SpEL operators in JSF 2 el

[ufasoli]

Hi I was wondering if it was possible to use some of the SpEL operators in JSF pages. I'm trying to use both the null safe accessor and the T operator but I keep getting exceptions like:

javax.el.ELException: Function ':T' not found 

In the reference documentation I read that since Spring Webflow 2.1 the default el expression parser is SpEL but I suppose this only applies to expressions inside the flow definition file.
So my question is: is it possible to use SpEL in JSF pages and if so how?


here is my webflow config:

<flow-executor id="flowExecutor">
    <flow-execution-listeners>
        <listener ref="securityListener" />
        <listener ref="facesContextListener" />                
        </flow-execution-listeners>
</flow-executor>

    
<flow-registry id="flowRegistry" parent="flowRegistryGenerated"
     flow-builder-services="flowBuilderServices" base-path="/WEB-INF/flows" >
        <flow-location-pattern value="/**/*-flow.xml" />
    </flow-registry>

    
    <flow-registry id="flowRegistryGenerated"
        flow-builder-services="flowBuilderServices" base-path="/WEB-INF/flows-generated" >
        <flow-location-pattern value="/**/*-flow.xml" />
    </flow-registry>


<faces:flow-builder-services id="flowBuilderServices"     development="true"/>

<beans:bean id="facesContextListener" class="org.springframework.faces.webflow.FlowFacesContextLifecycleListener" />

<beans:bean id="securityListener" class="org.springframework.webflow.security.SecurityFlowExecutionListener" /> 

thanks in advance

I'm using :
