I have a problem with detecting intersections between polygons. I have 2 sets of polygons and they have intersection between each other. For example we have 1 pair from 1 and 2 set that must intersects.
But programm says that only circle 1 intersects polygon 1 and polygon 2 and circle don't!
That is my workspace:
What is wrong with my settings and what should i do to detect every intersection?
I'm not sure but I think the SpatialFilter stops after finding the first match. If you try it with a SpatialRelator instead you'll get a list of all matching candidates.
Hi @markyandex, is there a geometry difference between the circles? how does FME 'see' the geometry of the 2 features?
Ok now it detects intersections but the next problem is attributes: for 1 requestor only 1 supplier, but the total amout of intersections is 2 for each Circle, what's wrong? I want to see comparison like Circle 1 intersects Polygon 1 and Polygon 2 and Circle 2 intersects Polygon 1 and Polygon 2, but now only Circle 1 intersects Polygon 1 and Circle 2 intersects Polygon 1.
You may want to test switching the Candidate and Filter inputs.

Sorry missclicked. Answer to you below.
the 1 to many relationship is reflected in the list generated by the spatial relator, see the help on the transformer for more information
Ok guys i reached my task. This helps me https://groups.google.com/forum/#!topic/fmetalk/c_SjMXlURng but it's strange that i dont have some tests to perform (for example overlap) in my spatialrelator, so i used downloaded workspace to solve my problem.
