I am trying to use the build-in geometry service to do a spatial relation with two graphics.The situation is like this:
I have temporary point graphics on a graphics layer. I want to draw another polygon to select some of those point graphics. Because the point graphics and the polygon I drew are on a graphics layer and not a layer from a map service, I decided to (or have to) use the GeometryService's Relation method do accomplish this task.
The three key parameters for RELATION method: geometries1 is set to the geometry array of the point graphics, geometries2 is set to the geometry of the polygon, and the spatialRelationship has no any trick.
But, I always got the error msg stating that: Unable to complete Relation operation.
The fault detail is: The specified geometry is not in the correct format.
I am basically following the ESRI sample: Determine Spatial Relationships. I have found one thing different between my case and the sample: in the sample, the geometry of parameter of geometries2 has extent. But in my case, for the same parameter, for the polygon I drew, the geometry has no extent (or extent is valued as NULL).
I am not seeing where you need to (or can at all) use a geometry service for this. When you get your polygon geometry then you just use polygon.contains (see documentation here):

Thanks for the response and the other way to work around.
I will try on it, and will let you know whether it works or not.
