I am quering a FC for a specific field value
Returning the Feature and displaying it in a Graphic.
This works fine.
I am then attempting to do the same by calling another function to
Use the Geometry of the Graphic to select all the COunty Features that Intersect it...
THis part if failing and I cant see why.

Both FC are Web Mercator Aux Sphere

The Map is defined as follows ---- I think this defaults to Web Mercator Web Aux?

QUESTIONS:

Am I getting this error because I am trying to use a Graphic Layer from the First Function Above?????

Can I use graphic Layer? If so do I need to define it differently?

Do I need to use a Feature Layer?

I got it with this: i was missing the "items"

query.geometry = resultsLayer2.graphics.items[0].geometry;

NOT

query.geometry = resultsLayer2.graphics[0].geometry;

I had to walk the console.log of the Graphics layer a bit more

query.geometry = resultsLayer2.graphics[0].geometry;

jaykapalczynski

query.geometry = resultsLayer2.geometry[0]; ????

rscheitlin

Jay,

The queries geometry property has to be a single geometry. You are currently attempting to pass a GraphicsLayer with possibly multiple graphics.

jaykapalczynski

Funny thing is I get this error but the 2nd function still displays data but for some reason ALL of the County data....not the ones that are intersecting the Graphic Layer. So I am assuming I might have to define the Geometry of the Graphic Layer?
