Yet another problem with natural conversations here ...
If the user finishes a conversation (by clicking on an seam link element), then clicks on the back button of the browser, re-clicks on the same seam link, the logs show an exception that says:
java.lang.IllegalStateException: conversation id evaluated to null: regmem at org.jboss.seam.navigation.NaturalConversationIdParameter. getParameterValue(NaturalConversationIdParameter.java:71) at org.jboss.seam.navigation.NaturalConversationIdParameter. getConversationId(NaturalConversationIdParameter.java:63) at org.jboss.seam.navigation.NaturalConversationIdParameter. getInitialConversationId (NaturalConversationIdParameter.java:45) at org.jboss.seam.faces.FacesManager. generateInitialConversationId(FacesManager.java:128)
At which point the debug page shows a whole bunch of information about what went wrong. How to simply redirect the user to a home page and not spew a bunch of debug information in a page?
