## Class ListFromCollection

- java.lang.Object
- - org.apache.myfaces.trinidad.util.ListFromCollection

-     public class ListFromCollection
      extends Object

  Bean that can dynamically produce Lists from Collections. The Collections must implement size(). Create an instance of this bean as a managed bean:

  ### Example:

        <managed-bean>
          <managed-bean-name>makeList</managed-bean-name>
          <managed-bean-class>
             org.apache.myfaces.trinidad.util.ListFromCollection
          </managed-bean-class>
          <managed-bean-scope>
             request
          </managed-bean-scope>
          <!-- Let's buffer 25 rows at a time (the default is 50) -->
          <managed-property>
            <property-name>size</property-name>
            <value>25</value>
          <managed-property>
        </managed-bean>

         <h:dataTable value="#{makeList.list[someSet]}>
         </h:dataTable>

  Note, though, that it is extremely expensive to use this bean for the items of an tr:forEach (or c:forEach in JSF 1.2 or Facelets).
