Hello I've just upgraded icefaces 1.7.1 to 1.7.2 and started to get javax.faces.application.ViewExpiredException exceptions after clicking twice on the same link. I'm using JBoss Seam 2.0.2 and I suppose that it is some stupid mistake I've made during upgrade but I can't figure out what. I've just replaced three jars with newer ones (icefaces.jar, icefaces-comps.jar and icefaces-facelets.jar. Is there anything more I should do? When I switch back to 1.7.1 everything works fine as before.
