Läuft JSF-Seite, Fehler: Fehler beim Parsen den Ausdruck [${LogModel.getLogList()}]?

Ich bin mit jsf 2 zusammen mit tomcat 6, und ich bin versucht, diesen code ausführen, werden die in einer .xhtml-Seite, die ich habe:

    <h:dataTable value="${LogModel.getLogList()}" var="c"
            styleClass="order-table"
            headerClass="order-table-header"
            rowClasses="order-table-odd-row,order-table-even-row"
        >

Ich habe die Klasse logmodel und die Methode getLogList(), aber ich bekomme diese Fehlermeldung wenn ich starten Sie die Seite:

/testLog.xhtml @20,8 value="${LogModel.getLogList()}" Fehler beim analysieren des Ausdrucks [${LogModel.getLogList()}]

Hier ist das komplette log von dem problem:
