anonymous wrote : 1) In JSF for N mutually exclusive 'rendered' conditions they will ALWAYS be evaluated N times!!! Well, sure. But note that a switch statement is also involves n potential evaluations. I'm not sure what the difference is? I guess you can emulate a switch using nested f:subviews. If this particular issue is truly a problem, it is possible to decide which fragment to render in your Java code by using rendered="false" on all N fragments and calling UIComponent.setRendered(true) explicitly before the render phase. anonymous wrote : 2) Even worse there is no syntax to assign columnBean.type to a variable so it will be EVALUATED EACH TIME!!! In components.xml, type: <factory name="columnBeanType" scope="request" value="#{columnBean.type}"/> Perhaps that "trick" addresses your concerns? anonymous wrote : 3) Even worse it will be evaluated using REFLECTION!!! It has been a really long time since a reflective method invocation was significantly slower than a normal method call. This seems to be a red herring. anonymous wrote : 4) JSF will give you temptation to write condition as STRING comparison I don't know what you mean.
