I have asked this before but no one has ever answered. I am trying to use s:convertEntity with a selectOneMenu but get an error that the convertEntity tag is not defined. I am using seam 1.2.1. I upgraded from seam 1.1.6. The project was created using seam generate-entities. I have spent much time trying to configure this to work. Can someone please tell me how to set up seam to be able to use the convertEntity tag. Also, although I followed directions on the jboss site I am not sure that I upgraded Seam properly. Any help would be greatly appreciated. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4069299#...
