EL expression in expanded attribute of panelMenuGroup
-----------------------------------------------------

                 Key: RF-8547
                 URL: https://jira.jboss.org/jira/browse/RF-8547
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-menu
    Affects Versions: 3.3.3.CR1, 3.3.2.SR1, 3.3.2.GA
            Reporter: Jethro Borsje


I am using an EL expression in the "expand" attribute of a panelMenuGroup which results in the following error:
25-mrt-2010 11:51:16 javax.faces.component.UIInput updateModel
SEVERE: /test.xhtml @82,68 expanded="#{true}": Illegal Syntax for Set Operation

This is my code:
	<rich:panel header="#{navigation.selectedHoofdTab.naam}" headerClass="hoofdTab" bodyClass="hoofdTabContent" style="width: 250px; height: 500px;" id="subtabs">
		<!-- Subtabs -->
		<rich:panelMenu mode="ajax" iconExpandedGroup="disc" iconCollapsedGroup="disc" iconExpandedTopGroup="chevronUp" iconGroupTopPosition="right" iconCollapsedTopGroup="chevronDown"
			topGroupClass="subTab" itemClass="taak" styleClass="subTabContainer">
			<c:forEach items="#{navigation.selectedHoofdTab.subTabs}" var="subTab">
				<rich:panelMenuGroup label="#{subTab.naam}" expanded="#{true}">

					<!-- Taken -->
					<c:forEach items="#{subTab.taken}" var="taak">
						<rich:panelMenuItem label="#{taak.naam}">
							<f:param name="current" value="#{taak.naam}" />
						</rich:panelMenuItem>
					</c:forEach>
					<!-- Einde taken -->

				</rich:panelMenuGroup>
			</c:forEach>
		</rich:panelMenu>
		<!-- Einde subtabs -->
	</rich:panel>

The RichFaces documentation says the following about the "expand" attribute: "If true group will be displayed expanded initially. Default value is "false"". This leads me to believe the attribute is NOT read / write, so why does RichFaces try to set the value?

A similar bug is marked as resolved and has been closed: https://jira.jboss.org/jira/browse/RF-2922, perhaps this is regression?
