Getting error when binding a dataTable to a backbean compone
Hi,
I have a t:dataTable that binds to a backbean's component as follows:
<t:dataTable id="sessionTable" forceId="true" var="sess" value="#{alertsList}"
border="0" cellpadding="0" cellspacing="0" styleClass="listView" width="100%" renderedIfEmpty="true"
binding="#{alertssearch.sessionTable}" forceIdIndexFormula="#{sess.id}" rowId="#{sess.id}" rowIndexVar="rowIndex"
rowOnClick="selectRow(this.id, #{rowIndex});" />Here is part of the backing bean's code:
@Name("alertssearch")
@Scope(ScopeType.SESSION)
@GALoggedIn
public class GASessionSearchAction {
@In
private Session gadb;
@In(create=true) @Out
private GAFilter sessionfilter;
@In
private GAHostAppInfo hostApp;
@In
private FacesMessages facesMessages;
@Logger
private Log log;
@DataModel
private List<GASession> alertsList;
@DataModelSelection
@Out(required=false)
private GASession selectedSession;
private HtmlDataTable sessionTable;
public HtmlDataTable getSessionTable() {
if (this.sessionTable == null) {
sessionTable = populateSessionTable();
}
return sessionTable;
}
public void setSessionTable(HtmlDataTable sessionTable) {
this.sessionTable = sessionTable;
}
...
The first time I got to the page, the table was rendered fine with no row of course since the data model is empty. When I click on the Search button to execute an ajax request, I got the following exception.
javax.faces.el.EvaluationException: /main.xhtml @106,52 binding="#{alertssearch.sessionTable}": Exception setting property sessionTable of base with class com.ga.riskapp.session.action.GASessionSearchAction$$EnhancerByCGLIB$$bb9eb7c7

Any of you know what's going on?
Thanks.
