[Qgis-user] Rule Based Symbology with aggregate Function

[Jürg Lindauer]

Hi

I'm trying to create a rule based symbology with

"id_alpperimeter" IN (aggregate( layer:='alpperimeter20190607152251688', aggregate:='concatenate', expression:= "pk" , filter:=selected = '1', concatenator:=concat( char(39), char(44), char(39))))

But there are no results in there.

The rule based Symbology is ok, when i write the list directly:
"id_alpperimeter" IN ('258eef41-8120-45a5-a3d9-6ceae1e98e42', 'a882577f-eee2-4191-aa3b-2c4635bac70b')

The aggregate function alone gives me the expected list:
aggregate( layer:='alpperimeter20190607152251688', aggregate:='concatenate', expression:= "pk" , filter:=selected = '1', concatenator:=concat( char(39), char(44), char(39)))   Result: '258eef41-8120-45a5-a3d9-6ceae1e98e42', 'a882577f-eee2-4191-aa3b-2c4635bac70b'

What i'm doing wrong? Isn't possible to connect the 'IN' Operator with the aggreagte Function?

I'm using QGIS 3.4.11
