not sure what activate does, I would hope though that it would add the object
to a panel on the page, and then you call "target.addComponent(<panel>);" As
this target (the AjaxRequestTarget) deals with actually updating the front
end of the page.
Also Data Repeaters are somewhat dubious in that they refresh their content
on each reload, so don't try to add the content to the DataView itself
(which I assume you are not). Similarly using the model and not the value of
the model might cause some issues, I am not sure. The stack error trace
after this first visual issue is fixed would be useful.
I do presume they are somewhat separate (ie: fixing one won't solve the
other).
