Are ViewScoped beans serialized to the page when client state saving is turned on?

问题 We have client state saving turned on and use ViewScoped backing beans. When client state saving is turned on and we are using a ViewScoped bean, is the ViewScoped bean serialzied to the page or is it say, stored in session with a token/key that is serialized to the page (so that the page can recall the bean from session if the page is posted-back to itself) A concern here might be that, if it is serialized, then we might want to then worry about not storing large instance variables on the

由 廉价感情. 提交于 2020-01-01 05:00:07
问题 I'm planning to convert a web app from using JSF managed bean to using CDI managed beans. I know I'll need to do below: Add a empty beans.xml file in WEB-INF.

How to redirect to the login page when the session expires?

由 こ雲淡風輕ζ 提交于 2020-01-01 03:46:33

I think it is becasue there are no HttpServletRequest and HttpServletResponse objects. I also tried it using a PhaseListener , but it results in a "too many redirects" error in the webbrowser. public class SessionListener implements

Modifying JSF Component Tree in PhaseListener

由 蹲街弑〆低调 提交于 2019-12-31 04:09:09
问题 I'm having an issue. I've implemented a PhaseListener, which is meant to add a style class to any UIInput components in the tree that have messages attached to them, and removes the style class if it doesn't have any messages attached to them. The PhaseListener runs in the RENDER_RESPONSE phase, and does it's work in both the beforePhase and afterPhase methods while debugging.
