I have a set of jsf components that are statically generated from a set of excel files (they are updated by business people). Each generated file represents a business object that has slightly different data, and all of them belong to a same class.<\/p>\n
In order to render this dynamically, the only solution I found was to set up a bunch of But I found out that the perfomance of this is terrible. I tought that JSF would only render a single component, but it seems that it is rendering all<\/strong> of them and “hiding” the others at runtime.<\/p>\n Is there a more efficient way of achieving my goal? I want to render a single component<\/strong> based on runtime information about a business class (much like an if-then-else), but I can only determine what is the component to render at runtime.<\/p>\n Clarification:<\/strong> what happens is that each component referenced by So if my page is exactly like this:<\/p>\n it will render much<\/em> (around 10x) faster than the initial version, even though the parameters are the same. I suspect that JSF will create the entire component tree and only at runtime it will decide (depending on the supplied parameter) if it will render each other or not.<\/p>\n Edit<\/strong><\/p>\n Almost there.
