I enabled feature to load map objects by ajax requests.
In map details on “Advanced options” tab now you can set “Load map objects dynamically” to JQuery (MooTools is supported too, but it was deprecated by joomla)
After that placemarks and paths will be loaded by ajax requests.
And now parameters “Load type”, “Buffer size for placemarks”, “Buffer size for paths” will be used.
PS: Today some features doesn’t work with ajax loading:
* paths – KML/GPX files
* visualization (placemarks, paths)
