finally got the dynamic column dataTable working with our view user role stored proc based on an example I found today using JSF + managed bean. I am currently porting it to a Seam version. This solution uses only one JSF tag (not two like the ICEFaces solution, one for dataTable and one for columns). The difference is the dataTable is programmatically manipulated in the managed bean (or SFSB/SLSB in the case of Seam) using Faces component classes. http://balusc.blogspot.com/2006/06/using-datatables.html see the section: Dynamically populate datatable View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4089421#...
