Hello, world!
</rich:panel>
<div style="clear:both"></div>
</f:view>
</ui:define>
</ui:composition>It works fine if I take out the reference to blogTopicsUser
That object is built using the following:
@Factory("blogTopicsUser")
public User getUser() {
if(username == null)
throw new EntityNotFoundException("Username not set.", User.class);
if(u == null)
userDAO.findUserByUsername(username);
return u;
}The odd thing is that I can see the query running, i'm inclined to say that the url rewriting as stopped working. the url is something like http://localhost:8080/bloggers/JohnA, and in pages.xml I see..
<page view-id="/blog/view.xhtml">
<param name="username" value="#{topicManager.username}"/>
<rewrite pattern="/bloggers/{username}" />
</page>the worst part is that this used to work just fine. haven't changed the code.
