request-lifecycle callbacks via view definitions
------------------------------------------------
Key: EXTCDI-46
URL: https://issues.apache.org/jira/browse/EXTCDI-46
Project: MyFaces CODI
Issue Type: New Feature
Components: JEE-JSF12-Module, JEE-JSF20-Module
Reporter: Gerhard Petracek
EXTCDI-11 is based on the event system of cdi
that means esp. in large applications there might be different kinds of
possible problems.
(currently there might be also issues in combination with @View and custom
scopes)
it should be possible to annotate methods with @BeforePhase and @AfterPhase
(methods without parameters or with javax.faces.event.PhaseEvent as parameter).
they will be invoked if the bean is used as page-bean for the current view (see
typesafe view definitions)
@BeforePhase(PhaseId.RESTORE_VIEW) as well as @BeforePhase(PhaseId.ANY_PHASE)
aren't supported.
(in case of restore view you have to use phase-observer-methods (see EXTCDI-11))
examples:
@BeforePhase(RENDER_RESPONSE)
protected void preRendering(PhaseEvent phaseEvent)
{
//...
}
@AfterPhase(PhaseId.UPDATE_MODEL_VALUES)
protected void postModelUpdate()
{
//...
}
