Hello, I have a situation where I am not sure how to debug it. Please help. I have an entry form where entry fields are mapped to a bean as followed: entry.xhtml <h:inputText id="teTradeId" value="#{tradeEntry.exchTradeId}" required="true" > | ... | <a4j:commandButton value="Add" action="#{tradeMgr.addTradeEntry}" reRender="tradeReportingPanel" /> | ... entry bean: @Name("tradeEntry") | @Scope(ScopeType.SESSION) | public class TdTradeEntry implements Serializable { | private String exchTradeId; | | @NotNull | public String getExchTradeId() ... | | public void setExchTradeId(String exchTradeId) ... | backing bean: @Stateful | @Scope(ScopeType.SESSION) | @Name("tradeMgr") | public class TradeManagerBean implements TradeManager, Serializable { | ... | @In @Out | private TdTradeEntry tradeEntry; | | public void addTradeEntry() { | // tradeEntry is always null in here | x = tradeEntry.getExchTradeId(); | ... | public TdTradeEntry getTradeEntry()... | | public void setTradeEntry(TdTradeEntry tradeEntry)... | | } For whatever reason, the injection of tradeEntry is always null which Seam would throw exception as anonymous wrote : Caused by: javax.ejb.EJBTransactionRolledbackException: org.jboss.seam.RequiredException: In attribute requires non-null value: tradeMgr.tradeEntry | If I was to declare the injection for tradeEntry with qualifier as (create=true) such as @In(create=true) @Out private TdTradeEntry tradeEntry; When I did this, all the fields in tradeEntry would be null. Am I doing something wrong with this model? Thanks for your help. -tony View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4046390#...
