A Point / Line not drawn on map

[ShaningYu]

I have an JS application, which could add queried point / line on the map.  But now, the point / line queried does not display on the map.  It means it is not drawn.  What is the possible reason to cause the problem?  Thanks if you can share your experience.

If this is the result of a QueryTask then you need to handle adding the results to the map. Check out this sample - specifically how the addPointsToMap function is used to add the results to the map.

Problem found to be projection related.  Thanks to the reviewers.
