Class ListFromCollection

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

public class ListFromCollection

extends java.lang.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).
