Hi Geoffrey, Indeed i have a viewport with a left panel and a map panel (in center region). My left panel is a tabpanel which has a treepanel and legend panel. The thing is even if i don't collapse the left panel i get this error just by doing a zoom in the map. Even when changing the layout i get the same error. At the moment i have no idea where to start to debug this... How did you solved it? Any more suggestions?
