[ http://jira.jboss.com/jira/browse/RF-2922?page=comments#action_12412111 ]
Christian Küppers commented on RF-2922:
---------------------------------------
Since value attribute is deprecated, the ValueExpression for expanded should
have the key "value" in bindings and not "expanded".
org.richfaces.taglib.PanelMenuGroupTagBase:
protected void setProperties(UIComponent component) {
super.setProperties(component);
UIPanelMenuGroup panelMenu = (UIPanelMenuGroup) component;
if (_value != null) {
if (_value.isLiteralText()) {
try {
panelMenu.setExpanded(Boolean.parseBoolean(_value.getExpressionString()));
} catch (ELException e) {
throw new FacesException(e);
}
} else {
component.setValueExpression("expanded",
_value);
}
}else{
panelMenu.setExpanded(false);
}
}
Because the method isExpanded in UIPanelMenuGroup looks for the binding "value".
