[jboss-user] [JBoss Seam] - Conditionally Rendering Parameters

I have a seam-gen page with the following in the pages.xml file. | <page view-id="/admin/manage-customers.xhtml"> | <param name="firstResult" value="#{customerList.firstResult}"/> | <param name="order" value="#{customerList.order}"/> | <param name="from"/> | <param name="firstName" value="#{customerList.customer.firstName}"/> | <param name="lastName" value="#{customerList.customer.lastName}"/> | <param name="emailAddress" value="#{customerList.customer.emailAddress}"/> | </page> | When I enter a value in the form for the first name, all of the parameters are rendered in the URL: http://localhost:8080/admin/manage-users.html?emailAddress=&firstName... This triggers my model validation and I get the error that the Email Address must be well formed. If I manually remove the emailAdress param all works well. How do I prevent the empty email param from being rendered? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075018#...
