2 Seam 2.0.0CR2 JSF 1.2 3 I'm not entirely sure what I need to do regards Stateful / Stateless for this bean. Another slightly smaller issue is that it does not select the "no Selection" item as default. I would like this to be the case. Any ideas on that? I have created a somewhat working version by using the following.

I will look into this Stateful idea and see what affect that has. But I would REALLY like it if I could make the noSelectionLabel the default selection in the selectOneMenu View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4098640#4098640 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4098640 _______________________________________________ jboss-user mailing list [email protected] https://lists.jboss.org/mailman/listinfo/jboss-user
