Thanks for the fast reply... I tried it out, but I got a
NullPointerException:

which eventually filters up to give:

org.apache.tapestry.ioc.internal.util.TapestryException
locationclasspath:org/apache/tapestry/corelib/components/GridColumns.html,
line 3, column 106
I entered the code you gave me into the Start java file and entered:
<t:comp type="Grid" source="prop:items" model="prop:modelForGrid"/>
in Start.html.
Start.java also contains:
private Collection<MyInterface> _items = _myService.getAll();
along with getters and setters.
MyInterface essentially is:
public interface MyInterface {
public String getDescription();
public void setDescription(String description);
public Date getLastModified();
public void setLastModified(Date lastModified);
public String getTitle();
public void setTitle(String title);
public Collection getCategories();
public void setCategories(Collection categories);
public Collection getReferences();
public void setReferences(Collection references);
}
I'm also interested in how Grid will handle collections/how I can tell it
to.
What am I doing wrong? :-( Thanks!

return _modelSource.create(MyInterface.class, false, _resources);

... and bind the Grid's model parameter to the modelForGrid property.
