanks for an amazing component, wish I had the brain power to use it at its fullest, it really is amazing.
