Can anyone explain the thinking behind seam el not throwing an exception if it comes across a unknow el expression? for example; <h:outputText value="#{listInvitedUsersInFolderService.firstItem + 1} ... #{listInvitedUsersInFolderService.itemCount < listInvitedUsersInFolderServicefirstItem + listInvitedUsersInFolderServicebatchSize ? listInvitedUsersInFolderServiceitemCount : listInvitedUsersInFolderServicefirstItem + listInvitedUsersInFolderServicebatchSize}"/> This output is not displayed, but the page is with no errors. I mistakenly omitted some full stops, it should be : <h:outputText value="#{listInvitedUsersInFolderService.firstItem + 1} ... #{listInvitedUsersInFolderService.itemCount < listInvitedUsersInFolderService.firstItem + listInvitedUsersInFolderService.batchSize ? listInvitedUsersInFolderService.itemCount : listInvitedUsersInFolderService.firstItem + listInvitedUsersInFolderService.batchSize}"/> To reiterate, why does the seam el processor not compain about the first expression? just out of interest you see.. thanks (using seam1.2.1, faclets, jboss 4.21) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4091407#...
