@ebygomm Hello How are you
is not given the expected result still we have the same group id for them
The list combiner works as expected for me on that sample data
Creates 3 groups (I've coloured them based on the group attribute). Group 0 contains 1 feature, Group 1 contains 21 features and Group 2 contains 30 features

Hmm, you could use a dissolver to create two polygons out of the groups and then use a SpatialRelator/Clipper/SpatialFilter to pass a common arrtibute from the big polygons to the smaller ones. There's probably a better way but that would work

You can also use a reverse of @virtualcitymatt 's solution.
SpatialRelator/SpatialFilter to get the common attribute of the polygon and Dissolver with GroupBy on that attribute.

the features as connected to each one in Cascade A related to B , B related to C, ....
when you do the relator how could we get the common Attribute that related them all together?

If you use a spatialrelator to build a list of relationships for each feature, you can then use the custom transformer ListCombiner to assign groups

Have you verified that pano_name is unique?
In the ListCombiner I think you should also have pano_name selected under additional source attributes but I don't think that is the problem here
Are you able to share the data?
