Hallo,
in our web-application (JSF2.2 with DaltaSpike) we listen in a PhaseListener
during RESTORE_VIEW on a special url. According to the HTTP-Post data we
initialize a ViewAccessScoped bean and then redirect to a target url using
ExternalContext.redirect(targeturl).
This redirect results in two requests to the target url. Both requests have
different instances of the ViewAccessScoped bean. For this reason the
initialization data gets lost.
How can a redirect be done without having two following requests?
Before migrating from JSF1.2 to JSF2.2 and without using DeltaSpike there was
only one request after redirecting. Threrefore we suppose that this effect
results from deltaspike and the dswid parameter.
For this reason we tried to extend the target url like:
targeturl + „?dswid=“ + viewaccesscopedbean.getDswid()
reading the dswid from deltaspike – WindowContext
With this extension of the targeturl the behaviour is no more predictable. The
redirect sometimes results in two sometimes it results in one request.
Here our java-code:
public class MyTestPhaseListener implements PhaseListener
{
/**
* ViewAccessScoped Bean
*/
@Inject
MyVAccBean myVAccBean;
@Override
public void afterPhase(PhaseEvent event)
{
}
@Override
public void beforePhase(PhaseEvent event)
{
if (event.getPhaseId() == PhaseId.RESTORE_VIEW)
{
ExternalContext extCtx = event.getFacesContext().getExternalContext();
HttpServletRequest request = (HttpServletRequest) extCtx.getRequest();
String currReqUri = request.getRequestURI();
if (currReqUri.indexOf("/initialPage.jsf") > 0)
{
myVAccBean.setValue("some value");
redirectToTargetUrl(event, "targetPage.jsf");
}
}
}
private void redirectToTargetUrl(PhaseEvent event, String tagretUrl)
{
try
{
String encodedUrl = tagretUrl + "?dswid=" + myVAccBean.geDsWindowId();
event.getFacesContext().getExternalContext().redirect(encodedUrl);
}
catch (Throwable e)
{
e.printStackTrace();
}
}
@Override
public PhaseId getPhaseId()
{
return PhaseId.ANY_PHASE;
}
}
