Uncaught TypeError: Cannot read property 'spatialReference' of undefined

Question asked by michaelschnack on Dec 24, 2014

I'm creating a map that can be launched from a URL that contains a name, address and lat & lon.  When the maps launches I would like for it to automatically display an infoWindow containing the name & address at the coordinates that have been parsed from the URL. 

 

I'm taking the coordinates and creating a new Point, then converting that point to web mercator and using it as the center of the map.  But when I try to convert the web mercator point to a screen point to use in map.infoWindow.show, I get the error: Uncaught TypeError: Cannot read property 'spatialReference' of undefined. 

 

If I try to use the web mercator point in the show method the error is:  Uncaught TypeError: Cannot read property 'toScreen' of undefined.

 

Any suggestions would be appreciated, thanks.
