I have two selectOneMenu controls on my Seam page. One uses an AJAX call to re-render the employees associated with the division. All works well the first time I change a division (Note... No matter what division I select the first time, the other control appears to re-render correctly). The second time I change the division I get this error... No matter what division I select. sourceId=j_id10:j_id25[severity=(ERROR 2), summary=(value is not valid), detail=(value is not valid)] The control is re-rendered, but with incorrect information. I was assuming that the selected item was not in the re-rendered list, so I created an Employee object with a "0" employeeID. I then made sure the employee was included in each rendered list and I made sure that employee was the one that was selected each time I changed division. That did not make a difference. | Division : | <h:selectOneMenu value="#{payrollExport.selectedClient}"> | <s:selectItems value="#{payrollExport.clients}" var="c" label="#{c.pluses}#{c.description}" /> | <f:converter converterId="clientConverter" /> | <a:support event="onchange" actionListener="#{payrollExport.refreshEmployees}" reRender="employees" /> | </h:selectOneMenu> | | Employee : | <h:selectOneMenu id="employees" value="#{payrollExport.employee}"> | <s:selectItems value="#{payrollExport.employees}" var="e" label="#{e.lastName}, #{e.firstName}" noSelectionLabel="All Employees" /> | <f:converter converterId="employeeConverter" /> | </h:selectOneMenu> | I have overriden the Employee "equals" and "hashCode" methods. The equals method compares the employeeID (A unique int from a database table) and the hashCode method simply returns the employeeID. Two objects with the same employeeID should be equal.
