I have the same problem. I've been trying several different repeater and datatable components from both Tomahawk, Trinidad and Facelets with the same result. The standard h:commandLink works fine, but an identical s:link always send null as parameter value. Whats wrong? I m using Seam 1.1.6, Myfaces 1.1.4, Facelets 1.1.12, Ajax4JSF 1.0.6, Trinidad incubator-m1-SNAPSHOT View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4019371#...
