Hi there! Maybe some can explain this to me - it might be a general JSF misunderstanding I am having.
I'm using t:panelNavigation + t:commandNavigation to have a 'navigation' on every jsf page. When pressing one of the t:commandNavigation items it causes a reload of the current page I am on before executing the action specified. The behaviour I would expect would not be a request to the current page I am on but to the new page w/o rendering the old one. My problem is that the request to the old page causes a query to the database causing performance problems - as it is loading not needed data! I read through the documentation and couldn't find any possible solution (checked the lifecycle in particular: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSFIntro10.html). I think the problem is that the t:commandNavigation needs to be nested in a form that is submitted by clicking on one of the items. Does this cause the whole page to be rerendered? Am I getting anything wrong here? Maybe someone can give me some hints where to look or what might be wrong. Thank you! - Stefan
