Attribute sortable in grid

[Cucchietti Denis]

Hello everybody !

I have a little problem in my grid component. I want to offer the possibility 
to sort a column in my grid. The problem is that this column is not an 
attribute of my object.

I have created a new attribute in my grid component like this :

TML :

<table t:id="structureRelationsGrid" t:empty="block:empty" 
pagerPosition="bottom" model="gridModel" t:type="grid" 
t:row="structureRelationRow" t:rowIndex="rowIndex" 
t:source="structureRelationsResult" t:rowsPerPage="${message:rowsPerPage}" 
t:inplace="true">
                    <t:parameter name="relationCell">
                        <t:textoutput t:value="relationLabel" />
                    </t:parameter>
</table>

JAVA :

BeanModel<Structure> model = 
this.beanModelSource.createDisplayModel(Structure.class, this.messages);
model.add("relation", null).sortable(true);


public String getRelationLabel() {
            if 
(this.listOfParentStructures.contains(this.structureRelationRow)) {
                  return "Belong to";
            }

            return "Combines";
}

So, I've the icon that indicate that the column can be sort but it's don't work 
! I would like can sort by "Belong to" or "Combines".

Have you any idea?

Thanks a lot !!!
