You can't use convertEntity in this situation (it assumes that all objects in the list are entities, as would any converter). You can extend org.jboss.seam.ui.EntityConverter: @Name("myConverter") | @Converter | public void MyConverter extends EntityConverter { | | public String getAsString(...) { | if ("separator".equals(value) { | // it's not an entity, you deal with it here | } else { | return super.getAsString(...); | } | } | | // similar for getAsObject | } | | | | then you use it | | | | <f:converter id="myConverter" /> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044438#...
