  == How to disable sorting for a column ==
  It is very likely possible to disable sorting for a column. How is that done?
+ One solution is to create a specific BeanModel for your Grid :
+ 
+  * Template part :
+ {{{
+ <t:grid t:source="list" model="model"/>
+ }}}
+ 
+  * Java part :
+ 
+ {{{
+     /** The model. */
+     @Retain
+     private BeanModel model;
+ 
+     /** The bean model source. */
+     @Inject
+     private BeanModelSource beanModelSource;
+ 
+     /** The resources. */
+     @Inject
+     private ComponentResources resources;
+ 
+     /**
+      * Page loaded.
+      */
+     void pageLoaded() {
+       BeanModel model = beanModelSource.create(Entity.class, false, resources);
+       model.get("XXX").sortable(false);
+     }
+ 
+ }}}
  
  == How to define the initial sort column ==
- ???
  
+ TODO not tested
+ 
+  * Template part :
+ 
+ {{{
+ <t:grid t:source="list" t:id="theGrid"/>
+ }}}
+ 
+  * Java part :
+ 
+ {{{
+     /** The form. */
+     @Component
+     private Grid theGrid;
+ 
+     @SetupRender
+     public void setupGrid() {
+         theGrid.updateSort("XXX");
+     }
+ 
+ }}}
+
