I’m trying to make a component view with OSM Map viewer or Palladian Map Viewer, but both doesn’t work as a part of the component view (while working perfect as nodes).
Is it OK and just a limitation of these exact nodes or something is wrong with my preferences?
components will only show JavaScript based visualizations and Widgets in their composite views. As these nodes are not JavaScript based visualizations they will not be shown in the composite view. However, you could use OSM Map to Image to create an image of that map visualization and then display that image in your composite view with Image Output Widget.
