Okay, trying to nav to two different places depending upon a variable that gets set by an action. here is the n:nav tag <n:nav outcome="transition" url="#{nid == '0' ? 'home.jsf' : 'task.jsf?id=#{nid}'}" storeMessages="true" /> Now I think that the expression parser is getting confused because there is a #{variable} inside of the outside #{string}. Is there another way to do this? I'm thinking of writing a tag that takes a trueValueVariable and a falseValueVariable and a condition and target. If the condition is true, it assigns the trueValueVariable to the target, else it assigns the falseValueVariable. NOW, the question is will the n:nav tag handle a url="#{target}" where the target was the name of the target variable in the previous assignment via the action?
