Thanks for your faster answer SteveJG. No sorry dont have any marker on the Designer Marker Properties because I dont include any marker at design level. Im triying to create a batch of Markers at Run-time level. I think reading the documentation of the FeaturesFromGeoJSON block that this is the way for a dynamic creation of Markers at run-time. In the meantime I will try with the Create Marker block as you answer in this post:
Where are you supposed to plug in the featurefromdescription block?
Instead of assemble a GEOJson string need to create a list of 4-items-list and using the AnyMarker blocks to assign features, well another aproach.
But my initial assuption is wrong ? GeoJson can parse only Lat and Lon. ? not others features ?
Thanks for your time Steve,
