      Description

      The current tx propagation types for use with @Transactional are the following:

      REQUIRED, MANDATORY, SUPPORTS, NEVER;

      Here is a comment from the TransactionalPropagationType enum class:

      • Transaction propagation strategies for Seam JavaBean components. Note that unlike EJB3 components, there are no strategies for suspending transactions.

      Please add REQUIRES_NEW and NOT_SUPPORTED. I am unable to solve my functional requirement of calling a webservice which inserts into remote db (which does not require a tx) and inserting into multiple local db tables (requires tx) using JavaBean components and Seam @Transactional. The requirement is that even if the webservice call fails, the local db inserts should continue and succeed (i.e. no atomicity, no rollback).

      There is an action method in my JavaBean Seam component that is invoked from a commandButton in JSF page. Then there are two private methods that are invoked from that public method. One requires tx support, the other does not. With EJB3, I would simply use NOT_SUPPORTED for one and REQUIRES_NEW for the other. Now using JavaBeans and @Transactional, I cannot solve my problem in terms of tx support requirements. @Transactional only works on public methods.

      I tried recalling the component's private method (now refactored to public with @Transactional) using Component.getInstance("foo"); but that did not work.

      Spring has robust tx support like EJB 3. Seam needs to be ramped up in terms of tx support for JavaBean components.
