Seam+dataTable+methods with parameter

[.:lexx:.]

Does anybody knows how to implement dataTable with columns which values evaluated in method with parameters:

<ice:dataTable id="foundPackets" value="#{foundPackets}" var="packet" columnClasses="basicColumn"
 rowClasses="basicTableRow1, basicTableRow2">
 <ice:column>
 <f:facet name="header">Time</f:facet>
 <ice:outputText value="#{packet.date}">
 <f:convertDateTime pattern="#{uiConstants.defaultPattern}"/>
 </ice:outputText>
 </ice:column>

 <ice:column>
 <f:facet name="header">SMSC</f:facet>
 <ice:outputText value="#{deliveryStatusHelper.isDeliveredToSmsc(packet.deliveries)}"/>
 </ice:column>
</ice:dataTable>

DeliveryStatusHelper.java:

@Scope(ScopeType.SESSION)
@Name("deliveryStatusHelper")
public class DeliveryStatusHelper {
 public boolean isDeliveredToSmsc(DeliveryEvent[] deliveryEvents) {
 for (DeliveryEvent deliveryEvent : deliveryEvents) {
 if (deliveryEvent.getStatus() == DeliveryStatus.SMSC.getCode()){
 return true;
 }
 }
 return false;
 }

The main problem is inoperability of construction "#{deliveryStatusHelper.isDeliveredToSmsc(packet.deliveries)}".
Also i tried to use this construction:
<h:outputText value="Yes" rendered="#{deliveryStatusHelper.isDeliveredToSmsc(packet.deliveries)}"/>
But this one ends with parse exception:

Caused by: javax.el.ELException: Error Parsing: #{deliveryStatusHelper.isDeliveredToSmsc(packet.deliveries)}

I asked the same question a few weeks ago. JSF distinguishes between value and method expressions. The seam enhancements are for method expressions, but the places where you're using it are evaluated as value expressions.
