How to retrieve list with dissolver

Hi all,

 

I look for ideas to retrieve all values of my attribute if the dissolver count has more han 1.

 

Example :

 

I have 3 shp with ("Name" and "Code" attributes). I connect there with Dissolver transformer (with Dissolver Count Attribute = "NB_Layer" and Liste_Name = "list_layers").

 

I need to add a new attribute with attributeCreator ("LIST_CODE") that contains : 

 

list_layers{0}.Code IF  NB_Layer = 1;

 

list_layers{0}.Code "," list_layers{1}.Code IF  NB_Layer = 2; (concatenation of codes)

 

...;

 

list_layers{0}.Code "," ... "," list_layers{N}.Code IF  NB_Layer = N;

 

 

Thanks an advance.
