How to read values of dynamic UI elements in a backing bean?

Question

Hi, I have an ADF page where some of the UI elements (in this case, checkboxes) are dynamically rendered as such:
<af:forEach var="row" items="#{backing_testPage.userList}">
<af:selectBooleanCheckbox id="checkbox" value="#{row.id}"
text="#{row.name}" selected="#{row.userSelected}"/>
</af:forEach>
I am wondering how can I read the values of these checkboxes in my page's backing bean. It does not seem possible to specify a distinct binding value for the selectBooleanCheckbox elements in order to tie them to a CoreSelectBooleanCheckbox variable in my backing bean (so that I could check whether the checkbox is selected or not).
When the page gets rendered, I did see that the checkboxes get assigned distinct ids like checkbox_1, checkbox_2, checkbox_3, etc... Not sure if that would help with this.
Would appreciate any tips on this as I've been struggling with this for awhile. Thanks!

You probably would do better with a SelectManyCheckbox. Here's how:
In your backing bean you need:
private String[] usernames;
public String[] getUsernames () {
  return usernames;
public void setUsernames (String[] _usernames) {
  usernames = _usernames;
}In your page:
<af:selectManyCheckbox value="#{backing_testPage.usernames}">
  <f:selectItems value="#{backing_testPage.userList}"/>
</af:selectManyCheckbox>When the form is rendered any strings in the usernames array that are in the userList will be checked. When submitted, any checked items will be in the array.
