I have two set of polygons A and B.After passing by dissolver transformer,it doesn't dissolve all the polygons.Instead it only dssolves in a random fashion.This results in missing of the polygons in dissolved polygon shape.
Polygon A:
Polygon B:
After dissolving A,B.I get this output.Clearly it is missing few of the polygons in dissolved shape.
Also shown below - Highlighting the dissolved in dotted(with coordinates) and missing the other polys with no dots.
Used parameters:
Any thoughts please?

I'd strongly advise trying FME 2018.x (release or 2018.1 beta) with a Dissolver set to have Tolerance at Automatic.
Hi@fmeuser_gc,I remember that the Dissolver could not work as expected in some special cases,including the case where the target areas were ellipses or elliptical polygons overlapping each other.
I did change the Input Ordered to No and it's still same behavior.Infact this time,more polygons are disappeared now.
Regardless of this change,I do see the above observations in log window:
Here the 20811 input polygon number is right.However don't know the exact number of dissolved polygons.I found this difference when I visualized it.
A quick thought - change the Input Ordered to No.That might be causing the assumption that data arrives in an order that it doesn't.If that helps,let us know because I would want to check with development about it.
