Hm... maybe the problem is caused by something else. I found another exception some lines above in the log. java.lang.StringIndexOutOfBoundsException: String index out of range: -1 | at java.lang.String.substring(String.java:1768) | at org.jboss.seam.jsf.AbstractSeamPhaseListener.selectDataModelRow(AbstractSeamPhaseListener.java:86) I must say that I do not use a @DataModel, and so the dataModelSelection parameter in the URL after clicking a s:link is empty. (Yes, I do have a reason for not using @DataModel: When having an outdated list page, then clicking a link may result in a different entry to be displayed.) So, any experiences or ideas with this issue? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984558#...
