I have added the below to pages.xml for the page containing the dataTable: <param name="entityId" value="#{mySelectedEntity.id}" /> But how would I modify the code from the previous post to take advantage of the injected request parameter? @DataModelSelection | @Out(required=false) | private MyEntity mySelectedEntity; | | ... | | public void removeMyEntity() { | // How does the remove know to take out the correct entity | em.remove(mySelectedEntity); | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4004982#...
