Subject [jira] [Commented] (TOMEE-1793) PostConstruct and PreRenderView called twice on load
Date Mon, 02 May 2016 09:46:12 GMT

    [ https://issues.apache.org/jira/browse/TOMEE-1793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15266296#comment-15266296
] 

Matthew Broadhead commented on TOMEE-1793:
------------------------------------------

[~romain.manni-bucau] there is the line
{code}
log.log(Level.INFO, "CALLING POSTCONSTRUCT");
{code}
in the PostConstruct method of a ViewScoped ManagedBean.  The stack trace shows that being
called twice?  When I step through in debug the first time it has Request parameters, the
second time it doesn't (which is fair enough because it is ViewScoped) but why would the PostConstruct
be called twice on a ViewScoped bean?

> May have started after recent Oracle java update (1.8.0-92-b14) but suddenly all ManagedBeans
seem to be calling PostConstruct and PreRenderView twice on View load.  Second time it is
called the request parameters are empty.  Result is that any redirect in PreRenderView gets
executed.  Determined second request was a Partial Request so surrounded PreRenderView listener
with
> {code}
> if (!FacesContext.getCurrentInstance().getPartialViewContext().isPartialRequest()) {
> ...
> }
> {code}
