Access a Set with JSF-EL?

Can I access a Set with JSF-EL?

 

I have a datatable with many records. The user is able to update records
in a detail panel. The ids of the updated records are stored in a
HashSet in a backing bean. Now I want to mark all those records that
have been updated by the user.

 

Something like rendered="#{ MyBean.values[record.id] != null } is not
working

 

JSP:

<t:dataTable 

   var="record"

   ...

 

<t:column>

    <h:outputText value="***" rendered="#{ (MyBean.values[record.id]) }
"/>

</t:column>

 

MyBean:

   private Set<String> values = new HashSet<String> ();

   public Set<String> getDocumentIds() {

               return this.values;

   }

#{! empty MyBean.values[record.id]}  should work
