how to stop seam auto updating database

[terryb]

I have xhtml form linked to entity which I load with a single record. One of the button on the form is 'Set to Default', which changes value of one of the fields to default and reload the xhtml form to show default value. At this stage seam save values to database too; is it possible to stop that?

I would like user to see the default value but only save to database when Save button is clicked on the xhtml form.

Use manual flush mode and don't call entityManager.flush()

[terryb]

is that the case too when there is no long running coversation and seam managed transactions?

Docs have info about manual trans with BEGIN END annotations only. haven't been able to figure out manual trans in absence of BEGIN END...

components.xml
 <persistence:managed-persistence-context name="entityManager"
 auto-create="true"
 persistence-unit-jndi-name="java:/tisconline-adminEntityManagerFactory"/>

Do it programatically

PersistenceProvider.instance().setManualFlushMode(entityManager);
