Hi There,
I am new ini FME. I have the latest version.
I used the DISSOLVER transformer to dissolve the polygon and the generate list functionality to get the list of all the blocks have been dissolved by the group field. The result is I can see the POLYGONS dissolved but I don't think I am generating any list of these polygons. Also how to get the count of how many polygons have been dissolved by the group field?
Thanks for your help

Hi @manuciao To see the list that gets created for every dissolved polygon, insert an Inspector or Logger after the Dissolver. Use a ListElementCounter if you just want a count of how many polygons were dissolved together.
+18Using the Dissolver settings (see image) you can create a list of the name attributes.
Then using the ListConcatenator transformer, you can concatenate those names into one attribute on the dissolved polygon.

Thanks @DanAtSafe and @erik_jan I managed to use the generate list option in the dissolver adding the ListConcatenator to get my list of polygons separated by comma.
