I have a strange behavior with one of my panel where i have a clustered map. Pratically i have two imput panel, one that permit the selection of a country, and the second one who permit the selection of a city. Depending on the city select i have two tokens that saves the respecting lat and lgt of the city, and then in the xml source i give this two toker for centering the map.
Pratically the result is blank, but if during editing before saving i go the source tab then the visualization works. But then if i refresh the page the map doesn't appear anymore.
