[jboss-user] [JBoss Seam] - Selecting from a dataTable works randomly

I have a dataTable with a control variable named "report". The dataTable is populated from a collection of EJB3 entities. Upon clicking one of the links in the table the user is transferred to another view which accepts an @In parameter named report. This view creates another dataTable (in the form of a UIData object) and displays it. All of this works only once -- all subsequent attempts to click my way through the tables fail miserably with an exception in com.sun.facelets.el.LegacyValueBinding.setValue. The first dataTable looks like this: <h:dataTable var="report" value="#{reports}" id="list"> | <h:commandLink rendered="#{report.ready}" action="#{showreport.show}" value="Show report"/> | </h:dataTable> | The #{showreport.show} action does nothing but creating a UIData object marked with an @Out annotation and some data values (a List also marked with an @Out). The UIData object is then displayed by the following tag: <h:dataTable binding="#{showreport.dataTable}" value="#{showreport.tableRows}"/> As I said before, this scheme works perfectly until I return to the first dataTable and click on the "Show report" link again. The second (and any next) time I get this exception: javax.faces.el.PropertyNotFoundException: /report/showreport.xhtml @22,97 binding="#{showreport.dataTable}": Bean: org.javassist.tmp.java.lang.Object_$$_javassist_187, property: dataTable at com.sun.facelets.el.LegacyValueBinding.setValue(LegacyValueBinding.java:72) at org.apache.myfaces.application.ApplicationImpl.createComponent(ApplicationImpl.java:443) at org.jboss.seam.jsf.SeamApplication11.createComponent(SeamApplication11.java:78) at com.sun.facelets.tag.jsf.ComponentHandler.createComponent(ComponentHandler.java:237) [...] Creating a setter for the dataTable property does not help much -- the same exception is thrown. How do I ensure that the results of calling an action are consistent throughout the use of the application? I'm using Seam 1.2.1.
