Thanks for the feedback! Chuck's argument is hard to resist--best accurate data is using the db and using db logic the performance hit shouldn't be terrible. I've implemented a computed field using a @Formula annotation on the spentAmt's getter and this works great--almost. One problem: After I add an Expense (expense edit page) I redirect to my Project screen, but I still see the old calculated value for spentAmt. For some reason the new value reflecting my Expense addition isn't rendered. If I manually refresh the screen using the browser then I do get the correctly computed (new) values. Huh? Any idea why isn't my computed field being refreshed when the page is rendered? Thanks! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4029498#...
