DataModel with <s:link> or <s:button> Error ------------------------------------------- Key: JBSEAM-1582 URL: http://jira.jboss.com/jira/browse/JBSEAM-1582 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 2.0.0.BETA1 Environment: All seam versions Reporter: Evan Zeng Assigned To: Norman Richards Fix For: 2.0.0.CR1 If a page references a property of the back bean, then using <s:link> or <s:button> action to delete the last row of data backed by a DataModel will cause an exception with the following root cause: java.lang.IllegalArgumentException javax.faces.model.ListDataModel.getRowData(ListDataModel.java:139) ...... This bug recurs when we make the following modifications to the 'messages' seam example : 1. Add a property 'title' to the MessageManager bean. 2. In messages.jsp, change the header 'Message List' to '<h:outputText value="#{messageManager.title}"/>'
