<ui:param and caching

Question

I have the following thing:

<ui:param name="randomVideo" value="#{bean.randomVideo}" />
<a href="#{randomVideo.link}">#{randomVideo.text}</a&></pre>

Because <ui:param> does not cache the variable, Bean.getRandomVideo() is called twice, and the worst part is that the .text and .link are from different videos. I have already tried <c:set and <f:param. They both do not set the variable, maybe because I'm with facelets (JSF2).

Any ideas?

Getters are supposed to be real getters, not containing any logic. So:

• make your bean @RequestScoped
• initialize the randomVideo field in @PostConstruct
• let the getter only retrieve the randomVideo field of the bean.

Actually, I had to move my logic to a new bean, but if we disregard the extra code this solution was better than mine - put the random video in the request and check whether there was anything in the request in the getter) – Barsac
