[jboss-user] [JBoss Seam] - Re: Need help updating multi-table dataTable - injecting lis

ok, cool.  The updates worked for 3 different rows (6 cells total modified in JSF).  I verified with t-sql select to check updates were successfull.

only thing is I am seeing the following error(s) after submit:

14:19:23,918 INFO  [CustomerAction] in getCustomers(): user.getUserId() = 4461
  | 14:19:24,918 INFO  [CustomerAction] in destroy()
  | 14:19:38,573 INFO  [CustomerAction] in getCustomers(): user.getUserId() = 4461
  | 14:19:38,620 INFO  [CustomerAction] in submit()
  | 14:19:50,588 INFO  [CustomerAction] in submit()
  | 14:20:13,056 ERROR [SeamPhaseListener] uncaught exception
  | java.lang.NullPointerException
  | 	at org.jboss.seam.jsf.AbstractSeamPhaseListener.afterPhase(AbstractSeamPhaseListener.java:157)

I will try to determine if your way of doing is better or not.  this is the submit() code:

Iterator it = myList.iterator();
  | 
  |     	while (it.hasNext()) {
  |     	    Object[] result = (Object[])it.next();
  |     	    Customers customers = (Customers)result[0];
  |     	    em.merge(customers);
  |     	    CreditCard creditCard = (CreditCard)result[1];
  |     	    em.merge(creditCard);
  |     	}

Is it possible to do it all in one transaction??  Isn't the above doing two merges(updates) per row??
