Description

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:

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>

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; }
}

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

Steps to reproduce the error:

1. Ensure the selected myfaces.version in the pom.xml is 2.2.8.
2. Start the application and open the respective website.
3. Select c:forEach (non-ajax).
4. Activate the checkbox.
5. 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)
