Hi Tony,
It's probably best to keep this on the myfaces mailing lists because
I'm not always around and, more importantly, I'm not always right :)
Actually, t:columns effectively is a dataTable with
layout=lineDirection. It's just a UIData subclass with a custom
renderer that outputs <td> tags instead of <tr> tags.
Any of the methods and attributes for dataTable work for columns. In
fact, you have to mentally-convert "column' to "row" when you use it,
because columns refers to its columns as rows. Ie,
Columns.getRowData() really means Columns.getColumnData()
It's unclear to me why you're using a facet rather than just add
columns to the t:columns children.
