I experimented with some getters and setters of the data selection - but it did
not make a difference - does not work either way.
Also, it does not matter if I use the "addSpace" method to add new things - if
I just render objects already in the database I have the same problem.
The pagination code is there to support a view that is not converted to use a
datascrooller/paginator.
In this version of the select method I try to pass the selected thing as a
parameter from the facelet. My previous attempt did not use that - it produced
the same result.
Will now post the remaining parts.
