Re-render JSF page components
I have some components on my JSF page that need to display or hide based on a bean boolean property.
I have tried using the rendered attribute as well as jstl c:if and c:choose. My page displays properly the first time based on the condition, but if i go through a JSF lifecycle and return to the same page, even though the bean boolean value has changed, and displays correctly as a string, the previously rendered or hidden components don't update?
Is there a trick to get this to work?
Thank you!

Re: Re-render JSF page components
Posted by Gert Vanthienen <ge...@skynet.be>.
L.S.,
I have never encountered any problems when using the rendered attribute
for implementing this kind of behavior. Could you post a snippet of the
JSP page code you're using?
