Pregunta

Any reason why the displaypage.xhtml does not redirect to the frontpage.xhtml when the "GoBack" button is hit? The browser redirects from the frontpage.xhtml to the displaypage.xhtml but not the other way round.

Thanks

frontpage.xhtml

Solución

The <h:commandButton> tag must be covered by <h:form> tag to be active, and especially if the action attribute of <h:commandButton> contain a dynamic navigation ( e.g: action=#{user.testcase2()} ) .

Else, if this last tag has just a static navigation, (string e.g: action="frontpage" ), then just use the <h:button> as M. @BalusC said, because it doesn't support dynamic navigation.
