Hi Thiago.
First of all thanks for your response.
I have tried with a property conduit but the problem is my new column is not an
attribute of my object Structure so I don't know how to use it :
PropertyConduit propCdtAttribute =
this.propertyConduitSource.create(String.class, "relation");
model.add("relation",propCdtAttribute).sortable(true);
This solution doesn't work because the attribute "relation" doesn't exists in
String.class
I have also tried with PropertyConduit propCdtAttribute =
this.propertyConduitSource.create(String.class, "relation"); without success.
Cheers

You'll need to create a PropertyConduit and then use it in the model:
model.add("relation", yourPropertyConduit). In this case, you can have an
empty set() method, as you're not using this inside a BeanEditor ou
BeanEditform. This way, Grid will know how to get the values of that
column and sort them.
