Re: (resolved) Forcing to update
Found a workaround for this issue (and a fairly obvious one at that!)
The answer was passing value-binding expressions (pointing to labels)
instead of the actual labels, when building the collection of
NavigationMenuItems.
This is the only way that I could get a usage such as
<t:panelNavigation2 id="nav1" layout="list" activeItemClass="selected">
<t:navigationMenuItems value="#{menu.panelNavigationItems}" />
</t:panelNavigation2>
to reliably update its labels on each request. This deviates from the
behaviour of similar collection-referencing tags, such as dataTable and
f:selectItems, which grab the collection anew every time.
Cheers,
