[jboss-user] [JBoss Seam] - Can action called from button avoid committing transaction?

[tynor]

Seam 1.2.1-GA, JBoss AS 4.2.1, Hibernate 3.2.5ga

I wish to put a button on a form that adds an item to a list being displayed/edited in a dataTable.  The new item is not completely initialized -- until the user types in some values in the table columns, it's not ready for persisting.

On my MyHome class, I have a function

  | public void addItem() {
  |      getInstance().myList().add(new SomeEntity());
  | }
  | 

The problem is that after calling addItem, something is deciding to commit the new SomeEntity to the database. I don't want it to try to persist until I explicitly call em.persist() or em.update().  How can I stop it from persisting the object?

I've tried several types of button markup: 


  | <s:button action="#{myHome.addItem}" ...
  | <h:command action="#{myHome.addItem}" ...
  | <h:commandButton immediate="true"action="#{myHome.addItem}" ...
  | 

... and no matter what I do, hibernate is deciding to commit a transaction when I call through the button.  Help!

The stack in case that helps:
