Brilliant, I only had a short time to look at the Trinidad component
examples this week.
Thanks for the code in your earlier emial, I will down load the latest
SNAPSHOT and have a play with some code of my own. It is a shame that
this functionality was not placed in the orginal table. I guess you
have to draw the line some where.
I have been reading round the myfaces website and have seen the other
projects such as tomahawk and trinidad, but I was also wondering if
there were other repos of components out there? I have seen seam and
icefaces but I guess these are really frameworks that integrate with
other project such as jsf, tomahawka nd trinidad?

one more on that.
The rows="10" ensures that you only see 10 items on a page. IF you have more,
paging is done for you, without any other scroller or so. :)
