When I’m trying to run the tutorial code for injecting javascript, it doesn’t seem to be working. After some checking, I think the issue is, for some reason it doesn’t find the leaflet map object. The code runs though, but doesn’t do anything without the map. The default map is working, but I can’t do any customization due to this error. I have tried it in opera and chrome, same results. If I log ‘mymap’ variable to the console, this is the result:

Hi Papp,
May I know what are you trying to accomplish?
Note that we already have built UI driven map customization options which can be used for achieving a lot of things and it might happen that you might not need to use JScode all together

Hello,
I wanted to fill up the map with polygons from a geoJSON file, and I think I can’t do that with the customization features presented. Is there any way to fix the issue I’m having? Thank you in advance,
