JSF Back Button [duplicate]

This question already has answers here: back commandbutton in jsf 开发者_运维问答 (5 answers) Closed 8 years ago.

How do I make a link which navigates the user back one page (i.e. same as clicking browser back)?

Thanks.

To the point: just remember the request URL or the JSF viewId of the previous page so that you can use it in the href or value of the output/commandlink. There are several ways to achieve it, depending on how you're actually navigating through the pages and how "jsfish" you want to achieve it. You could pass it as a request parameter by f:param in h:outputLink, or you could set it as a bean property by f:setPropertyActionListener in h:commandLink, or you could create a PhaseListener which remembers the viewId and make use of navigation cases, or you could grab the -much less reliable- JavaScript history.go() function.
