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

The same thing works before I integrated the app with Seam.
Any of you know what's going on?
Thanks.
