problem with h:selectBooleanCheckbox in rich:dataTable

[crisyag]

I have the following rich:dataTable

<rich:dataTable id="groupContacts" value="#{BackingBean.allContacts}" var="contact">
 <rich:column>
 <h:selectBooleanCheckbox value="true" />
 </rich:column>
 <rich:column>
 <h:outputText value="#{contact.name}" />
 </rich:column>
</rich:dataTable>

when the table is rendered, h:selectBooleanCheckbox is not checked. Does anyone know how to fix it? I'm using Richfaces 3.1.2.SP1 and Myfaces 1.1.5.

Thanks,

Cristiane Yaguinuma.

known bug. Will works fine with EL binding.

Thanks Gena, it worked fine
Now I have another problem when I need to change the value of h:selectBooleanCheckbox dynamically. Here is the code:

<h:selectOneMenu id="selectGroup" valueChangeListener="#{ContactList.showGroupContacts}">
 <f:selectItems value="#{ContactList.selectGroupList}" />
 <a4j:support event="onchange" reRender="groupContactsPanel"/>
</h:selectOneMenu>

<a4j:outputPanel id="groupContactsPanel">
 <rich:dataTable id="groupContacts" value="#{ContactList.allContacts}" var="contact">
 <rich:column>
 <h:selectBooleanCheckbox value="#{contact.check}" />
 </rich:column>
 <rich:column>
 <h:outputText value="#{contact.name}" />
 </rich:column>
 </rich:dataTable>
</a4j:outputPanel>

The method showGroupContacts change the value of contact.check to true considering the contacts of the group chosen in h:selectOneMenu. However, when the datatable is rendered, h:selectBooleanCheckbox values do not change, even though they are changed by method showGroupContacts:

public void showGroupContacts(ValueChangeEvent event) {
 String selectedGroup = (String) event.getNewValue();

 List groupContacts = (List) this.groups.get(selectedGroup);
 for (Iterator i = groupContacts.iterator(); i.hasNext();) {
 Contact c1 = (Contact) i.next();
 for (Iterator j = allContacts.iterator(); j.hasNext();) {
 Contact c2 = (Contact) j.next();
 if (c1.getId() == c2.getId())
 c2.setCheck(true);
 }
 }

}

Is there any problem with the code? How can I fix it?
Thanks a lot for the help,
