I got rid of all my code that used @datamodelselection in favor of using the parameter seam 1.1 supports. Now I use: <h:dataTable var="i" value="#{datalist}"> | <h:column> | <h:commandButton action="#{dataManager.selectItem(i)}" value="select #{i.name}"/> | </h:column | </h:dataTable> This works really well, especially if you have nested tables, you can pass the current table row selection into the function as multiple parameters using: <h:dataTable var="i" value="#{datalist}"> | <h:column> | <h:dataTable var="j" value="#{i.subdatalist}"> | <h:column> | <h:commandButton action="#{dataManager.select | SubItem(i,j)}" value="select #{j.name}"/> | </h:column | </h:dataTable> | </h:column | </h:dataTable> Of course this requires you to use Facelets and seam 1.1 with the seam FaceletViewHandler, but it REALLY simplifies things alot.
