Paul, I want to say dataTable renders all rows based on the value attribute.
Then again, I want to say, somewhere I added the rendered={ } logic and the
"row" didn't display(i.e. I didn't have a blank row).
If I remember correctly, I didn't have a <f:facet name="header"> tag and I
was only displaying a few columns inside a commandLink which took me to a
details page. It's been a while...
I echo the collection level filter - but you already know that from your
original post.
