---------------------------------------

             Summary: Updating a bound value not possible if input component is within c:forEach
                 Key: MYFACES-4019
                 URL: https://issues.apache.org/jira/browse/MYFACES-4019
             Project: MyFaces Core
          Issue Type: Bug
    Affects Versions: 2.2.8
            Reporter: Johannes Grimm


Updating a value is not possible if the respective input component is within a c:forEach tag.

The server shows a {{javax.el.PropertyNotFoundException}}.

*Example:*

{code:title=View}
<h:form>
	<c:forEach items="#{controller.containers}" var="container" varStatus="status">
		<div>
			<h:selectBooleanCheckbox id="checked_#{status.index}" value="#{container.checked}" />
							
			<h:panelGroup id="infotext_#{status.index}">
				container.checked = #{container.checked}
			</h:panelGroup>
		</div>
	</c:forEach>
	<h:commandButton value="Apply" />
</h:form>
{code}

{code:title=Controller.java}
public class Controller {
	public static final class Container implements Serializable {
		private boolean checked = false;
		
		public final boolean isChecked() { return checked; }
		public final void setChecked(boolean checked) { this.checked = checked; }
	}
	
	private final List<Container> containers = Arrays.asList(new Container());
	
	public List<BooleanValueContainer> getContainers() { return containers; }
}
{code}

A complete example can be found here: [https://github.com/jgrimmwsb/faces-repeater-test].

Steps to reproduce the error:

# Ensure the selected {{myfaces.version}} in the {{pom.xml}} is *2.2.8*.
# Start the application and open the respective website.
# Select _c:forEach (non-ajax)_.
# Activate the checkbox.
# Click _Apply_.

With _MyFaces 2.2.7_ the error did not occur.

The project contains further examples:

* An c:forEach example including an ajaxified version (working with _MyFaces 2.2.7_)
* An ui:repeat (ajaxified) example (working with _MyFaces 2.2.8_)
