Yes more than one geometry. Yes I'm using GeometryService.

Geometry type is polygon which I'm trying to get it unioned but it is throwing an error.

Intersect feature can be point line or polygon.

Akshay,

So your query results, do you have more than one geometry?
What is the geometry type?
The layer that you want to intersect with what geometry type is it?
You understand that you will have to union all the geometries of the layer into one geometry using the Geometry service right?
Which geometries will be the input and which will be the intersect feature?

Robert,

I'm querying on one feature class and getting its geometries and passing that geometry to intersect with other layer.

Can you please share code snippet to pass array of geometries.

Akshay,

The intersect ability that the Flex API has is designed for a array of geometries and a SINGLE geometry. So intersecting two feature classes is a little difficult.

Here is the Flex API docs on the GeometryService: intersect() method:
