how to use openstreet map

Hello @SD_11980450 ,
I am not sure what you are trying to do with OpenStreets, The Extension I provided, is my hack at getting it to work.
I have had some success, also some failures in a testing environment.  If you create a Mashup and just add the OpenStreetMap widget, I believe you will get a map centered on London.  
If you want to affect the information displayed you will need to create a data source. The data source can be a Service or property which is bound to the widget.  I took a quick look at ThingWorx 9.7.0 (closest version I have to your version) and It should display the initial map.
What data are you providing to the bindings?
If you can provide a Sample I will be happy to see if anything jumps out?

Regards,

Pehowe
