Maps widget on web page, refresh on filtered list with coordinates

Hi All, I have a maps object (OpenStreet) on a webpage. I load the markers with a nanoflow which works on initial load.  I have added a filter and filter the list with markers on a click of a button. I call the same source nanoflow and return the filtered list. I was expecting the markers (or even the whole map)  to redraw showing only the filtered markers but nothin happens. Any suggestions how to redraw the map or markers based on the filtered list? Thanks   Willem Jan

Two things come to mind that may be a bit obvious but still good to check:
1: are you sure you refresh your page so that the new data is also shown?
2: is your Maps widget based on the context object you are refreshing?
