Hi, I'm using the Hibernate Tools Code Generation to generate a seam application. It's working fine but I've got a problem when navigating through the results of a research. My case is : In the "Find page", I fill in criterias, then click on "Find". I get several answers and the button "next page" is activated. If I click about 10 or 15 times on the "Next page" or the "Previous page" button, I get an error. It doesn't appear each time at the same moment and the error is different each time, of type : anonymous wrote : javax.faces.FacesException: Cannot get value for expression '#{collectivitesSelector.createEnabled}' or anonymous wrote : 11:13:57,442 ERROR [[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception | javax.faces.FacesException: Cannot get value for expression '#{collectivites.departements.dptidt}' or anonymous wrote : javax.servlet.ServletException: Cannot get value for expression '#{collectivites.coltlc}' (My object name is "Collectivites") I'm using : Eclipse 3.2.1 Hibernate tools 3.2.0.beta9a Seam 1.1.5 JBoss 4.0.5 Have you got any idea on how to solve this please?
