Does the Seam download have a web app example that updates more than one table per form submission?
The hotel booking app, for example, updates the Booking table via the Booking entity bean whose values are set in the book.xhtml JSF.
Need to see a more complicated update. For example, what if the customer has more than one credit card and there is a CreditCard table that needs to be updated in addition to the Booking table? There will then be a 1:m relationship b/n Customer and CreditCard entities.
How bout updating multiple entities in a dataTable?
That's not really a jboss seam issue, it is a JPA (Java Persistence API) issue. As long as your integration test works, so should it when you run with JBoss Seam.
